Conversion to faricimab after prior anti-vascular endothelial growth factor therapy for persistent diabetic macular oedema.

BACKGROUND: To assess the anatomical and functional outcomes in eyes with persistent diabetic macular oedema (pDME) on chronic anti-vascular endothelial growth factor therapy switched to intravitreal faricimab. METHODS: Patients with pDME on chronic anti-vascular endothelial growth factor therapy that were switched to faricimab and received at least three injections at our institution between April 2022 and May 2023 were included in this study. Patients were excluded if they had complete response to previous treatment but were switched to extend treatment intervals if they had steroid or laser treatment for DME within 6 months prior to switch. Clinical and imaging data were extracted from the electronic medical record. Central foveal thickness (CFT) and Snellen visual acuity (VA) were obtained before and after three intravitreal faricimab injections. Generalised estimating equations were used to analyse the change in CFT and VA. RESULT: During the study period, 69 eyes of 53 patients met inclusion criteria. The mean age was 68.6±9.0 years. The mean number of injections prior to switch was 18.1±16.0. Pre-switch mean logarithm of the minimal angle of resolution VA was 0.40±0.30 (Snellen equivalent 20/50) and 0.38±0.27 (Snellen equivalent 20/48) after three faricimab injections (p=0.397). Mean CFT improved from 380±155 microns to 323±147 microns (p<0.001). No ophthalmic or systemic adverse events occurred during the study period. CONCLUSIONS: Intravitreal faricimab can improve anatomic outcomes while maintaining visual acuity in eyes with pDME previously treated with anti-VEGF therapy.

Surgical Management of Full-Thickness Macular Holes in Macular Telangiectasia Type 2: A Global Multicenter Study.

PURPOSE: To report on macular hole repair in macular telangiectasia type 2 (MacTel2). DESIGN: Global, multicenter, retrospective case series. PARTICIPANTS: Patients undergoing surgery for MacTel2-associated full-thickness macular hole (MTMH). METHODS: Standardized data collection sheet distributed to all surgeons. MAIN OUTCOME MEASURES: Anatomic closure and visual outcomes of MTMH. RESULTS: Sixty-three surgeries in 47 patients with MTMH were included from 30 surgeons. Mean age was 68.1 years, with 62% female, 72% White, 21% East or South Asian, 2% African American, and 2% Hispanic or Latino. Procedures included 34 internal limiting membrane (ILM) peeling alone, 22 ILM flaps, 5 autologous retinal transplantations (ARTs), 1 retinotomy, and 1 subretinal bleb. For ILM peeling, preoperative visual acuity (VA) was 0.667 ± 0.423 logarithm of the minimum angle of resolution (logMAR). Minimum hole diameter (MHD) was 305.5 ± 159.4 µm (range, 34-573 µm). Sixteen of 34 ILM peels (47%) resulted in MTMH closure. At postoperative month 6, VA was stable at 0.602 ± 0.516 logMAR (P = 0.65). VA improved by at least 2 lines in 43% and at least 4 lines in 24%. For ILM flaps, preoperative VA was 0.878 ± 0.552 logMAR. MHD was 440.8 ± 175.5 µm (range, 97-697 µm), which was significantly larger than for ILM peels (P < 0.01). Twenty of 22 ILM flaps (90%) resulted in MTMH closure, which was significantly higher than for ILM peels (P < 0.01). At postoperative month 6, VA improved to 0.555 ± 0.405 logMAR (P < 0.05). VA improved by at least 2 lines in 56% and at least 4 lines in 28%. For ARTs, preoperative VA was 1.460 ± 0.391 logMAR. MHD was 390.2 ± 203.7 µm (range, 132-687 µm). All 5 ARTs (100%) resulted in MTMH closure. At postoperative month 6, VA was stable at 1.000 ± 0.246 logMAR (P = 0.08). Visual acuity improved at least 2 lines in 25%. CONCLUSIONS: Surgical closure of macular holes improved VA in 57% of MTMHs. Internal limiting membrane flaps achieved better anatomic and functional outcomes than ILM peeling alone. Autologous retinal transplantation may be an option for refractory MTMHs.

Incidence and Outcomes of Recurrent Retinal Detachment after Cataract Surgery in Eyes with Prior Retinal Detachment Repair.

