Purpose: To evaluate safety and tolerability of EYP-1901, an intravitreal insert containing vorolanib, a pan-VEGF receptor inhibitor packaged in a bioerodible delivery technology (Durasert E™) for sustained delivery, in patients with wet age-related macular degeneration (wAMD) previously treated with anti-VEGF therapy., Design: Phase I, multicenter, prospective, open-label, dose-escalation trial., Participants: Patients with wAMD and evidence of prior anti-VEGF therapy response., Methods: Patients received a single intravitreal injection of EYP-1901., Main Outcome Measures: The primary objective was to evaluate safety and tolerability of EYP-1901. Secondary objectives assessed biologic activity of EYP-1901 including best-corrected visual acuity (BCVA) and central subfield thickness (CST). Exploratory analyses included reduction in anti-VEGF treatment burden and supplemental injection-free rates., Results: Seventeen patients enrolled in the 440 μg (3 patients), 1030 μg (1 patient), 2060 μg (8 patients), and 3090 μg (5 patients) dose cohorts. No dose-limiting toxicity, ocular serious adverse events (AEs), or systemic AEs related to EYP-1901 were observed. There was no evidence of ocular or systemic toxicity related to vorolanib or the delivery technology. Moderate ocular treatment-emergent AEs (TEAEs) included reduced visual acuity (2/17) and retinal exudates (3/17). One patient with reduced BCVA had 3 separate reductions of 17, 18, and 16 letters, and another had a single drop of 25 letters. One severe TEAE, neovascular AMD (i.e., worsening/progressive disease activity), was reported in 1 of 17 study eyes but deemed unrelated to treatment. Mean change from baseline in BCVA was -1.8 letters and -5.4 letters at 6 and 12 months. Mean change from baseline in CST was +1.7 μm and +2.4 μm at 6 and 12 months. Reduction in treatment burden was 74% and 71% at 6 and 12 months. Of 16 study eyes, 13, 8, and 5 were injection-free up to 3, 6, and 12 months., Conclusion: In the DAVIO trial (ClinicalTrials.gov identifier, NCT04747197), EYP-1901 had a favorable safety profile and was well tolerated in previously treated eyes with wAMD. Measures of biologic activity remained relatively stable following a single EYP-1901 injection. These preliminary data support ongoing phase II and planned phase III trials to assess efficacy and safety., Financial Disclosures: The author(s) have no proprietary or commercial interest in any materials discussed in this article., (© 2024 by the American Academy of Ophthalmology.)

Purpose of Review: The aim of this study was to update visual outcomes, microbial spectrum and complications in eyes with endophthalmitis following cataract surgery., Recent Findings: A single-institution, retrospective review of eyes treated for endophthalmitis following cataract surgery between 2 January 2014 and 10 January 2017. This study included 112 cases of endophthalmitis following cataract surgery, 58 of which were culture-positive (51.8%). The most isolated organisms were coagulase-negative Staphylococci (56.9%). Oral flora were present in 17.2% of cases. At 6 months, 71.7% of patients achieved visual acuity of at least 20/200 and 51.7% achieved at least 20/40 or better. Visual acuity was better in culture-negative vs. culture-positive cases (∼20/290 vs. ∼20/80, P   =  0.03), and in nonoral flora-associated vs. oral flora-associated culture-positive cases (∼CF vs. ∼20/150, P   <  0.01)., Summary: Following postcataract surgery endophthalmitis, approximately 70% of eyes achieved vision of 20/200 or better and half achieved vision of 20/40 or better 6 months after treatment. Poor visual outcomes were seen in eyes with positive bacterial cultures and with oral flora., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Purpose: To compare the incidence and visual outcomes of endophthalmitis after injection of an intravitreal dexamethasone implant and injection of intravitreal ranibizumab., Methods: This retrospective cohort study assessed endophthalmitis in eyes receiving an intravitreal injection of a 0.7 mg dexamethasone implant (DEX group), 0.5 mg ranibizumab (R5 group), or 0.3 mg ranibizumab (R3 group) between January 1, 2016, and May 31, 2018, at 2 large retina practices in the United States., Results: Suspected endophthalmitis occurred in 5 eyes after 4973 DEX injections, 43 eyes after 163 974 R5 injections, and 6 eyes after 18 954 R3 injections. Suspected endophthalmitis was significantly more common in the DEX group (1/995) than in the R5 group (1/3813) ( P  = .008) but not than in the R3 group (1/3159) ( P  = .10). Visual acuity outcomes were similar in the 3 groups., Conclusions: Suspected endophthalmitis might be more common after 0.7 mg dexamethasone injections than after 0.5 mg ranibizumab injections. Culture-positive endophthalmitis rates were similar across all 3 medications., Competing Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: All authors declare no support from any organization for the submitted work.

