OBJECTIVE: To describe the multimodal imaging features, treatment, and outcomes of patients diagnosed with adult-onset Coats disease.
METHODS: This retrospective study included patients first diagnosed with Coats disease at ≥18 years of age between September 2017 and September 2021. Some patients received anti-vascular endothelial growth factor (VEGF) therapy (conbercept, 0.5 mg) as the initial treatment, which was combined with laser photocoagulation as needed. All the patients underwent best corrected visual acuity (BCVA) and intraocular pressure examinations, fundus color photography, spontaneous fluorescence tests, fundus fluorescein angiography, optical coherence tomography (OCT), OCT angiography, and other examinations. BCVA alterations and multimodal image findings in the affected eyes following treatment were compared and the prognostic factors were analyzed.
RESULTS: The study included 15 patients who were aged 24-72 (57.33±12.61)y at presentation. Systemic hypertension was the most common associated systemic condition, occurring in 13 (86.7%) patients. Baseline BCVA ranged from 2.0 to 5.0 (4.0±1.1), which showed improvement following treatment (4.2±1.0). Multimodal imaging revealed retinal telangiectasis in 13 patients (86.7%), patchy hemorrhage in 5 patients (33.3%), and stage 2B disease (Shield\'s staging criteria) in 11 patients (73.3%). OCT revealed that the baseline central macular thickness (CMT) ranged from 129 to 964 µm (473.0±230.1 µm), with 13 patients (86.7%) exhibiting a baseline CMT exceeding 250 µm. Furthermore, 8 patients (53.3%) presented with an epiretinal membrane at baseline or during follow-up. Hyper-reflective scars were observed on OCT in five patients (33.3%) with poor visual prognosis. Vision deteriorated in one patient who did not receive treatment. Final vision was stable in three patients who received laser treatment, whereas improvement was observed in one of two patients who received anti-VEGF therapy alone. In addition, 8 of 9 patients (88.9%) who received laser treatment and conbercept exhibited stable or improved BCVA.
CONCLUSIONS: Multimodal imaging can help diagnose adult-onset Coats disease. Anti-VEGF treatment combined with laser therapy can be an option for improving or maintaining BCVA and resolving macular edema. The final visual outcome depends on macular involvement and the disease stage.

UNASSIGNED: The intraocular injections of anti-vascular endothelial growth factor (anti-VEGF) demonstrates significant efficacy in inhibiting the formation of ocular neovascularization in neovascular glaucoma (NVG). Ahmed glaucoma valve implantation (AGVI) is extensively employed for the management of diverse glaucoma types.
UNASSIGNED: To further evaluate the efficacy and safety of anti-VEGF combined with AGVI in the treatment of neovascular glaucoma.
UNASSIGNED: A thorough search for randomized controlled trials (RCTs) was conducted across eight databases: PubMed, EMBASE, the Cochrane Library, Web of Science, China National Knowledge Infrastructure, Wanfang, SinoMed, and VIP. The search period was set from the inception of each database until March 2, 2024, to identify RCTs investigating the effectiveness and safety of combining AGVI with anti-VEGF therapy for NVG. We used the Cochrane Risk of Bias Assessment Tool to evaluate the quality of the literature and performed statistical analysis using Stata 15.0 software.
UNASSIGNED: Fourteen RCTs were included in this study. Compared with AGVI alone, the combination of anti-VEGF drugs and AGVI can reduce postoperative intraocular pressure (IOP) at 1 week [WMD = -4.03, 95% CI (-5.73, -2.34), p < 0.001], 1 month [WMD = -5.39, 95% CI (-7.05, -3.74), p < 0.001], 3 months [WMD = -6.59, 95% CI (-7.85, -5.32), p < 0.001], 6 months [WMD = -4.99, 95% CI (-9.56, -0.43), p = 0.032], and more than 12 months [WMD = -3.86, 95% CI (-6.82, -0.90), p = 0.011], with a higher Effective rate [RR = 1.27, 95% CI (1.18, 1.37), p < 0.001], decreased incidence of postoperative hyphema [RR = 0.24, 95% CI (0.15, 0.39), p < 0.001], reduced use of postoperative antiglaucoma medications [WMD = -0.48, 95% CI (-0.61, -0.35), p < 0.001], and decreased aqueous humor VEGF levels [SMD = -2.84, 95% CI (-4.37, -1.31), p < 0.001].
UNASSIGNED: In comparison to AGVI alone, the combination of AGVI with anti-VEGF therapy has better effects in reducing IOP at various time intervals, diminishing postoperative antiglaucoma medication requirements and reducing aqueous humor VEGF levels. Furthermore, it effectively minimizes the incidence of postoperative hyphema. Nevertheless, due to the variability in the quality of the trials included, further high-quality experiments will be required in the future to substantiate this conclusion.

