Venous thromboembolic complications have been reported in association with coronavirus disease 2019 (COVID-19) infection. We raised awareness regarding a potential temporal association between COVID-19 infection and retinal vein occlusion (RVO).Multicenter, retrospective, nonconsecutive case series.Patients presenting with hemi-RVO (HRVO) or central RVO (CRVO) between March 2020 and March 2021, with confirmed COVID-19 infection, were included. The exclusion criteria were as follows: age50 years, hypertension, diabetes, glaucoma, obesity, underlying hypercoagulable states, and those requiring intubation during hospitalization.This was a multicenter, retrospective, nonconsecutive case series including patients presenting with hemi-RVO (HRVO) or central RVO (CRVO) between March 2020 and March 2021, with confirmed COVID-19 infection. The exclusion criteria were as follows: age50 years, hypertension, diabetes, glaucoma, obesity, underlying hypercoagulable states, and those requiring intubation during hospitalization.Ophthalmic findings, including presenting and final visual acuity (VA), imaging findings, and clinical course.Twelve eyes of 12 patients with CRVO (9 of 12) or HRVO (3 of 12) after COVID-19 infection were included. The median age was 32 years (range, 18-50 years). Three patients were hospitalized, but none were intubated. The median time from COVID-19 diagnosis to ophthalmic symptoms was 6.9 weeks. The presenting VA ranged from 20/20 to counting fingers, with over half (7 of 12) having a VA of ≥20/40. OCT revealed macular edema in 42% of the eyes; of these, 80% (4 of 5) were treated with anti-VEGF injections. Ninety-two percent (11 of 12) had partial or complete resolution of ocular findings at final follow-up. Four eyes (33%) had retinal thinning, as determined using OCT, by the end of the study interval. The final VA ranged from 20/20 to 20/60, with 11 of the 12 (92%) eyes achieving a VA of ≥20/40 at a median final follow-up period of 13 weeks (range, 4-52 weeks).Although we acknowledge the high seroprevalence of COVID-19 and that a causal relationship cannot be established, we reported this series to raise awareness regarding the potential risk of retinal vascular events due to a heightened thromboinflammatory state associated with COVID-19 infection.

Purpose To evaluate the effect of one full year of the coronavirus disease 2019 (COVID-19) pandemic on clinical presentation of acute, primary rhegmatogenous retinal detachment (RRD). Design Single-center, retrospective observational cohort study. Methods Patients were divided into two cohorts; consecutive patients treated for primary RRD during the COVID-19 pandemic (March 9, 2020 to March 7, 2021; pandemic cohort) and patients treated during the corresponding time in previous year (March 11, 2019 to March 8, 2020; control cohort). Main outcome measures Proportion of patients presenting with macula-involving (mac-off) or macula-sparring (mac-on) RRD. Results 952 patients in the pandemic cohort and 872 patients in the control cohort were included. Demographic factors were similar. Compared to the control cohort, significantly greater number of pandemic cohort patients presented with mac-off RRDs ([60.92%] pandemic, [48.17%] control, P = 0.0001) and primary proliferative vitreoretinopathy (PVR; [15.53%] pandemic, [6.9%] control, P = 0.0001). Pandemic cohort patients (10.81%) had significantly higher rates of lost to follow-up compared to control cohort (4.43%; P = 0.0001). Patients new to our clinic demonstrated significant increase in mac-off RRDs in the pandemic cohort (65.35%) compared to control cohort (50.40%; P = 0.0001). Pandemic cohort patients showed worse median final best-corrected visual acuity (BCVA; 0.30 logarithm of the minimum angle of resolution [logMAR]) compared to control cohort (0.18 logMAR; P = 0.0001). Conclusions Patients with primary RRD during the first year of the COVID-19 pandemic were more likely to have mac-off disease, present with primary PVR, be lost to follow-up, and have worse final BCVA outcomes.

Background/aimsTo compare risk factors for poor visual outcomes in patients undergoing primary rhegmatogenous retinal detachment (RRD) repair and to develop a scoring system.MethodsAnalysis of the Primary Retinal detachment Outcomes (PRO) study, a multicentre interventional cohort of consecutive primary RRD surgeries performed in 2015. The main outcome measure was a poor visual outcome (Snellen VA ≤20/200).ResultsA total of 1178 cases were included. The mean preoperative and postoperative logMARs were 1.1±1.1 (20/250) and 0.5±0.7 (20/63), respectively. Multivariable logistic regression identified preoperative risk factors predictive of poor visual outcomes (≤20/200), including proliferative vitreoretinopathy (PVR) (OR 1.26; 95% CI 1.13 to 1.40), history of antivascular endothelial growth factor (VEGF) injections (1.38; 1.11 to 1.71), >1-week vision loss (1.17; 1.08 to 1.27), ocular comorbidities (1.18; 1.00 to 1.38), poor presenting VA (1.06 per initial logMAR unit; 1.02 to 1.10) and age >70 (1.13; 1.04 to 1.23). The data were split into training (75%) and validation (25%) and a scoring system was developed and validated. The risk for poor visual outcomes was 8% with a total score of 0, 17% with 1, 29% with 2, 47% with 3, and 71% with 4 or higher.ConclusionsIndependent risk factors were compared for poor visual outcomes after RRD surgery, which included PVR, anti-VEGF injections, vision loss >1 week, ocular comorbidities, presenting VA and older age. The PRO score was developed to provide a scoring system that may be useful in clinical practice.

PURPOSE To compare posterior vitreous detachment (PVD) identification rate between clinical examination versus spectral domain optical coherence tomography in patients with retinal detachment (RD). METHODS Data from the Primary Retinal Detachment Outcomes Study were used for this retrospective cross-sectional study of 506 patients. Spectral domain optical coherence tomography scans were reviewed to detect the separation of the posterior hyaloid face from the retina and the optic nerve on all 31 raster cuts of a 30 × 30 scan. Statistical analysis was performed to compare spectral domain optical coherence tomography-identified PVD with PVD identified on slit-lamp biomicroscopy. RESULTS There was a significant difference in the rate of PVD identification by clinical examination versus spectral domain optical coherence tomography in patients with RD. Clinical examination identified 51.58% of patients with PVD, whereas spectral domain optical coherence tomography identified 78.42% of patients with PVD. In patients with macula-on RD, 61.68% were found to have PVD on clinical examination versus 83.90% by imaging. Spectral domain optical coherence tomography identified larger number of PVD in patients with macula-off RD compared with clinical examination, 46.28% versus 75.43%, respectively. There was low agreement between the two methods (kappa score = 0.137). There was a significant difference in surgical procedure type chosen in those with versus without PVD. CONCLUSION Knowledge about the posterior hyaloid anatomy is important before undergoing RD repair. Spectral domain optical coherence tomography can better identify PVD than clinical examination in patients with RD.

