Purpose
To find models that will explain the variability in postoperative visual acuity (VA) (logarithmic: logMAR) associated with unilateral primary rhegmatogenous retinal detachment (RD).Methods
This was a prospective clinical cohort study of 33 patients with proliferative vitreoretinopathy (PVR: PVR<C3) and 33 without PVR, all of whom were candidates for scleral buckling (SB) surgery. Central retinal artery (CRA) Doppler sonography parameters (peak systolic, end diastolic velocities and resistibility index) and intraocular pressure (IOP) were measured before SB. Immunoreactive endothelin-1 (IR-ET-1) levels in both plasma and subretinal fluid (SRF) were measured using a radioimmunoassay. Visual outcomes were analysed by stepwise multivariate linear regression. The preoperative parameters used in the analysis included RD duration, IOP, logMAR VA, CRA parameters, preoperative plasma levels and intraoperative levels of IR-ET-1 in the SRF.Results
The models for 8-month-postoperative logMAR VA demonstrated a predictive power higher than 85%. The values of the 8-month-postoperative logMAR VA were as follows: (a) in No PVR= −0.151+0.06 preoperative duration (days), with a predictive power of 85.3% (b) in PVR= −1.071+0.06 SRF IR-ET-1 (pg/ml)+0.459 preoperative logMAR VA explaining 89.9% of the variability in the postoperative logMAR VA.Conclusions
The duration of RD and the levels of IR-ET-1 in the SRF appear to be the best explanatory variables in the models for 8-month-postoperative logMAR VA variability in RD patients. RD surgery should be performed as soon as possible to best preserve VA. 相似文献2.

PURPOSE: To analyze if endothelin-1 (ET-1) may have an effect on ophthalmic artery (OA) blood flow velocities and intraocular pressure (IOP) in retinal detachment (RD). METHODS: Using radioimmunoassay, immunoreactive (IR) ET-1 levels were tested in both plasma and subretinal fluid (SRF) specimens from patients with RD, while only plasma specimens from normal (healthy) subjects were tested. OA Doppler sonography parameters and IOP were measured in eyes with RD, with and without proliferative vitreoretinopathy (PVR), their respective healthy fellow eyes, and normal eyes. RESULTS: RD eyes had lower OA peak systolic velocity (PSV) and end diastolic velocity (EDV), higher resistivity index (RI), lower IOP, and higher plasma IR ET-1 levels than normal eyes (P < 0.0001). Eyes with PVR had lower OA PSV and EDV, higher RI, lower IOP, higher plasma IR ET-1 levels, and higher SRF IR ET-1 than eyes without PVR (P < 0.0001). A statistically significant linear correlation was found among OA parameters, IOP, and SRF IR ET-1 measurements. CONCLUSIONS: Decreased OA blood flow velocities may explain lower IOP found in RD patients, and ET-1 levels may be responsible for both measurements. 相似文献

AIM: To evaluate whether an achromatic interferometer, the Lotmar visometer, is useful in predicting postoperative visual outcome in patients with primary rhegmatogenous retinal detachment (RD) involving the macula. METHODS: This prospective study included 40 eyes of 40 non-consecutive patients with macula-off RD. The eyes were phakic or pseudophakic, had a clear optical media, and had a measurable potential vision on preoperative visometric examination. Preoperative variables included Snellen visual acuity, duration of macular detachment, extent of RD, and visometric potential acuity. Reattachment surgery consisted of radial scleral buckling in 33 patients, circumferential scleral buckling and encircling in seven patients, and subretinal fluid drainage in 10 patients. Retinal breaks were treated with cryotherapy or laser photocoagulation. Patients were followed up for at least 6 months after uncomplicated surgery. Best corrected visual acuity measured at any time during follow up was correlated with the preoperative variables. RESULTS: Preoperative visual acuity was less than 20/200 in 37 (93%) of 40 patients. Potential visual acuity of 20/200 or better was measured using the Lotmar visometer in 37 patients (93%). Postoperative visual acuity was correlated significantly with duration of macular detachment (r=0.55; p<0.001), and extent of RD approached statistical significance (r=0.31; p=0.05). There was a higher correlation between postoperative visual acuity and the visometric measurements (r=0.61; p<0.001). CONCLUSIONS: The Lotmar visometer may be a valuable method to estimate visual outcome after uncomplicated scleral buckling surgery in patients with RD involving the macula. 相似文献