Purpose: Routine use of face masks for patients and physicians during intravitreal anti-vascular endothelial growth factor (VEGF) injections has increased with the emergence of the coronavirus disease 2019 pandemic. This study evaluates the impact of universal face mask use on rates and outcomes of post-injection endophthalmitis (PIE)., Design: Retrospective, multicenter, comparative cohort study., Participants: Eyes receiving intravitreal anti-VEGF injections from October 1, 2019, to July 31, 2020, at 12 centers., Methods: Cases were divided into a "no face mask" group if no face masks were worn by the physician or patient during intravitreal injections or a "universal face mask" group if face masks were worn by the physician, ancillary staff, and patient during intravitreal injections., Main Outcome Measures: Rate of endophthalmitis, microbial spectrum, and visual acuity (VA)., Results: Of 505 968 intravitreal injections administered in 110 547 eyes, 85 of 294 514 (0.0289%; 1 in 3464 injections) cases of presumed endophthalmitis occurred in the "no face mask" group, and 45 of 211 454 (0.0213%; 1 in 4699) cases occurred in the "universal face mask" group (odds ratio [OR], 0.74; 95% confidence interval [CI], 0.51-1.18; P = 0.097). In the "no face mask" group, there were 27 cases (0.0092%; 1 in 10 908 injections) of culture-positive endophthalmitis compared with 9 cases (0.004%; 1 in 23 494) in the "universal face mask" group (OR, 0.46; 95% CI, 0.22-0.99; P = 0.041). Three cases of oral flora-associated endophthalmitis occurred in the "no face mask" group (0.001%; 1 in 98 171 injections) compared with 1 (0.0005%; 1 in 211 454) in the "universal face mask" group (P = 0.645). Patients presented a mean (range) 4.9 (1-30) days after the causative injection, and mean logarithm of the minimum angle of resolution (logMAR) VA at endophthalmitis presentation was 2.04 (~20/2200) for "no face mask" group compared with 1.65 (~20/900) for the "universal face mask" group (P = 0.022), although no difference was observed 3 months after treatment (P = 0.764)., Conclusions: In a large, multicenter, retrospective study, physician and patient face mask use during intravitreal anti-VEGF injections did not alter the risk of presumed acute-onset bacterial endophthalmitis, but there was a reduced rate of culture-positive endophthalmitis. Three months after presentation, there was no difference in VA between the groups., (Copyright © 2021 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.)

Aims : To evaluate whether the incidence, microbial spectrum, and visual outcomes of endophthalmitis following intravitreal injections have changed over time. Methods : Retrospective cohort study of endophthalmitis in eyes receiving intravitreal injection of anti-vascular endothelial growth factor between 2009-2012 and 2016-2017 at a single, large retina practice. Results : A total of 283,315 injections resulted in 96 suspected infectious endophthalmitis cases. Comparing 2009-2012 and 2016-2017, the rate of suspected endophthalmitis changed from 1 in 2,663 injections to 1 in 3,195 injections ( p = .37). Visual outcomes 6 months after endophthalmitis were significantly better during the latter period ( p = .04), with an average loss of 6.3 lines of VA in 2009-2012 compared to a loss of 3.6 lines in 2016-2017. In multivariate analysis, a "no-talking" policy during injections resulted in a trend towards a decrease in endophthalmitis incidence ( p = .08). Cessation of post-injection topical antibiotic use did not independently decrease endophthalmitis incidence ( p = .24) when the effect of a "no-talking" policy was taken into account. A lower rate of endophthalmitis was seen after prefilled vs. conventionally prepared ranibizumab syringe use for injection (0.014% vs. 0.035%, respectively), though this difference did not meet statistical significance ( p = .16). Conclusion : The incidence of endophthalmitis after intravitreal injection decreased and visual outcomes improved between the periods of 2009-2012 and 2016-2017. A "no-talking" policy during injections was associated with a trend toward a decrease in endophthalmitis rate.

Purpose: Visual outcomes after postinjection endophthalmitis have been well-studied, but the effect of endophthalmitis on the underlying exudative disease process remains unclear. We investigate the need for continued anti-vascular endothelial growth factor injections after endophthalmitis., Methods: Eyes that developed endophthalmitis after intravitreal injection of anti-vascular endothelial growth factor between January 1, 2016, and May 31, 2018, at a single academic retina practice were identified. Retrospective chart review was performed to determine 1) the proportion of eyes without recurrence of macular edema or subretinal fluid after endophthalmitis and 2) the proportion achieving a 12-week or greater interval between anti-vascular endothelial growth factor injections or exudation after endophthalmitis compared with internal controls before endophthalmitis., Results: Of 50 eyes with endophthalmitis, seven (14.0%) had no fluid recurrence at a mean of 98.1 week. Of 43 eyes with recurrence, 48.0% achieved a >12-week recurrence-free interval after endophthalmitis (vs. 8.3% before endophthalmitis; P < 0.0001). Eyes with compared to those without choroidal neovascularization were more likely to achieve this interval (60.5% vs. 8.3%, respectively; P = 0.002)., Conclusion: Endophthalmitis after anti-vascular endothelial growth factor injection is associated with relative stability of the underlying exudation. Further research is necessary to elucidate the mechanism, which may be useful in developing strategies and targets for the treatment of exudative macular diseases.

