Optic disk size in open-angle glaucoma: the Blue Mountains Eye Study
Healy PR; Mitchell PAmerican Journal of Ophthalmology 1999; 128: 515-517
PURPOSE: To compare optic disc size in eyes of subjects classified as normal with the eyes of subjects with open-angle glaucoma, ocular hypertension, or pseudoexfoliation syndrome in an older population-based sample. METHODS: The Blue Mountains Eye Study examined 3654 subjects. Vertical disc diameter was measured from stereoscopic disk photographs, and the authors used spherical equivalent refraction to correct for magnification. Analyses used all eyes in a general estimating equation model. RESULTS: Mean disc diameter was 1.556 mm in glaucomatous eyes, significantly different (p < 0.05) than normal eyes (1.506 mm) and eyes with ocular hypertension (1.494 mm) or pseudoexfoliation (1.501 mm). CONCLUSIONS: Patients with glaucoma have slightly larger optic discs than nonglaucomatous subjects.