Predictive visual outcome after macula-off retinal detachment surgery using optical coherence tomography 总被引:2,自引:0,他引:2
PURPOSE: To determine whether preoperative optical coherence tomography (OCT) is useful in predicting postoperative visual outcome for patients with primary macula-off rhegmatogenous retinal detachment (RD). METHODS: This prospective study included 20 nonconsecutive eyes with macula-off RD and successful reattachment of the retina. Preoperative 5-mm OCT was performed through the center of the fovea. The relationship among preoperative OCT findings, main preoperative clinical variables, and final postoperative visual acuity was statistically analyzed. RESULTS: Final postoperative visual acuity was negatively correlated with three preoperative OCT variables: height of RD at the central fovea (r=0.79; P <0.001), distance from the central fovea to the nearest undetached retina (r=0.75; P <0.00051), and, to a lesser degree, extent of structural changes in the detached retina (r=0.48; P=0.03). Preoperative visual acuity was the only clinical variable statistically correlated with final postoperative visual acuity in this study (r=0.55; P=0.01). Using multivariate logistic regression analyses, the structure of the detached retina combined with the distance from the central fovea to the nearest undetached retina, as determined with OCT, was highly correlated with final postoperative visual acuity (r=0.82; P <0.000051). CONCLUSION: Preoperative macular analysis with OCT may help to predict visual outcome for patients with macula-off RD. 相似文献

Comparative study of incomplete posterior vitreous detachment as a risk factor for proliferative vitreoretinopathy 总被引:10,自引:0,他引:10

· Background: Abnormal vitreoretinal relationships have recently been implicated in many vitreoretinal disorders. Sites of
abnormal vitreoretinal adherences are likely to exist in eyes predisposed to rhegmatogenous retinal detachment (RD), causing
either retinal tears or incomplete posterior vitreous detachment (PVD). The present study was designed in two parts to identify
the risk for preoperative and postoperative proliferative vitreoretinopathy (PVR) due to incomplete PVD. · Methods: We prospectively
evaluated the vitreoretinal relationships using high-resolution kinetic echography in 102 consecutive eyes of 100 patients
with rhegmatogenous RD. In the first part, a case-control study was conducted to compare the vitreous status in patients with
preoperative PVR (cases) with that in patients with non-PVR-complicated RD (controls). During the second part, patients with
noncomplicated RD (65 eyes) who were operated on by a simple retinal attachment procedure were followed up for a mean period
of 6.6 months to compare the recurrence of RD due to postoperative PVR according to their vitreous status. · Results: Patients
with PVR on study entry had a higher prevalence of partial PVD (28 of 32 eyes, 87%) than did controls (25 of 70 eyes, 35%).
The statistical significance of this difference was independent of all other variables studied. After a mean follow-up period
of 6.6 months, the incidence of recurrence of RD associated with postoperative PVR was 33% in the eyes with incomplete PVD,
compared with 4.9% in the eyes without incomplete PVD. · Conclusions: Our results support the notion that the occurrence of
incomplete PVD in RD is a significant risk factor for preoperative and postoperative PVR.

Background
To evaluate stereopsis after successful surgery for unilateral rhegmatogenous retinal detachment (RD), and to investigate the relationship between stereopsis and clinical factors.Methods
In 75 patients after RD surgery and 28 age-matched normal subjects, stereopsis was measured using the Titmus Stereo Test (TST) and TNO stereotest. Clinical data were collected, including age, gender, circumferential dimension of retinal tears, area and duration of RD, macular status, surgical procedures, postoperative spherical equivalent, and logarithm of the minimum angle of resolution best-corrected visual acuity (logMAR BCVA), low-contrast visual acuity, postoperative lens status (phakia/pseudophakia), and presence of postoperative epiretinal membrane (ERM), to determine the factors related to stereopsis.Results
Stereopsis in patients after surgery was significantly worse than normal subjects (p?<?0.0001). Stereopsis in TST was significantly correlated with the area of RD (p?<?0.005), difference of postoperative spherical equivalent between two eyes (p?<?0.05), postoperative logMAR BCVA (p?<?0.005), difference of postoperative logMAR BCVA between two eyes (p?<?0.01), and low-contrast visual acuity (p?<?0.05). Stereopsis in TNO stereotest showed significant association with postoperative logMAR BCVA (p?<?0.05). Stereopsis in both stereotests were significantly worse in patients with macula-off RD than macula-on RD (p?<?0.005, p?<?0.01 respectively). No significant relationship was found between stereopsis and other factors. Multiple regression analysis revealed that macular status (on/off) had a significant correlation with both stereopsis in TST and TNO stereotest (p?=?0.028, p?=?0.019 respectively), whereas other clinical parameters were not relevant.Conclusions
Stereopsis is significantly deteriorated in patients after RD surgery than in normal subjects. Stereopsis was associated with the difference in refraction between two eyes, postoperative visual acuity and contrast sensitivity, and preoperative macular status. 相似文献9.
PURPOSE: Foveal detachment after apparently successful retinal reattachment surgery for macula-on retinal detachments (RDs) has been previously documented. This pilot study aimed to utilize ocular coherence tomography (OCT) imaging to investigate foveal architecture after routine retinal detachment surgery and correlate this to visual acuity. METHODS: Prospective recruitment of patients attending one unit with macula-on RDs. Patients underwent full clinical examination including OCT preoperatively and RD surgery undertaken by scleral buckling, external drainage and air injection. Postoperatively patients had clinical examinations and OCT at 1 week, 1, 3, 6, and 12 months. RESULTS: A total of 12 consecutive patients were recruited into the study. All had macula-on RDs and normal OCTs at onset. There were no operative or postoperative complications. Retinal reattachment was achieved in all cases within 24 h postoperatively. At 1 month six of 12 patients (50%) showed foveal detachment on OCT, which was invisible on clinical examination. At 3 months, the foveal detachment persisted in four (33%) of these patients. In these cases the foveal detachment persisted at 6 months follow-up, however, a reduction in subfoveal fluid was noted. All cases had foveal reattachment by 12 months postoperatively. Visual acuity was closely correlated to the presence of foveal attachment. DISCUSSION: A high proportion of patients with successful retinal reattachment surgery had foveal detachments postoperatively. This phenomenon was associated with reduced visual acuity. The aetiology of this occurrence is unknown and warrants further investigation as there is the potential of a long-term effect on vision. 相似文献