To explore the feasibility of confocal scanning laser ophthalmoscope video for evaluation and quantification of vitreous opacities. Descriptive study outlining the utilization of dynamic confocal scanning laser ophthalmoscope video technology to capture movement of vitreous opacities. By having the patient perform a saccade followed by refixation, the vitreous gel was set in motion and the shadowing and movement of the vitreous opacities was easily visualized. The whole process of recording the images took less than a minute. Qualitative analysis showed dense shadowing from the vitreous opacities tracking over the central visual axis in some patients. Video scanning laser ophthalmo-scope can be a useful tool in documenting the presence and degree of vitreous opacities. This technology can be applied for clinical decision-making as well as educating patients. [ Ophthalmic Surg Lasers Imaging Retina 2022;53:714–716.]

Purpose To report patients who demonstrated an alteration in the clinical and optical coherence tomography features of neovascular age-related macular degeneration after resolution of endophthalmitis. Methods Retrospective case series of the subsequent changes in the macula and need for anti-vascular endothelial growth factor therapy in patients with neovascular age-related macular degeneration who developed endophthalmitis after intravitreal injection. Results The study included seven eyes of seven patients with follow-up ranging between 3 months and 11 years. The vitreous cultures (n = 7) before intravitreal antibiotic injection were the following: culture-negative (4) and coagulase-negative Staphylococcus (3). Initial treatment included vitreous tap and injection (4) and pars plana vitrectomy (3). In 5/7 eyes, the optical coherence tomography showed resolution of subretinal fluid and serous pigment epithelial detachment, and there was no additional anti-vascular endothelial growth factor treatment administered. Conclusion After successful treatment of endophthalmitis in patients with neovascular age-related macular degeneration, there was relative involution of the maculopathy and reduced anti-vascular endothelial growth factor treatment burden in this series.

PURPOSE To assess the clinical outcomes in patients with sequential, bilateral rhegmatogenous retinal detachment (RRD) by using a paired-eye comparison. DESIGN Multicenter, retrospective cohort study. PARTICIPANTS Patients with sequential, bilateral RRD treated with pars plana vitrectomy (PPV), scleral buckle (SB), or PPV plus SB over an 11-year period (October 2008-April 2019) from 4 vitreoretinal practices were included. METHODS Data were collected on patient demographics, anatomic characteristics of the RRD, surgical procedures, and best-corrected visual acuity (VA). These variables, along with single-operation anatomic success (SOAS) and type and number of surgical procedures, were assessed with a paired-eye comparison. MAIN OUTCOME MEASURES Single-operation anatomic success between the initial-eye and subsequent-eye RRD. RESULTS Five hundred four eyes of 252 patients were included. The mean interval between RRD in either eye was 13.6 ± 13.4 months. Single-operation anatomic success in the initial eye was 82.5% with a mean of 1.2 surgeries (range, 1-4 surgeries). Single-operation anatomic success in the subsequent eye was 83.7% (P = 0.80) with a mean of 1.2 surgeries (range, 1-4 surgeries; P = 0.68). Visual acuity was better in the subsequent eye at presentation (mean, 20/62 vs. 20/149; P < 0.001) and postoperative month 6 (mean, 20/41 vs. 20/49; P = 0.03), but final VA was similar (20/36 vs. 20/37; P = 0.68). Macular detachment was less prevalent (34.1% vs. 56.0%; P < 0.001) with fewer quadrants detached (mean, 1.9 quadrants vs. 2.0 quadrants; P = 0.010) in the subsequent eye. Mean duration of symptoms was shorter in the subsequent eye (mean, 5.9 days vs. 7.5 days; P = 0.008). In patients who underwent a different surgical technique in each eye, PPV plus SB yielded a higher SOAS of 89.7% compared with 69.0% for PPV alone in 116 eyes (P = 0.010). CONCLUSIONS In this study of sequential, bilateral RRD, the SOAS was similar for each eye. The second eye was more likely to be treated earlier and to have less macular involvement, but the final VA outcomes were similar. Pars plana vitrectomy plus SB yielded a significantly higher SOAS than PPV or SB alone.

Purpose: The purpose of this study was to report the closure of macular hole without surgery in 7 cases using medical therapies. Methods: The retrospective review of 7 cases of full-thickness macular holes, which closed after medical therapy without surgery. Results: Seven eyes of 7 patients developed full-thickness macular holes, which initially closed on medical therapy without surgery. Six patients were kept on maintenance therapy; 1 recurred and 5 did not develop recurrence. One patient was taken off of maintenance therapy and later developed recurrent macular hole requiring macular hole surgery. Conclusions: Medical therapy to decrease macular edema may facilitate macular hole closure and should be considered, especially for small macular holes with significant edema. Reopening of macular holes may occur after stopping topical maintenance therapy for macular edema, which occurred at 10 weeks and 9 months after maintenance therapy was discontinued or markedly tapered.

PURPOSE To describe characteristics and outcomes of primary rhegmatogenous retinal detachment in older adults (age ≥ 80). METHODS Consecutive patients with rhegmatogenous retinal detachment undergoing pars plana vitrectomy (PPV), scleral buckling (SB), or PPV/SB in the Primary Retinal Detachment Outcomes Study were evaluated. Outcome measures included single surgery anatomic success and visual acuity. RESULTS Of 2,144 patients included, 125 (6%) were 80 years or older. Compared with younger patients (age 40-79), older adults were more likely to be pseudophakic (P < 0.001), have macula-off detachments (P < 0.001), and have preoperative proliferative vitreoretinopathy (P = 0.02). In older adults, initial surgery was PPV in 73%, PPV/SB in 27%, and primary SB in 0%. Single surgery anatomic success was 78% in older adults compared with 84% in younger patients (P = 0.03). In older adults, single surgery anatomic success was 74% for PPV and 91% for PPV/SB (P = 0.03). The final mean logMAR was lower for older adults (0.79 [20/125] vs. 0.40 [20/40], [P < 0.001]). In older adults, the final mean logMAR for eyes that underwent PPV was 0.88 (20/160) compared with 0.50 (20/63) for PPV/SB (P = 0.03). CONCLUSION Octogenarians and nonagenarians presented with relatively complex pseudophakic rhegmatogenous retinal detachments. Single surgery anatomic success and visual outcomes were worse compared with younger patients, and PPV/SB had better outcomes compared with PPV alone.

