ABSTRACTPurpose: To evaluate the long-term outcome of active choroidal neovascularization (CNV) in punctate inner choroidopathy (PIC) or multifocal choroiditis (MFC) after intravitreal bevacizumab treatment.Methods: Retrospective study of consecutive patients of PIC/MFC complicated with active CNV. Outcome measures included best-corrected visual acuity (BCVA), total number of intravitreal injections of bevacizumab and recurrence of CNV. Correlation analysis was performed to find the correlation of various clinical factors and final BCVA.Results: There were 23 eyes in 22 patients with a mean age of 33.22 years included in this study. The mean duration of follow-up was 6.48 years. Improvement of BCVA was noted through the first 3 years and at the final follow-up. BCVA at 1, 6, 12 months and recurrence of CNV were correlated with final BCVA.Conclusion: Most patients of PIC/MFC complicated with CNV managed with intravitreal bevacizumab had improved BCVA over 4 years. 相似文献

AIM: To evaluate the efficacy and safety of a combined treatment for myopic choroidal neovascularization (CNV) using photodynamic therapy (PDT) and intravitreal bevacizumab and to compare it with intravitreal bevacizumab monotherapy.METHODS: Thirty-four eyes with angiographic evidence of myopic CNV were randomly divided into two groups:17 were treated with one intravitreal bevacizumab injection (1.25 mg) and low-fluence-rate PDT within seven days of the injection (Group A). The other 17 received monotherapy with bevacizumab injections (Group B). Clinical evidence of complications, best corrected visual acuity (BCVA) and fluorescein leakage were evaluated. BCVA and optical coherence tomography (OCT) were evaluated monthly. The timepoints follow-up was established at 6 and 12mo. All patients were retreated following a PRN protocol.RESULTS:A total of 34 eyes of 34 patients (26 women and 8 men) with a mean age of 62.35 years were included. In Group A (17 eyes) the mean BCVA increased from 0.55±0.13 logMAR before the treatment to 0.40±0.09 logMAR at the 12mo follow-up (P<0.01). In Group B (17 eyes) the mean BCVA increased from 0.60±0.11 logMAR before the treatment to 0.55±0.12 logMAR at the 12mo follow-up (P<0.01). There was no statistically significant difference between the two groups in terms of LogMar visual acuity. In Group A the mean number of combined treatments was 1.8±0.11 per patient; in Group B the mean number of intravitreal bevacizumab injections was 3.1±0.08 per patient. The number of treatments was significantly fewer in Group A (P<0.01). No local or systemic side effects occurred among any of the patients treated in this study.CONCLUSION:The combination of anti-angiogenic injections and PDT appears to be a safe and effective option for myopic CNV treatment and allows for a significant reduction of intravitreal injections. 相似文献

PURPOSE: This study aimed to assess the pharmacodynamic profile of intravitreal bevacizumab in relation to best corrected visual acuity (BCVA), foveal thickness, and other aspects of macular morphology after intravitreal injection of bevacizumab in eyes with subretinal choroidal neovascularization (CNV). METHODS: A retrospective observational, uncontrolled case series including 26 eyes in 25 patients followed for up to 6 months after intravitreal injection of bevacizumab 1 mg repeated as deemed necessary after monthly assessments by biomicroscopy, optical coherence tomography, colour fundus photography, fluorescein angiography and BCVA determination. At follow-up, cases were classified by morphological treatment response (reduction or elimination of pathological neovascular leakage, retinal thickening or serous retinal detachment) or absence of response (deterioration or lack of improvement). Primary disease entities included age-related macular degeneration (22 eyes, four of which had evidence of retinal angiomatous proliferation), idiopathic peripapillary neovascularization (one eye), and angioid streaks (three eyes in two patients). RESULTS: One month after the first injection, apparent morphological improvement was observed in 24/26 eyes and mean BCVA had improved by 3.1 +/- 7.8 letters (p = 0.05). Of these 24 responders, which included all primary diagnoses, 11 (46%) demonstrated BCVA improvement of >or= 5 letters. The two non-responders (7.7%) had lost > 3 lines of vision at 2 months follow-up. Overall, 18 eyes completed 6 months follow-up, with a mean BCVA improvement of 0.5 +/- 12.7 letters, and 22 eyes completed 3 months follow-up, with a mean BCVA improvement of 2.0 +/- 11.0 letters. Two months after the first injection, 11 (46%) of the 24 responders demonstrated signs of recurrent CNV activity, defined as decreased BCVA and/or increased retinal thickness and/or fluorescein angiographic CNV leakage. No serious drug-related adverse events were observed during the course of the study. CONCLUSIONS: Overall mean BCVA remained stable throughout the study. Morphological signs of reduced CNV activity were seen in the majority of eyes at 2-4 weeks after intravitreal bevacizumab injection. Half the responders showed signs of renewed CNV activity at 2 months after their first injection. All first-injection responders were also second-injection responders. 相似文献

