OBJECTIVE: To investigate the sensitivity of Heidelberg Retina Tomography (HRT-II) parameters on the early optic nerve change of glaucoma head. DESIGN: Cross-sectional study. PARTICIPANTS: Twenty-one patients (36 eyes) with big cupped disc (C/D ≥ 0.7) and twenty-seven patients (31 eyes) with early glaucoma (C/D ≥ 0.7, MD≤ 3dB) were studied. METHODS: All patients underwent visual field and HRT-II examination to get parameters of optic nerve head. T test was used to compare the parameters of optic disc between big cupped disc and early glaucoma. Main outcome measures: HRT II parameters included disc area, cup area, rim area, cup volume, rim volume, C/D area ratio, mean cup depth, maximum cup depth, cup shape measure, height variation contour, mean RNFL thickness and RNFL cross sectional area. RESULTS: Statistics analysis with T test (t = 2.247-3.714, P = 0.000-0.028) showed there were significant differences of rim area, rim volume, mean retinal nerve fiber layer thickness, sectional area of retinal nerve fiber layer between big cupped disc and early glaucoma. CONCLUSIONS: We can pay attention to those parameters with HRT-II to distinguish patients with big cupped disc and early glaucoma. LA: Chinese