Purpose of review Symptomatic vitreous opacities are increasingly recognized as a significant burden to patient well-being. There is growing interest in the use of vitrectomy or laser treatment to address these problems. This review is intended to update current assessment, management, and risks of treatment for persistent severely symptomatic vitreous opacities. Recent findings Despite studies showing the value of quantitative ultrasound, reading speed measurements, and contrast sensitivity for assessing dysfunction caused by vitreous opacities, the decision of whether to proceed with surgery remains a very subjective, clinical one. Visual Function Questionnaire-25 score studies show a very large improvement postvitrectomy consistent with relief from symptoms and patient satisfaction. The risk of retinal tear and detachment appears to be higher than in most conditions treated with vitrectomy. Summary Vitrectomy for the management of severe vitreous opacities is increasingly accepted because of the tremendous relief of symptoms reported by patients. The risks of retinal tear and detachment remain a concern, particularly in patients who have an attached posterior hyaloid. Yttrium-aluminum-garnet laser treatment of floaters may offer benefit in a subset of patients but appears to be less definitive than vitrectomy, and also may carry significant risk.

Introduction Rhegmatogenous retinal detachments with inferior retinal breaks are believed to have a higher risk of recurrent rhegmatogenous retinal detachment. This study compared anatomic and visual outcomes between primary pars plana vitrectomy (PPV) and combination PPV with scleral buckle (PPV/SB) for rhegmatogenous retinal detachments with inferior retinal breaks. Methods This is an analysis of the Primary Retinal Detachment Outcomes study, a multi-institutional cohort study of consecutive primary rhegmatogenous retinal detachment surgeries from January 1, 2015, through December 31, 2015. The primary outcome was single-surgery success rate. Only eyes with inferior retinal breaks (one break in the detached retina between five and seven o'clock) were included. Results There were 238 eyes that met the inclusion criteria, 95 (40%) of which underwent primary PPV and 163 (60%) that underwent combined PPV/SB. The single-surgery success rate was 76.8% for PPV and 87.4% for PPV/SB (P = 0.0355). This remained significant on multivariate analysis (P = 0.01). Subgroup analysis showed that a superior single-surgery success rate of PPV/SB was especially noted in phakic eyes (85.2% vs. 68.6%; P = 0.0464). Conclusion Retinal detachment with inferior retinal breaks had a higher single-surgery success rate if treated with PPV/SB compared with PPV alone, particularly in phakic eyes.

Purpose This study evaluates outcomes of comparable pseudophakic rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV) or PPV with scleral buckle (PPV-SB). Design Multicenter, retrospective, interventional cohort study. Participants Data were gathered from patients from multiple retina practices in the United States with RRD in 2015. Methods A large detailed database was generated. Pseudophakic patients with RRD managed with PPV or PPV-SB were analyzed for anatomic and visual outcomes. Eyes with proliferative vitreoretinopathy, giant retinal tears, previous invasive glaucoma surgery, and ≤90 days of follow-up were excluded from outcomes analysis. Single surgery anatomic success (SSAS) was defined as retinal attachment without ongoing tamponade and with no other RRD surgery within 90 days. Main Outcome Measures Single surgery anatomic success and final Snellen visual acuity (VA). Results A total of 1158 of 2620 eyes (44%) with primary RRD were pseudophakic. A total of 1018 eyes had greater than 90 days of follow-up. Eyes with proliferative vitreoretinopathy, previous glaucoma surgery, and giant retinal tears were excluded, leaving 893 pseudophakic eyes eligible for outcome analysis. A total of 461 (52%) were right eyes. A total of 606 patients (67%) were male, with a mean age of 65±11 years. Pars plana vitrectomy and PPV-SB as the first procedure were performed on 684 eyes (77%) and 209 eyes (23%), respectively. The mean follow-up was 388±161 days, and overall SSAS was achieved in 770 eyes (86%). Single surgery anatomic success was 84% (577/684) for PPV and 92% (193/209) for PPV-SB. The difference in SSAS between types of treatment was significant (P = 0.009). In eyes with macula-on RRD, SSAS was 88% in eyes treated with PPV and 100% in eyes treated with PPV-SB (P = 0.0088). In eyes with macula-off RRD, SSAS was 81% in eyes treated with PPV and 89% in eyes treated with PPV-SB (P = 0.029). Single surgery anatomic success was greater for PPV-SB than PPV for inferior (96% vs. 82%) and superior (90% vs. 82%) detachments. Mean final VA was similar for PPV (20/47) and PPV-SB (20/46; P = 0.805). Conclusions In pseudophakic RRDs, SSAS was better in patients treated with PPV-SB compared with PPV alone, whereas visual outcomes were similar for both groups.

Purpose: This work compares posterior retinotomy vs perfluorocarbon liquid (PFCL) for subretinal fluid (SRF) drainage during pars plana vitrectomy for primary rhegmatogenous retinal detachment (RRD). Methods: In this large, multicenter, retrospective comparative study, 2620 patients underwent pars plana vitrectomy (with or without scleral buckle) for uncomplicated RRD. Patients for whom SRF was drained via the primary break without retinotomy or PFCL were excluded; those who required both retinotomy and PFCL were similarly excluded. Remaining patients were separated into “retinotomy” and “PFCL” cohorts. Subgroup analysis was conducted for macula-on and macula-off subgroups. Postoperative outcomes were analyzed and compared. Results: A total of 760 eyes (82.7%) had retinotomy and 159 eyes (17.3%) had PFCL for drainage of SRF, and baseline characteristics between the 2 groups were similar. Postoperative analysis showed similar outcomes between the retinotomy and PFCL cohorts, including final visual acuity ( P = .19), redetachment rate ( P = .30), anatomic success ( P = .28), presence of postoperative epiretinal membrane ( P = .75), and other macular pathologies ( P > .99). Subgroup analysis yielded similar outcomes for macula-on and macula-off subgroups. Postoperative presence of retained PFCL was 2.4%, possibly a factor in the slightly higher number of subsequent surgical procedures ( P = .03) in the PFCL cohort. Conclusions: Postoperative outcomes for retinotomy vs PFCL during RRD repair are comparable, aside from slightly greater number of subsequent surgical procedures needed in the PFCL cohort. Our analysis suggests both techniques are reasonable tools in the repair of macula-on or macula-off RRD.

Purpose To detail the methodology for a large multicenter retrospective cohort study (RCS) of primary rhegmatogenous retinal detachment (RRD) with detailed data collection and to present overall anatomic outcomes. Design This study used an RCS method. Participants All patients undergoing pars plana vitrectomy (PPV), scleral buckling (SB), and combined PPV/SB for primary RRD in 2015 from 5 large retina groups were included in the database. Methods To ensure validity of the cohort method, a large and detailed database was generated. Double data entry validation was conducted, and data audits were conducted. Anatomic and visual outcomes for all the cases in the dataset will be described but not compared, because the cases were not matched. In future studies, comparable cases of moderate-complexity RRD will be chosen naive to surgeon, surgery, and outcome for subgroup analysis. Main Outcome Measures Precision of data entry was confirmed by inter-rater reliability (IRR). Main surgical outcome for each procedure type was single-surgery anatomic success (SSAS). Results Inter-rater reliability showed significant agreement among raters (P 90 days of follow-up. Of these, 320 eyes (13.7%) underwent SB, 1200 eyes (51.4%) underwent PPV, and 815 eyes (34.9%) underwent PPV/SB. The SSAS was 84.2% for PPV, 91.2% for SB, and 90.2% for PPV/SB. Conclusions We compiled a large, accurately documented database of primary RRD cases repaired by PPV, SB, and PPV/SB from which cohort studies of moderately complex RRDs can be carried out. All 3 approaches had a high SSAS rate. Procedures chosen and their outcomes are described, but the broad case mix makes comparisons not possible until future cohort studies are completed.