OBJECTIVE: To investigate the incidence and outcomes of recurrent retinal detachment (RD) after cataract extraction (CE). DESIGN: Retrospective case series. SUBJECTS: Phakic eyes with RD that were successfully repaired with pneumatic retinopexy (PR), scleral buckle (SB), pars plana vitrectomy (PPV), or combined PPV/SB and subsequently underwent cataract surgery. METHODS: A retrospective review of phakic eyes that underwent successful RD repair followed by subsequent cataract surgery between April 2012 and January 2023 was performed. Patients with multiple RD surgeries before CE and those with silicone oil tamponade before cataract surgery were excluded. Eyes that redetached were matched 1:2 with eyes that did not redetach after cataract surgery. MAIN OUTCOME MEASURES: Incidence of redetachment after cataract surgery as well as visual and anatomic outcomes at 6 months after first redetachment and at the final visit. RESULTS: Of 4833 phakic eyes at the time of initial RD, 1893 patients (39.2%) underwent cataract surgery. After applying exclusion criteria, 763 patients were included. The mean (standard deviation) duration of follow-up was 48.4 (29.1) months. The overall incidence of retinal redetachment after cataract surgery was 2.5% (19/763 eyes). The rate of redetachment based on the type of initial RD repair was 9.1% (1/11), 5.3% (2/38), 2.8% (9/317), and 1.8% (7/397) for PR, SB, PPV, and combined PPV/SB, respectively (P = 0.24). The median (interquartile range [IQR]; range) duration between the cataract surgery and first redetachment was 301 (104-1222; 8-2760) days. Single surgery anatomic success for the RD repair after cataract surgery was achieved in 17 eyes (89.5%) at 3 months and 14 eyes (73.7%) at 6 months and at the final visit. Final anatomic success rate for reattachment was 100% (19/19). The median (IQR) logarithm of the minimal angle of resolution visual acuity (VA) at the final visit was 1.00 (0.18-2.00, Snellen equivalent, 20/200) with significant worsening compared with vision after cataract surgery (0.18 [0.10-0.48], 20/30) (P = 0.001). CONCLUSION: Recurrent RD was not uncommon in patients with a prior history of RD repair after CE. Reoperation resulted in relatively favorable anatomic success but there were declines in VA.

Endophthalmitis After Intravitreal Anti-Vascular Endothelial Factor Injections: Outcomes of Eyes Managed Without Microbiologic Cultures.

PURPOSE: To evaluate outcomes of eyes that developed endophthalmitis after intravitreal anti-vascular endothelial growth factor injections that were managed without microbiologic cultures. DESIGN: Retrospective, single-center, comparative cohort study. METHODS: We included all eyes with postinjection endophthalmitis from July 1, 2013, to September 1, 2019. Endophthalmitis cases were divided into the culture group if treated with intravitreal antibiotics and a vitreous or aqueous tap sent for microbiologic sampling or into the no culture group if treated with immediate injection of intravitreal antibiotics with an anterior chamber paracentesis that was not sent for microbiologic sampling. The main outcome measures were visual acuity, the incidence of retinal detachment, and the need for additional procedures. RESULTS: Of 165 endophthalmitis cases identified, 119 (72%) were in the culture group and 46 (28%) were in the no culture group. At endophthalmitis presentation, eyes in the culture group had a mean logMAR VA of 1.98 (∼20/1900) compared with 1.90 (∼20/1600) for eyes in the no culture group (P = .589). At the 6-month follow-up, the mean vision loss was 5.5 lines lost from baseline for the culture group compared with 2.5 lines lost for the no culture group (P = .017). Eyes in the culture group required a subsequent pars plana vitrectomy in 29 of 119 cases (24%) compared with 7 of 46 cases (15%) in the no culture group (P = .29). Six of 119 eyes (5%) in the culture group developed secondary retinal detachments compared with none in the no culture group (P = .143). CONCLUSIONS: When access to microbiologic facility is not available, the management of postinjection endophthalmitis using intravitreal antibiotics without microbiologic cultures may be an acceptable treatment strategy.

Outcomes of eyes with retinal vein occlusion that are lost to follow-up after antivascular endothelial growth factor therapy.