Background and Objective: To evaluate the impact of systemic immunosuppressive therapy on the rates and outcomes of endophthalmitis following intravitreal anti-vascular endothelial growth factor (VEGF) injections., Patients and Methods: A retrospective, single-center, comparative cohort study examining eyes undergoing intravitreal anti-VEGF injections from January 2016 to September 2019. Cohorts were created based on concurrent immunosuppressive therapy at time of injection., Results: Of 270,347 anti-VEGF injections administered, 1,300 injections (0.48%) were administered while on systemic immunosuppressive therapy. The odds of endophthalmitis occurring in the immunosuppression group was 9.86 (95% confidence interval [CI], 4.0-24.3; P < .001) times higher than the no-immunosuppression group. Symptom onset occurred 2.51 (95% CI, 0.15-4.870; P = .040) days earlier in the immunosuppression cohort; visual acuity at 6 months after treatment was similar in both groups., Conclusions: Patients on systemic immunosuppressive medications undergoing intravitreal injections may be at increased risk for post-injection endophthalmitis and may have earlier symptom onset. However, visual outcomes were similar between the two groups. [ Ophthalmic Surg Lasers Imaging Retina . 2021;52:S17-S22.] .

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.

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., (Copyright © 2020.

Objective: To compare rates of ocular hypertension (OHT) in eyes receiving 40 mg sub-Tenon triamcinolone (STT), 0.7 mg dexamethasone implant (DEX), and 2 mg intravitreal triamcinolone (IVT)., Methods: This study is a single-centre, retrospective case series. All patients receiving STT and DEX between 4/1/2014 and 3/1/2017 and IVT between 3/1/2012 and 3/1/2017 with a minimum of 3 months' follow-up were included. OHT was defined as an intraocular pressure (IOP) >24 mm Hg. Patients receiving any other form of topical, oral, or intravitreal steroid were excluded., Results: 113 eyes from 104 patients in the STT group, 122 eyes from 109 patients in the DEX group, and 109 eyes from 103 patients in the IVT group were included. The mean number of injections for each eye was 1.7 in the STT group, 2.6 for the DEX group, and 2.8 for the IVT group (p < 0.001). Twenty eyes (17.7%) developed OHT in the STT group, 19 eyes (15.6%) developed OHT in the DEX group, and 14 eyes (12.8%) developed OHT in the IVT group (p = 0.60). IOP was controlled in all eyes with observation, topical IOP-lowering medication, or surgical intervention. The rate of incisional glaucoma surgery was 1.7% in the STT group, 1.6% in the DEX group, and 0% in the IVT group (p = 0.55)., Conclusions: The rate of OHT was similar across treatment groups. The proportion of OHT in patients with a history of glaucoma was no different from that in patients without a history of glaucoma. All cases were successfully managed with observation, medical treatment, or incisional surgery., (Copyright © 2020 Canadian Ophthalmological Society. Published by Elsevier Inc. All rights reserved.)

Although intravitreal injections of anti-vascular endothelial growth factor medications are generally safe and effective, endophthalmitis remains a rare but potentially devastating complication. This review evaluates recent evidence for prophylactic strategies to prevent postinjection endophthalmitis. Povidone-iodine applied to the ocular surface before injection remains the most effective technique to prevent infection although aqueous chlorhexidine may be an acceptable alternative. Minimizing oral flora exposure, particularly with a no-talking policy, has been shown to reduce endophthalmitis rates. Recent studies of prefilled syringes suggest that the technology significantly lowers the risk of injection, likely by eliminating the transfer of medication from a storage vial to a syringe. Avoiding lid or lash touch during the injection process is an important tool to decrease patient risk, although this may be accomplished with manual lid retraction rather than a lid speculum. Same-day bilateral intravitreal injections have been shown to be safe. Several other strategies have not shown efficacy. The use of drapes or gloves, the clinical setting of injection administration, and ocular location of injection do not appear to affect infection rates. Topical prophylactic antibiotics do not reduce the risk of endophthalmitis and should not be routinely used., (Copyright © 2020 Canadian Ophthalmological Society. Published by Elsevier Inc.

Purpose: This article compares 2-mg intravitreal triamcinolone (IVT) and 0.7-mg dexamethasone (DEX) implant for the treatment of diabetic macular edema in eyes that had a suboptimal response to antivascular endothelial growth factor therapy., Methods: A single-center, retrospective review was conducted of patients receiving either IVT between January 1, 2013, and January 1, 2018, or patients receiving DEX between October 1, 2015, and January 1, 2018. Visual acuity and central macular thickness (CMT) were recorded at visit of first injection and all subsequent visits., Results: Twenty-five eyes were included in the DEX group and 32 eyes were included in the IVT group. Change in vision from baseline was similar between DEX and IVT at 6-month follow-up (1.1 lines vs 2.3 lines, respectively; P = .24). Mean decrease in CMT from baseline was not different at 6-month follow-up (DEX: 120 µm vs IVT: 185 µm; P = .17)., Conclusions: DEX and 2-mg IVT both achieved improvement in vision and CMT with no significant differences between treatment groups at 6-month follow-up., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2020.)

