RESUMO
PURPOSE: In individuals aged >50 years, age-related macular degeneration (AMD) is the leading cause of irreversible blindness. Intravitreal injections of antivascular endothelial growth factor (VEGF) agents (bevacizumab, ranibizumab, and aflibercept) show good efficacy and similar incidences of systemic adverse events (SAEs). However, comparative studies between agents are limited. Our study aimed to compare the real-world SAE risks of bevacizumab, ranibizumab, and aflibercept users. METHODS: This retrospective cohort study identified new bevacizumab, ranibizumab, and aflibercept users in a multi-institutional database in Taiwan between 2014 and 2019. Inverse probability of treatment weights (IPTW) with propensity scores was conducted to achieve homogeneity among groups. The Fine and Gray model was utilized to estimate the subdistribution hazard ratio and 95% confidence interval. RESULTS: This study included 701 bevacizumab, 463 ranibizumab, and 984 aflibercept users. After IPTW, all covariates were well-balanced. All three anti-VEGF agents had a low and comparable number per 100 person-years of major adverse cardiac events, heart failure, thromboembolic events, major bleeding, all-cause admission, and all-cause death (all P > 0.05). No significant differences in long-term change of systolic and diastolic blood pressure, low-density lipoprotein, estimated glomerular filtration rate, and alanine transaminase (all P for interaction > 0.05) were observed among groups. CONCLUSION: Bevacizumab, ranibizumab, and aflibercept had a good systemic safety profile in this study. All groups showed a low and similar SAE risk and no differences in their long-term change of laboratory data. Therefore, these anti-VEGF agents could be prescribed safely to patients with AMD.
RESUMO
Purpose: Commercially available chlorhexidine gluconate (CHG) has a beyond-use date of 24 h. This study evaluated the stability and sterility of 0.05% CHG for 30 days after opening and compared its cost to povidone iodine (PI) for intravitreal injection antisepsis. Methods: 0.05% CHG was aliquoted into 1-mL syringes and stored at room temperature or refrigerated. Turbidity, pH, high-performance liquid chromatography (HPLC), and sterility testing were performed. A cost analysis was conducted. Results: 0.05% CHG remained stable for at least 30 days. All samples had measured turbidity <0.5 nephelometric turbidity units. The pH of all samples remained between 5.0 and 7.0. HPLC demonstrated CHG concentration at day 30 relative to day 0 of 98.52% ± 4.16% at room temperature and 99.99% ± 3.38% at 2°C -6°C. The cost per week to perform 150 injections using 0.05% CHG was $463.25 when opening a new bottle daily compared with $16.73 for 5% PI. This cost decreased to $23.16 when utilizing a bottle of CHG for 30 days. Conclusion: 0.05% CHG remains stable and sterile for at least 30 days after opening. The ability to use CHG for at least 30 days after its opening significantly decreases its utilization expense.
RESUMO
PURPOSE: To investigate outcomes of suprachoroidal triamcinolone acetonide (XIPERE, Bausch + Lomb) for the treatment of refractory postoperative cystoid macular edema. METHODS: Medical records of patients receiving suprachoroidal triamcinolone acetonide for postoperative cystoid macular edema were reviewed. Primary outcomes were visual acuity and central foveal thickness. RESULTS: A total of 32 eyes from 32 patients with a median (interquartile range) follow-up duration of 6 (2-7) months and 1 (1-2) suprachoroidal triamcinolone acetonide injection were included; 19 (59.4%) had a history of vitrectomy. The median (interquartile range) central foveal thickness decreased from 492 (379-629) µm to 267 (187-388) µm at 1 month (P < 0.001), 362 (218-521) µm at 3 months (P = 0.005), and 339 (206-514) µm at the final visit (P < 0.001). The median logarithm of the minimal angle of resolution visual acuity improved from 0.65 (0.48-0.97, 20/89) at baseline to 0.54 (0.35-0.88, 20/69) (P = 0.058) at 1 month, 0.54 (0.33-0.84, 20/69) at 3 months (P = 0.121), and 0.60 (0.33-0.88, 20/80) at the final visit (P = 0.021). Vitrectomized eyes had similar findings. Six eyes (18.8%) developed elevated intraocular pressure (>24 mmHg) (range: 25-49 mmHg) with a median intraocular pressure elevation of 13.5 mmHg compared with baseline, and all had prior glaucoma or ocular hypertension. CONCLUSION: Suprachoroidal triamcinolone acetonide reduced macular edema and improved vision in refractory postoperative cystoid macular edema, including vitrectomized eyes. Intraocular pressure should be monitored, especially in those with a history of glaucoma or ocular hypertension.