BACKGROUND: Intravitreal injection of anti-vascular endothelial growth factor is considered the first-line treatment for polypoidal choroidal vasculopathy. It has potential risks for circulatory system, which should be particularly carefully evaluated in older patients. In this case study, we aim to discuss the potential impact of this treatment regimen on cardiac health.
METHODS: This case report describes an elderly patient with no prior history of heart disease who exhibited unexpected heart enlargement and dysfunction. Throughout the patient\'s hospital stay, various potential causes were investigated, leading to the hypothesis that a 10-year history of intravitreal injections of anti-vascular endothelial growth factor could be related to the observed clinical manifestations. The patient was advised to discontinue this treatment, and after a 2-month follow-up period, there was a gradual improvement in the patient\'s cardiac structure and function.
CONCLUSIONS: This manuscript highlights the importance of conducting cardiac examinations before and after anti-vascular endothelial growth factor treatment, especially for individuals at risk of heart diseases like the elderly. It emphasizes the need to carefully weigh the benefits and risks of treatment regimens to ensure optimal therapeutic outcomes.

BACKGROUND: To evaluate the impact of reimbursement criteria change on the utilization pattern of anti-vascular endothelial growth factor (anti-VEGF) among patients with wet age-related macular degeneration (wAMD) and diabetic macular edema (DME) separately in Taiwan.
METHODS: An interrupted time series analysis (ITSA) was performed using Taiwan\'s National Health Insurance (NHI) database, and patients with wAMD or DME diagnosis at the first injection of anti-VEGF agents was identified from 2011 to 2019. The outcome of interest was treatment gaps between injections of anti-VEGF. This outcome was retrieved quarterly, and the study period was divided into three phases in wAMD (two criteria changed in August 2014 [intervention] and December 2016 [intervention]) and two phases in DME (three consecutive criteria changed in 2016 [intervention]). Segmented regression models adjusted for autocorrelation were used to estimate the change in level and the change in slope of the treatment gaps between each anti-VEGF injection.
RESULTS: The treatment gaps between each anti-VEGF injection decreased from 2011 to 2019. The cancellation of the annual three needles limitation was associated with significantly shortened treatment gaps between the third and fourth needles (wAMD change in level: -228 days [95% CI -282, -173], DME change in level: -110 days [95% CI -141, -79]). The treatment gap between the fifth and sixth needles revealed a similar pattern but without significant change in DME patients. Other treatment gaps revealed considerable change in slopes in accordance with criteria changes.
CONCLUSIONS: This is the first nationwide study using ITSA to demonstrate the impact of reimbursement policy on treatment gaps between each anti-VEGF injection. After canceling the annual limitation, we found that the treatment gaps significantly decreased among wAMD and DME patients. The shortened treatment gaps might further link to better visual outcomes according to previous studies. The different impacts from criteria changes can assist future policy shaping. Future studies were warranted to explore whether such changes are associated with the benefits of visual effects.

