Forty-three patients with glaucoma and 24 patients with ocular hypertension presenting with a retinal vein occlusion were medically assessed. The prevalence of systemic hypertension was 60.5% in those with glaucoma and 66.6% with ocular hypertension. The prevalence of hyperlipidaemia was 38.1% in those with glaucoma and 37.5% in those with ocular hypertension. These findings were compared with ...

PURPOSE To evaluate the effect of intravitreal bevacizumab on the visual and anatomical outcome in eyes with macular edema secondary to branch retinal vein occlusion. METHODS A retrospective, consecutive case series identified 53 consecutive patients with a branch retinal vein occlusion treated with intravitreal bevacizumab. Clinical variables were analyzed, including best-corrected visual ac...

BACKGROUND Retinal vein occlusion is the second most common vascular disease of retina after diabetic retinopathy, affecting 1.6% of the population above the age of 40. The aim of this study was to compare the effect of dalteparin and aspirin in patients with recent-onset branch retinal vein occlusion. METHODS A randomized clinical trial was conducted on patients with branch retinal vein occl...

Retinal vein occlusion is a leading cause of visual impairment. Experimental models of this condition based on laser photocoagulation of retinal veins have been described and extensively exploited in mammals and larger rodents such as the rat. However, few reports exist on the use of this paradigm in the mouse. The objective of this study was to investigate a model of branch and central retinal...

The objective of this study was to evaluate the relations among electroretinogram (ERG) parameters (cone a-wave, cone b-wave, and 30 Hz flicker), retinal thickness, and retinal volume in 16 patients with central retinal vein occlusion and macular edema. The amplitude and implicit time of the ERG parameters were extracted from the ERG traces. Retinal thickness and volume were measured by optical...

Macular edema is a common cause of visual loss in patients with retinal vein occlusions. Ozurdex(®), a dexamethasone intravitreal implant, has been shown in randomized controlled trials to reduce macular edema and improve visual acuity in patients with either branch retinal vein occlusions or central retinal vein occlusions. It was approved in the United States in 2009. Since then, new therapeu...

purpose : churg-strauss syndrome (css) is a rare form of small vessel necrotizing vasculitis. retinal artery and vein occlusion are very rare findings in these patients and they are treated by high-dose corticosteroids and cytotoxics. we describe a rare case of css under high-dose corticosteroids and cytotoxic treatment, presenting central retinal artery occlusion (crao). case report : a 45-yea...

Simultaneous branch retinal artery and vein occlusion is a rare condition that may cause severe visual loss, and its treatment is often unrewarding. Herein, we report a case with simultaneous central retinal vein and branch retinal artery occlusion; it was successfully treated with a single dexamethasone intravitreal implant. The affected eye attained a visual acuity level of 20/25 from the vis...

purpose : to evaluate the intraocular pressure (iop) rising effect of anterior versus posterior subtenon injection of triamcinolone in eyes with retinal vein occlusion methods : this prospective nonrandomized study was performed on 57 eyes of 57 patients with macular edema due to retinal vein occlusion. 26 eyes received posterior subtenon injection of 40 mg triamcinolone acetonide [pstt] and 31...