Purpose To investigate the 6-month safety profile and clinical outcomes of intravitreal bevacizumab for treating subfoveal choroidal
neovascularization (CNV) in age-related macular degeneration (AMD).
Methods We performed a prospective nonrandomized interventional study of 40 consecutive patients (40 eyes) with subfoveal CNV due
to AMD. Patients underwent standard ophthalmic examination, optical coherence tomography, and fundus fluorescein angiography.
All patients were administered one or more intravitreal injections of bevacizumab (1.25 mg) as primary therapy. Outcomes were
also analyzed in subgroups based on lesion type (classic or occult) and lesion size (≤3000 μm or >3000 μm).
Results At the 6 months’ follow-up, mean best-corrected visual acuity (BCVA) improved from 20/160 to 20/100 (P = 0.014), and the mean contrast sensitivity improved from 0.38 to 0.62 (P = 0.001). The mean greatest linear diameter and mean central macular thickness significantly decreased from 3.79 mm to 2.4
mm (P = 0.0001) and from 438.5 μm to 363 μm (P = 0.0001), respectively. Visual acuity gain of 15 letters or more was seen in 20% of patients, and the gain was more in the
small-lesion subgroup (31.5%) than in the large-lesion subgroup (9.5%). No significant adverse effects were observed.
Conclusion Intravitreal bevacizumab is a safe and effective modality for treatment of CNV secondary to AMD. A significant improvement
in BCVA with intravitreal bevacizumab was observed for all lesion types. 相似文献

Background A novel alternative for combined treatment using verteporfin photodynamic therapy (PDT) has emerged as preliminary safety
and efficacy data of the intravitreal use of the anti-angiogenic bevacizumab became available. In the current study we investigate
the feasibility of intravitreal bevacizumab combined with verteporfin PDT for the treatment of choroidal neovascularization
(CNV) secondary to age-related macular degeneration (AMD).
Methods A single-centre, prospective, open-label study of 11 patients with documented CNV progression after PDT treatment who underwent
combined PDT and intravitreal injection of 1.5 mg of bevacizumab was undertaken. Standardized ophthalmic evaluation was performed
at baseline and at weeks 1, 2, 12 and 24. Clinical evidence of complications and changes in logarithm of the minimum angle
of resolution (logMAR) best-corrected visual acuity (BCVA) using Early Treatment Diabetic Retinopathy Study (ETDRS) charts
and in fluorescein leakage from CNV were evaluated.
Results The mean (±SD) age of the 11 patients was 74 (±5) years. Seven eyes had been treated with one previous PDT session and four
eyes had two previous PDT sessions. The mean baseline logMAR ETDRS BCVA was 1.031 (Snellen equivalent, 20/200−2). At follow-up weeks 1, 2, 12 and 24, the mean logMAR ETDRS BCVA (Snellen equivalent) was 0.944 (20/160−2), 0.924 (20/160−1), 0.882 (20/160+1), and 0.933 (20/160−2), respectively. The change in BCVA from baseline was significant at each study follow-up interval (P ≤ 0.001); at 12 and 24 weeks, the mean change in BCVA from baseline was an improvement of 1.49 and of 0.98 ETDRS line, respectively.
Fluorescein leakage from CNV was absent in all eyes at week 12. One additional treatment session was required in seven (63.6%)
eyes at week 24 due to recurrent fluorescein leakage from CNV (“minimum” [<50% of the leaking area noted at baseline], n = 4; and “moderate” [>50% of the leaking area noted at baseline], n = 3). No progression of the neovascular lesion was observed at week 24. No safety issues were identified throughout the period
of the study.
Conclusions The overall changes in vision and fluorescein leakage from CNV throughout the study suggest that a possible synergistic effect
may arise from the combination of intravitreal bevacizumab with verteporfin PDT for the treatment of neovascular AMD.
In terms of funding, this was an investigator’s driven study. 相似文献

