Retinal pigment epithelial tear after intravitreal bevacizumab injection

PURPOSE: To report two cases of a retinal pigment epithelial (RPE) tear after intravitreal bevacizumab injection for exudative age-related macular degeneration (AMD). DESIGN: Observational case series. METHODS: Two patients presented with occult choroidal neovascularization secondary to AMD. Both patients received intravitreal bevacizumab injections. RESULTS: The first patient developed a RPE tear shortly after a third intravitreal bevacizumab injection. The second patient developed a RPE tear 10 days after a second intravitreal bevacizumab injection. CONCLUSIONS: Although RPE tears may occur spontaneously as part of the natural history of exudative AMD, patients may develop visually devastating RPE tears after repeat intravitreal bevacizumab injection. Further studies are needed to determine the incidence of RPE tears after intravitreal bevacizumab injections.     

Retinal pigment epithelium tears after intravitreal injection of bevacizumab (avastin) for neovascular age-related macular degeneration

BACKGROUND: Intravitreal bevacizumab (Avastin, Genentech, Inc., South San Francisco, CA) treatment of neovascular age-related macular degeneration (AMD) has become an important part of clinical retinal practice. We describe retinal pigment epithelium (RPE) tears that were noted after intravitreal injection of bevacizumab. METHODS: In this multimember, retrospective case series, data on eyes that developed RPE tears after intravitreal bevacizumab injection were collected and analyzed. Previous treatments, type of lesion, time to tear, and preinjection and final visual acuities were all compared. The total numbers of bevacizumab injections were available from all four institutions and compiled to estimate the incidence rate. RESULTS: Four retina centers administered a total of 1,455 intravitreal 1.25-mg bevacizumab injections for neovascular AMD during the 9-month study period. Twelve patients presented with RPE tears within 4 days to 8 weeks of injection (mean +/- SD, 24.3 +/- 15.2 days from injection to tear). In each case, the RPE tear was preceded by an RPE detachment, and all had a component of serous sub-RPE fluid. On the basis of our collective data, we estimate an incidence rate of approximately 0.8%. CONCLUSIONS: RPE tears can occur after intravitreal injection of bevacizumab. The low incidence of this adverse event should not preclude anti-vascular endothelial growth factor therapy counseling for patients with neovascular AMD, but eyes with serous RPE detachments appear to be most vulnerable to this adverse event.     

Retinal pigment epithelial tears after intravitreal bevacizumab injection for neovascular age-related macular degeneration

PURPOSE: To study retinal pigment epithelium (RPE) tears after off-label intravitreal bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA) injection for neovascular age-related macular degeneration. Eyes with a vascularized pigment epithelial detachment (PED) that developed an RPE tear were compared with eyes with a vascularized PED but without an RPE tear. METHODS: Nine retina specialists across the United States and in Europe participated in this retrospective case series. All eyes that received intravitreal bevacizumab injection for choroidal neovascularization (CNV) over 12 months (October 2005 to September 2006) were included. Eyes without all three confirmed tests (fluorescein angiography, fundus photography, and optical coherence tomography) were excluded from analysis. Statistical analyses were performed on multiple characteristics of eyes with a vascularized PED that did and did not develop an RPE tear. RESULTS: Among 2,785 intravitreal bevacizumab injections for 1,064 eyes, RPE tears were found in 22 eyes in 22 patients (2.2%). A vascularized PED was present in 21 of 22 eyes that developed an RPE tear (17.1% of PED eyes; 15, 100% occult CNV; 6, predominantly occult CNV). Mean interval from bevacizumab injections to RPE tears was 37.3 days. Mean follow-up time was 124.9 days. Mean subfoveal PED size was larger for eyes with tears than for those without tears (13.97 mm vs 9.9 mm, respectively; P = 0.01; odds ratio, 1.09). There was substantially smaller mean ratio of CNV size to PED size for eyes with tears than for those without tears (27.9% vs 67.6%, respectively; P = 0.005). Mean pre-bevacizumab injection best-corrected Snellen visual acuity was 20/162, and mean post-RPE tear best-corrected visual acuity was 20/160 (P = 0.48). CONCLUSION: Large PED size is a predictor for RPE tears, and a small ratio of CNV size to PED size (<50%) is more common in eyes with RPE tears. Vision may be preserved despite RPE tears.     

