Real-world treatment outcomes of neovascular Age-related Macular Degeneration in the Netherlands

Purpose: To compare treatment outcomes of treatment-naïve eyes with neovascular age-related macular degeneration (nAMD) with bevacizumab as the first-line treatment, according to the guidelines of the Dutch Ophthalmological Society, with those treated first with either ranibizumab or aflibercept, as used in many other countries, all treated using a treat-and-extend strategy. Methods: Data were obtained from the prospectively designed Fight Re

Treatment of Branch Retinal Vein Occlusion induced Macular Edema with Bevacizumab

BACKGROUND: Branch retinal vein occlusion is a frequent cause of visual loss with currently insufficient treatment options. We evaluate the effect of Bevacizumab (Avastin) treatment in patients with macular edema induced by branch retinal vein occlusion. METHODS: Retrospective analysis of 32 eyes in 32 patients with fluorescein angiography proven branch retinal vein occlusion, macular edema and Bevacizumab treatment. Outcome measures were best corrected visual acuity in logMAR and central retinal thickness in OCT. RESULTS: Visual acuity was significantly better 4 to 6 weeks after Bevacizumab treatment compared to visual acuity prior to treatment (before 0.7 +/- 0.3 and after 0.5 +/- 0.3; mean +/- standard deviation; p < 0.01, paired t-test). Gain in visual acuity was accompanied by a significant decrease in retinal thickness (454 +/- 117 to 305 +/- 129 microm, p < 0.01, paired t-test). Follow up (170, 27 - 418 days; median, range) shows that improvement for both visual acuity and retinal thickness last for several months after Bevacizumab use. CONCLUSION: We present evidence that intravitreal Bevacizumab is an effective and lasting treatment for macular edema after branch retinal vein occlusion

Defining a Minimum Set of Standardized Patient-centered Outcome Measures for Macular Degeneration

Purpose To define a minimum set of outcome measures for tracking, comparing, and improving macular degeneration care. Design Recommendations from a working group of international experts in macular degeneration outcomes registry development and patient advocates, facilitated by the International Consortium for Health Outcomes Measurement (ICHOM). Methods Modified Delphi technique, supported by structured teleconferences, followed by online surveys to drive consensus decisions. Potential outcomes were identified through literature review of outcomes collected in existing registries and reported in major clinical trials. Outcomes were refined by the working group and selected based on impact on patients, relationship to good clinical care, and feasibility of measurement in routine clinical practice. Results Standardized measurement of the following outcomes is recommended: visual functioning and quality of life (distance visual acuity, mobility and independence, emotional well-being, reading and accessing information); number of treatments; complications of treatment; and disease control. Proposed data collection sources include administrative data, clinical data during routine clinical visits, and patient-reported sources annually. Recording the following clinical characteristics is recommended to enable risk adjustment: age; sex; ethnicity; smoking status; baseline visual acuity in both eyes; type of macular degeneration; presence of geographic atrophy, subretinal fibrosis, or pigment epithelial detachment; previous macular degeneration treatment; ocular comorbidities. Conclusions The recommended minimum outcomes and pragmatic reporting standards should enable standardized, meaningful assessments and comparisons of macular degeneration treatment outcomes. Adoption could accelerate global improvements in standardized data gathering and reporting of patient-centered outcomes. This can facilitate informed decisions by patients and health care providers, plus allow long-term monitoring of aggregate data, ultimately improving understanding of disease progression and treatment responses

Delayed Appearance of High Altitude Retinal Hemorrhages

When closely examined, a very large amount of climbers exhibit retinal hemorrhages during exposure to high altitudes. The incidence of retinal hemorrhages may be greater than previously appreciated as a definite time lag was observed between highest altitude reached and development of retinal bleeding. Retinal hemorrhages should not be considered warning signs of impending severe altitude illness due to their delayed appearance

A pharmacoepidemiologic study of ranibizumab and aflibercept use 2013–2016. The Fight Retinal Blindness! Project