Purpose: To evaluate the efficacy and safety of intravitreal bevacizumab at one year follow‐up, for the treatment of choroidal neovascularization (CNV) associated with angioid streaks. Methods: A retrospective case series of eighteen eyes of 17 patients with CNV secondary to angioid streaks treated with intravitreal bevacizumab between October 2006 and May 2008. Ophthalmic evaluation including best corrected visual acuity (BCVA), slit lamp biomicroscopic examination, optical coherence tomography (OCT) and fluorescein angiography, was performed before and after treatment. Retreatment was given every 4–6 weeks in case of persistent symptoms or CNV activity on OCT. Main outcome measures were changes in BCVA and central retinal thickness on OCT. Results: The mean number of injections was 4.8 at 1 year. Twelve eyes (66.6%) received five injections or more. The mean BCVA at baseline was 20/80 (range 20/400 to 20/32) and improved to 20/44 (range 20/160 to 20/20) at 1 year (p = 0.014). The BCVA improved by three or more lines in eleven eyes (61.11%) and remained within two lines of baseline in seven eyes (38.8%). Mean central retinal thickness was 404.2 μm (range 160–602 μm) at baseline and decreased to 300.5 μm (range 150–523 μm) at 1 year (p = 0.022). No ocular or systemic complications were noted. Conclusion: The 1‐year outcomes suggest intravitreal bevacizumab to be a promising treatment for CNV associated with angioid streaks, resulting in both functional and anatomical improvements. Repeated injections are needed to maintain these results. Further long term studies are required to confirm these findings. 相似文献

Aim
This systematic review assesses the prognostic factors for intravitreal bevacizumab injection (IVB) in the treatment of choroidal neovascularization (CNV) due to pathological myopia.Methods
The literature searches were performed in Ovid Medline, EMBASE and CENTRAL. Relevant studies with prognostic data on best corrected vision acuity (BCVA) after intravitreal bevacizumab injection were included for review. Two reviewers participated in the data retrieval and independently assessed each included study.Results
A total 252 articles were retrieved, including 16 studies containing the most updated and complete data on prognostic factors for neovascularization due to pathological myopia treated by intravitreal bevacizumab injection. A great number of quantitative, clinical, and treatment-related factors were determined to have a positive influence on vision outcome after intravitreal bevacizumab.Conclusion
A lower rate of development of chorioretinal atrophy, smaller pretreatment CNV size, and younger age were indentified as the most consistently significant prognostic factors affecting the efficacy of IVB in eyes of myopic CNV and were associated with improved BCVA. A worse BCVA after IVB in eyes with myopic CNV probably was associated with subfoveal CNV, lower baseline BCVA, longer duration of CNV, incomplete regression of CNV, subretinal hemorrhage, and previous PDT treatment. No apparent association were observed between the refraction error, axial length, lens status and change in BCVA after IVB. We indentified significant prognostic factors in this systematic review study that might allow for the selection of patients with myopic CNV which are most likely to benefit from IVB. 相似文献8.