BACKGROUND/AIMS: To evaluate the outcomes of eyes with macular oedema due to retinal vein occlusion (RVO) that are lost to follow-up (LTFU) after antivascular endothelial growth factor (VEGF) injections. METHOD: A retrospective, single-centre, consecutive case series of RVO patients receiving injections who were LTFU >6 months was conducted. Data were collected from the visit before LTFU; return visit; 3 months, 6 months and 12 months after return; and the final visit. RESULTS: Ninety eyes of 83 patients were included. Fifty (55.5%) eyes had branch RVO and 40 (44.5%) had central RVO. Mean LTFU duration was 277.8 days with additional mean follow-up for 748.1 days after return. Mean logarithm of the minimum angle of resolution visual acuity (VA) (Snellen) at the visit before LTFU was 0.72 (20/105) which worsened on return [1.04 (20/219), p<0.001) and remained worse at all timepoints after return: 0.92 (20/166) at 3 months (p<0.001), 0.97 (20/187) at 6 months (p<0.001), 0.94 (20/174) at 12 months (p<0.001) and 1.01 (20/205) at final visit (p<0.001). Mean central foveal thickness (CFT) increased from 252 µm at the visit before LTFU to 396 µm at the return visit (p<0.001). No difference in CFT was noted by 3 months (258 µm, p=0.71), 6 months (241 µm, p=0.54) or 12 months after return (250 µm, p=0.95). CFT was thinner at the final visit (215 µm, p=0.018). CONCLUSION: RVO patients receiving anti-VEGF injections who were LTFU experienced a decline in VA that did not return to the levels seen before LTFU despite improvement in CFT after restarting therapy, underscoring the importance of ongoing treatment.

Resolution of Pseudophakic Cystoid Macular Edema: 2 mg Intravitreal Triamcinolone Acetonide versus 40 mg Posterior Sub-Tenon Triamcinolone Acetonide.

PURPOSE: To compare 2 mg intravitreal triamcinolone (IVT) versus 40 mg posterior sub-Tenon triamcinolone acetonide (STT) for the treatment of eyes with pseudophakic cystoid macular edema. METHODS: A retrospective, single-center review of eyes receiving 2 mg IVT between 3/1/2012-3/1/2017 and 40 mg STT between 1/1/2015-3/1/2017. Visual acuity (VA) and central macular thickness (CMT) were recorded at baseline, 1-, 3-, and 6-month follow-up visits. RESULTS: Forty-five eyes were included in the IVT group and 50 eyes in the STT group. Change in VA from baseline to 1, 3, and 6 months was not significantly different between IVT and STT (6 months: 2.3 lines vs. 2.4 lines, p = .10). The IVT group achieved significantly better CMT improvement from baseline compared to STT at 1 month (255 µm vs. 187 µm; p = .03), but this difference was not present at month 3 (214 µm vs. 212 µm; p = .79) or month 6 (176 µm vs. 207 µm; p = .29). During the 6-month follow-up period, approximately 7% of eyes in the IVT group and 12% of eyes in the STT group developed ocular hypertension (p = .43), and all cases were successfully managed with topical anti-ocular hypertensive therapy or observation. CONCLUSIONS: 2 mg IVT and 40 mg STT both achieved significant improvement in vision and CMT with no significant difference between interventions at 3- and 6-month follow-up.

Endophthalmitis after Cataract Surgery: Changes in Management Based on Microbiologic Cultures.

PURPOSE: To assess the utility of microbiologic culture data for the management of endophthalmitis after cataract surgery. DESIGN: Retrospective, single-center, cohort study. PARTICIPANTS: All patients treated for endophthalmitis after cataract surgery between January 1, 2014, and December 31, 2017, at a single institution. METHODS: Endophthalmitis cases were determined from billing records and confirmed with chart review. A change in clinical management was defined as additional intravitreal antibiotic injections or pars plana vitrectomy. MAIN OUTCOME MEASURES: A change in clinical management within 2 weeks of initial endophthalmitis culture and treatment; visual acuity (VA). RESULTS: A total of 111 eyes of 111 patients were treated for endophthalmitis after cataract surgery, of which 57 (51%) were culture-positive. After initial treatment of endophthalmitis, a change in clinical management after vitreous culture occurred in 9 of 111 eyes (8%), including 6 of 57 (11%) culture-positive eyes compared with 3 of 54 (6%) culture-negative eyes (P = 0.49). Change in clinical management for culture-positive eyes was based on declining vision (3 eyes), worsening clinical examination results (2 eyes), and retinal detachment (1 case). Change in clinical management for culture-negative endophthalmitis eyes was based on worsening clinical examination results (2 eyes) and declining vision (1 eye). No additional interventions were initiated on the basis of positive culture results. At final follow-up, mean logarithm of the minimum angle of resolution (logMAR) VA was 1.09 (∼20/250) for the culture-positive eyes compared with 0.59 (∼20/80) for culture-negative eyes (adjusted difference, 0.394; 95% confidence interval, 0.02-0.77, P = 0.03). Rhegmatogenous retinal detachments (RRDs) or retinal tears occurred in 19 of 111 eyes (17%) after developing endophthalmitis, and culture-positive eyes developed a secondary RRD in 11 of 57 eyes (19%) compared with 3 of 54 (6%) culture-negative eyes (P = 0.03). CONCLUSIONS: After endophthalmitis related to cataract surgery, vitreous cultures may have prognostic value for final visual outcomes but have a limited effect on clinical management.