Purpose Anatomically similar rhegmatogenous retinal detachments (RRDs) can be treated with scleral buckle (SB), pars plana vitrectomy (PPV), or SB combined with PPV (PPV/SB). This study compares moderately complex phakic primary RRD treated with SB, PPV, or PPV/SB to review anatomic and visual outcomes. Design Multicenter, retrospective, interventional cohort study. Participants Data were gathered on all patients from multiple retina practices in the United States with RRD in 2015 and >90 days of follow-up. The cohort of phakic patients with moderately complex RRD was analyzed. Methods A large and detailed database was generated. Eyes with findings that would bias toward PPV (vitreous hemorrhage, dense cataract, proliferative vitreoretinopathy, giant retinal tear, among others) were excluded. Age Main Outcome Measures Single surgery anatomic success (SSAS), defined as retinal attachment with no other RRD surgery within 90 days, is the main outcome measure. Final visual acuity is the secondary outcome measure. Pearson’s chi-square and analysis of variance were used to test treatment effect of surgery type on SSAS and vision. Results Single surgery anatomic success was noted in 155 of 169 SB cases (91.7%), 207 of 249 PPV cases (83.1%), and 271 of 297 PPV/SB cases (91.2%). Scleral buckle and PPV/SB were superior to PPV for SSAS (P = 0.0041). For macula-on or split cases, SB had significantly better visual outcomes than PPV or PPV/SB even after controlling for cataract (cases with minimal cataract at final follow-up or after cataract surgery) (P Conclusions For phakic moderately complex primary RRDs in this study of PPV versus SB versus PPV/SB, SB had the best visual outcomes, and PPV had the worst SSAS outcomes.

Evaluate factors associated with coronavirus 2019 (COVID-19) vaccine hesitancy and clinical trends in primary rhegmatogenous retinal detachments (RRDs) during the first year of vaccine availability.Single-center, clinical cohort study.Consecutive patients from December 14, 2020, to December 12, 2021, presenting vaccinated (Prior-), subsequently vaccinated (Later-), or remaining unvaccinated (Never-Vax). Primary outcome was proportion with macula-off (mac-off) RRD. Secondary outcomes included logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA), primary proliferative vitreoretinopathy (PVR), proportion lost to follow-up, and distance traveled.1047 patients were divided into 391 Prior-, 252 Later-, and 404 Never-Vax cohorts. Significantly greater proportions of Later- and Never-Vax cohorts presented with mac-off RRDs (Prior-Vax = 44.5%; Later-Vax = 54%, P.0001; Never-Vax = 57.9%, P.0001) and primary PVR (Prior-Vax = 4.3%; Later-Vax = 13.6%, P.0001; Never-Vax = 17.1%, P.0001) compared to Prior-Vax cohort. Significantly greater proportion of Never-Vax cohort (7.7%, P.0001) were lost to follow-up compared to Prior- (2.3%) and Later-Vax (2.2%) cohorts. Never-Vax cohort (median = 35 miles) traveled farther compared to Prior- (median = 22.3 miles; P.0001) and Later-Vax cohorts (25.45 miles; P = .0038). Prior-Vax cohort had significantly better (P.05) initial (median = 0.30 logMAR) and final (0.18 logMAR) BCVA compared to Later- (Initial: 0.54 logMAR; Final: 0.30 logMAR) and Never-Vax (Initial: 0.70 logMAR; Final: 0.40 logMAR) cohorts.COVID-19 vaccine hesitancy is associated with worse clinical presentation and outcomes for primary RRD.

To compare the cost and utility of scleral buckle (SB), pars plana vitrectomy (PPV), and PPV with SB (PPV/SB) for moderately complex rhegmatogenous retinal detachment repair.Cost-utility analysis using data from the Primary Retinal Detachment Outcomes Study. The model estimated costs, lifetime utility, and lifetime cost per quality-adjusted life year for treatment of moderately complex rhegmatogenous retinal detachment with SB, PPV, or PPV/SB. Data from the Centers for Medicare and Medicaid Services were used to calculate costs in hospital and ambulatory surgery center settings.Total costs (2020 US dollars) for repair of a moderately complex rhegmatogenous retinal detachment in hospital (ambulatory surgery center) settings were $5,975 ($3,774) for the SB group, $8,125 ($5,082) for the PPV group, and $7,551 ($4,713) for the PPV/SB group. The estimated lifetime quality-adjusted life years gained were 5.4, 4.7, and 4.7 in the SB, PPV, and PPV/SB groups, respectively. The cost per quality-adjusted life year for hospital and ambulatory surgery center settings was $1,106 a ($699) for the SB group, $1729 ($1,081) for the PPV group, and $1,607 ($1,003) for the PPV/SB group.Scleral buckle, PPV, and PPV/SB yielded very favorable cost-utility results for the repair of moderately complex rhegmatogenous retinal detachment, with slightly better results for SB, compared with current willingness to pay standards.

PURPOSE To determine factors associated with 360-degree laser retinopexy (360LR) during primary pars plana vitrectomy ± scleral buckle for rhegmatogenous retinal detachment (RRD) and its impact on surgical outcomes. METHODS This is a multicenter, retrospective, interventional study. Patients undergoing primary pars plana vitrectomy or primary pars plana vitrectomy + scleral buckle for noncomplex primary RRD in 2015 were evaluated. Primary outcomes were single surgery anatomical success (SSAS) and final anatomical success. Secondary outcomes included final logarithm of the minimum angle of resolution visual acuity, epiretinal membrane formation, cystoid macular edema development, and number of subsequent vitrectomies. Multivariate regressions were performed. RESULTS Two thousand two hundred and forty-eight surgeries by 61 surgeons were included; of which, 516 underwent 360LR. Younger age (P = 0.01), more retinal breaks (P = 0.01), more extensive RRD (P < 0.001), and surgeon ID (P < 0.001) were significantly associated with 360LR. No significant associations between 360LR and single surgery anatomical success (P = 0.44), epiretinal membrane formation (P = 0.14), cystoid macular edema development (P = 0.28), or number of subsequent vitrectomies (P = 0.41) were found. Controlling for case complexity, 360LR was significantly associated with lower final anatomical success (P < 0.001) and worse final logarithm of the minimum angle of resolution visual acuity (P < 0.001). CONCLUSION Multiple factors influenced whether 360LR was performed during primary pars plana vitrectomy ± scleral buckle for RRD. However, 360LR was not associated with improved surgical outcomes, and in fact, it may be associated with poorer outcomes.

