Retinal microaneurysms in leukaemia.
THE purpose of this report is to describe the presence of microaneurysms in the retinae of patients who died with leukaemia. Although this type of lesion is most frequently observed in association with diabetes mellitis, it has, during recent years, been described clinically and/or histologically in association with a diverse variety of apparently unrelated entities. In a few instances the lesi...
متن کاملCorrelation of leaking microaneurysms with retinal thickening in diabetic retinopathy.
AIM To investigate the contribution of fluorescein angiographic leaking microaneurysms (leak-MA) versus non-leaking microaneurysms (non-leak-MA) to retinal thickening in diabetic retinopathy. METHODS A consecutive series of 38 eyes from 24 patients with diabetic retinopathy was included. Leak-MA and non-leak-MA in each eye were selected in pairs at corresponding topographic location. Leaking ...
متن کاملMicroaneurysms cause refractory macular edema in branch retinal vein occlusion
Intravitreal anti-vascular endothelial growth factor (VEGF) agents can treat macular edema (ME) in branch retinal vein occlusion (BRVO). However, refractory ME, the mechanism of which is not well elucidated, occurs frequently. Sixty-six eyes with ME secondary to BRVO were enrolled in this retrospective observational case-control study. Twenty eyes received a sub-Tenon's capsule injection of tri...
متن کاملRetinal Microaneurysms Detection using Local Convergence Index Features
Retinal microaneurysms are the earliest clinical sign of diabetic retinopathy disease. Detection of microaneurysms is crucial for the early diagnosis of diabetic retinopathy and prevention of blindness. In this paper, a novel and reliable method for automatic detection of microaneurysms in retinal images is proposed. In the first stage of the proposed method, several preliminary microaneurysm c...
متن کاملDetection of microaneurysms in retinal images using an ensemble classifier
This paper introduces, and reports on the performance of, a novel combination of algorithms for automated microaneurysm (MA) detection in retinal images. The presence of MAs in retinal images is a pathognomonic sign of Diabetic Retinopathy (DR) which is one of the leading causes of blindness amongst the working age population. An extensive survey of the literature is presented and current techn...