Retinal pigment epithelial tears after single administration of intravitreal bevacizumab for neovascular age-related macular degeneration

PURPOSE: To analyse retinal pigment epithelial (RPE) tears following single administration of intravitreal bevacizumab for neovascular age-related macular degeneration (AMD) during early follow-up. METHODS: Interventional, retrospective, non-comparative case series included 397 patients (409 eyes) of the 746 consecutive patients that met the eligibility criteria. Standardized visual acuity testing, fluorescein angiography, and optical coherence tomography were performed. Data collected included status of the fellow eye, previous treatment, subtypes of choroidal neovascularization (CNV), size and composition of the lesion. Multiple linear regression modelling was used to explore the effect of baseline parameters on the RPE tears. Primary end point was occurrence of RPE tears within 6 weeks after therapy. RESULTS: Fifteen of the 409 eyes (3.6%) developed RPE tear (95% confidence interval: 2.2-6.0, odds ratio: 26.3). The statistical modelling showed significant association between RPE tear and occult without classic CNV/predominantly haemorrhage vspredominantly/minimal classic CNV (P=0.019), as well as medium or large (>4 disc area) vssmall size of the total lesion (P=0.038). Previous treatment and status of the fellow eye did not statistically influence the risk of RPE tears. CONCLUSIONS: An RPE tear can develop in up to 3.6% of eyes with neovascular AMD following single administration of intravitreal bevacizumab in a short-term follow-up. Medium and large lesion size and occult without classic and predominantly haemorrhagic subtype of CNV were important predictive factors. Preoperative assessment of the lesion characteristics may help in identifying the risk of individual patients with neovascular AMD before intravitreal bevacizumab treatment.     

Retinal pigment epithelial tears after intravitreal bevacizumab injection for predominantly classic choroidal neovascularization

PURPOSE: To detect retinal pigment epithelium (RPE) tears in predominantly classic choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) treated with intravitreal bevacizumab injections. METHODS: Forty consecutive patients with predominantly classic CNV secondary to AMD were treated with 1.25 mg of intravitreal bevacizumab. Patients were evaluated with visual acuity (VA) measured with Early Treatment Diabetic Retinopathy Study charts, optical coherence tomography, and fluorescein angiography. RESULTS: Three patients developed a RPE tear after the first injection. The first patient had been treated with verteporfin therapy and VA remained unchanged. In the other two cases the CNV was naive and VA improved since the foveal center was not involved by the tear and macular edema was reduced. CONCLUSIONS: RPE tears can occur following intravitreal bevacizumab injections in patients with predominantly classic CNV although VA is not always affected.     

Retinal pigment epithelium tear after intravitreal bevacizumab for exudative age-related macular degeneration

PURPOSE: To report on the development of retinal pigment epithelium tears after intravitreal injections of bevacizumab as treatment of exudative age-related macular degeneration (AMD). DESIGN: Interventional case series. METHODS: The study included 63 patients who received an intravitreal injection of 1.5 mg bevacizumab as treatment of a detachment of the retinal pigment epithelium attributable to AMD and who had a follow-up of at least two months. RESULTS: Four patients (6%) developed a tear of the retinal pigment epithelium in the parafoveal region. Compared with the baseline value, visual acuity at the end of follow-up remained stable in three patients and declined in the fourth patient. CONCLUSIONS: Intravitreal injections of bevacizumab may be followed by a tear of the retinal pigment epithelium in eyes with exudative AMD and a retinal pigment epithelium detachment.     

