OBJECTIVE To confirm the relationship between resistance to activated protein C (APC), factor V Leiden, and central retinal vein occlusion in young adults as reported in a recent study of patients younger than 50 years. PATIENTS AND METHODS Patients younger than 50 years with central retinal vein occlusion were identified from the medical records of the Wills Eye Hospital Retina and Retina Va...

Retinal vein occlusion (RVO) is a prevalent retinal vascular disease, second only to diabetic retinopathy. Previously there was no treatment for central retinal vein occlusion (CRVO) and patients were simply observed for the development of severe complications, generally resulting in poor visual outcomes. The only treatment for branch vein occlusion (BRVO) was grid laser photocoagulation, which...

PURPOSE To evaluate plasma pentraxin 3 (PTX3) in patients with retinal vein occlusion (RVO), and investigate the possibility of its role as a predictive biomarker. METHODS Nested case-control study. The study included 57 patients with RVO and 45 age- and gender-matched subjects without RVO as controls. Plasma PTX3 and C-reactive protein concentration were measured in both groups a posteriori ...

Optical coherence tomography angiography (OCTA) is a new, noninvasive technology that enables detailed evaluation of flow in the retinal and choroidal vasculature. The authors believe this to be the first report to describe the optical coherence tomography angiography findings associated with combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO).

BACKGROUND Ocular vascular occlusions following intraocular procedures are a rare complication. We report a case series of patients with retinal vascular occlusions or anterior ischemic optic neuropathy (AION) after anterior and posterior segment surgery and demonstrate possible risk factors. METHODS Observational case series. RESULTS In ten patients, vascular occlusions were observed withi...

BACKGROUND This study aims to explore the prevalence, pattern and risk factors of retinal vein occlusion (RVO) in an elderly population of Nepal. METHOD One thousand eight hundred sixty subjects of age 60 years and above were enrolled in a population-based, cross-sectional study. Detailed history, visual acuity, anterior segment and posterior segment examinations were done. Blood pressure, no...

INTRODUCTION Can vitamin B12 and folate deficiency cause central retinal vein occlusion? We conducted a literature search to find out whether nutritional deficiency of vitamin B12 and folate can lead to impaired vision. CASE PRESENTATION The patient in the article presented in an eye-casualty department in the North East of England with gradual painless visual loss over six weeks. She was fou...

The intraocular pressure of 59 patients with retinal vein occlusion was studied. Central retinal vein occlusion (CVO) was diagnosed in 24 patients and branch retinal vein occlusion (BVO) was diagnosed in the rest. The intraocular pressure of a sex and age matched group of controls was also studied for comparison. The intraocular pressure in the CVO group were significantly different from those ...

A 60-year-old woman with a past medical history of branch retinal vein occlusion presented with decreased vision and metamorphopsia in her left eye. A fundus examination revealed a tortuous retinal vein with a few retinal hemorrhages in the inferotemporal quadrant. Optical coherence tomography revealed a partially separated posterior vitreous membrane pulling up the fovea. The patient refused s...

years; range 41-77 years. There were 16 (35.6%) male patients and 29(64.4%) female patients. Thirty-eight (84.4%) patients (40 eyes) had central retinal vein occlusion (CRVO), 7 (15.6%) patients (8 eyes) had branch vein occlusion (BRVO), and 29 (60.4%) eyes (all CRVO) had ischaemic vein occlusion. Twenty-eight (58.3%) eyes were blind, while 18 (37.5%) had visual impairment. Twenty-five (55.6%) ...