Background : To compare the incidence and outcomes of ocular hypertension (OHT) after intravitreal injection of 0.7 mg dexamethasone (DEX) and 2 mg triamcinolone acetonide (IVT). Methods : In a single-center, retrospective comparative case series, all patients with at least 3 months follow-up receiving 2 mg IVT 3/1/2012 - 3/1/2017 or 0.7 mg dexamethasone 10/1/2014 - 3/1/2017 were included. Ocular hypertension was defined as an intraocular pressure (IOP) ≥ 25 mmHg. Patients with a minimum of 3 months follow-up were included. Patients receiving any other form of topical, oral, or intravitreal steroid were excluded. Results : 106 eyes in 100 patients receiving IVT and 114 eyes in 102 patients receiving DEX were included. The mean number of injections was 2.9 for patients receiving IVT and 2.4 for patients receiving DEX ( p = .11). Fourteen eyes (13.2%) in 14 patients receiving IVT developed OHT compared to 17 eyes (15.1%) in 15 patients receiving DEX ( p = .85). All cases of OHT were managed with IOP lowering drops or observation alone. Conclusions : Rates of ocular hypertension following 2 mg IVT and DEX are similar. All patients developing OHT were successfully managed without surgical intervention.

Purpose: To report the incidence and course of ocular hypertension after intravitreal injection of 2-mg triamcinolone acetonide (IVT)., Methods: In a retrospective, consecutive series, all patients receiving 2-mg IVT at a single institution between March 1, 2012, and March 1, 2017, with a minimum of 3-month follow-up were reviewed. Ocular hypertension was defined as an intraocular pressure (IOP) measurement over 24 mmHg at any follow-up visit after IVT. Patients receiving topical, periocular, or intravitreal corticosteroid other than 2-mg IVT were excluded., Results: A total of 106 eyes in 100 patients receiving at least one injection of 2-mg IVT were included. Eyes received an average of 2.9 injections (range 1-17), and average patient follow-up was 15.1 months (range 3.0-52.5 months). A total of 14 eyes (13.2%) in 14 patients developed ocular hypertension after a median of 1.5 injections (range 1-9) with an average peak IOP of 29 mmHg (range 25-38 mmHg). Overall, a total of 11 eyes (10.4%) had an IOP elevation ≥10 mmHg above baseline at any point after first IVT. In all cases of ocular hypertension, IOP was successfully managed with observation or topical IOP-lowering medication alone; no patients required surgical intervention., Conclusion: Ocular hypertension developed in 13.2% of eyes receiving intravitreal injection of 2-mg triamcinolone acetonide. Incidence of ocular hypertension after 2-mg IVT compares favorably with other intravitreally administered corticosteroids.

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., (Copyright © 2019 Elsevier Inc.

Purpose: To determine long-term visual outcomes in patients who developed endophthalmitis after intravitreal anti-vascular endothelial growth factor injections and to correlate visual outcomes with clinical features., Methods: This is a retrospective, multicenter, consecutive case series of patients diagnosed with anti-vascular endothelial growth factor injection-related endophthalmitis who were treated at Mid Atlantic Retina, the Retina Service of Wills Eye Hospital, Philadelphia, PA, and the University of Southern California Roski Eye Institute, Los Angeles, CA. Patients were included if they had at least 1 year of follow-up. Primary outcome was to evaluate long-term visual outcomes up to 5 years of follow-up. The secondary outcome was to determine clinical features (e.g., culture results) that may predict long-term visual acuity outcomes., Results: A total of 56 cases of endophthalmitis from 168,247 anti-vascular endothelial growth factor injections were identified (0.033%, 1/3,004 injections), from which 51 eyes met inclusion criteria. Mean follow-up period was 3.3 years (median 4 years; range 1-5 years). A total of 24 patients (47%) reached a maximum final follow-up of 5 years. Mean Snellen visual acuity at the causative injection visit was 20/102 and decreased to counting fingers at diagnosis (P < 0.001). At 6-month follow-up, mean visual acuity improved to 20/644 (P < 0.001) and remained stable up to 5 years (20/480, P = 0.003) follow-up compared with diagnosis. At the final follow-up, 20 eyes had visual acuity that returned to within one line of baseline visual acuity (visual recovery group), whereas 31 patients' visual acuity was at least one line worse than initial visual acuity (visual deterioration group). The cultures for the visual recovery group were more likely to grow coagulase-negative Staphylococcus, whereas the visual deterioration group primarily grew Streptococcus species, Staphylococcus aureus, and Enterococcus faecalis (P = 0.002, comparing organisms isolated in the visual recovery and deterioration group)., Conclusion: Visual outcomes after anti-vascular endothelial growth factor injection-related endophthalmitis seem to reach peak improvement by 6 months and remain stable up to a median of 4-year follow-up. Patients who develop culture-negative endophthalmitis or endophthalmitis secondary to coagulase-negative Staphylococcus are more likely to regain baseline visual acuity compared with cases secondary to Streptococcus species.