PURPOSE: To evaluate outcomes of eyes with post-cataract surgery endophthalmitis that were managed without microbial cultures. DESIGN: This retrospective, single-center comparative cohort study identified all cases of endophthalmitis after cataract surgery presenting between February 1, 2014, and November 1, 2022. SUBJECTS: All eyes presenting with presumed endophthalmitis requiring in-office treatment with intravitreal antibiotics and either a vitreous or aqueous tap were included. METHODS: Endophthalmitis cases were divided into the "culture group" if the vitreous or aqueous specimens were sent for microbiologic sampling or into the "no culture group" if an aqueous or vitreous tap was performed but not sent for microbiologic sampling. MAIN OUTCOME MEASURES: Best corrected visual acuity (VA) 12 months following endophthalmitis presentation, incidence of retinal detachment, and need for subsequent procedures. RESULTS: Of the 232 endophthalmitis cases identified, 196 (85%) were in the "culture group" and 36 (15%) were in the "no culture group". At endophthalmitis presentation, eyes in the "culture group" had a mean (SD) logMAR VA [Snellen Equivalent] of 2.14 (0.8) [20/2760] and mean (SD) logMAR VA in the "no culture group" was 1.93 (0.8) [20/1702] (p=0.185). At 12-month follow up, mean (SD) logMAR VA for the "culture group" was 0.80 (1.0) [20/126] and 0.41 (0.5) [20/50] in the "no culture group" (adjusted difference = 0.41, 95% CI = -0.043 - 0.857, p=0.076). Twenty of 196 (10%) eyes in the "culture group" developed secondary retinal detachments within 12 months of presentation compared to 0 in the "no culture group" (p=0.045). CONCLUSIONS: Eyes with endophthalmitis following cataract surgery managed without microbiologic cultures have similar visual outcomes to eyes managed with microbiologic cultures and may be less likely to develop secondary retinal detachments. This may be an acceptable strategy to manage endophthalmitis after cataract surgery when prompt access to a microbiologic facility is unavailable.
RESUMO
OBJECTIVE: To assess the effect of the COVID-19 pandemic on injection intervals among patients treated for neovascular age-related macular degeneration. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients treated at a single practice using a treat-and-extend regimen with intravitreal aflibercept between December 2018 and April 2021. METHODS: The primary outcome was the change in injection intervals. Secondary outcomes included differences in best-recorded visual acuity (BRVA) and central subfield thickness (CST). Associations were evaluated with linear mixed-effects modelling. RESULTS: This study included 1839 injections from 185 eyes (141 patients). The median (interquartile range) injection intervals in the pre-COVID-19 and COVID-19 periods were 60 (42-70) and 70 (49-90) days, respectively. The pandemic was associated with a mean injection interval lengthening of 7.2 days (P < 0.001), a decrease in BRVA of 3.1 Early Treatment Diabetic Retinopathy Study letters (P < 0.001), and a reduction in CST of 14.7 µm (Pâ¯=â¯0.003). The presence of exudative intraretinal fluid was associated with a reduction in treatment intervals of 11.1 days (P < 0.001), a reduction in BRVA of 1.9 Early Treatment Diabetic Retinopathy Study letters (P < 0.001), and an increase in CST of 52.4 µm (P < 0.001). The presence of subretinal fluid was associated with a reduction in treatment intervals of 8.5 days (P < 0.001) and an increase in CST of 21.6 µm (P < 0.001). CONCLUSIONS: This real-world study estimated that the severe acute respiratory syndrome coronavirus 2 pandemic resulted in an injection extension of 7.2 days with associated decreases in BRVA and CST that are unlikely clinically significant on a population basis. This builds on evidence suggesting that long-term vascular endothelial growth factor suppression can facilitate meaningful interval extensions while maintaining visual acuity.
