Retinal artery occlusions (RAO) are characterized by the sudden obstruction of the arterial blood flow in the retinal circulation with consequent ischemic damage to the retina. RAO can be subdivided into several forms, including central retinal artery occlusion (CRAO) and Branch retinal artery occlusion (BRAO). Patients affected by CRAO experience a sudden, monocular loss of vision. On fundus b...

We retrospectively studied 46 patients with symptomatic retinal artery occlusion and assessed the pattern and extent of carotid artery disease ipsilateral to the retinal artery occlusion. Ipsilateral internal carotid artery atherosclerotic lesions were virtually limited to the cervical arterial segment; 50% of such lesions were plaques or stenoses of less than or equal to 60%, whereas 15% of th...

  Background :In addition to diagnosing the acute myocardial infarction (MI), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting MI. Many studies have been conducted to predict the occlusion site by interpreting the ST segment deviations in Electrocardiogram (ECG).Additional posterior and right precor...

Doppler ultrasound was used to detect possible flow changes in the carotid arteries of patients with central retinal artery and vein occlusion. Twenty-three patients with central retinal artery occlusion (mean age 56, SD 11, years) were examined 4 to 48 months after the development of the occlusion and compared with age and sex matched control subjects with no history of any disease known to be...

Branch retinal vein occlusion induces complex biological processes in the retina that are generated by a multitude of interacting proteins. These proteins and their posttranslational modifications can effectively be studied using modern proteomic techniques. However, no method for studying large-scale protein changes following branch retinal vein occlusion has been available until now. Obtainme...

BACKGROUND Cilioretinal artery occlusion rarely results in neovascular glaucoma, especially in cases of extensive cilioretinal infarction and combined retinal vascular occlusion. CASE A 62-year-old man with diabetes mellitus and essential hypertension showed a visual acuity of counting fingers, retinal whitening temporal to the optic disc with mild dilation and tortuosity of the retinal veins...

AIMS AND OBJECTIVES To determine the association of Primary glaucoma with retinal vein occlusion. METHODOLOGY A prospective cross-sectional study was carried out in B.P. Koirala Lions Centre for Ophthalmic Studies from April 2002-July 2003. All diagnosed cases of retinal vein occlusion were evaluated in detail for the presence of primary glaucoma. Detailed history was taken. Best corrected vi...

PURPOSE To report a case of acute retinal necrosis presenting as central retinal artery occlusion with cilioretinal sparing. METHODS Single interventional case report. The findings of the ophthalmic examination, MRI, blood parameters, biopsy results and clinical course are reported. RESULTS A forty two year old gentleman reporting sudden loss of sight, ophthalmic examination revealing uveit...

Diabetic retinopathy (DR) develops in a significant proportion of patients with chronic diabetes, characterized by retinal macular edema and abnormal retinal vessel outgrowth leading to vision loss. Chrysin, a naturally-occurring flavonoid found in herb and honeycomb, has anti-inflammatory, antioxidant, and anti-cancer properties. This study sought to determine the protective effects of chrysin...