ObjectiveTo identify risk factors affecting visual outcomes in successfully re-attached macula-off rhegmatogenous retinal detachment (RD) surgery.DesignA prospective study, using online databases, of visual outcomes for 2074 macula-off retinal detachments that were successfully re-attached by vitrectomy and internal tamponade. The database included detailed retinal diagrams of each detachment.Main outcome measureThe probability of achieving a post-operative visual acuity (VA) of ≤0.30 LogMAR (Snellen 6/12 or better).ResultsMale patients accounted for 64.9% of the sample and the median age was 63 years old. The median pre-operative VA was counting fingers (LogMAR 1.98); this improved to 0.41 LogMAR post-operatively. A post-operative VA of ≤0.30 LogMAR was achieved for 1012 (48.8%) eyes and the factors affecting this were the patient age and gender, pre-operative VA, duration of central vision loss, PVR grade, lens status, total RD and the presence of any ocular co-pathology where the model area under the receiver operator curve was 71.6%.ConclusionsFrom the identified risk factors that decrease the probability of achieving a post-operative visual acuity of ≤0.30 LogMAR, the most important modifiable risk factor was the duration of central vision loss. Recent macula-off retinal detachments should be repaired within 72 h of the loss of central vision.Subject terms: Outcomes research, Retinal diseases 相似文献

Proliferative vitreoretinopathy (PVR) is the only cause of ultimate failure following retinal detachment surgery. This study aimed to review the rate of postoperative PVR in a series of 186 consecutive patients with primary rhegmatogenous retinal detachments. All 186 detachments were repaired with a scleral buckling procedure combined with cryotherapy. Drainage of subretinal fluid was done at the discretion of the surgeon. The mean follow-up was 12 months. In this series 152 (82%) of primary detachments were repaired succesfully with a single operation. Sixty-eight percent of patients regained 0.3 or better visual acuity, and 3% of patients were left with visual acuity of 1/60 or less. After two or more operations the retina was attached in 96% of the cases. In 12 (6%) eyes PVR was responsible for the initial surgical failure. In 4 cases PVR (grade B and limited C) was present prior to surgery. In 3 cases PVR developed within 2 days postoperatively, in 3 cases after 3–6 weeks and in another 2 cases after 8–l0 months. Eight out of 12 (66%) PVR patients had undergone cataract surgery. One PVR case had preoperative intraocular inflammation. An association between the duration of retinal detachment, or drainage of subretinal fluid and the development of PVR could not be demonstrated. In conclusion, the rate of postoperative PVR in primary rhegmatogenous retinal detachments was low. PVR preoperatively present and pseudophakia may be risk factors. 相似文献

Preretinal dispersion of stimulated RPE cells has been suggested as a possible cause of the development of proliferative vitreoretinopathy (PVR). Retinal detachment (RD) and retinal breaks are associated with an exposure of corresponding areas of retinal pigment epithelium (RPE) which has been mechanically stimulated by coagulation. In a prospective, controlled study of 141 patients between 20 and 75 years of age, PVR grades were determined before and RD surgery and within six months following it PVR grades were correlated with the extent of RD, size of breaks, and area of coagulation. The severity of the PVR correlated significantly with both the extent of RD as well as the total number of coagulation exposures. There was a tendency toward higher grades of PVR with larger retinal breaks. The results are compatible with the hypothesis that at least certain variations of PVR are caused by preretinal dispersion of stimulated RPE cells. 相似文献