RESUMO
BACKGROUND AND OBJECTIVE: This study aimed to report retinal displacement incidence following rhegmatogenous retinal detachment (RRD) repair with pars plana vitrectomy (PPV), scleral buckle (SB), or combined SB/PPV. PATIENTS AND METHODS: A single-center, case series using Optos fundus autofluorescence (FAF) images was performed after RRD repair between April 2020 and February 2022. Retinal displacement was identified by imprinted retinal vessels on FAF imaging. RESULTS: One hundred ninety-four eyes were included. Ninety-seven (50.0%) eyes underwent PPV, 46 (23.7%) underwent SB, and 51 (26.3%) underwent SB/PPV. A total of 25/194 eyes (12.9%) had retinal vessel imprinting on FAF imaging consistent with retinal displacement. The SB/PPV group (9/51, 17.6%) and the PPV group (15/97, 15.5%) had significantly higher displacement rates when compared to the SB group (1/46, 2.2%; P = 0.017, P = 0.021, respectively). CONCLUSIONS: Retinal displacement after RRD repair is more prevalent after PPV. There was a low rate of displacement with SB. Retinal displacement was not associated with a visual acuity difference.

RESUMO
Photodynamic therapy (PDT) with verteporfin involves intravenous administration of a photosensitizer followed by its laser light activation at the target site to inhibit aberrant choroidal vascularization. This narrative review provides an overview of the role verteporfin PDT plays in the management of chorioretinal conditions. A PubMed literature review of all English-language articles published through October 19, 2023, was conducted to identify relevant references. Verteporfin PDT has been shown to be safe and effective for the treatment of patients with choroidal neovascularization (CNV) due to neovascular age-related macular degeneration and is often used in combination with a vascular endothelial growth factor (VEGF) inhibitor. Additionally, patients with polypoidal choroidal vasculopathy, a subtype of neovascular age-related macular degeneration, also benefit from verteporfin PDT combined with a VEGF inhibitor for improving visual acuity. Verteporfin PDT has also been effective in treating patients with peripapillary CNV, as well as eyes with CNV due to ocular histoplasmosis and pathologic myopia. Reduced dose and/or fluence PDT protocols have been effective in patients with central serous chorioretinopathy while reducing adverse effects. In eyes with choroidal hemangioma, tumor regression and visual outcomes have been improved with verteporfin PDT treatment. Photodynamic therapy with verteporfin continues to play an important role in the management of chorioretinal conditions.
RESUMO
AIMS: Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are proposed to alleviate the development of inflammatory eye diseases. However, the association between SGLT2i and retinal vascular occlusion remains unclear. Therefore, this study aims to explore the effects of SGLT2i on the incidence of retinal vascular occlusion. MATERIALS AND METHODS: This retrospective cohort study analysed electronic medical records data from the largest multi-institutional database in Taiwan. Individuals who initiated SGLT2is and dipeptidyl peptidase 4 inhibitors (DPP4is) between 2016 and 2019 were included in our analysis. To conduct a homogenous comparison, inverse probability of treatment weighting with propensity scoring was employed. The primary outcome was retinal vascular occlusion, and the secondary outcomes were retinal vascular occlusion-related complications (macular oedema, vitreous haemorrhage, and tractional retinal detachment) and conditions requiring vitreoretinal intervention (intravitreal injection, retinal laser therapy, and vitrectomy). RESULTS: In total, 12,074 SGLT2i users and 39,318 DPP4i users were included. The incidence rate of retinal vascular occlusion in the SGLT2i and DPP4i groups was 1.2 (95% confidence interval [CI], 0.9-1.4) and 1.6 (95% CI, 1.3-1.8) events per 1000 person-years, respectively, which yielded a subdistribution hazard ratio (SHR) of 0.74 (95% CI, 0.55-0.99). Similar risk reductions were observed in the retinal vascular occlusion-related complications (SHR, 0.76; 95% CI, 0.69-0.84) and conditions requiring vitreoretinal intervention (SHR, 0.84; 95% CI, 0.77-0.94). CONCLUSIONS: In this multi-institutional study in Taiwan, SGLT2i use was associated with a reduced risk of retinal vascular occlusion. Further prospective studies are required to ascertain this association.

