In this large series of patients with choroidal neovascularization associated with angioid streaks followed for 4 years, ranibizumab injections allowed stabilization of best-corrected visual acuity in most eyes. Ranibizumab appear as an effective therapeutic option in CNV associated with angioid streaks over long time.
Intravitreal dexamethasone implant provides anatomic and functional improvements and may represent a valuable treatment option for patients with ME secondary to RP.
Age-related macular degeneration (AMD) is a complex, multifactorial disease associated with environmental and genetic factors. This review emphasizes the clinical impact of the major genetic factors mainly located in the complement factor H gene and on the 10q26 locus, and their current and future implications for the management of AMD.
Purpose:
To compare widefield optical coherence tomography angiography (OCTA) to ultra-widefield fluorescein angiography (UWFA) in the assessment of nonperfusion in retinal vein occlusion (RVO).
Methods:
A cross-sectional study of 43 eyes of 43 patients with RVO examined using both widefield OCTA (PLEX Elite, Carl Zeiss Meditec, Dublin, CA) with a panoramic montage of five 12 × 12-mm images and UWFA (Optos, 200°). Qualitative analysis was performed according to nonperfusion areas (cutoff: three disk areas) on widefield OCTA. The quantitative analysis assessed the vascular density on the widefield OCTA and ischemic index on UWFA.
Results:
The ischemic index on UWFA and vascular density in the superficial and deep plexus correlated significantly (P = 0.019, r = 0.357 and P < 0.013, r = 0.375, respectively). The qualitative classification on widefield OCTA and ischemic index on UWFA correlated significantly (P < 0.001, r = 0.618). For the detection of marked nonperfusion (ischemic index ≥ 25%), widefield OCTA had a sensitivity of 100% and a specificity of 64.9%.
Conclusion:
The presence of nonperfusion on UWFA correlated with widefield OCTA. Optical coherence tomography angiography could help to identify high-risk RVO patients who might benefit from a further evaluation using fluorescein angiography.
Macular edema may rarely lead to MHs, by inducing mechanical changes and probable inflammatory mechanisms as well as a thinning of the fovea. We report a case of spontaneous closure of MH complicating a PCME, with medical treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