PurposeTo evaluate the efficacy and complication profile of excimer laser trabeculostomy (ELT), an emerging laser-based trabecular minimally invasive glaucoma surgery (MIGS), combined with cataract surgery in routine clinical practice.Patients and methodsSingle-site, retrospective, interventional study. Preoperative and postoperative clinical data of patients with cataract and open-angle glaucoma (OAG) who underwent combined phacoemulsification and ELT were collected and analyzed at preoperative day, one week postoperatively, and after one, two, three, six, nine and 12 months. Main outcome measure was intraocular pressure (IOP). Qualified and complete success were defined as an IOP less than 21 mmHg and an IOP reduction ≥ 20% from preoperative medicated IOP with or without adjuvant medical treatment, respectively.ResultsThirty-four eyes of 29 patients were included; 29 eyes completed 1-year follow-up. The mean preoperative IOP under medications was 20.9 ± 2.6 mmHg (± standard deviation, SD) and decreased significantly at one year (16.3 ± 1.9; p < 0.0001). The mean number of IOP-lowering medications decreased from 1.7 ± 0.7 to 0.3 ± 0.8 (p < 0.0001) at the 12-month follow-up. At one year, 81% of eyes were medication free. Qualified and complete success was obtained in 62% and 58% of eyes, respectively. Two eyes had postoperative hyphema, three eyes had transient IOP spikes and one patient underwent a subsequent filtering surgery at three months.ConclusionCombining ELT with phacoemulsification in eyes with cataract and mild to moderate OAG significantly reduced IOP and medication use without meaningful complications after one-year follow-up in a real world clinical practice setting. 相似文献

Objective: To evaluate the efficacy and safety of high-density silicone oil (HDSO) as an internal retinal tamponade after vitrectomy for complicated retinal detachment.Design: Retrospective, non-randomized study.Participants: Forty-one eyes of 41 patients who were 5–73 years of age.Methods: Medical records of patients with retinal detachment (RD) complicated with inferior proliferative vitreoretinopathy (PVR) requiring internal tamponade with HDSO were reviewed. Eyes with retinal vascular diseases and inflammatory diseases were excluded from the study. Follow-up examinations were scheduled at 1 week and 1, 3, 6, and 12 months after the initial surgery.Results: Median value of follow-up was 8 months (range, 3–40 months). Twenty-five patients had rhegmatogenous RD with significant PVR and the remaining patients had complicated RD secondary to trauma. Preoperative visual acuity was 2.55 ± 0.75 logMAR, which became 1.89 ±0.91 at the last follow-up visit (p < 0.05). Complications included increased intraocular pressure (9.7%), hypotony (2.4%), cataract (57.1%), silicone oil in anterior chamber (17%), persistent total corneal edema (7.3%), band keratopathy (7.3%), and significant inflammation (2.4%). Intraretinal or subretinal fibrosis was found in 12 eyes (29.2%). HDSO removal was performed after a mean period of 5.7 months (range, 3–34 months) in 34 patients. The anatomical success was 87.8%.Conclusions: The high anatomical success rate of 87.8% is a satisfactory result for these complicated RD cases. Subretinal proliferations and early emulsification limit the results. Further studies, with longer follow-ups and more patients, are needed to be conclusive. 相似文献

AIM: To investigate the anatomical and functional results and the complications in eyes operated on using vitrectomy without scleral buckling for all forms of rhegmatogenous retinal detachment (RRD). METHODS: All cases of primary RRD at the University Hospital of Lund, Lund, Sweden, treated by one surgeon during a period of 3 years were retrospectively reviewed. In 131 (98%) of 134 consecutive cases, a final follow-up record of 3-14 months was obtained, and these eyes were included in the study. The surgical protocol was tailored for each case and consisted of vitrectomy, laser photocoagulation and tamponade. Preoperative and intraoperative variables were analyses for risk for redetachment and postoperative proliferative vitreoretinopathy (PVR). RESULTS: Complete reattachment was achieved in 87% of cases (114/131) after one operation and in 95% cases after > or =1 operation. A primary detachment of >1 quadrant was the only significant risk factor for redetachment (p<0.05). The most common cause of redetachment was progressive PVR. Significant risk and factors for PVR postoperatively were a poor preoperative visual acuity and a high number of laser effects during surgery (p<0.05). The visual acuity for the total number of eyes, macula-off eyes, and pseudophakic as well as phakic eyes, improved significantly. The visual acuity for macula-on eyes did not change significantly. Six patients developed ocular hypertension and another 6 an epiretinal membrane. Three patients reported a visual field defect. Increased lens opacification was seen in 64 of the 94 (68%) phakic eyes. CONCLUSIONS: The tailored vitrectomy protocol is well suited to all types of RRD. Increased lens opacification in phakic eyes is common, but visual acuity is considerably improved in phakic as well as pseudophakic eyes. PVR development postoperatively is related to the extent of laser treatment, indicating that the protocol may be even further optimised in the future. 相似文献