The Impact of Physician Face Mask Use on Endophthalmitis After Intravitreal Anti-Vascular Endothelial Growth Factor Injections.

PURPOSE: To evaluate the effect of physician face mask use on rates and outcomes of postinjection endophthalmitis. DESIGN: Retrospective, comparative cohort study. METHODS: Setting: Single-center. StudyPopulation: Eyes receiving intravitreal anti-vascular endothelial growth factor injections from July 1, 2013, to September 1, 2019. INTERVENTION: Cases were divided into "Face Mask" group if face masks were worn by the physician during intravitreal injections or "No Talking" group if no face mask was worn but a no-talking policy was observed during intravitreal injections. MainOutcomeMeasures: Rate of endophthalmitis, visual acuity, and microbial spectrum. RESULTS: Of 483,622 intravitreal injections administered, 168 out of 453,460 (0.0371%) cases of endophthalmitis occurred in the No Talking group, and 9 out of 30,162 (0.0298%) cases occurred in the Face Mask group (odds ratio, 0.81; 95% confidence interval, 0.41-1.57; P = .527). Sixteen cases of oral flora-associated endophthalmitis were found in the No Talking group (1 in 28,341 injections), compared to none in the Face Mask group (P = .302). Mean logMAR visual acuity at presentation in cases that developed culture-positive endophthalmitis was significantly worse in the No Talking group compared to the Face Mask group (17.1 lines lost from baseline acuity vs 13.4 lines lost; P = .031), though no difference was observed at 6 months after treatment (P = .479). CONCLUSION: Physician face mask use did not influence the risk of postinjection endophthalmitis compared to a no-talking policy. However, no cases of oral flora-associated endophthalmitis occurred in the Face Mask group. Future studies are warranted to assess the role of face mask use to reduce endophthalmitis risk, particularly attributable to oral flora.

Effect of Adjuvant Topical Dorzolamide-Timolol vs Placebo in Neovascular Age-Related Macular Degeneration: A Randomized Clinical Trial.