Purpose To determine predictive factors of proliferative vitreoretinopathy (PVR) formation after uncomplicated primary retinal detachment repair. Methods Retrospective, single-center, case-control study of 74 consecutive patients with (37 eyes) and without (37 eyes) PVR formation after undergoing uncomplicated primary surgery for retinal detachment repair. Logistic regression was used to assess factors associated with PVR formation. Results Retinal detachment involving the macula was 4.2 times (adjusted odds ratio; 95% confidence interval, 1.4-12.9; P = 0.0119) more likely to have PVR formation compared with those without. Patients who were current or former smokers were 3.6 times (adjusted odds ratio; 95% confidence interval, 1.1-11.7; P = 0.0352) more likely to have PVR formation compared with nonsmokers. Compared with 25-gauge (g) vitrectomy, larger gauge vitrectomy (20 g or 23 g) was 3.6 times (adjusted odds ratio; 95% confidence interval, 1.2-11.3; P = 0.0276) more likely to have PVR formation. Duration of retinal detachment symptoms, high myopia, lens status, lattice degeneration, location of retinal break, number of retinal breaks, and surgical technique (e.g., scleral buckle with or without vitrectomy versus vitrectomy alone) were not found to be predictive of PVR formation. Conclusion Cigarette smoking and macular involvement are significant risk factors predictive of PVR formation after uncomplicated primary retinal detachment repair.

Cystoid macular edema (CME) following cataract surgery is a well-known entity. Less is known regarding the risk factors of developing CME following repair of rhegmatogenous retinal detachments (RRD...

To identify differences in preoperative characteristics and intraoperative approaches between surgeons with higher versus lower single surgery success rates (SSSR) for repair of rhegmatogenous retinal detachments (RRDs).This study is a sub-analysis of subjects who underwent RRD repair in the Primary Retinal Detachment Outcomes (PRO) study, a multi-institutional, retrospective comparative interventional study. The PRO study examined consecutive primary RRD surgeries from January 1, 2015 through December 31, 2015. The primary outcome was variations in surgical approach to different types of RRDs with secondary analyses of pre and intraoperative metrics for surgeons with SSSR 90% compared to those80% who performed at least 40 operations during the study period.A total of 689 surgeries were included in the analysis. The mean SSSR was 94% for the higher tier and 75% for the lower tier (p 0.0001). Surgeons with90% SSSR were more likely to have graduated fellowship more recently (p = 0.0025), use less perfluorocarbon liquid (p 0.0001), perform less 360 degree laser retinopexy (p 0.0001), and perform a higher percentage of primary buckles and combined PPV/SB (p 0.0001). For pseudophakic eyes there was no difference between PPV and PPV/SB use (p = 0.6211).Surgeons with high SSSR typically performed SB as well as combination PPV/SB for more RRDs. Similar numbers of PPV and PPV/SB were performed for pseudophakic eyes, suggesting that the difference in SSSR between the two groups may be related to a combination of preoperative and intraoperative decisions as well as differences in technique.

Rhegmatogenous retinal detachments with inferior retinal breaks are believed to have a higher risk of recurrent rhegmatogenous retinal detachment. This study compared anatomic and visual outcomes between primary pars plana vitrectomy (PPV) and combination PPV with scleral buckle (PPV/SB) for rhegmatogenous retinal detachments with inferior retinal breaks.This is an analysis of the Primary Retinal Detachment Outcomes study, a multi-institutional cohort study of consecutive primary rhegmatogenous retinal detachment surgeries from January 1, 2015, through December 31, 2015. The primary outcome was single-surgery success rate. Only eyes with inferior retinal breaks (one break in the detached retina between five and seven o'clock) were included.There were 238 eyes that met the inclusion criteria, 95 (40%) of which underwent primary PPV and 163 (60%) that underwent combined PPV/SB. The single-surgery success rate was 76.8% for PPV and 87.4% for PPV/SB (P = 0.0355). This remained significant on multivariate analysis (P = 0.01). Subgroup analysis showed that a superior single-surgery success rate of PPV/SB was especially noted in phakic eyes (85.2% vs. 68.6%; P = 0.0464).Retinal detachment with inferior retinal breaks had a higher single-surgery success rate if treated with PPV/SB compared with PPV alone, particularly in phakic eyes.

To assess the clinical outcomes in patients with sequential, bilateral rhegmatogenous retinal detachment (RRD) by using a paired-eye comparison.Multicenter, retrospective cohort study.Patients with sequential, bilateral RRD treated with pars plana vitrectomy (PPV), scleral buckle (SB), or PPV plus SB over an 11-year period (October 2008-April 2019) from 4 vitreoretinal practices were included.Data were collected on patient demographics, anatomic characteristics of the RRD, surgical procedures, and best-corrected visual acuity (VA). These variables, along with single-operation anatomic success (SOAS) and type and number of surgical procedures, were assessed with a paired-eye comparison.Single-operation anatomic success between the initial-eye and subsequent-eye RRD.Five hundred four eyes of 252 patients were included. The mean interval between RRD in either eye was 13.6 ± 13.4 months. Single-operation anatomic success in the initial eye was 82.5% with a mean of 1.2 surgeries (range, 1-4 surgeries). Single-operation anatomic success in the subsequent eye was 83.7% (P = 0.80) with a mean of 1.2 surgeries (range, 1-4 surgeries; P = 0.68). Visual acuity was better in the subsequent eye at presentation (mean, 20/62 vs. 20/149; P0.001) and postoperative month 6 (mean, 20/41 vs. 20/49; P = 0.03), but final VA was similar (20/36 vs. 20/37; P = 0.68). Macular detachment was less prevalent (34.1% vs. 56.0%; P 0.001) with fewer quadrants detached (mean, 1.9 quadrants vs. 2.0 quadrants; P = 0.010) in the subsequent eye. Mean duration of symptoms was shorter in the subsequent eye (mean, 5.9 days vs. 7.5 days; P = 0.008). In patients who underwent a different surgical technique in each eye, PPV plus SB yielded a higher SOAS of 89.7% compared with 69.0% for PPV alone in 116 eyes (P = 0.010).In this study of sequential, bilateral RRD, the SOAS was similar for each eye. The second eye was more likely to be treated earlier and to have less macular involvement, but the final VA outcomes were similar. Pars plana vitrectomy plus SB yielded a significantly higher SOAS than PPV or SB alone.