International audienceINTRODUCTION:To report 12-month pharmacoepidemiologic data on aflibercept and ranibizumab use in treatment-naïve eyes with neovascular age-related macular degeneration (nAMD).METHODS:Participants were treatment-naïve eyes with nAMD tracked by the Fight Retinal Blindness! registry starting therapy with aflibercept or ranibizumab treatment between January 1st, 2013 and 31st December, 2016. Demographic and clinical characteristics were compared between treatment groups.RESULTS:During the study period, 689 eyes initiated treatment with ranibizumab compared to 568 with aflibercept. We found a similar rate of use of both drugs. Ranibizumab-treated patients were older than aflibercept-treated patients (overall mean [SD] 82.0 [8.4] vs. 78.6 [8.1], P < 0.001). Median (Q1, Q3) lesion size was significantly larger in aflibercept-treated patients (2450 μm [1242, 3000]) compared with ranibizumab patients (2000 μm [1148, 2890], P = 0.008). Eyes treated with ranibizumab and aflibercept received a similar mean number of injections in the first 3 months (3.1 [0.7] vs. 3.0 [0.6]; P = 0.233) and at 12 months (7.3 [2.4] vs. 7.2 [2.2]; P = 0.139). The 12-month switching rates from 2013 onwards for eyes completing 12 months of follow-up were much higher for switching from ranibizumab to aflibercept (19.2%) compared with switching from aflibercept to ranibizumab (5.4%). The proportion of eyes that did not complete 12 months of treatment was 23.2% for ranibizumab and 22.2% for aflibercept-treated groups.CONCLUSION:A similar rate of use for ranibizumab and aflibercept among Australian practitioners was observed between 2013 and 2016. Ranibizumab was used more often in older patients while aflibercept tended to be used more often in eyes with larger lesions

Real-world treatment outcomes of neovascular Age-related Macular Degeneration in the Netherlands

PURPOSE To compare treatment outcomes of treatment-naïve eyes with neovascular age-related macular degeneration (nAMD) with bevacizumab as the first-line treatment, according to the guidelines of the Dutch Ophthalmological Society, with those treated first with either ranibizumab or aflibercept, as used in many other countries, all treated using a treat-and-extend strategy. METHODS Data were obtained from the prospectively designed Fight Retinal Blindness! outcomes registry. The primary outcome was the mean change from baseline in visual acuity of all treated eyes, after 12, 24 and 36 months of treatment. Secondary outcomes were the number of injections, the number of visits and the rate of switching to a second anti-VEGF drug. RESULTS The study included 703 treatment-naïve eyes with nAMD with 12 months follow-up, 373 eyes with 24 months follow-up, and 171 eyes with 36 months follow-up in the Netherlands, and 1131, 652, and 303 treatment-naïve eyes with respectively 12, 24, and 36 months of follow-up in all other countries. The change in visual acuity from baseline did not differ between the Netherlands and the other countries at any follow-up time. The median number of injections, visits and the proportion of eyes switching treatment was significantly higher in the Netherlands than in the other countries. CONCLUSION Starting anti-VEGF treatment for nAMD with bevacizumab, as is mandatory in the Netherlands, delivers outcomes similar to those starting treatment with either ranibizumab or aflibercept, but at a cost of more frequent injections, and visits, and more frequent switching treatment to a second drug

Neovascular age-related macular degeneration: A review of findings from the real-world Fight Retinal Blindness! registry

The use of vascular endothelial growth factor (VEGF) inhibitors has revolutionised the treatment of neovascular age-related macular degeneration (nAMD) since the pivotal Phase III studies demonstrated their efficacy more than 10 years ago. The Fight Retinal Blindness! project was developed to track the treatment outcomes of patients with nAMD in real-world practice. Data from this registry have been used to answer several clinically relevant questions related to the treatment of nAMD including the effect of under-treatment, the comparative effectiveness of different anti-vascular endothelial growth factor agents, long-term treatment outcomes, identifying optimal treatment regimens and the rate and outcomes of rare adverse events. Observational studies are a valuable complement to the shortcomings of clinical trials and a combination of data from real-world settings and clinical trials are necessary to provide evidence on how to achieve the best outcomes for individual patients with nAMD