PURPOSE: To evaluate the efficacy of intravitreal injection of bevacizumab combined with photodynamic therapy (PDT) for the treatment of occult choroidal neovascularization (CNV) associated with serous pigment epithelium detachment (s-PED) due to age-related macular degeneration (AMD). METHODS: In this retrospective study, six patients (six eyes) with subfoveal occult CNV associated with s-PED due to AMD were treated with intravitreal bevacizumab combined with PDT. All patients were treated at baseline with PDT followed by intravitreal bevacizumab 1.25 mg 1 hour later. Afterwards, according to the findings of optical coherence tomography and fluorescein angiography, repeat bevacizumab injections were given, if necessary, monthly for three doses followed by further doses every 3 months. PDT was repeated every 3 months according to the same criteria. Follow-up time was 9 months. RESULTS: All patients completed their treatment during the first 3 months from baseline. Best-corrected visual acuity (BCVA) improved or remained stable related to the baseline values in all patients at the end of the follow-up time. Mean BCVA improved from 20/67 to 20/42. S-PED and subretinal fluid decreased or disappeared. The mean central 1-mm retinal thickness was reduced from baseline value for the 9-month follow-up period by 128 microm. CONCLUSION: Intravitreal bevacizumab combined with PDT seems to be a promising treatment with good functional and anatomical results for occult CNV associated with s-PED due to AMD. 相似文献

The purpose of this article is to describe functional and morphological short-term results in patients with exudative age-related
macular degeneration (AMD) of all subtypes, treated with intravitreal bevacizumab versus intravitreal ranibizumab. This was
a retrospective case-controlled series of 30 patients treated with intravitreal bevacizumab and 30 patients treated with intravitreal
ranibizumab for exudative AMD. All patients received three initial injections every 4 weeks. Best corrected visual acuity
(BCVA) as well as greatest linear dimension (GLD) of the CNV in fluorescein angiography and central retinal thickness (CRT)
in optical coherence tomography (OCT) were monitored 2–4 months after last injection. BCVA stabilized and slightly increased
from logMAR 0.74 to 0.62 in the bevacizumab group, and from logMAR 0.76 to 0.58 in the ranibizumab group (P < 0.05 for each group). No statistical difference was seen between both groups at any time-point. CRT was significantly reduced
in both groups at last follow-up. In contrast, GLD did not change significantly. Patients with exudative AMD of all subtypes
benefit from intravitreal anti-VEGF injections. No significant difference between bevacizumab and ranibizumab is seen in the
short-term follow-up. 相似文献

Background: The recent discovery of vascular endothelial growth factor and its role in the pathogenesis of ocular neovascularization has led to the development of new pharmacological agents that could block its action. This study was carried out to investigate the effect of intravitreal injections of bevacizumab on choroidal neovascularization (CNV) associated with pathological myopia.Methods: We retrospectively reviewed the charts of all patients who had CNV secondary to pathological myopia and who had been treated with intravitreally administered bevacizumab between November 2005 and April 2007 at Notre-Dame Hospital in Montréal, Québec. Data on best-corrected visual acuity (BCVA), previous treatments, number of injections, fundus photography, and fluorescein angiography were collected.Results: Ten eyes from 9 patients were followed for a mean period of 9.7 (range 2.5-14) months.At baseline the mean (SD) logMAR BCVA was 0.62 (0.25) (Snellen equivalent 6/24). The mean number of injections per eye was 2.6 (range 1-5). At the end of the study the mean (SD) logMAR BCVA had significantly improved to 0.26 (0.16) (Snellen equivalent 6/10.5; p < 0.001).Vision improved by a mean of 3.9 (range 0-7) lines on the Snellen visual acuity chart. Leakage from the CNV on fluorescein angiography had resolved in 7 of the 10 eyes and was reduced in the 3 other eyes. No drug-related side effects or complications were observed during the follow-up period.Interpretation: Intravitreal injection of bevacizumab appears to be a safe and effective treatment alternative for CNV associated with pathological myopia. 相似文献