Visual acuity change after intravitreal bevacizumab for exudative age-related macular degeneration in relation to subfoveal membrane type

PURPOSE: To examine an association between the subfoveal neovascular membrane type and visual acuity change after intravitreal bevacizumab injection for exudative age-related macular degeneration (AMD). METHODS: We carried out a clinical, retrospective, interventional case-series study including 66 consecutive patients (67 eyes) with exudative AMD who received an intravitreal injection of 1.5 mg bevacizumab. Study subgroups included the occult type without or with minimally classic subfoveal neovascularization (n = 28 eyes, 42%), predominantly or purely classic subfoveal neovascularization (n = 22 eyes, 33%), and eyes with retinal pigment epithelium detachment (n = 17 eyes, 25%). Follow-up was >or= 2 months. RESULTS: The maximal visual acuity (VA) gain (mean +/- standard deviation - 0.07 +/- 0.30 logMAR, 0.5 +/- 2.9 Snellen lines; p = 0.87), and VA gain at 1 month (p = 0.10), 2 months (p = 0.77) and 3 months (p = 0.35) after the injection did not vary significantly between the three study subgroups. Correspondingly, a multivariate analysis did not reveal a statistically significant (p = 0.57) influence of subfoveal lesion type on gain in VA. CONCLUSIONS: Visual improvement after intravitreal bevacizumab does not differ markedly between various types of subfoveal neovascularization in AMD.     

Retinal pigment epithelium tears following intravitreal ranibizumab therapy

Two patients with choroidal neovascularization secondary to age-related macular degeneration (AMD) developed a retinal pigment epithelial (RPE) tear following intravitreal injection of ranibizumab. One patient developed the RPE tear within 2 weeks of the injection, the other within 6 weeks of a second injection. Both patients presented with vision loss of one line at diagnosis of the RPE tear. During long-term follow-up, visual acuity improved in one patient by one line and deteriorated in the second patient by three lines. RPE tears may occur after intravitreal injection of ranibizumab in patients with neovascular AMD, probably because of the rapid regression of the fibrovascular membrane.     

Retinal pigment epithelial tear after ranibizumab therapy for subfoveal fibrovascular pigment epithelial detachment

PURPOSE: To describe the unusual complication of retinal pigment epithelial (RPE) tear after intravitreal ranibizumab (Lucentis) for subfoveal fibrovascular pigment epithelial detachment (PED) and its effective management. METHODS: Chart review for case report of RPE tear after ranibizumab. RESULTS: An inferior RPE tear was documented by fluorescein angiography, fundus photography, and optical coherence tomography (OCT) 1 month after receiving repeat ranibizumab injection in the right eye of a patient with bilateral subfoveal fibrovascular PED. He had undergone multiple bevacizumab followed by ranibizumab injections for neovascular age-related macular degeneration (AMD) in both eyes, starting 6 months previously. Subsequent antivascular endothelial growth factor (VEGF) therapy improved vision of right eye from 20/200 to 20/40, despite RPE tear. CONCLUSIONS: RPE tear may form after anti-VEGF therapy, including ranibizumab injection. Further anti-VEGF therapy may preserve or improve vision. To the authors' knowledge, this is first case report of effective suppression of neovascular activity with bevacizumab after an RPE tear following ranibizumab therapy.     

Retinal pigment epithelial tear after intravitreal ranibizumab for subfoveal CNV secondary to AMD

Purpose To report a case of retinal pigment epithelial tear following intravitreal ranibizumab injection for subfoveal choroidal neovascularization. Methods Retrospective single case review. Results A 78-year-old Caucasian female was treated with intravitreal ranibizumab for occult subfoveal choroidal neovascularization (CNV) from age-related macular degeneration (AMD). She returned for evaluation with decreased vision and was found to have a retinal pigment epithelial tear on biomicroscopy. Fluorescein angiography and OCT testing confirmed the clinical findings. Conclusion Although a pigment epithelial tear in neovascular AMD can represent natural history, prior reports of such tears after thermal laser, photodynamic therapy with verteporfin and following intravitreal injection of pegaptanib Na combined with this case report suggest that clinicians should be aware of and monitor patients for the possibility of this complication after intravitreal injections of ranibizumab.     

Long-term visual outcome of pigment epithelial tears in association with anti-VEGF therapy of pigment epithelial detachment in AMD

Purpose

Retinal pigment epithelium (RPE) tears may develop as a complication after anti-VEGF (vascular endothelial growth factor) treatment for pigment epithelial detachments (PEDs) in exudative age-related macular degeneration (AMD). This retrospective study analyses best-corrected visual acuity (BCVA) and foveal involvement after RPE tears that are associated with anti-VEGF therapy due to PED in exudative AMD.