Purpose: To evaluate the visual, intraocular pressure (IOP), and anatomic outcomes of eyes with loss to follow-up (LTFU) after intravitreal or periocular steroid injections. Methods: Patients receiving intraocular or periocular steroid injections and with LTFU for at least 180 days were included in this retrospective cohort study. Charts were reviewed for the visual acuity (VA), IOP, and central foveal thickness at the visit before LTFU, the first return visit, and 3, 6, and 12 months after return. Results: Fifty-three eyes of 47 patients were identified. The mean (±SD) age was 62.3 ± 14.9 years, the mean LTFU time was 295 ± 181.2 days (range, 182-1101), and the mean follow-up after return was 354 ± 339.3 days (range, 32-1141). The overall mean number of steroid injections was 5.2 ± 3.9 (range, 1-18). Compared with the mean logMAR VA at the visit before LTFU (0.59 [Snellen 20/77]), the mean VA remained stable at all timepoints after return as follows: return visit (0.62 [20/83]; P = .6), month 3 (0.55 [20/70]; P = .6), month 6 (0.55 [20/70]; P = .5), month 12 (0.64 [20/87]; P = .6), and final visit (0.69 [20/97]; P = .2). At the first return visit, 8 (15%) of 53 patients had an IOP of 21 mm Hg or higher (range, 21-31); 2 required treatment with a new antihypertensive medication (latanoprost and timolol, respectively). Conclusions: Patients with LTFU after receiving steroid injections maintained their VA. No patient required incisional glaucoma surgery. Compared with other etiologies, eyes with diabetic macular edema had a greater increase in IOP.
RESUMO
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.

PURPOSE: To determine the risk of endophthalmitis in eyes undergoing intravitreal injections (IVIs) of anti-VEGF based on cumulative number of injections per eye. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients from a single center undergoing IVIs of ranibizumab, aflibercept, or bevacizumab. METHODS: Eyes were divided into quartiles based on injection number causative of endophthalmitis between January 1, 2011, and June 1, 2022. MAIN OUTCOME MEASURES: Interquartile clinical outcomes and cumulative risk of endophthalmitis per injection and per eye. RESULTS: A total of 43 393 eyes received 652 421 anti-VEGF injections resulting in 231 endophthalmitis cases (0.035% per injection, 1 in 2857), of which 215 were included. The cumulative endophthalmitis risk increased from 0.0018% (1 in 55 556) after 1 injection to 0.013% (1 in 7692) after 11 injections (0.0012 percentage point change), versus 0.014% (1 in 7143) after 12 injections to 0.025% (1 in 4000) after 35 injections (0.00049 percentage point change), versus 0.025% (1 in 4000) after 36 injections to 0.031% (1 in 3226) after 66 injections (0.00017 percentage point change), versus 0.031% (1 in 3226) after 63 injections to 0.033% (1 in 3030) after 126 injections (0.000042 percentage point change) (P < 0.001). Likewise, the cumulative endophthalmitis risk per eye increased from 0.028% (1 in 3571) to 0.20% (1 in 500) between injections 1 and 11 (0.018 percentage point change), versus 0.21% (1 in 476) to 0.38% (1 in 263) between injections 12 and 35 (0.0075 percentage point change), versus 0.38% (1 in 263) to 0.46% (1 in 217) between injections 36 and 66 (0.0026 percentage point change), versus 0.46% (1 in 217) to 0.50% (1 in 200) between injections 67 and 126 (0.00063 percentage point change) (P < 0.001). CONCLUSIONS: The cumulative endophthalmitis risk per injection and per eye increased with greater number of injections received but appeared to do so at a higher rate during earlier injections and at a lower rate further into the treatment course.