Background: Submacular haemorrhage may occur following intravitreal bevacizumab injection for large occult choroidal neovascularization (CNV) in age‐related macular degeneration (AMD). We report the occurrence of submacular haemorrhage following intravitreal ranibizumab compared with intravitreal bevacizumab for large occult CNV in AMD. Methods: Retrospective, comparative evaluation of two interventional case series. Evaluation of consecutive patients with occult CNV ≥ 15 mm2 treated with intravitreal bevacizumab (n = 14) and intravitreal ranibizumab (n = 22) over a 2‐year period within a single institution. Postoperative submacular haemorrhage, Early Treatment Diabetic Retinopathy Study‐derived visual acuity, preoperative blood pressure and anticoagulant use were noted. The two groups were compared using Fisher's exact test. Results: The mean surface area of occult CNV at presentation was 20.9 ± 5.4 mm2 in the bevacizumab group and 24.0 ± 11.0 mm2 in the ranibizumab group. Fresh submacular haemorrhage was seen in 4 out of 14 patients following bevacizumab compared with 0 out of 22 patients following ranibizumab (P = 0.017, odds ratio = 19.29). Mean preoperative blood pressures were very similar between the groups. 28.6% of patients in the bevacizumab group were on oral anticoagulants compared with 31.8% in the ranibizumab group. None of the patients who developed postoperative haemorrhage were on anticoagulants. Conclusions: Acute submacular haemorrhages appear to be a significant adverse event following intravitreal bevacizumab in occult CNV ≥ 15 mm2. Intravitreal ranibizumab appears to have a significantly lower incidence of postoperative submacular haemorrhage in occult CNV ≥ 15 mm2. Larger studies are required to identify the most appropriate agent for the treatment of large occult CNV. 相似文献

OBJECTIVE: To assess the effects of intravitreal bevacizumab injection as primary treatment of inflammatory choroidal neovascularization (CNV). METHODS: Data for nine consecutive patients with newly diagnosed inflammatory CNV who were treated with intravitreal bevacizumab (1.25 mg) injection were reviewed retrospectively. Main outcome measures were best-corrected visual acuity, foveal thickness measured by optical coherence tomography (OCT), and complete resolution of CNV. RESULTS: CNV resolved completely in 9 (100%) of 9 affected eyes. At the last examination, visual acuity was improved in 8 eyes (88.8%), stable in 1 (11.2%), and worse in 0. Over a mean follow-up of 7.1 months (range, 6-10 months), 7 eyes received 1 injection, 1 eye developed CNV recurrence and required a second injection, and 1 eye required a third injection. Foveal thickness by OCT decreased significantly (P = 0.049) after treatment. CONCLUSION: In this small case series of eyes with limited follow-up, intravitreal bevacizumab injection for treatment of inflammatory CNV was found to be safe and was associated with favorable visual outcomes for both subfoveal and juxtafoveal or extrafoveal inflammatory CNV. 相似文献