Purpose: To report the rate, risk factors, and outcomes of rhegmatogenous retinal detachment (RRD) after intravitreal injection of anti-vascular endothelial growth factor medications., Design: Single-center, retrospective, consecutive review., Participants: All patients receiving ranibizumab, bevacizumab, or aflibercept for neovascular age-related macular degeneration or retinal vein occlusion between October 1, 2014, and October 1, 2017., Methods: The total number of eyes and injections were determined from billing codes. Rhegmatogenous retinal detachment patients were determined from billing records and confirmed with chart review., Main Outcome Measures: Rate of retinal detachment and visual acuity outcomes., Results: A total of 180 671 intravitreal injections in 12 718 unique patients were included. An RRD occurred in 24 patients within 3 months after injection, giving a rate of 1 RRD per 7532 intravitreal injections (0.013%) and 1 RRD per 530 patients (0.19%). No association was found between RRD risk after injection and diagnosis (P = 0.54), physician experience (P = 0.23), injection site (P = 0.41), caliper use (P = 0.75), or 31- versus 30-gauge needle use (P = 0.18). A retinal tear was found located in the quadrant of the injection site (within 1.5 clock hours of the injection) in 15 of 24 patients (62.5%; P < 0.0001). At the time of RRD diagnosis, the macula was attached in 9 patients (37.5%). Interventions for RRD repair included pars plana vitrectomy (PPV; 15 patients), combined scleral buckle and PPV (4 patients), pneumatic retinopexy (3 patients), and laser or cryotherapy alone (2 patients). Single-surgery success rate was 54.2%, with 54.5% of recurrent detachments caused by proliferative vitreoretinopathy. Average loss from visual acuity recorded at the visit before diagnosis of RRD was 1.0 line for macula-on detachments versus 6.8 lines for macula-off detachments (P = 0.027) at final follow-up (average, 16.3 months)., Conclusions: Retinal detachment after intravitreal injection is uncommon, with a rate of approximately 1 in 7500 injections. Macular status at the time of RRD diagnosis significantly affects visual outcomes., (Copyright © 2019 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.)

Purpose: To evaluate refractive outcomes after combined pars plana vitrectomy (PPV) and scleral fixation of an intraocular lens (IOL) using Gore-Tex suture., Design: Retrospective cohort study., Participants: Fifty-five eyes from 53 patients who underwent PPV with a Gore-Tex sutured IOL from June 2013 through December 2017., Methods: Patients who underwent combined PPV and scleral fixation of an IOL with Gore-Tex suture were identified. All eyes underwent scleral fixation of either an Akreos A060 or enVista MX60 IOL and were fixated either 2 mm or 3 mm posterior to the limbus. Postoperative manifest refractions were performed at least 3 months after surgery and were compared with preoperative predicted target refraction based on in-the-bag IOL calculations. Subgroup analyses based on sclerotomy placement and IOL models were performed., Main Outcome Measures: Postoperative manifest refraction and difference with sclerotomy placement and IOL model., Results: The mean postoperative spherical equivalent (SEQ) was -0.99±1.00 diopters (D). The mean difference in SEQ (ΔSEQ) from preoperative predicted target was -0.64±1.00 D. The IOL was fixated 2 mm posterior to the limbus in 14 eyes and 3 mm in 41 eyes. Within these 2 subgroups, the mean postoperative SEQ was -1.53±1.35 D for fixation 2 mm posterior to the limbus and -0.82±0.83 D for fixation 3 mm posterior to the limbus (P = 0.09). The mean ΔSEQ was -0.43±0.71 D for fixation 3 mm posterior to the limbus and -1.35±1.32 D for fixation 2 mm posterior to the limbus (P = 0.03). The mean amount of surgically induced astigmatism in the overall cohort was 0.77±0.65 D. The mean ΔSEQ and induced astigmatism were similar between IOL models., Conclusions: After combined PPV and Gore-Tex-sutured IOL implantation, mean postoperative refractive outcomes were more myopic when the IOL was fixated 2 mm from the limbus compared with 3 mm from the limbus. No significant difference was found between IOL models. Based on these results, future implant power calculations may be adjusted to approximate preoperative target refraction more accurately., (Copyright © 2019 American Academy of Ophthalmology.