BACKGROUND AND OBJECTIVE: Most surgeons now utilize small-gauge (23- or 25-gauge) pars plana vitrectomy (PPV) with or without scleral buckling for repair of rhegmatogenous retinal detachments (RRD), in addition to primary scleral buckle (SB), but comparative data between the two gauges are limited. PATIENTS AND METHODS: This study is an analysis of primary RRD repairs comparing 23- versus 25-gauge vitrectomy for PPV or combination PPV/SB from January 1, 2015, through December 31, 2015, across multiple institutions. The primary outcome was single-surgery success and secondary outcomes included postoperative complications. RESULTS: There were 1,932 eyes that met inclusion criteria. There was no statistically significant difference in single-surgery success (82.9% vs. 83.8%; P = 0.6329). There were similar rates of postoperative hypotony, endophthalmitis, vitreous hemorrhage, and choroidal detachment. The findings were similar when analyzing only eyes that underwent primary PPV without SB. CONCLUSION: Both 23- and 25-gauge vitrectomy systems have similar anatomic and visual outcomes in the primary repair of RRD. [ Ophthalmic Surg Lasers Imaging Retina. 2021;52:70–76.]

BACKGROUND AND OBJECTIVE: Non-causal macular holes (MHs) can occur concurrently with rhegmatogenous retinal detachments (RRDs). The visual outcomes and surgical approach for these eyes are variable. PATIENTS AND METHODS: This was a multi-institutional, retrospective review of all primary retinal detachment surgeries from January 1, 2015, through December 31, 2015. Pre-, intra-, and postoperative metrics were recorded. RESULTS: There were 2,242 eyes that had pars plana vitrectomy for primary RRD, 43 (1.9%) of which had a MH at the time of surgery. The mean postoperative logMAR visual acuity (VA) for the MH cohort was 0.87 ± 0.64 (20/148) and for eyes without a MH was 0.47 ± 0.63 (20/59; P < .0001). The single-surgery re-attachment rate for the MH cohort and no MH cohort was 86.1% and 84.9%, respectively ( P = 1.0000). CONCLUSIONS: Patients with noncausal MHs and RRD had significantly worse VA than patients without a MH. Preoperative counseling is imperative in patients with both RRD and MH.

This study evaluates outcomes of comparable pseudophakic rhegmatogenous retinal detachment (RRD) treated with pars plana vitrectomy (PPV) or PPV with scleral buckle (PPV-SB).Multicenter, retrospective, interventional cohort study.Data were gathered from patients from multiple retina practices in the United States with RRD in 2015.A large detailed database was generated. Pseudophakic patients with RRD managed with PPV or PPV-SB were analyzed for anatomic and visual outcomes. Eyes with proliferative vitreoretinopathy, giant retinal tears, previous invasive glaucoma surgery, and ≤90 days of follow-up were excluded from outcomes analysis. Single surgery anatomic success (SSAS) was defined as retinal attachment without ongoing tamponade and with no other RRD surgery within 90 days.Single surgery anatomic success and final Snellen visual acuity (VA).A total of 1158 of 2620 eyes (44%) with primary RRD were pseudophakic. A total of 1018 eyes had greater than 90 days of follow-up. Eyes with proliferative vitreoretinopathy, previous glaucoma surgery, and giant retinal tears were excluded, leaving 893 pseudophakic eyes eligible for outcome analysis. A total of 461 (52%) were right eyes. A total of 606 patients (67%) were male, with a mean age of 65±11 years. Pars plana vitrectomy and PPV-SB as the first procedure were performed on 684 eyes (77%) and 209 eyes (23%), respectively. The mean follow-up was 388±161 days, and overall SSAS was achieved in 770 eyes (86%). Single surgery anatomic success was 84% (577/684) for PPV and 92% (193/209) for PPV-SB. The difference in SSAS between types of treatment was significant (P = 0.009). In eyes with macula-on RRD, SSAS was 88% in eyes treated with PPV and 100% in eyes treated with PPV-SB (P = 0.0088). In eyes with macula-off RRD, SSAS was 81% in eyes treated with PPV and 89% in eyes treated with PPV-SB (P = 0.029). Single surgery anatomic success was greater for PPV-SB than PPV for inferior (96% vs. 82%) and superior (90% vs. 82%) detachments. Mean final VA was similar for PPV (20/47) and PPV-SB (20/46; P = 0.805).In pseudophakic RRDs, SSAS was better in patients treated with PPV-SB compared with PPV alone, whereas visual outcomes were similar for both groups.

BACKGROUND AND OBJECTIVE: There is currently no objective measure of the visual deficits experienced by patients with symptomatic vitreous opacities (SVOs) that would also correlate with the functional improvement they report following vitrectomy. This study aims to determine whether reading speed can be used as a reliable outcome measure to assess objectively the impact of both SVOs and vitrectomy on patients' visual performance. PATIENTS AND METHODS: Twenty adult patients seeking surgery for SVO were included. Measures of visual function were obtained before and after vitrectomy using the Early Treatment Diabetic Retinopathy Study acuity chart, the National Eye Institute Visual Function Questionnaire, and the MNREAD acuity chart. RESULTS: In patients with nonopacified lenses (n = 10), maximum reading speed increased significantly from 138 to 159 words per minute after complete removal of SVOs by vitrectomy (95% confidence interval, 14–29; P < .001). CONCLUSIONS: Reading speed is impaired with SVOs and improves following vitrectomy in phakic and pseudophakic eyes with clear lenses. Reading speed is a valid objective measure to assess the positive effect of vitrectomy for SVOs on near-distance daily life activities. [ Ophthalmic Surg Lasers Imaging Retina . 2020;51:456–466.]

Purpose We describe the presentation of patients developing endophthalmitis after intravitreal injection with vascular endothelial growth factor (VEGF) inhibitors. Moreover, we evaluate the management by comparing the outcomes of immediate tap and injection of intravitreal antibiotics (TAI) versus initial surgical pars plana vitrectomy (PPV). Finally, we analyze the predictive factors of visual outcomes at 6-month follow-up. Design Retrospective, single-center, nonrandomized interventional study. Participants Patients developing endophthalmitis after receiving an intravitreal injection of anti-VEGF agent between 2006 and 2016. Methods All patients received a vitreous biopsy sent for cultures before the initiation of treatment: TAI group versus PPV with intravitreal antibiotics (PPV group). Main Outcome Measures Best-corrected visual acuity (BCVA) at 6-month follow-up after treatment for endophthalmitis. Results A total of 258 357 intravitreal injections occurred over the course of the 10-year period, of which 40 patients (0.016%) had endophthalmitis within 3 weeks after injection. In total, 34 patients (85.0%) had pain and 25 patients (62.5%) had hypopyon on initial examination. Among 24 culture-positive cases, 66.7% of the causative organisms were coagulase-negative Staphylococcus , followed by Streptococcus species (10.0%). The best-corrected visual acuity (BCVA) (logarithm of the minimum angle of resolution [logMAR]) at 6-month follow-up was significantly worse for patients who had a positive culture for Streptococcus species (4.0; standard deviation [SD], 0.8) (approximately light perception) compared with those who had a positive culture for coagulase-negative Staphylococcus (0.4; SD, 0.3) (∼20/50) ( P P = 0.03). There was no statistically significant difference in BCVA at 6-month follow-up between the TAI and PPV groups. Younger age ( Conclusions No significant difference in BCVA at 6-month follow-up was detected between the TAI and PPV groups. Younger age and lower IOP at presentation were associated with better visual outcomes at 6-month follow-up.

