A 77-year-old man presented with an inferior hemivisual field defect in the left eye. Funduscopy revealed well demarcated retinal edema of the superior quadrant resembling hemicentral retinal artery occlusion. Further, the upper and inferior retinal arteries emerged separately from the optic disc. Fluorescein angiography demonstrated a marked filling delay of the upper retinal artery. We repeat...

A 59-year-old woman with history of noninsulin dependent diabetes mellitus and systemic hypertension presented with decreased vision in her left eye since 2 months ago. Bestcorrected visual acuity (BCVA) was 20/20 and 20/400 in the right and left eyes respectively. Relative afferent pupillary defect was negative. Anterior segment examination was unremarkable except for mild posterior subcapsula...

PURPOSE To investigate the effect of intravitreal bevacizumab (IVB) injections for macular edema secondary to acute branch retinal vein occlusion on the retinal microcirculation. METHODS The study was a prospective, interventional case series. Central macular thickness using spectral-domain optical coherence tomography and retinal blood flow (RBF) in untreated eyes with macular edema secondar...

BACKGROUND We report a case of bilateral central retinal artery occlusion and the evaluation of retinal vasculature and capillaries by using optical coherence tomography angiography. CASE PRESENTATION A 75-year-old white man presented with central retinal artery occlusion in one eye and underwent a carotid angioplasty. Upon discontinuing anticoagulant, he had a subsequent central retinal arte...

PURPOSE To evaluate the co-occurrence of acute ischemic stroke and acute retinal artery occlusion (RAO). DESIGN Retrospective observational case series. METHODS We included 33 consecutive patients with acute RAO who underwent diffusion-weighted magnetic resonance imaging within 7 days of the onset of visual symptoms. The causes of RAO were classified according to the Trial of Org 10172 in A...

A 61-year-old man presented with acute, painful loss of vision in the left eye due to a central retinal artery occlusion. Fluorescein angiography confirmed the central retinal artery occlusion and also identified a nasal posterior ciliary artery occlusion. CT scanning revealed a left medial orbital mass with adjacent ethmoid sinusitis. Transnasal ethmoid biopsy disclosed mucormycosis. A left ex...

OBJECTIVE To investigate the response of retinal vessel diameters to photocoagulation treatment and their role for the success of laser treatment in patients with retinal vein occlusion. METHODS The study included 14 patients with branch vein occlusion or macular vein occlusion. The ophthalmologic examination included best-corrected visual acuity, biomicroscopy, fundus photography, and fluore...
