Objective To investigate the features of optic disc formation and retinal nerve fiber layer(RNFL) changes in primary open-angle glaucoma with myopia (M-POAG). Methods On 63 eyes of 38 patients with M-POAG were imaged of the fundus,and were evaluated with the microcomputer image analyser,and were compared with the simple POAG　(S-POAG)　eyes. Results Variant features of the optic disc and RNFL atrophy were found in this M-POAG eyes.The shapes of the optic disc were revealed to be vertically or horizontally oval,obliquely inserted and irregular,the color of the most of optic disc was pallor.The pattern of glaucomatous cupping was saucer-like (28.6%),vertical (25.4%),oblique (23.8%),pot-like (9.5%),and focally or concentrically cupped.The quotient of the neuroretinal rim area and horizontal C/D ratio were significantly lower than those in S-POAG eyes (P lt;0.05,P lt;0.001).The focal point of the optic disc excavtions tended to be inferior.Most of the incidence in the focal atrophy of RNFL was located inferiorly,and the diffuse atrophy of RNFL was correlated positively with middle or late high-myopia POAG eyes (P＜0.005). Conclusion The variant features of the optic discs,glaucomatous cupping and RNFL atrophy formation in M-POAG eyes found in this series might be helpful in clinical diagnosis. (Chin J Ocul Fundus Dis,2000,16:81-84)