PURPOSE: To assess the role of bevacizumab in inflammatory ocular neovascularization. DESIGN: Retrospective, multicenter, consecutive case series of inflammatory ocular neovascularization. METHODS: Patients with inflammatory ocular neovascularization of varying causes for whom standard therapy failed were treated with intravitreal injection of bevacizumab. Main outcome measures included improvement of best-corrected visual acuity (BCVA) expressed in logarithm of minimum angle of resolution units, response of inflammatory ocular neovascularization by funduscopy and angiography, and decrease in central foveal thickness as measured by optical coherence tomography at the three-month follow-up. RESULTS: At the three-month follow-up, 84 eyes of 79 patients had been treated with a mean of 1.3 injections (range, one to three). Thirty-four eyes showed juxtafoveal choroidal neovascularization (CNV), 34 eyes showed subfoveal CNV, eight eyes showed peripapillary CNV, and 11 eyes showed neovascularization of the disc (NVD) or neovascularization elsewhere (NVE). BCVA improved 2.4 lines from 0.68 (6/28 or 20/94) to 0.44 (6/17 or 20/55) (P < .001). BCVA improved by one to three lines in 34.5% of the eyes, by four to six lines in 16.7% of the eyes, and by more than six lines in 14.2% of the eyes. Function was unchanged in 23.8% of the eyes. BCVA worsened in 10.7% (zero to three lines in 7.1%, more than four lines in 3.6%). Central foveal thickness decreased from baseline 346 to 252 microm (P < .001). For CNV, 32 eyes (43.2%) had complete regression after the injection, 27 (36.5%) had partial regression, five (6.8%) had no response, and 10 eyes (13.5%) were not evaluated by the contributors. For NVD or NVE, seven eyes (63.6%) had complete regression of new vessels and four eyes (36.4%) had partial regression after the injection. CONCLUSIONS: Intravitreal bevacizumab led to short-term significant visual improvement and regression of inflammatory ocular neovascularization in a wide variety of inflammatory ocular diseases. 相似文献

PURPOSE: To investigate the efficacy and safety of intravitreal bevacizumab for managing choroidal neovascularization (CNV) due to age-related macular degeneration (AMD). DESIGN: Prospective interventional case series. METHODS: Seventeen eyes of 17 patients with subfoveal CNV due to AMD participated in this study at the American University of Beirut Ophthalmology Clinics. All patients had failed, refused, or were not eligible for photodynamic therapy. All eyes received a baseline eye examination, which included best-corrected visual acuity (BCVA), dilated fundus examination, ocular coherence tomography (OCT) imaging, and fluorescein angiography. An intravitreal injection of bevacizumab (2.5 mg/0.1 ml) was given at baseline and followed by two additional injections at four-week intervals. BCVA, OCT, and fluorescein angiography were repeated four weeks after each injection. Main outcome measures were improvement in BCVA and central retinal thickness (CRT). RESULTS: Mean baseline BCVA was 20/252 (median 20/200), and baseline CRT was 362 microm (median 350 microm). Improvement in VA and CRT occurred by the fourth week. At 12 weeks, mean BCVA was 20/76 (P < .001) and median BCVA was 20/50 (P < .001). Both mean and median CRT decreased to 211 microm (P < .001). Thirteen (76%) of 17 eyes had total resolution of subretinal fluid, and four eyes (24%) had BCVA better than 20/50. No systemic or ocular side effects were noted at any time. CONCLUSION: Eyes with CNV due to AMD treated with intravitreal bevacizumab had marked anatomic and visual improvement. Further studies are necessary to confirm the long-term efficacy and safety of this treatment. 相似文献

Abstract Purpose: To describe two cases of extrafoveal choroidal neovascularization (CNV) after ocular trauma successfully treated with intravitreal bevacizumab injection. Methods: A 41-year-old man presented for progressive visual impairment in the left eye (LE). The patient had a positive history for pseudoxanthoma elasticum and suffered a blunt trauma in the LE 1 year before. Best-corrected visual acuity (BCVA) in the affected eye was 20/100. Fundus examination of the LE revealed angioid streaks and a choroidal rupture with retinal hemorrhages. Fluorescein angiography (FA) revealed an extrafoveal CNV and optical coherence tomography (OCT) findings demonstrated the presence of intraretinal fluid extending to the fovea. The second patient was a 61-year-old man complaining of blurred vision in the LE. Fundus examination of the LE revealed retinal pigment epithelium (RPE) changes, while FA showed the presence of an extrafoveal CNV close to the area of RPE attenuation. Intraretinal fluid extending to the fovea was detectable on OCT examination. An intravitreal injection of bevacizumab was proposed in both cases. Results: In the first patient, treatment with one intravitreal bevacizumab injection was successful in contrasting CNV activity, as OCT findings showed a resolution of intraretinal fluid accumulation. BCVA remained unchanged (20/100) over the 12-month follow-up period, most probably due to permanent alteration of the photoreceptors. In the second case, BCVA improved from 20/40 to 20/20 with complete resolution of leakage on FA and fluid on OCT 1 month after a single intravitreal injection of bevacizumab. Visual function remained stable over the 14-month follow-up. Conclusions: Our results indicate that intravitreal bevacizumab is effective in the management of extrafoveal CNV secondary to ocular trauma. 相似文献