Methods

A total of 37 patients with RPE tears during anti-VEGF therapy (bevacizumab 12, ranibizumab 21 and pegaptanib 4 eyes) for progressive PED in AMD (PED with occult choroidal neovascularization 25 eyes and PED with retinal angiomatous proliferation 12 eyes) were included in this study. We analyzed BCVA and different morphologic aspects by means of appearance on fluorescein angiography and optical coherence tomography. Mean follow-up was 88 weeks.

Results

RPE tears were diagnosed a mean of 56 days after the first injection. BCVA deteriorated after RPE tear and during follow-up significantly (P<0.001), with 53.2% of eyes being legally blind (WHO, world health organization) at 12 months. RPE-free foveal area, foveal wrinkling of the RPE, and fibrotic scar development were significantly associated with worse visual acuity.

Discussion

RPE tears can be observed in 12–15% of treated eyes during anti-VEGF therapy for PED in exudative AMD. Owing to the close time relationship with the therapy, this complication must be taken into consideration. Visual prognosis is associated with a decrease in vision in the long term, often resulting in a severe visual disability. Relevant factors for a negative visual prognosis were the potential foveal involvement of the central RPE and morphologic fibrovascular transformation of the RPE tear.     

Retinal pigment epithelium tears after intravitreal injection of ranibizumab for predominantly classic neovascular membranes secondary to age‐related macular degeneration

Acta Ophthalmol. 2010: 88: 736–741

Abstract.

Purpose: Retinal pigment epithelium (RPE) tear is an extremely rare complication in patients with classic neovascular membranes without RPE detachment. We evaluate their incidence and functional outcome following treatment with intravitreal ranibizumab. Methods: Observational study of 72 consecutive patients (74 eyes) treated at Jules Gonin University Eye Hospital, Lausanne, with intravitreal ranibizumab 0.5 mg for classic choroidal neovascularization (CNV) between March 2006 and February 2008. Best‐corrected visual acuity (BCVA), fundus examination and optical coherence tomography were recorded monthly; fluorescein angiography was performed at baseline and repeated at least every 3 months. Results: RPE tears occurred in four (5.4%) eyes temporal to the fovea, after a mean of four injections (range 3–6). Mean baseline BCVA was 0.25 decimal equivalent (logMAR 0.67) and improved despite the RPE tear to 0.6 decimal equivalent (logMAR 0.22). Conclusion: RPE tears following intravitreal ranibizumab injections for classic CNV can occur in about 5% of patients, even in the absence of baseline RPE detachment. Nevertheless, vision may improve provided the fovea is not involved.     

Intravitreal bevacizumab (Avastin) treatment of neovascular age-related macular degeneration

PURPOSE: To report the change in visual acuity and central retinal thickness by optical coherence tomography (OCT) after intravitreal injections of bevacizumab for the treatment of neovascular age-related macular degeneration (AMD). METHODS: A retrospective case series in a university-based practice evaluated patients with subfoveal choroidal neovascularization (CNV) due to AMD. Patients received intravitreal injections (1.25 mg) of bevacizumab and were monitored monthly with determination of best-corrected ETDRS visual acuity and OCT for persistence of retinal thickening. Eyes were retreated on an "as needed" basis, defined by presence of intraretinal or subretinal fluid. Patients were monitored every 2 months to 3 months for persistence of angiographic leakage. RESULTS: Seventy-nine eyes of 74 consecutive patients received the initial injection of bevacizumab between August 1, 2005, and January 30, 2006. Sixty-eight eyes (86%) of 64 patients had at least 3 months of follow-up. Mean central retinal thickness +/- SD decreased from 304 +/- 83 microm at baseline to 237 +/- 105 microm at 3 months (P = 0.00002). Mean ETDRS visual acuity gained 4 letters from 20/100 at baseline to 20/80-1 at 3 months (P = 0.040). Twenty eyes (25%) appeared to have a sustained response to a single injection and did not require further injections through 3 months. Two patients had a potentially drug-related adverse event (ischemic stroke and myocardial infarction). No serious injection-related adverse events occurred. CONCLUSIONS: Intravitreal bevacizumab injection affects a rapid decrease in retinal thickness to normal or near-normal levels and improvement in visual acuity in eyes with CNV due to AMD. The sustainability of changes in retinal thickness and visual acuity in response to bevacizumab treatment warrant further investigation and long-term follow-up.     

