目的:探讨视盘形态分析在原发性开角型青光眼早期诊断中的作用。方法:选取72例视乳头杯盘比在0.5~0.8之间的受检者进行视力、裂隙灯、直接检眼镜检查、测眼压及24h眼压曲线、检影验光,并行房角镜、电脑视野和光学相干断层成像(optical coherence tomography,OCT)检查,并对上述检查结果进行分析。结果:视盘形态正常者仅有10例眼压在可疑范围,视野、OCT检查未见异常;而视盘形态异常者中眼压、视野及OCT异常者占较大比例。结论:视盘形态在原发性开角型青光眼早期诊断中是一敏感因素。

·AIM:To investigate the value of optic disc formation analysis in early diagnosis of primary open angle glaucoma.·METHODS:Seventy-two examinees whose cup-disc ratio were 0.5-0.8 underwent ophthalmic routine examina-tions,gonioscopy,perimetry and optical coherence tomography(OCT),and the results were analyzed.·RESULTS:The intraocular pressure of only 10 exami-nees with normal optic disc formation fell on the "suspicious" range.All the examinees with normal optic disc formation got normal results in perimetry and OCT.A big proportion of examinees with abnormal optic disc formation got abnormal results in intraocular pressure measurement,perimetry and OCT.·CONCLUSION:The optic disc formation is a sensitive factor in early diagnosis of primary open angle glaucoma.·