Background/aimsVitrectomy to repair retinal detachment is often performed with either non-contact wide-angle viewing systems or wide-angle contact viewing systems. The purpose of this study is to assess whether the viewing system used is associated with any differences in surgical outcomes of vitrectomy for primary non-complex retinal detachment repair.MethodsThis is a multicenter, interventional, retrospective, comparative study. Eyes that underwent non-complex primary retinal detachment repair by either pars plana vitrectomy (PPV) alone or in combination with scleral buckle/PPV in 2015 were evaluated. The viewing system at the time of the retinal detachment repair was identified and preoperative patient characteristics, intraoperative findings and postoperative outcomes were recorded.ResultsA total of 2256 eyes were included in our analysis. Of those, 1893 surgeries used a non-contact viewing system, while 363 used a contact lens system. There was no statistically significant difference in single surgery anatomic success at 3 months (p=0.72), or final anatomic success (p=0.40). Average postoperative visual acuity for the contact-based cases was logMAR 0.345 (20/44 Snellen equivalent) compared with 0.475 (20/60 Snellen equivalent) for non-contact (p=0.001). After controlling for numerous confounding variables in multivariable analysis, viewing system choice was no longer statistically significant (p=0.097).ConclusionThere was no statistically significant difference in anatomic success achieved for primary retinal detachment repair when comparing non-contact viewing systems to contact lens systems. Postoperative visual acuity was better in the contact-based group but this was not statistically significant when confounding factors were controlled for.

Anatomically similar rhegmatogenous retinal detachments (RRDs) can be treated with scleral buckle (SB), pars plana vitrectomy (PPV), or SB combined with PPV (PPV/SB). This study compares moderately complex phakic primary RRD treated with SB, PPV, or PPV/SB to review anatomic and visual outcomes.Multicenter, retrospective, interventional cohort study.Data were gathered on all patients from multiple retina practices in the United States with RRD in 2015 and90 days of follow-up. The cohort of phakic patients with moderately complex RRD was analyzed.A large and detailed database was generated. Eyes with findings that would bias toward PPV (vitreous hemorrhage, dense cataract, proliferative vitreoretinopathy, giant retinal tear, among others) were excluded. Age40 years (bias toward SB) was excluded. Comparable cases of moderately complex RRD were then chosen naive to surgeon, surgery, and outcome for subgroup analysis.Single surgery anatomic success (SSAS), defined as retinal attachment with no other RRD surgery within 90 days, is the main outcome measure. Final visual acuity is the secondary outcome measure. Pearson's chi-square and analysis of variance were used to test treatment effect of surgery type on SSAS and vision.Single surgery anatomic success was noted in 155 of 169 SB cases (91.7%), 207 of 249 PPV cases (83.1%), and 271 of 297 PPV/SB cases (91.2%). Scleral buckle and PPV/SB were superior to PPV for SSAS (P = 0.0041). For macula-on or split cases, SB had significantly better visual outcomes than PPV or PPV/SB even after controlling for cataract (cases with minimal cataract at final follow-up or after cataract surgery) (P0.001).For phakic moderately complex primary RRDs in this study of PPV versus SB versus PPV/SB, SB had the best visual outcomes, and PPV had the worst SSAS outcomes.

To determine factors associated with 360-degree laser retinopexy (360LR) during primary pars plana vitrectomy ± scleral buckle for rhegmatogenous retinal detachment (RRD) and its impact on surgical outcomes.This is a multicenter, retrospective, interventional study. Patients undergoing primary pars plana vitrectomy or primary pars plana vitrectomy + scleral buckle for noncomplex primary RRD in 2015 were evaluated. Primary outcomes were single surgery anatomical success (SSAS) and final anatomical success. Secondary outcomes included final logarithm of the minimum angle of resolution visual acuity, epiretinal membrane formation, cystoid macular edema development, and number of subsequent vitrectomies. Multivariate regressions were performed.Two thousand two hundred and forty-eight surgeries by 61 surgeons were included; of which, 516 underwent 360LR. Younger age (P = 0.01), more retinal breaks (P = 0.01), more extensive RRD (P0.001), and surgeon ID (P0.001) were significantly associated with 360LR. No significant associations between 360LR and single surgery anatomical success (P = 0.44), epiretinal membrane formation (P = 0.14), cystoid macular edema development (P = 0.28), or number of subsequent vitrectomies (P = 0.41) were found. Controlling for case complexity, 360LR was significantly associated with lower final anatomical success (P0.001) and worse final logarithm of the minimum angle of resolution visual acuity (P0.001).Multiple factors influenced whether 360LR was performed during primary pars plana vitrectomy ± scleral buckle for RRD. However, 360LR was not associated with improved surgical outcomes, and in fact, it may be associated with poorer outcomes.

To evaluate potential accumulation of fluid in the outer choroid in eyes with central serous chorioretinopathy.Retrospective observational case series.Patients in 2 community-based retinal practices were evaluated for hyporeflective areas in the outer choroid consistent with collections of fluid using enhanced depth imaging optical coherence tomography. Eligible patients were examined over the preceding 2 years, had a history of central serous chorioretinopathy, and did not have a history of choroidal neovascularization or photodynamic therapy.In the New York group there were 131 eyes of 70 patients who had a mean age of 56.3 (± 12.5) years, and 88 (67.2%) had hyporeflective regions consistent with posterior loculation of fluid in the macular region. In the Minnesota data set there were 91 eyes of 48 patients who had a mean age of 47.9 (± 9.9) years and hyporeflective regions consistent with posterior loculation of fluid was present in 59 (64.8%). In the entire group the mean subfoveal choroidal thickness of those without loculated fluid was 344 μm, as compared with 498 μm with loculated fluid (P.001). The areas of loculated fluid were hyporeflective, were larger topographically than the large choroidal vessels, had an angular inner border, and did not have a bounding vascular wall.Posterior loculation of fluid is a common finding in central serous chorioretinopathy, but it has a different pattern and distribution than do collections of fluid in the outer choroid and suprachoroidal space as seen in other forms of choroidal effusion.