Treatment of neovascular age-related macular degeneration with intravitreal bevacizumab: efficacy of three consecutive monthly injections

PURPOSE: To report the efficacy of treatment of neovascular age-related macular degeneration (AMD) with intravitreal bevacizumab (Avastin; Genentech, Inc, South San Francisco, California, USA) when administered in a series of three monthly injections followed by a period of observation. DESIGN: Retrospective case series. METHODS: Retrospective review of consecutive eyes with all choroidal neovascular lesion subtypes resulting from neovascular AMD treated with intravitreal bevacizumab. Treatment consisted of a pars plana injection of 1.25 mg Avastin (0.05 ml bevacizumab at a concentration of 25 mg/ml). Evaluation consisted of a complete ophthalmologic examination, including best-corrected visual acuity (VA) measurement, ophthalmoscopy, and optical coherence tomography. Eyes received a series of three monthly injections followed by a three-month period of observation. RESULTS: A total of 36 patients (37 eyes) received a series of three consecutive monthly intravitreal injections of bevacizumab. Twenty (54%) of 37 eyes had no previous treatments for neovascular AMD in the eye that received bevacizumab. Seventeen (46%) of 37 eyes had received some previous treatment before initiation of bevacizumab therapy. Intravitreal Avastin therapy produced an improvement in foveal thickness over time in eyes with neovascular AMD. This improvement was sustained during the series of three monthly injections. All eyes experienced worsening after three months without treatment. No statistically significant effect on VA was demonstrated in this series. CONCLUSION: Intravitreal bevacizumab therapy produced an improvement in foveal thickness over time in eyes with neovascular AMD when one injection was given each month for three consecutive months. All eyes experienced increased foveal thickening during the subsequent three months without treatment.     

Spectral domain optical coherence tomography features of multiple subfoveal retinal pigment epithelial tears after intravitreal bevacizumab

Retinal pigment epithelial (RPE) tear has been described to occur spontaneously, after laser photocoagulation and in recent times, after intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents. In the latter case, the rapid contraction of the choroidal vascular membrane underneath a serous RPE detachment is believed to be the underlying cause. Preservation of good visual acuity after the occurrence of RPE tear with continued use of intravitreal VEGF agents has been reported. In this case report, we describe the occurrence of multiple RPE tears with the use of intravitreal bevacizumab and also correlate the preservation of visual acuity with features seen on spectral domain optical coherence tomography.     

Spontaneous or secondary to intravitreal injections of anti-angiogenic agents retinal pigment epithelial tears in age-related macular degeneration

AIM:To evaluate the visual function evolution of retinal pigment epithelial (RPE) tears in patients with age-related macular degeneration (AMD) according to type of occurrence [spontaneous or secondary to anti-vascular endothelial growth factor (anti-VEGF) injection] and the topographic location of the tear after a two-year follow-up period.METHODS:A total of 15 eyes of 14 patients with RPE tears in exudative AMD were analyzed retrospectively at the University Eye Clinic of Trieste. Inclusion criteria were:patient age of 50 or older with AMD and RPE tears both spontaneous occurring or post anti-VEGF treatment. Screening included:careful medical history, complete ophthalmological examination, fluorescein angiography (FA), indocyanine green angiography (ICG), autofluorescence and infrared imaging and optical coherence tomography (OCT). Patients were evaluated every month for visual acuity (VA), fundus examination and OCT. Other data reported were:presence of PED, number of injections before the tear, location of the lesion.RESULTS: Mean follow-up was 24wk (SD±4wk). A total of 15 eyes were studied for RPE tear. In 6 cases (40%), the RPE tears occurred within two years of anti-VEGF injections the others occurred spontaneously. In 13 cases (86.6%), the RPE tear was associated with pigment epithelial detachment (PED). In 7 cases (46.6%), the RPE tear occurred in the central area of the retina and involved the fovea. Two lesions were found in the parafoveal region, six in the extra-macular area. In all cases visual acuity decreased at the end of the follow-up period (P<0.01) independently of the type or the topographical location of the lesion.CONCLUSION:RPE tear occurs in exudative AMD as a spontaneous complication or in relation to anti-VEGF injections. Visual acuity decreased significantly and gradually in the follow-up period in all cases. No correlation was found between visual loss and the type of onset or the topographic location of the tears.     