OBJECTIVE: This systematic review and meta-analysis investigates the efficacy and safety of anti-vascular endothelial growth factor (anti-VEGF) injections compared to surgical intervention in improving visual acuity (VA) and reducing complications for patients with submacular hemorrhage (SMH) due to neovascular age-related macular degeneration (AMD).
CONCLUSIONS: Determining the optimal intervention for SMH in AMD is crucial for patient care.
METHODS: We included studies on anti-VEGF injections or surgical interventions for SMH in AMD from 7 databases, searched up to May 2024. Data extraction and quality assessment were done by two independent reviewers. Certainty of evidence was assessed GRADE approach. Meta-analysis employed random-effects models. Primary outcomes were pooled mean logMAR VA difference (initial examination minus last follow-up VA) and adverse events rates.
RESULTS: A total of 43 observational studies were included: 21 (960 eyes) on anti-VEGF and 22 (455 eyes) on surgery. Comparisons were made across separate studies due to lack of head-to-head studies. Meta-analysis included 11 anti-VEGF studies (444 eyes) and 12 surgical studies (195 eyes) for VA outcomes. The mean difference (MD) in VA was -0.16 (95%CI: -0.26,-0.07) for anti-VEGF and -0.36 (95%CI: -0.68,-0.04) for surgery, with no significant difference between groups (X2=1.70, df =1, p=0.19). Heterogeneity was high in surgical studies (I2=96.2%, tau2=0.23, p<0.01) and negligible in anti-VEGF studies (I2=7%, tau2=0.003, p=0.38). GRADE certainty was moderate for anti-VEGF and low for surgery. Anti-VEGF had lower rates of cataract (0% vs 4.6%), proliferative vitreoretinopathy (PVR, 0.1% vs 2.0%), and retinal detachment (RD, 0.1% vs 10.6%), but similar rates of recurrent hemorrhage (5.4% vs 5.3%). Complications were summarized descriptively due to zero cell problem.
CONCLUSIONS: Both anti-VEGF and surgery treat SMH in AMD with similar VA outcomes but different safety profiles. Anti-VEGF is preferred for less severe hemorrhage, while surgery is suited for extensive hemorrhage. Despite uncertain comparative VA outcomes, treatment should be guided by clinical judgment and patient factors.

UNASSIGNED: To explore potential risk factors for the development of neovascular glaucoma (NVG) in central retinal vein occlusion (CRVO) over a two-year intensive follow-up period.
UNASSIGNED: This study reviewed 1545 patients with CRVO between 2005 and 2019 at Taipei Veterans General Hospital. Inclusion was restricted to (1) patients with acute CRVO within 3 months; (2) patients with ocular neovascularization at initial presentation (3) patients had not received any treatment at the time of CRVO; (4) at least bimonthly follow-up schedule over the course of 2 years. The included patients were screened for potential risk factors for developing NVG and assessed with Kaplan-Meier survival analysis and Cox regression model.
UNASSIGNED: Among the included 123 patients, the cumulative probability of developing NVG was 26.8% (33/123 cases) in overall follow-up period. The mean interval between the onset of CRVO and NVG was 507 days. Neither macular edema nor central macular thickness at baseline was correlated with the development of NVG (p =.104 and .25, respectively). Patients with diabetes mellitus (DM), older age, and poor vision independently played significant risk factors for developing NVG after controlling other covariates. (p =.034, .001, and .013, respectively).
UNASSIGNED: Patients presenting with CRVO who have comorbidities such as DM, older age, and worse VA warrant closer attention and intensive follow-up for the development of NVG. Additionally, the statistical analysis indicated that the presence of macular edema, increased central macular thickness, CV events, history of glaucoma, and early PRP within 3 months had no significant impact on the likelihood of developing NVG.

UNASSIGNED: We report on one case of age-related macular degeneration and one case of diabetic macular edema with concomitant retinal arterial macroaneurysm (RAM) that were treated with anti-vascular endothelial growth factor (VEGF) intravitreal injections.
UNASSIGNED: Case 1 involved a 71-year-old woman with a 30-year history of diabetes who was undergoing dialysis. Pretreatment visual acuity in the right eye was 0.4. Fundus fluorescein angiography (FA) showed that numerous microaneurysms and RAM were located at a distance of two papillary diameters from the macular area. Diabetic macular edema was diagnosed. After 12 anti-VEGF injections, the macular edema resolved, microaneurysms decreased, and the RAM also disappeared. Visual acuity in the right eye improved to 0.7. Case 2 involved an 81-year-old woman receiving treatment for disorders including hypertension and dyslipidemia. Pretreatment visual acuity in the right eye was 0.03. And vitreous hemorrhage was present. After one ranibizumab intravitreal injection, the fundus became clearly visible. Macular subretinal hemorrhage and an RAM in the upper macula area were evident on FA and optical coherence tomography. After four intravitreal injections of ranibizumab, macular hemorrhage resolved, RAM disappeared, and visual acuity improved to 0.2. All cases were treated by intravitreal injection of anti-VEGF. After several injections, the macular hemorrhage or macular edema was resolved. RAM disappeared, and visual acuity improved.
UNASSIGNED: Intravitreal injection of anti-VEGF appears effective for age-related macular degeneration or diabetic macular edema with concomitant RAM. Although anti-VEGF intravitreal injections are not covered by health insurance for the treatment of RAM, their effectiveness means that the expansion of indications is desirable.