Purpose To present a case of central serous chorioretinopathy (CSC) treatment with spironolactone in a challenge-rechallenge pattern. Methods At presentation, fundus photography, fluorescein angiography, spectral domain optical coherence tomography, and enhanced depth imaging ocular coherence tomography were performed in both eyes. The patient was prescribed 25 mg spironolactone daily along with serum potassium monitoring. At follow-ups, spectral domain optical coherence tomography and enhanced depth imaging ocular coherence tomography were performed. Results A 37-year-old white male accountant presenting with CSC. Spironolactone treatment resolved the CSC. After the patient discontinued treatment, it returned. After returning to daily treatment, the CSC again resolved. Conclusion Spironolactone was an effective treatment of CSC in this case. Other groups have reported similar findings with eplerenone, a similar drug.

We describe the presentation of patients developing endophthalmitis after intravitreal injection with vascular endothelial growth factor (VEGF) inhibitors. Moreover, we evaluate the management by comparing the outcomes of immediate tap and injection of intravitreal antibiotics (TAI) versus initial surgical pars plana vitrectomy (PPV). Finally, we analyze the predictive factors of visual outcomes at 6-month follow-up.Retrospective, single-center, nonrandomized interventional study.Patients developing endophthalmitis after receiving an intravitreal injection of anti-VEGF agent between 2006 and 2016.All patients received a vitreous biopsy sent for cultures before the initiation of treatment: TAI group versus PPV with intravitreal antibiotics (PPV group).Best-corrected visual acuity (BCVA) at 6-month follow-up after treatment for endophthalmitis.A total of 258 357 intravitreal injections occurred over the course of the 10-year period, of which 40 patients (0.016%) had endophthalmitis within 3 weeks after injection. In total, 34 patients (85.0%) had pain and 25 patients (62.5%) had hypopyon on initial examination. Among 24 culture-positive cases, 66.7% of the causative organisms were coagulase-negative Staphylococcus, followed by Streptococcus species (10.0%). The best-corrected visual acuity (BCVA) (logarithm of the minimum angle of resolution [logMAR]) at 6-month follow-up was significantly worse for patients who had a positive culture for Streptococcus species (4.0; standard deviation [SD], 0.8) (approximately light perception) compared with those who had a positive culture for coagulase-negative Staphylococcus (0.4; SD, 0.3) (∼20/50) (P0.0001). Compared with the TAI group, a higher proportion of samples were culture-positive in the PPV group (90.9% vs. 48.3%, P = 0.03). There was no statistically significant difference in BCVA at 6-month follow-up between the TAI and PPV groups. Younger age (85 years) and lower intraocular pressure (IOP) (≤25 mmHg) at presentation were predictive of achieving a BCVA of 20/400 or better at 6-month follow-up after treatment. Initial management (TAI vs. PPV), duration of symptoms, presence of pain, presence of hypopyon, presenting BCVA, and culture status (positive vs. negative) were not found to be predictive of visual outcomes at 6-month follow-up.No significant difference in BCVA at 6-month follow-up was detected between the TAI and PPV groups. Younger age and lower IOP at presentation were associated with better visual outcomes at 6-month follow-up.

Purpose: To report the outcome for eyes treated with intravitreal injection of bevacizumab combined with verteporfin photodynamic therapy (PDT) for choroidal neovascularization (CNV) in age-related macular degeneration (AMD). Study Design and Participants: Interventional, consecutive, retrospective case series including 40 eyes of 40 patients with newly diagnosed juxtafoveal or subfoveal CNV secondary to AMD. Methods: The charts of patients treated with a 1.25-mg intravitreal injection of bevacizumab followed by PDT within a 2-week period were reviewed. Main outcome measures were visual acuity stabilization (defined as no change or a gain in visual acuity) and need for retreatment. Results: Thirty-three (83%) of 40 eyes had stabilization of visual acuity. Mean improvement in visual acuity was 1.73 lines. Twenty-six eyes (65%) required only a single intravitreal injection of bevacizumab combined with PDT. Of the 23 eyes with 12 months of follow-up, 17 (74%) had stabilization of visual acuity, while 9 (40%) had improvement in visual acuity (mean, 1.22 Snellen lines). Eleven eyes (48%) required only a single combined treatment for CNV resolution at the 12-month follow-up. Fifteen (88%) of 17 eyes with only 6 months of follow-up required only a single combined treatment. There were no complications such as endophthalmitis, uveitis, or ocular hypertension. Conclusion: These findings suggest that eyes treated with both intravitreal injection of bevacizumab and PDT require none to a minimal number of re-treatments to have stabilization of vision, even at 12 months of follow-up. Further investigation with large controlled trials is warranted to outline the appropriate treatment paradigm for combination therapy.

Angiogenesis is a common factor in the pathogenesis of cancer and in exudative age-related macular degeneration (AMD). Therefore, angiogenesis inhibition has been developed as a therapeutic strategy. We report 2 cases of recurrent exudative AMD in which oral sorafenib, a tyrosine kinase inhibitor approved for cancer, was added to intravitreal ranibizumab, an antibody to vascular endothelial growth factor. These 2 patients were followed up by determination of visual acuity, fluorescein angiography, fundoscopy, and optical coherence tomography. The visual acuity of 1 patient improved from 20/70 to 20/60 while he was receiving sorafenib therapy; that of the other did not. Marked improvement was noted in both patients on optical coherence tomography. Additionally, both patients appeared to receive some benefit when low-dose oral sorafenib was used as monotherapy after its initial addition to ranibizumab therapy. Randomized trials of adding sorafenib to standard therapy for patients with neovascular AMD should be considered.

Purpose To describe the clinical course of patients undergoing vitreoretinal procedures while receiving systemic anticoagulation with warfarin. Methods We reviewed patient demographics, ocular findings, and clinical courses for 25 patients receiving systemic anticoagulation with warfarin who subsequently underwent vitreoretinal surgery. Results Patient ages ranged from 49 years to 81 years (median, 69 years). Indications for anticoagulation included atrial fibrillation, cerebrovascular disease, deep vein thrombosis, prosthetic heart valves, and hypercoagulable state. Follow-up ranged from 4 months to 36 months (median, 19.5 months). The international normalized ratio ranged from 1.5 to 3.1 (median, 2.0). Final vision after surgery ranged from 20/20 to 20/400 (median, 20/100). One patient who underwent scleral buckling and external drainage of subretinal fluid had an intraoperative subretinal hemorrhage associated with the drainage procedure. In all other patients, no intraoperative complications occurred. Conclusion Cessation of therapy with warfarin may not be necessary in patients receiving anticoagulation who are undergoing vitreoretinal procedures. Successful visual and anatomical results may be achieved after vitreoretinal surgery for patients receiving anticoagulation with warfarin. The management of anticoagulation should occur in conjunction with the patient's internist to allow a clear understanding of the potential systemic risks of cessation of warfarin treatment preoperatively.