Purpose: To compare the rates of infectious endophthalmitis following intravitreal injection of ranibizumab using prefilled syringes vs conventional preparation., Design: Multicenter retrospective cohort study., Methods: All eyes receiving intravitreal injection of 0.5 mg ranibizumab for retinal vascular diseases at 10 retina practices across the United States (2016 to 2017) and Japan (2009 to 2017) were included. The total numbers of eyes and injections were determined from billing codes. Endophthalmitis cases were determined from billing records and evaluated with chart review. Primary outcome was the rate of postinjection acute endophthalmitis. Secondary outcomes were visual acuity and microbial spectrum., Results: A total of 243 754 intravitreal 0.5 mg ranibizumab injections (165 347 conventional and 78 407 prefilled) were administered to 43 132 unique patients during the study period. In the conventional ranibizumab group, a total of 43 cases of suspected endophthalmitis occurred (0.026%; 1 in 3845 injections) and 22 cases of culture-positive endophthalmitis occurred (0.013%; 1 in 7516 injections). In the prefilled ranibizumab group, 12 cases of suspected endophthalmitis occurred (0.015%; 1 in 6534 injections) and 2 cases of culture-positive endophthalmitis occurred (0.0026%; 1 in 39 204 injections). Prefilled syringes were associated with a trend toward decreased risk of suspected endophthalmitis (odds ratio 0.59; 95% confidence interval 0.31-1.12; P = .10) and a statistically significant decreased risk of culture-positive endophthalmitis (odds ratio 0.19; 95% confidence interval 0.045-0.82; P = .025). Average logMAR vision loss at final follow-up was significantly worse for eyes that developed endophthalmitis from the conventional ranibizumab preparation compared to the prefilled syringe group (4.45 lines lost from baseline acuity vs 0.38 lines lost; P = .0062). Oral-associated flora was found in 27.3% (6/22) of conventional ranibizumab culture-positive endophthalmitis cases (3 cases of Streptococcus viridans, 3 cases of Enterococcus faecalis) compared to 0 cases in the prefilled ranibizumab group., Conclusion: In a large, multicenter, retrospective study the use of prefilled syringes during intravitreal injection of ranibizumab was associated with a reduced rate of culture-positive endophthalmitis, including from oral flora, as well as with improved visual acuity outcomes., (Copyright © 2018 Elsevier Inc.

Aim: To evaluate whether people with age-related macular degeneration (AMD) and a history of amblyopia have equal severity of AMD in both eyes., Methods: Billing records were used to locate all people with a history of amblyopia and AMD evaluated between 1 January 2003 and 1 June 2015 at a single ophthalmology institute. Two ophthalmic graders blinded to amblyopia status determined the severity of AMD in each eye using fundus photos and a validated grading scale., Results: A total of 14 people were found to have AMD and a documented history of amblyopia. Average patient age was 77.0 years and average best corrected visual acuity was 20/160 in eyes with a history of amblyopia and 20/40 in fellow eyes without amblyopia. Eyes with a history of amblyopia were found to have a lower AMD severity score (mean lower score: -1.38; paired t-test P=0.019). Of the 11 people with asymmetric disease severity, 10 individuals had worse AMD in the non-amblyopic eye while one person had worse AMD in the amblyopic eye (P=0.0067)., Conclusions: Our pilot study suggests that eyes with a history of amblyopia may manifest decreased severity of AMD compared with non-ambylopic eyes in the same patient. Further research is warranted to investigate this clinical observation., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Purpose: To evaluate practice patterns for bilateral same-day intravitreal anti-vascular endothelial growth factor (VEGF) injections and determine the rate of unilateral and bilateral postinjection endophthalmitis after bilateral same-day intravitreal anti-VEGF injections., Design: Retrospective cohort study., Methods: The records of a large academic private practice were electronically queried for all office visits, during which bilateral intravitreal anti-VEGF injections were performed between April 1, 2012 and August 21, 2017 for patients with a diagnosis of neovascular age-related macular degeneration, diabetic macular edema, or retinal vein occlusion. Demographic information and indication for injection were recorded for each patient and office visit. Charts of patients with endophthalmitis were reviewed, and information was collected on presentation examination, culture data, and visual outcomes., Results: During the study period, 101 932 bilateral same-day intravitreal anti-VEGF injections were performed over 50 966 office visits for 5890 patients. The mean (standard deviation) age of patients in this cohort was 74.2 (14.1) years and 60.6% of patients were female. The 2 most common indications for injection were neovascular age-related macular degeneration (54.3% of patients) and diabetic macular edema (35.4% of patients). Twenty-eight cases of endophthalmitis (0.027% of total injections) occurred during the study period. There were no cases of bilateral endophthalmitis, and no patients had more than 1 occurrence of endophthalmitis., Conclusions: In this large cohort of patients undergoing bilateral same-day intravitreal anti-VEGF injections, there were no cases of bilateral endophthalmitis. Additionally, the overall rate of unilateral endophthalmitis was low and comparable to prior studies of unilateral injections. These results support the safety of bilateral same-day intravitreal anti-VEGF treatment., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Purpose: To evaluate visual and anatomical outcomes of diabetic tractional retinal detachment repaired with pars plana vitrectomy., Methods: Operative records were used to retrospectively identify all patients with tractional retinal detachments secondary to proliferative diabetic retinopathy surgically repaired with pars plana vitrectomy between November 1, 2009, and January 1, 2015 at the LAC + USC (Los Angeles County + University of Southern California) Medical Center., Results: A total of 403 eyes with diabetic tractional retinal detachment in 359 patients were included. Successful reattachment of the retina was achieved in 87.6% of eyes after one surgery and 92.6% of eyes at the final follow-up. Best-corrected visual acuity at the final follow-up improved two or more lines in 56.3% of eyes, was stable in 23.8% of eyes, and decreased two or more lines in 19.9% of eyes. Eyes repaired with 23-gauge and 25-gauge vitrectomy systems had similar success rates as eyes treated with 20-gauge instrumentation (P = 0.73). Eyes receiving silicone oil tamponade had lower single-surgery reattachment rates (77.6% vs. 87.6%; P = 0.013), lower reattachment rates at the final follow-up (85.7% vs. 92.6%; P = 0.048), and higher rates of vision loss (34.7% vs. 19.9%; P < 0.0001) but were more likely to have concurrent rhegmatogenous detachment (47.0% vs. 21.3%; P < 0.0001) and macula involving detachment (74.5% vs. 60.0%; P < 0.0001)., Conclusion: In this large, single-center retrospective study of patients with advanced diabetic tractional retinal detachment, vitrectomy achieved excellent anatomical outcome and improved or stabilized vision in 80.1% of eyes. Smaller gauge vitrectomy systems were found to have similar outcomes to 20-gauge instrumentation.