AIM: To report anatomical and functional outcomes after surgical repair of acute-onset vs delayed-onset rhegmatogenous retinal detachments (RDs) following acute posterior vitreous detachment (PVD). METHODS: A retrospective, comparative interventional cohort study where patients presenting to a single-centre retina practice between October 2015 and March 2020 with delayed RDs (diagnosed ≥42 days after initial presentation of acute PVD) were compared with a 2:1 age-matched and gender-matched acute RD cohort (PVD and RD at initial presentation). The primary outcome was the final attachment rate and single surgery anatomic success (SSAS) at 3 months after RD repair. RESULTS: A total of 210 eyes were analysed-70 in the delayed RD group and 140 in the acute RD group. SSAS was 58/70 (82.9%) for the delayed RD group and 112/140 (80%) for the acute RD group (p=0.71). At the time of RD diagnosis, mean (SD) logarithm of minimum angle of resolution visual acuity (VA) was 0.51 (0.70) (Snellen, 20/65) in the delayed RD group vs 1.04 (0.92) (Snellen, 20/219) in the acute RD group (p<0.001). Mean VA was better at 1 and 3 months post-repair in the delayed RD group (p=0.005 and 0.041, respectively) but similar by 6 months, 12 months and at the final visit post-repair (p=0.48, 0.27, and 0.23, respectively). CONCLUSIONS: Delayed-onset RDs occurring ≥6 weeks after initial presentation to a retina specialist with an acute PVD generally had better VA at the time of RD diagnosis and faster post-surgical visual recovery compared with acute-onset RDs diagnosed at the initial presentation. No significant difference in anatomic outcomes was seen between the two groups.

TOPIC: To compare the efficacy and safety of subthreshold macular laser to conventional focal laser photocoagulation for the treatment of vision loss secondary to diabetic macular edema (DME). CLINICAL RELEVANCE: Macular laser remains an important and cost effective treatment option for vision loss secondary to DME. Although anti-VEGF therapy is often first-line, macular laser is of utility in low-resource or remote settings, for patients at risk of loss to follow-up, and for DME not meeting country-specific reimbursement criteria for anti-VEGF therapy. Subthreshold laser is a modality that does not produce clinical or histologic evidence of thermal damage, thereby potentially limiting the common complications of conventional laser. METHODS: Ovid MEDLINE, EMBASE, and CENTRAL databases were searched for randomized controlled trials (RCTs) from inception to September 28, 2022. Meta-analyses were performed using random-effects modeling. Data were collected at 12 and 24 months for best-corrected visual acuity (BCVA), central retinal thickness, diabetic retinopathy severity scale, rate of adverse events, rate of enrolled patients not completing treatment, rate of patients receiving retreatment, and quality-of-life measures. The risk of bias and certainty of evidence were assessed using Cochrane's Risk-of-Bias version 2 and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) frameworks, respectively. Subgroup analysis was performed between subthreshold laser modalities and evaluated with Instrument to assess the Credibility of Effect Modification Analyses tool. RESULTS: Fourteen RCTs comprising 514 eyes receiving conventional laser and 574 eyes receiving subthreshold laser were included. Subthreshold laser likely results in no difference to BCVA (moderate GRADE certainty) compared with conventional laser. Conventional laser demonstrated a small, statistically significant improvement in central retinal thickness (low GRADE certainty); however, the magnitude of this improvement is unlikely to be clinically important. There may not be a difference in the rate of adverse events (low GRADE certainty) at 12 months when comparing subthreshold laser to conventional laser for DME. CONCLUSION: Randomized controlled trial literature to date suggests subthreshold laser to be as effective as conventional laser in the treatment of DME. Increased follow-up duration is needed to observe any long-term safety benefit from reduced retinal damage.

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.

BACKGROUND: Concerns about the generalizability of pivotal randomized controlled trials (pRCTs) findings have been raised. We aimed to compare intravitreal dexamethasone implants' (IDIs) effectiveness for diabetic macular edema (DME) and central retinal vein occlusion (CRVO), between eyes eligible and ineligible for pRCTs. METHODS: This retrospective cohort study analyzed Taiwan's Chang Gung Research Database, including DME or CRVO eyes initiating IDIs during 2015-2020. We classified all treated eyes as eligible or ineligible for pRCTs following major selection criteria of the MEAD and GENEVA trials, and evaluated three-, six-, and twelve-month changes in central retinal thickness (CRT) and visual acuity (VA) after initiating IDIs. RESULTS: We included 177 IDI-treated eyes (DME: 72.3%; CRVO: 27.7%), of which 39.8% and 55.1% were ineligible for DME and CRVO pRCTs, respectively. LogMAR-VA and CRT changes at different times were comparable in DME eyes eligible (LogMAR-VA difference: 0.11 to 0.16; CRT difference: -32.7 to -96.9 µm) and ineligible (LogMAR-VA difference: -0.01 to 0.15; CRT difference: -54.5 to -109.3 µm) for the MEAD trial. By contrast, CRVO eyes ineligible for the GENEVA trial had greater LogMAR-VA changes (0.37 ~ 0.50) than those eligible (0.05 ~ 0.13), with comparable CRT reductions (eligible eyes: -72.3 to -106.4 µm; ineligible eyes: -61.8 to -110.7 µm) (all p-values <0.05 of the mean differences between eligible and ineligible CRVO eyes for all follow-ups). CONCLUSIONS: IDIs had similar VA and CRT outcomes among DME eyes, regardless of pRCT-eligibility. However, among CRVO eyes, those ineligible for pRCTs showed greater deterioration in VA than those eligible.

