Biostereometrics In Ophthalmology For Measurement Of The Optic Disc Cup In Glaucoma

摘要: Glaucoma is a disease characterized by increased ocular pressure with optic nerve atrophy and loss of visual field or side vision which eventually leads to blindness. The surface the portion within eye, disc, becomes depressed its contours are altered. disc more cupped increasing progress disease. For measurement cup, retinal cameras can provide simultaneous stereo photographs taken through pupil. However, have be obtained at narrow angle due limit size dilated Our studies geometry show greater error in depth compared horizontal dimensions because this biological limit. Similarly, data for optimal conditions photography including aperture magnification been obtained. Since changes increase desease, photogrammetric techniques measuring relative cup developed. Both subsequent initial measured after being similarly oriented space. glaucoma has potential as useful technique wide clinical application.© (1980) COPYRIGHT SPIE--The International Society Optical Engineering.
