متن کاملAutomatic Optic Disc Center and Boundary Detection in Color Fundus Images
Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...

متن کاملA new digital optic disc stereo camera: intraobserver and interobserver repeatability of optic disc measurements.
AIMS To investigate the intraobserver and interobserver repeatability of optic disc measurement using a new digital optic disc stereo camera. METHODS 112 consecutive new patients presenting to a glaucoma service had dilated optic disc photography performed using a new digital stereo camera (Discam, Marcher Enterprises Ltd, Hereford). The images were analysed by two masked observers using a st...
متن کاملProliferative diabetic retinopathy. Regression of optic disc neovascularization after retinal photocoagulation.
Photocoagulation is an accepted method of local treatment for proliferative diabetic retinopathy. It has been shown that 73 25 per cent. of eyes with proliferative diabetic retinopathy have new vessels on the optic disc at the initial visit (Taylor and Dobree, I970). These vessels cannot be treated directly by photocoagulation. Aiello, Beetham, Balodimos, Chazan, and Bradley (I969) treated all ...