PURPOSE: To evaluate the safety and efficacy of intravitreal bevacizumab in the treatment of idiopathic choroidal neovascularization (CNV) and CNV secondary to central serous chorioretinopathy (CSC) or punctate inner choroidopathy (PIC). DESIGN: Prospective, nonrandomized, interventional case series. METHODS: In an institutional clinical practice, 15 patients were recruited; nine had idiopathic CNV, two had CNV secondary to CSC, and four had CNV attributable to PIC. Patients received three monthly 1.25-mg intravitreal bevacizumab injections for three months. Patients were followed for six months, and the best-corrected visual acuity (BCVA), fluorescein angiography (FA) findings, and optical coherence tomography (OCT) central foveal thickness (CFT) were assessed. RESULTS: At baseline, the mean logMAR BCVA was 0.48 (Snellen equivalent = 20/60). The mean logMAR BCVA improved significantly to 0.25 (Snellen equivalent = 20/36) and 0.17 (Snellen equivalent = 20/30) at one and six months, respectively (both P = .001). The mean OCT CFT reduced from 306 microm at baseline to 201 microm at six months (P < .001). All eyes (100%) had visual improvement of 1 line or more at six months, and 11 (73.3%) improved by 2 or more lines. FA showed absence of CNV leakage, the angiographic end point, at three months, and no recurrence was observed at six months in all eyes. No systemic or ocular adverse events were encountered. CONCLUSIONS: Intravitreal bevacizumab injections resulted in visual and anatomic improvements in eyes with idiopathic CNV and CNV attributable to CSC or PIC. Further studies are warranted to assess the long-term safety and the regimen for optimal efficacy of intravitreal bevacizumab. 相似文献

Intravitreal bevacizumab for previously treated choroidal neovascularization from age-related macular degeneration 总被引:2,自引:0,他引:2
PURPOSE: To report the optical coherence tomography (OCT) findings and visual results in a series of patients treated with intravitreal bevacizumab for choroidal neovascularization (CNV) associated with age-related macular degeneration (AMD), and to determine if a difference in treatment effect exists between previously treated and treatment na?ve patients. METHODS: A retrospective review of all patients treated with intravitreal bevacizumab for CNV from AMD with visual acuity greater than or equal to 20/320 between September 2005 and February 2006 was performed. OCT data recorded included central macular thickness and the presence or absence of cystic intraretinal fluid, subretinal fluid, or pigment epithelial detachment at the time of the initial injection, at 1-week, 1-month, and 3-month intervals, as well as at the end of follow-up. Visual acuity measurements were recorded using Early Treatment Diabetic Retinopathy Study charts. Any ocular or systemic adverse events were recorded. Statistical analysis was performed to determine if OCT and visual acuity results were significant and to determine if a difference in outcomes existed between previously treated patients and treatment na?ve patients. RESULTS: Fifty-four eyes of 51 patients treated with intravitreal bevacizumab for CNV from AMD were identified. A total of 178 injections were performed. Mean number of days of follow-up was 138 with 91% of patients having at least 90 days of follow-up. Seventy percent of patients had undergone previous treatment for CNV. The mean number of intravitreal bevacizumab injections per eye was 3.3. Combined treatment with photodynamic therapy was provided in 20% of cases at the initial intravitreal injection. OCT data for all patients revealed an initial mean thickness of 362 mum, which was decreased at 1 week to 278 microm (P = 0.001), 235 microm at 1 month (P < 0.0001), 238 microm at 3 months (P = 0.0004), and 244 microm for the end of follow-up (P < 0.0001). Cystic retinal edema, subretinal fluid, and pigment epithelial detachment resolved in the majority of cases, but pigment epithelial detachment frequently took longer to resolve. Initial mean visual acuity was 20/125 (logMAR 0.8), and final mean visual acuity was 20/100 (logMAR 0.7) (P = 0.03). There was no difference in OCT or visual acuity outcomes (P = 0.62 and P = 0.28, respectively) between previously treated and treatment na?ve patients. There was no difference in OCT or visual acuity outcomes (P = 0.67 and P = 0.21, respectively) between patients who received combination therapy and those who received monotherapy with intravitreal bevacizumab. No systemic or ocular adverse events were recorded. CONCLUSION: Intravitreal bevacizumab for CNV from AMD results in a rapid decrease in OCT-measured retinal thickness in a majority of cases. Visual acuity also improved in this series, suggesting a potential corresponding visual benefit. This series suggests that previously treated and treatment na?ve patients have similar outcomes. 相似文献

