To evaluate the long-term outcome of an OCT-guided reinjection scheme for bevacizumab treatment of macular edema (ME) due to retinal vein occlusion. Patients with persistent ME (>250 μm) due to central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO) received intravitreal bevacizumab 2.5 mg/0.1 ml. Visual acuity (ETDRS), ophthalmic(More)
To evaluate prognostic factors of response to intravitreal bevacizumab therapy of macular edema (ME) due to central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO). Patients with ME due to CRVO (32 patients) or BRVO (38 patients) received intravitreal bevacizumab (2.5 mg/0.1 ml) at baseline, and every 6 to 8 weeks if OCT showed(More)
Baseline OCT morphology of macular edema (ME) due to branch (BRVO) or central retinal vein occlusion (CRVO) was evaluated with respect to response to bevacizumab treatment. Sixty-five patients (33 CRVO, 32 BRVO) were treated with intravitreal injections of 2.5 mg bevacizumab. Reinjections were only performed if ME persisted or recurred. Follow-up ranged(More)
PURPOSE Lipofuscin (LF) accumulation within RPE cells is considered pathogenic in AMD. To test whether LF contributes to RPE cell loss in aging and to provide a cellular basis for fundus autofluorescence (AF) we created maps of human RPE cell number and histologic AF. METHODS Retinal pigment epithelium-Bruch's membrane flat mounts were prepared from 20(More)
PURPOSE Lipofuscin (LF) and melanolipofuscin (MLF) of the retinal pigment epithelium (RPE) are the principal sources of autofluorescence (AF) signals in clinical fundus-AF imaging. Few details about the subcellular distribution of AF organelles in AMD are available. We describe the impact of aging and AMD on RPE morphology revealed by the distribution of AF(More)
Age-related macular degeneration (AMD) is a chronic degenerative disease of the central retina and a major cause of vision impairment and blindness with millions of people affected in the elderly population. In recent years, considerable efforts have been made to understand disease pathology with the long-term goal of designing novel and effective treatment(More)
PURPOSE To seek pathways of retinal pigment epithelium (RPE) fate in age-related macular degeneration via a morphology grading system; provide nomenclature, visualization targets, and metrics for clinical imaging and model systems. METHODS Donor eyes with geographic atrophy (GA) or choroidal neovascularization (CNV) and one GA eye with previous clinical(More)
Antibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have been reported in patients with aquaporin-4 antibody (AQP4-IgG)-negative neuromyelitis optica spectrum disorders (NMOSD). The objective of this study was to describe optic neuritis (ON)-induced neuro-axonal damage in the retina of MOG-IgG-positive patients in comparison with(More)
PURPOSE To describe, illustrate, and account for two cell types plausibly derived from RPE in geographic atrophy (GA) and choroidal neovascularization (CNV) of AMD, using melanosomes, lipofuscin, and basal laminar deposit (BLamD) as anatomical markers. METHODS Human donor eyes with GA (n = 13) or CNV (n = 39) were histologically processed,(More)