Importance: Some eyes with neovascular age-related macular degeneration (AMD) have persistent exudation despite frequent intravitreal anti-vascular endothelial growth factor (VEGF) injections. Adjuvant therapies that further reduce edema may improve vision outcomes. Objective: To compare the short-term effect of topical dorzolamide-timolol vs placebo in eyes with neovascular AMD that have persistent exudation following intravitreal anti-VEGF injections. Design, Setting, and Participants: Randomized placebo-controlled clinical trial with enrollment from March 1, 2017, through October 30, 2018. Multicenter trial at 4 clinical sites in the United States. Sixty-three patients with neovascular AMD who had persistent exudation despite intravitreal anti-VEGF injections at 4-week, 5-week, or 6-week intervals. Interventions: Patients were randomized to use dorzolamide-timolol or artificial tears for the study duration. They continued to receive the same anti-VEGF drug at the same interval as the 2 visits before enrollment for 3 additional study visits. Main Outcomes and Measures: The primary outcome measure was change in mean central subfield thickness on optical coherence tomography from baseline to visit 3 (approximately 3 months). Secondary measures included change in mean maximum subretinal fluid height, mean maximum pigment epithelial detachment height, and mean visual acuity (VA). Results: This trial included 52 patients. All 27 patients (100%) assigned to dorzolamide-timolol and 23 of 25 (92%) assigned to placebo were analyzed for the primary outcome. Mean (SD) age was 78.4 (7) years, and 34 of 50 patients (68%) were women. Mean (SD) injections were 20.5 (14) (range, 4-58) before enrollment. Mean (SD) baseline logMAR VA was 0.361 (0.26) (approximate Snellen equivalent, 20/50). Comparing the dorzolamide-timolol with placebo group from baseline to visit 3, mean (SD) change in central subfield thickness (primary outcome) was -36.6 (54) µm vs 1.7 (52.3) µm (difference, 30.8; 95% CI, 0.3-61.3; P = .04); secondary outcomes: maximum PED height was -39.1 (65) µm vs 1.1 (16) µm (difference, 39.6; 95% CI, 9.6-69.6; P = .01) and change in VA from baseline to visit 3 was -2.3 (5) vs 0.3 (1) letters (difference, 2.6 letters; 95% CI, -1.9 to 7.1 letters; P = .78). Conclusions and Relevance: These findings suggest use of dorzolamide-timolol in patients with neovascular AMD with persistent exudation resulted in anatomic but not visual acuity improvements compared with placebo at approximately 3 months. Additional clinical trials with longer follow-up and larger sample sizes presumably would be needed to determine the role, if any, of dorzolamide-timolol in neovascular AMD. Trial Registration: ClinicalTrials.gov Identifier: NCT03034772.

Changes in Management Based on Vitreous Culture in Endophthalmitis After Intravitreal Anti-vascular Endothelial Growth Factor Injection.

PURPOSE: To assess whether vitreous culture results affect the clinical management of patients with acute endophthalmitis after intravitreal anti-vascular endothelial growth factor (VEGF) injection. DESIGN: Retrospective case series. METHODS: Setting: Single-center. STUDY POPULATION: Patients who developed endophthalmitis after intravitreal injection of aflibercept, bevacizumab, or ranibizumab between January 1, 2016, and May 31, 2018. OBSERVATION: A change in clinical management was defined as additional intravitreal antibiotic injections or pars plana vitrectomy. MAIN OUTCOME MEASURES: A change in clinical management within 2 weeks of initial endophthalmitis culture and treatment; visual acuity. RESULTS: Of 204,986 intravitreal anti-VEGF injections performed, 60 cases (0.0293%) of endophthalmitis were identified, 18 of which were culture-positive. Six of 60 eyes (10%) had a change in clinical management. A change in clinical management was initiated in 3 of 18 (17%) culture-positive cases compared to 3 of 42 (7%) culture-negative cases (P = .357). Changes in management for culture-positive cases were performed based on declining vision (2 cases) and worsening clinical examination (1 case). Changes in management for culture-negative endophthalmitis cases were performed based on declining vision (1 case) and worsening clinical examination (2 cases). No additional interventions were initiated based on positive-culture results. Comparing vision loss from baseline by culture result, at final follow-up, oral flora-associated culture-positive cases lost 17.5 lines, non-oral flora-associated culture-positive cases lost 9.1 lines, and culture-negative cases lost 2.5 lines of vision (P < .001). CONCLUSION: Following endophthalmitis from intravitreal injection of anti-VEGF agents, vitreous culture data may help prognosticate visual outcomes but appear to have a limited effect on clinical management.

Intravitreal Anti-Vascular Endothelial Growth Factor Injections for Macular Edema Associated With Central Retinal Vein Occlusion in Patients Age 40 Years or Younger.

BACKGROUND AND OBJECTIVE: To determine the efficacy of anti-vascular endothelial growth factor (VEGF) therapy for macular edema due to central retinal vein occlusion (CRVO) in younger adults. PATIENTS AND METHODS: The outcomes of CRVO patients age 40 years or younger with baseline logarithm of the minimum angle of resolution (logMAR) visual acuity (VA) between 1.30 (20/400 Snellen equivalent) and 0.30 (20/40 Snellen equivalent) and central retinal thickness (CRT) greater than 250 µm were reviewed. VA and CRT were measured at baseline and months 1, 3, 6, and 12. RESULTS: Seventeen eyes of 17 young CRVO patients were included in this study. The logMAR VA improved significantly from 0.64 (20/87 Snellen equivalent) to 0.14 (20/28 Snellen equivalent) 12 months following treatments (P < .001). The CRT decreased from 619 µm ± 238 µm at baseline to 290 µm ± 34 µm at 12 months (P < .001). CONCLUSION: Anti-VEGF injections appear to be effective for macular edema regression and vision improvement in younger adults with CRVO over 12 months of follow-up.