Bevacizumab and Neovascular Age Related Macular Degeneration: Pathogenesis and Treatment

The pathogenesis of neovascular age related macular degeneration (AMD) is multifactorial including inflammation and angiogenesis leading to choroidal neovascularization (CNV). Therapy against vascular endothelial growth factor (VEGF) has revolutionized the treatment of neovascular AMD. Intravitreal off-label use of bevacizumab proved to be safe. This literature review was conducted to study improvement in visual acuity, change in central retinal thickness (CRT), safety, pharmacodynamics, and possible resistance to intravitreal bevacizumab over a one-year period in eyes with neovascular AMD. We reviewed articles between 1997 and January 2010 that included at least 30 patients with AMD who received intravitreal bevacizumab monotherapy for at least 1 year. The mean number of letters gained, decrease in CRT, and number of injections were 8 letters, 125.3?µm, and 4.3 injections, respectively. Further, randomized prospective clinical trials are needed to determine the efficacy and safety of intravitreal bevacizumab in the treatment of neovascular AMD.     

Intravitreale Anti-VEGF-Therapie mit Bevacizumab bei neovaskulärer AMD

PURPOSE: To report on the efficacy of intravitreal bevacizumab as off-label therapy in different angiographic subtypes in neovascular age-related macular degeneration (AMD). METHODS: Seventy-five patients with neovascular AMD and recent disease progression were classified into different angiographic subtypes and were treated with intravitreal bevacizumab (1.25 mg/0.05 ml) at 6-week intervals. Patients with subfoveal classic choroidal neovascularization (CNV) also received photodynamic therapy. ETDRS visual acuity, ophthalmic exams, and optic coherence tomography (OCT) were performed before treatment, 1 week after treatment, and then on a 6-week basis. Fluorescein angiographies and medical check-ups were also done. RESULTS: Bevacizumab led to stabilization of visual acuity (loss of less than 15 letters) in all angiographic subtypes during a follow-up of 37+/-13 weeks. Patients with occult extrafoveal CNV (n=6) profited the most and gained 2+/-2 lines. Treatment with intravitreal bevacizumab was very well tolerated in all patients, with neither systemic nor intraocular side effects, with the exception of one retinal pigment epithelium tear. CONCLUSION: Intravitreal bevacizumab treatment is efficacious in all angiographic CNV subtypes and leads to reduction of macular edema and stabilization or improvement in visual acuity.

Retinal pigment epithelium tears after intravitreal bevacizumab in pigment epithelium detachment

PURPOSE: To evaluate pigment epithelium detachment (PED) secondary to exudative age-related macular degeneration (AMD) treated with intravitreal injection of bevacizumab with regard to incidence of retinal pigment epithelium tears (RIPs). DESIGN: Retrospective, interventional case series. METHODS: Institutional study of 31 eyes with PED in exudative AMD receiving intravitreal bevacizumab. Main outcome measures were Early Treatment of Diabetic Retinopathy Study (ETDRS) visual acuity, PED vascularization and size measured by angiography and optical coherence tomography (OCT) imaging, and incidence of RIP. RESULTS: Vision improved in six eyes and remained stable in 22 eyes (follow-up, 12.3 +/- 10.3 weeks). Twenty-eight eyes showed a vascularized PED. Four eyes (12.9%) experienced an RIP without vision loss. All RIP cases were vascularized in more than 50% of total lesion size. CONCLUSIONS: In short-term follow-up, the risk for RIP after bevacizumab injection in eyes with PED seems to be moderately, but not statistically significantly, increased in PED lesions vascularized more than 50%.