AIM: To evaluate the predictors of visual improvement in eyes with naive choroidal neovascularization secondary to age-related macular degeneration (CNV -AMD) treated with intravitreal bevacizumab (IVB) monotherapy.METHODS: Fifty eyes with naive CNV- AMD with pretreatment best-corrected visual acuity (BCVA) better than 20/200 and treated with IVB monotherapy were evaluated. Several variables including age, sex, pre-treatment BCVA, CNV type and lesion size on fluorescein angiogram as well as SD-OCT parameters including pre-treatment central macular thickness (CMT), inner-segment/outer-segment (IS/OS) junction integrity, and external limiting membrane (ELM) integrity were analyzed to predict visual outcome.RESULTS:On univariate regression, pretreatment ELM damage was associated with less visual improvement after treatment (P=0.0145). However, ELM damage predicted only 10% of the visual outcome. On multivariate regression, pretreatment BCVA, IS/OS junction, and ELM integrity on SD-OCT were the significant predictors for the treatment effect and together predicted 37% of visual improvement.CONCLUSION: Pretreatment BCVA, ELM and IS/OS junction integrity on SD-OCT are of significant value in predicting the visual improvement in naive wet AMD patients treated with IVB monotherapy. 相似文献

Purpose
To investigate the short-term effects of panretinal photocoagulation (PRP) combined with an intravitreal injection of Avastin® (bevacizumab) as an adjuvant to high-risk proliferative diabetic retinopathy (PDR).Methods
The data was collected retrospectively from the eyes of high-risk PDR patients, which were divided into two groups. One eye was treated with only PRP (PRP only group) and the fellow eye of same patient was treated with both PRP and intravitreal bevacizumab injection (Adjuvant group). Best corrected visual acuity (BCVA), IOP (intraocular pressure), and new vessel (NV) size in fluorescein angiography were recorded immediately and at the six-week follow-up visit. Adverse events associated with intravitreal injection were investigated.Results
Of 12 patients with high-risk PDR, five were male and seven were female. There were no statistically significant BCVA or IOP changes after treatment in either group (p=0.916, 0.888). The reduction of NV size was found in both groups, but NV size in the adjuvant group showed a greater decrease than that of the PRP only group (p=0.038). Three patients had adverse events after intravitreal injection. Two patients had mild anterior uveitis and one patient had a serious complication of branched retinal artery obstruction (BRAO).Conclusions
Intravitreal bevacizumab injection with PRP resulted in marked regression of neovascularization compared with PRP alone. One serious side effect, BRAO, was noted in this study. Further studies are needed to determine the effect of repeated intravitreal bevacizumab injections and the proper number of bevacizumab injections as an adjuvant. 相似文献20.