Determining the effect of low-dose isotretinoin on proliferative vitreoretinopathy: the DELIVER trial.

PURPOSE: To examine the effect of low-dose, oral isotretinoin in lowering the risk of proliferative vitreoretinopathy (PVR) following rhegmatogenous retinal detachment (RRD) repair. METHODS: Prospective, open label, dual-cohort study with pathology-matched historical controls. The prospective experimental arms included two cohorts, composed of 51 eyes with recurrent PVR-related RRD and 58 eyes with primary RRD associated with high-risk features for developing PVR. Eyes in the experimental arms received 20 mg of isotretinoin by mouth once daily for 12 weeks starting the day after surgical repair. The primary outcome measure was single surgery anatomical success rate at 3 months following the study surgery. RESULTS: The single surgery anatomic success rate was 78.4% versus 70.0% (p=0.358) in eyes with recurrent PVR-related retinal detachment exposed to isotretinoin versus historical controls, respectively. In eyes with RRD at high risk for developing PVR, the single surgery success rate was 84.5% versus 61.1% (p=0.005) for eyes exposed to isotretinoin versus historical controls, respectively. For eyes enrolled in the experimental arms, the most common isotretinoin-related side effects were dry skin/mucus membranes in 106 patients (97.2%), abnormal sleep/dreams in 4 patients (3.7%) and fatigue in 3 patients (2.8%). CONCLUSION: The management and prevention of PVR is challenging and complex. At the dose and duration given in this study, oral istotretinoin may reduce the risk of PVR-associated recurrent retinal detachment in eyes with primary RRD at high risk of developing PVR.

A RANDOMIZED DOUBLE-BLIND PLACEBO-CONTROL PILOT STUDY OF EPLERENONE FOR THE TREATMENT OF CENTRAL SEROUS CHORIORETINOPATHY (ECSELSIOR).

PURPOSE: To evaluate the safety and effects of oral eplerenone in chronic central serous chorioretinopathy. METHODS: Prospective, randomized, double-blind, placebo-control study at a tertiary referral academic private practice. For a diagnosis of chronic central serous chorioretinopathy, patients must have had at least 3 months clinical follow-up demonstrating persistent symptoms, subfoveal fluid on spectral-domain optical coherence tomography, and <50% reduction in fluid thickness. Patients were randomized 2:1 (treatment:placebo) to receive eplerenone (25 mg daily for 1 week, then up to 50 mg daily for 8 weeks) or placebo once daily. RESULTS: Fifteen patients completed the study. Ten patients (15 eyes) were randomized into the eplerenone treatment arm, while the remaining 5 patients (6 eyes) received placebo. After 9 weeks of eplerenone therapy, mean logarithm of the minimal angle of resolution visual acuity improved from 0.394 (Snellen equivalent: 20/50) to 0.330 (20/43, P = 0.04). In the placebo group, the mean logarithm of the minimal angle of resolution visual acuity slightly decreased from 0.313 (20/41) to 0.342 (20/44) during the same period (P = 0.21). With respect to anatomic changes, mean maximal subretinal fluid height in the eplerenone group improved from 139.3 µm at baseline to 51.8 µm (P = 0.02), mean subfoveal fluid height improved from 121.4 µm to 29.4 µm (P = 0.01), and mean central subfield thickness improved from 366.2 µm to 283.7 µm (P = 0.02). In comparison with the placebo group, mean maximal subretinal fluid height worsened from 135.9 µm to 172.3 µm (P = 0.32), mean subfoveal fluid height worsened from 92.1 µm to 134.0 µm (P = 0.54), and mean central subfield thickness worsened from 345.0 µm to 380.0 µm (P = 0.37). No patients in either group experienced serious adverse events to result in treatment discontinuation. CONCLUSION: These findings suggest that oral eplerenone therapy is safe and potentially effective in the treatment of chronic central serous chorioretinopathy with persistent subretinal fluid.

Alternating Bi-Weekly Intravitreal Ranibizumab and Bevacizumab for Refractory Neovascular Age-Related Macular Degeneration with Pigment Epithelial Detachment.