Purpose: To report the clinical presentation, multimodal imaging, and management of a patient with metastatic melanoma who presented with cystoid macular edema (CME)., Observations: We report a case of a 71-year-old Caucasian male with metastatic melanoma who presented with bilateral cystoid macular edema after being on treatment with a programmed T cell death ligand 1 inhibitor, MPDL3280, for 1 year. Multimodal imaging techniques, including color fundus photographs, autofluorescence, spectral domain optical coherence tomography (OCT), fluorescein angiography (Spectralis, Heidelberg, Germany), and spectral-domain OCT angiography (Zeiss; California, USA) were performed to evaluate the etiology of his CME and to monitor his response to treatment. Clinical examination and multimodal imaging revealed 1 + chronic vitreous cells, an epiretinal membrane, and mild macular edema in both eyes. Fundus autofluorescence showed paravenous hypoautofluorescence in the right eye and scattered hypoautofluorescent spots in the left eye. Optical coherence tomography angiography (OCTA) revealed mild drop out of superficial vessels in the peri-foveal region bilaterally. These findings were concerning for melanoma-associated retinopathy, drug-related uveitis, or activation of a previous chronic autoimmune process. The patient was started on prednisone 30 mg oral daily and ketorolac tromethamine 0.5% 1 drop four times daily. He was then treated with bilateral sustained-release dexamethasone intravitreal implants (Ozurdex). He had complete resolution of CME, and was tapered off of oral steroids within 6 weeks., Conclusions and Importance: Melanoma-associated retinopathy can be accompanied by CME, which presents a diagnostic and therapeutic dilemma in cases where a new drug has been recently initiated. By treating the condition locally, the ophthalmologist may be able to taper systemic immunosuppression more quickly.

Objective: Evaluate individual factors that impact adherence to eye care follow-up in patients with diabetes., Design and Methods: A 4-year retrospective chart review was conducted for 1968 patients with diabetes over age 40 from an urban academic center. Data collected included demographics, insurance, visual acuity, smoking status, medications, dates of dilated fundus examinations (DFE), and reported hemoglobin A1C and blood glucose levels. The primary outcome was timely DFE follow-up adherence following the initial eye exam visit., Results: Overall, 41.6% of patients adhered to initial follow-up eye care recommendations. Multivariable analysis demonstrated that patients with severe diabetic retinopathy (DR) were more adherent than patients with mild DR (OR 1.86). Other variables associated with increased adherence were visual impairment and reported A1C or blood glucose. Smoking was associated with decreased adherence. Ethnicity and insurance were also significantly associated with adherence. Longitudinal follow-up rates were influenced by additional factors, including ethnicity and neighborhood deprivation index., Conclusions: Patients with moderate to severe DR and/or visual impairment were more likely to adhere to timely DFE follow-up. This could relate to the presence of visual symptoms and/or other systemic manifestations of diabetes. Smokers were less likely to adhere to timely DFE follow-up. One hypothesis is patients who smoke have other symptomatic health problems which patients prioritize over asymptomatic ocular disorders. In order to reduce vision loss from DR, practitioners should be aware that patients with mild and moderate DR, patients with normal vision, and smokers are at greater risk for poor follow-up eye care adherence., Competing Interests: Competing interests: None declared.

Purpose: To evaluate the effect of written communication between an ophthalmologist and a primary care physician (PCP) on patient adherence to diabetic eye examination recommendations., Methods: In a retrospective cohort study of a multiethnic population at an urban ophthalmology center, records of all patients with diabetes and clinic visits between 2007 and 2010 were reviewed. Data collected included patient demographics, insurance status, hemoglobin A1C, severity of diabetic retinopathy, follow-up examinations, and written communication between a patient's ophthalmologist and PCP. Statistical analyses were performed to examine the relationship between physician communication and adherence to diabetic eye examination based on the American Academy of Ophthalmology-published recommendations., Results: A total of 1,968 people with diabetes were included. Written communication from an ophthalmologist to a PCP was associated with increased adherence to follow-up eye examination recommendations (Odds Ratio: 1.49; 95% Confidence Interval: 1.16-1.92; P = 0.0018). Communication from a PCP to an ophthalmologist was also associated with increased adherence (Odds Ratio: 1.94; 95% Confidence Interval: 1.37-2.77; P = 0.0002). Multivariable analysis controlling for other factors associated with examination adherence confirmed that communication both to and from an ophthalmologist was independently and significantly associated with increased follow-up adherence., Conclusion: Patients with communication between ophthalmologists and PCPs are more likely to adhere to diabetic eye examinations.