This study aims to determine the impact of adjunct nondamaging focal laser therapy on the number of anti-vascular endothelial growth factor (anti-VEGF) injections and visual acuity (VA) and imaging in patients with diabetic macular edema (DME). A retrospective analysis of 18 eyes of 14 patients with DME treated with a single session of the PASCAL 532 nm Synthesis Photocoagulator with Endpoint Management was conducted. Demographic data, VA, imaging, laser parameters, and anti-VEGF injection burden six months before and after treatment were collected. Wilcoxon Signed-rank tests were used to assess changes in VA and injection burden before and after treatment. The mean number of intravitreal injections in the six-month period prior to laser treatment was 3.39 ± 2.57 injections compared to 2.33 ± 2.40 injections following laser treatment (p = 0.02). There was no significant difference between the mean VA on the day of treatment logMAR VA of 0.38 ± 0.27 (approx. Snellen equivalent 20/50) and the visual acuity on the most recent follow-up 6 months after laser logMAR VA of 0.35 ± 0.32 (approx. Snellen equivalent 20/40) (p = 0.34). There was also no significant difference in OCT central macular thickness before (311 μm) compared to 6 months after (301 μm, p = 0.64). Adjunct focal macular laser therapy is associated with a statistically and clinically significant decrease in the number of intravitreal injections required in the six-month period immediately following treatment, without compromising visual acuity or macular thickness. Nondamaging focal laser has the potential to alleviate the burden of injections for both patients and clinics.

Diabetic papillopathy (DP), a form of optic disc edema, is characterized by decreased visual acuity and mild to severe visual field defects. While there is no consensus about treatment, some publications report that intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection may be beneficial. To our knowledge, however, no research reports on the effects of combining anti-VEGF injection and oral steroids in DP treatment. In this case report we present three DP cases that showed rapid improvement following therapy with intravitreal bevacizumab and oral steroids. Optic disc edemas were significantly decreased, and visual acuities were markedly increased in the first week of treatment. This report suggests that combined use of these therapies may be safely used in patients diagnosed with DP.

OBJECTIVE: To determine the proportion and characteristics of eyes with neovascular age-related macular degeneration (nAMD) treated with the Port Delivery System (PDS) with ranibizumab that receive supplemental intravitreal ranibizumab injections because of changes in best-corrected visual acuity (BCVA) or central subfield thickness (CST), or both, and to investigate the safety and efficacy of supplemental injections in eyes with the PDS.
METHODS: Post hoc analyses of data from the phase III, randomized, multicenter, open-label, active-comparator Archway trial (NCT03677934).
METHODS: Adults with nAMD diagnosed within 9 months of screening previously responsive to anti-VEGF therapy.
METHODS: Four hundred eighteen patients were randomized to the PDS with ranibizumab 100 mg/ml with fixed refill-exchanges every 24 weeks (Q24W) or monthly intravitreal ranibizumab 0.5 mg for 96 weeks.
RESULTS: Of the 246 eyes treated with the PDS Q24W and assessed for supplemental treatment criteria, the vast majority (94.6%-98.4%) did not receive supplemental treatment during each retreatment interval, with 87.4% not receiving supplemental treatment at any point during the trial. Of the 31 eyes receiving supplemental treatment, 58.1% received 1 injection and 32.3% received 2. At baseline, eyes receiving supplemental treatment were significantly more likely to have thicker retinas (mean CST, 370.5μm vs. 304.4μm; P = 0.0001), subretinal fluid (54.8% vs. 21.2%; P < 0.0001), and larger pigment epithelial detachment height (215.7 μm vs. 175.9 μm; P = 0.003). These features have previously been associated with difficult-to-treat nAMD. Although BCVA and CST generally remained constant throughout the trial in eyes without supplemental treatment, the small number of eyes receiving supplemental treatment on average lost 1 line of vision from baseline to week 96 (mean, -5.7 ETDRS score letters) and CST continued to increase over time. Absolute BCVA at week 96 was similar irrespective of supplemental treatment status (71.1 and 73.7 letters). Best-corrected visual acuity and CST generally improved within 28 days of supplemental treatment.
CONCLUSIONS: Although the PDS Q24W effectively maintains vision and retinal stability in most eyes with nAMD, a small proportion of patients with features of difficult-to-treat nAMD may benefit from supplemental intravitreal anti-VEGF injections and initial close monitoring is recommended.