OBJECTIVE: To describe visual and anatomical outcomes following bi-weekly intravitreal ranibizumab/bevacizumab injections in eyes with refractory neovascular age-related macular degeneration (AMD) and pigment epithelial detachment (PED). DESIGN: Retrospective, consecutive, interventional case series. PARTICIPANTS: Eighteen patients diagnosed with neovascular AMD that were refractory to anti-VEGF therapy and received alternating biweekly ranibizumab/bevacizumab injections were included. METHODS: Patients with neovascular AMD and PED that were refractory to at least 11 monthly ranibizumab or bevacizumab injections were included in this study at a large, single retina practice. Following inclusion, patients received four bi-weekly alternating ranibizumab/bevacizumab intravitreal injections. After completing a course of four bi-weekly injections, patients were treated with variable regimens of intravitreal anti-vascular endothelial growth factor (VEGF) therapy. The primary outcomes of the study included change in visual acuity (VA) and central foveal thickness (CFT) at eight weeks follow-up. RESULTS: Study eyes had previously received a mean of 22 intravitreal anti-VEGF injections. At enrollment, mean VA was 20/95 and mean CFT was 455 µm. After four bi-weekly anti-VEGF injections, mean VA improved to 20/65 (p < 0.001), and mean CFT decreased to 387 µm (p = 0.029). In patients with PED, there was a mean 27.9% reduction in height (p = 0.046) at eight weeks' follow-up. CONCLUSIONS: Four injections of bi-weekly alternating ranibizumab/bevacizumab improved visual acuity and reduced macular thickness in a number of patients with refractory neovascular AMD and PED.

Effect of a Strict 'No-Talking' Policy During Intravitreal Injection on Post-Injection Endophthalmitis.

BACKGROUND AND OBJECTIVE: To report the effect of a "no-talking" policy during intravitreal injection (IVI) on post-injection endophthalmitis. PATIENTS AND METHODS: Retrospective, comparative, consecutive case series of patients receiving IVI between Jan. 1, 2009, and Dec. 31, 2012. A 24-month "usual care" period was compared to a 24-month no-talking period, during which a strategy to further minimize speech during IVI was implemented. RESULTS: During the usual care period, 47,155 IVIs were performed, with nine culture-positive cases (0.019%), including seven due to oral pathogens (0.015%). During the no-talking period, 82,658 IVIs were performed, with eight culture-positive cases (0.010%), including two due to oral pathogens (0.002%). The no-talking policy was associated with a decreased endophthalmitis risk (P = .004), including oral pathogen-associated endophthalmitis (P = .02). CONCLUSION: This study demonstrates that a more stringent no-talking policy during IVI may reduce the risk of post-injection endophthalmitis.

Oral eplerenone for treatment of chronic central serous chorioretinopathy: a case series.

BACKGROUND AND OBJECTIVE: To evaluate the effect of oral eplerenone on subretinal fluid, visual acuity, and choroidal thickness in patients with chronic central serous chorioretinopathy (CSCR). PATIENTS AND METHODS: Retrospective review of all patients (14 eyes of 14 patients) monitored for a minimum of 3 months with chronic CSCR who were treated with oral eplerenone in a single multi-physician retina practice. Visual acuity, dilated funduscopic examination, and spectral-domain ocular coherence tomography (OCT) with enhanced depth imaging (EDI) were obtained at each visit. Measurement of subfoveal fluid (SFF) height and choroidal thickness were performed. Two-tailed paired t test was used to calculate statistical significance of pre- and post-treatment variables. RESULTS: At 1 month, 10 of 14 eyes had decreased SFF height on OCT and two eyes had complete resolution of SFF. Mean SFF height decreased from 130 µm to 62 µm (P = .05). Mean choroidal thickness decreased from 315 µm to 282 µm (P = .07). Mean visual acuity improved from logMAR 0.41 to 0.40. At 3 months, 13 of 14 (93%) had decreased SFF on OCT, and nine eyes (64%) had complete resolution of SFF. Mean SFF height decreased to 21 µm (P = .004). Mean choroidal thickness decreased to 253 µm (P = .10). Mean visual acuity improved to logMAR 0.28 (P = .02). CONCLUSION: Oral eplerenone may be effective in treating patients with chronic CSCR.