With the introduction of therapies to treat geographic atrophy (GA), GA management in clinical practice is now possible. A living systematic review can provide access to timely and robust evidence synthesis. This review found that complement factor 3 and 5 (C3 and C5) inhibition compared to sham likely reduces change in square root GA area at 12 months and untransformed GA area at 24 months. There is likely little to no difference in the rate of systemic treatment-emergent adverse events compared to sham. C3 and C5 inhibition, however, likely does not improve best-corrected visual acuity (BCVA) at 12 months, and the evidence is uncertain regarding change in BCVA at 24 months. Higher rates of ocular treatment emergent adverse effects with complement inhibition occur at 12 months and likely at 24 months. Complement inhibition likely results in new onset neovascular age-related macular degeneration at 12 months. This living meta-analysis will continuously incorporate new evidence.
RESUMO
BACKGROUND: The SARS-CoV-2 pandemic has had a significant impact on healthcare, including eye care, worldwide. Effective and safe vaccines have been developed using both conventional and novel technologies to combat SARS-CoV-2 infection. While vaccination has been shown to be remarkably effective in reducing the spread and associated morbidity and mortality of COVID-19 disease, there have been reports of complications to the posterior segment of the eye. METHODS: We present a case-based analysis of reported complications of COVID-19 vaccination to the posterior segment of the eye. The study aims to highlight the diversity of possible complications and discuss the plausible involved pathophysiologic mechanisms. RESULTS: The most significant complications reported were retinal macro or microvascular occlusions, uveitis, and central serous chorioretinopathy. These complications are rare but require prompt diagnosis and management to prevent serious visual morbidity. CONCLUSIONS: Our study highlights the need for ophthalmologists to be aware of possible complications related to COVID-19 vaccination and the importance of prompt diagnosis and management. The findings of this study may help ophthalmologists to better understand and manage these rare complications.

PURPOSE: To determine the outcomes of intentionally suspending anti-vascular endothelial growth factor (anti-VEGF) injections in eyes with advanced neovascular age-related macular degeneration (nAMD). DESIGN: Retrospective cohort study. METHODS: The study sample comprised 93 patients with nAMD and best available Snellen visual acuity (VA) ≤20/400 in which anti-VEGF treatment was suspended by the treating physician. VA and optical coherence tomography (OCT) characteristics were evaluated to determine visual and anatomical outcomes up to 24 months after treatment suspension. RESULTS: A total of 93 eyes from 93 patients who had received a mean of 16 anti-VEGF injections over a mean of 962 (SD 562) days were included. Comparing the treatment suspension visit to 24 months later, no significant change in mean central foveal thickness (163 [SD 118, range 19-704] µm vs 164 [SD 217, range 19-1468], P = .97), greatest lesion diameter (2547 [SD 1294, range 134-5707] µm vs 2442 [SD 1158, range 421-5305] µm, P = .43), greatest lesion thickness (194 [SD 136, range 0-618] µm vs 205 [SD 131, range 0-573] µm, P = .40), or VA (1.87 [SD 0.37], 20/1482, vs 1.94 [SD 0.28], 20/1741, P = .16) was found. In total, 7 eyes (7.5%) restarted treatment following a mean of 977 (SD 450) days after treatment suspension. CONCLUSIONS: Suspension of anti-VEGF injections in eyes with advanced nAMD and VA ≤20/400 may be reasonable in cases where the treating physician deems additional treatment is unlikely to provide benefit. Although the visual and anatomical findings remained stable after treatment suspension in most, a small number restarted anti-VEGF therapy, suggesting that eyes should still be monitored for disease progression.
