RetCam image analysis of optic disc morphology in premature infants and its relation to ischaemic brain injury.
AIMS To assess optic disc characteristics in premature infants with and without ischaemic brain injury and to evaluate the role of optic disc morphology in dating the injury. METHODS RetCam fundal images, cranial ultrasounds and magnetic resonance imaging (MRI) of 109 premature infants were analysed. The study cohort was divided into subgroups depending on the presence or absence of periventr...
متن کاملOptic disc morphology and NAION.
Non-arteritic anterior ischaemic optic neuropathy (NAION) is a widespread visually disabling disease in the middleaged and elderly population. Based on clinical observations by Hayreh, Beck, Savino and others, a low cup/disc diameter ratio and a small optic disc have been described to be structural factors associated with the disease. The physiological correlation between disc size and cup/disc...

متن کاملOptic disc morphology in pigmentary glaucoma.
AIM To evaluate the morphology of the optic nerve head in eyes with pigmentary glaucoma. METHODS Colour stereo optic disc photographs of 62 patients with pigmentary glaucoma and 566 patients with primary open angle glaucoma were morphometrically evaluated. By prestudy selection, mean visual field defect and neuroretinal rim area were not significantly different between the two groups (p = 0.8...
متن کاملMathematical Morphology based Optic Disc Detection in Retinal Fundus Images
Optic disc segmentation is a prerequisite in automatic analysis of retinal disease in color fundus images. In this paper, an algorithm for detection of optic disc (OD) in fundus images is presented. Mathematical morphology is used for segmentation of candidate optic disc region, followed by determining its center and approximating the circular optic disc boundary using circular model. Proposed ...
