Geographic Atrophy and micronutritional supplements: A complex relationship.

Geographic Atrophy and micronutritional supplements: A complex relationship. J Fr Ophtalmol. 2019 Nov 10;: Authors: Desmettre T Abstract In 2019, the Age-Related Eye Disease Study (AREDS) remains the basis for micronutritional supplement guidelines aiming to slow the progression of Age-Related Macular Degeneration (AMD) and reduce the risk of neovascularization. However, for Geographic Atrophy (GA) patients specifically, there seem to be more arguments for prescribing micronutritional supplements for the prevention of neovascular complications than to slow the progression of the atrophy. The AREDS report 8 showed a significant decrease in AMD progression over a five-year follow-up associated with a formulation containing antioxidants and zinc. It is noteworthy that the protective effect that was demonstrated was mainly related to the risk of a neovascularization and that the AREDS did not really demonstrate a protective effect that would slow the progression of GA. The 2013 AREDS II results have led to a change in the AREDS formulation. Nevertheless, the replacement of beta-carotene by lutein and zeaxanthine and the addition of Omega-3 did not add any further evidence for a protective effect on GA. Furthermore, the AREDS study used color photographs rather than fundus autofluorescence or OCT to assess the presence or the evolution of patches of atrophy. Over the last 10 years, it has been shown that OCT is far more accurate than color photographs to measu...

CONCLUSION: In this post hoc analysis, fixed dosing with an anti-VEGF agent over 52 weeks eliminated disease activity (absence of both leakage and fluid) in most eyes. The effect of anti-VEGF treatment on leakage/fluid status favoured PC versus occult lesions. PMID: 31826853 [PubMed - as supplied by publisher]

Abstract PURPOSE: To evaluate visual and anatomic outcomes following pars plana vitrectomy and intravitreal or subretinal tissue plasminogen activator for submacular hemorrhage in patients with age-related macular degeneration. METHODS: This was a retrospective study on patients with a minimum follow-up of 12 months undertaken at a tertiary referral center. Data collected include demographic details, visual and optical coherence tomography changes, surgical details, and complications. Surgical results were compared with patients who were age and lesion size matched and treated with anti-vascular endoth...

This study aimed to identify and describe anatomical and functional changes on short (1-3 months) and medium (6-12 months) term after intravitreal injections of bevacizumab (Avastin, Genentech) in patients with choroidal neovascularization (CNV) in the context of exudative form of age-related macular degeneration (AMD). We performed a retrospective, analytical, interventional study, based on a series of cases with exudative form of AMD, which also comprised a prospective component related to the inclusion and treatment of the patients with a very new interventional method for that time (2006) and the follow-up of the effec...
