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...
Background: Central retinal vein occlusion (CRVO) is the second most common retinal vascular disorder after diabetic retinopathy. In this study, we tried to examine the potentials of time-frequency methods for differentiating the eyes with CRVO. Materials and methods: Twenty patients with unilateral CRVO were included in this study. Their contralateral normal eyes were considered as the control...
BACKGROUND/AIM Retinal vein occlusion (RVO) is one of the most frequent ocular vascular diseases and leads to severe vision impairment. Colour Doppler imaging (CDI) is the first method which allows distinct evaluation of arterial and venous velocities in RVO. CDI is valuable for diagnosis of RVO and shows the effects of isovolaemic haemodilution. Patients with RVO were monitored by CDI for 1 ye...
Primary empty sella (PES) syndrome is a rare and benign condition usually with no symptoms, and, often revealed incidentally. But at times the manifests wide variable range of ocular endocrine features. Central retinal vein occlusion (CRVO) in itself cause blindness, its presence context primary even rarer. In this article, authors report case hypertensive man his late thirties presenting to me...
Human retina consists of repeating pattern of arteries and veins. This repeating pattern is known as Fractals. Fractal Dimension is the quantity which is to be determined for analyzing disorder in retina using fractal analysis. There are two disorders of retina which leads to complete vision loss. They are Occlusion and Diabetic Retinopathy. Occlusion is due to arteries crossing over vein leadi...
AIMS To evaluate the ocular axial length as a risk factor for development of central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO). METHODS Ocular axial lengths were measured, by A-scan ultrasonography, in 17 patients with CRVO and 41 patients with BRVO and compared with those of contralateral unaffected eyes and 66 age matched controls. RESULTS In 17 patients with ...
AIM To study the effect of superselective ophthalmic artery fibrinolysis as a treatment for central retinal vein occlusion (CRVO). METHODS Retrospective, university based single centre study. The charts of 26 eyes of 26 patients treated were reviewed. Among the 26 patients, there were nine cases of combined artery and vein occlusion, three cases of combined cilioretinal artery and CRVO, and 1...
introduction: retinal vein occlusion is a common vascular disorder disrupting vision. two basic types of rvo are branch retinal vein occlusion and central retinal vein occlusion (crvo). retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.rvo may be associated with atherosclerotic risk factors. we analyzed the role of 2 dimensional transthoracic...
We report a case of a patient with an impending central retinal vein occlusion (CRVO) with cilioretinal artery obstruction, which may help to understand the nature of the retinal hemodynamic changes associated with CRVO which shows direct evidence of arterial vasospasm, suggesting an increased contractility of retinal arteries. The clinical course, with initial retinal whitening along a ciliore...
AIMS To determine whether plasma homocysteine, methylene tetrahydrofolate reductase (MTHFR) C677T and factor II G20210A polymorphisms, factor VIII, and vWF are risk factors for central retinal vein occlusion (CRVO). METHOD Prospective comparison of 63 consecutive patients with central retinal vein occlusion and 63 age matched controls. Plasma homocysteine and vWF were estimated by ELISA, the ...