A 25-year-old Hispanic female presented with 5 months of dry eyes and 2 months of bilateral photophobia and decreased vision. On examination, she had bilateral anterior uveitis and mild disc edema of the left eye. A complete infectious and inflammatory work-up was positive for elevated antinuclear antibodies and p-ANCA, leading to a diagnosis of microscopic polyangiitis. One year after initial treatment and steroid taper, an ultra-wide-field fluorescein angiography revealed peripheral vasculitis, outside of the standard traditional field of view, leading to an increase in immunomodulatory therapy and illustrating the utility of wide-field angiography for managing patients with uveitis.

Purpose: To compare the incidence of sustained ocular hypertension (OHT) after intravitreal injections of prepackaged versus freshly prepared bevacizumab monotherapy for the treatment of neovascular age-related macular degeneration., Methods: Charts of 1,216 patients with neovascular age-related macular degeneration receiving intravitreal bevacizumab monotherapy at 2 retina practices using different preparations of bevacizumab between January 1, 2009, and December 31, 2011, were reviewed. Primary outcome was incidence of sustained OHT, defined as intraocular pressure > 25 mmHg with an increase ≥ 6 from baseline on ≥ 2 consecutive visits or requiring treatment., Results: A total of 6,479 injections in 740 eyes of 634 patients were included and 14 eyes (0.81% incidence per eye-year) developed sustained OHT. For eyes receiving prepackaged bevacizumab, 10 of 339 eyes (1.39% incidence per eye-year) developed sustained OHT compared with 4 of 401 eyes (0.39% incidence per eye-year) receiving freshly prepared bevacizumab, giving an incidence rate ratio of 3.55 (95% confidence interval, 0.93-13.49; P = 0.063). All eyes that developed sustained OHT achieved intraocular pressure control with observation or topical therapy alone., Conclusion: Incidence of sustained OHT after intravitreal bevacizumab is low. We found a trend toward higher rates of sustained OHT with prepackaged bevacizumab although this difference was not statistically or clinically significant.

Background and Objective: To investigate outcomes of contemporary surgical techniques for repair of rhegmatogenous retinal detachments (RRD) associated with giant retinal tears (GRT)., Patients and Methods: Retrospective, consecutive case series including 58 eyes of 58 patients. Mean age was 52 years (range: 16 to 83 years). All patients underwent 23-gauge pars plana vitrectomy with use of perfluorocarbon liquid and intravitreal tamponade (28 with silicone oil, 25 with octafluoropropane gas, and five with sulfur hexafluoride gas). Scleral buckle (SB) was placed in 30 eyes (52%)., Results: At a mean follow-up of 17 months, mean visual acuity improved from 20/500 preoperatively to 20/88 at final follow-up. Fifty-one patients (88%) had single-surgery anatomic success, and all patients achieved final retinal reattachment. Use of SB (P = 1.0), silicone oil (P = .1), or 360° endophotocoagulation (P = .7) did not correlate with higher rates of successful repair., Conclusion: Contemporary vitreoretinal surgery techniques achieve high rates of primary anatomic success in GRT-related RRDs., (Copyright 2015, SLACK Incorporated.)

Purpose: To investigate the efficacy of serial anti-vascular endothelial growth factor injections for choroidal neovascularization associated with choroidal osteoma., Methods: In this retrospective interventional case series, eyes with choroidal osteoma and associated choroidal neovascularization were treated with intravitreal ranibizumab or bevacizumab with or without photodynamic therapy consolidation. Resolution of subretinal fluid on optical coherence tomography and best-corrected visual acuity were assessed., Results: Eight eyes in eight patients were treated with monthly intravitreal anti-vascular endothelial growth factor injections with or without photodynamic therapy. Resolution of subretinal fluid on optical coherence tomography was achieved in 7 of 8 eyes (87%) with a mean of 12.3 ± 12.6 injections (range, 1-40). Four eyes (50%) experienced at least 1 recurrence of exudation at a mean interval of 10 months (median, 7.5; range, 5-21 months), necessitating further therapy. The mean Snellen visual acuity improvement was 1 ± 4 lines (range, loss 3 to gain 7 lines) at a mean of 32-months follow-up., Conclusion: Serial anti-vascular endothelial growth factor therapy alone or with photodynamic therapy consolidation for choroidal neovascularization due to choroidal osteoma resulted in anatomical improvement and modest visual gain.
