Automatic screening of Age-related Macular Degeneration (AMD) is important for both patients and ophthalmologists. The major sign of contracting AMD at the early stage is the appearance of drusen, which are the accumulation of extracellular material and appear as yellow-white spots on the retina. In this paper, we propose an effective approach for drusen segmentation towards AMD screening. The ...

Purpose To develop a proof-of-concept, computational method for the quantification and classification of fundus images in intermediate age-related macular degeneration (AMD). Methods Multispectral, unsupervised pattern recognition was applied to 184 fundus images from 10 normal and 36 intermediate AMD eyes. The imaging results of preprocessed, grayscale images from three modalities (infrared,...

Slit-lamp examination and stereoscopic fundus photography were found to be helpful in differentiating between physiological and glaucomatous cupping of the disc. Vertical ovalness of any cup in the disc should raise the suspicion of glaucoma, and the magnitude of the vertical cup: disc ratio is of particular significance.

Diabetic Retinopathy (DR) is a chronic progressive disease of the retinal microvasculature which is among the major causes of vision loss in the world. The diagnosis of DR is based on the detection of retinal lesions such as microaneurysms, exudates and drusen in retinal images acquired by a fundus camera. However, bright lesions such as exudates and drusen share similar appearances while being...

BACKGROUND The hallmarks of age related macular degeneration (AMD) are the subretinal deposits known as drusen. Current manual methods of drusen segmentation and quantification are laborious and subjective. The authors introduced a digital method and tested it for accuracy and reliability. METHODS Fourteen eyes with drusen were selected. The authors digitally reconstructed the macular backgro...

In aged people, the central vision is affected by Age-Related Macular Degeneration (AMD). From digital retinal fundus images, AMD can be recognized because of existence Drusen, Choroidal Neovascularization (CNV), and Geographic Atrophy (GA). It time-consuming costly for ophthalmologists to monitor images. A monitoring system automated photography reduce these problems. this paper, we propose a ...

UNLABELLED The aim of the study was to analyze the group of patients with optic disc drusen focusing on possible complications of this disease. MATERIAL AND METHODS In our group of patients, we examined 46 eyes of 23 patients with the suspicion of optic disc drusen during the period from May 2013 until January 2014. In all adult patients, we examined the anterior and posterior segment of the ...
