目的探讨生理性大视杯与早期青光眼的差异。方法侧重分析、研究盘沿的形态。研究对象分两组：（１）生理性大视杯：Ｃ／Ｄ＞０．６，视盘面积大于２．８ｍｍ２，随诊３～６年盘沿无改变，眼压及视野均正常，共５４例（８８只眼）。（２）早期青光眼：在随诊中有盘沿丢失或视野缺损，但Ｃ／Ｄ＜０．８者共６８例（８９只眼）。反映形态的指标有：（１）系列盘沿宽度；（２）视杯形态参数，即垂直Ｃ／Ｄ与水平Ｃ／Ｄ的比值。结果生理性大视杯与早期青光眼在形态上的差异：（１）前者视盘大；（２）前者的视杯为横椭圆形，后者视杯呈竖椭圆形；（３）前者的盘沿以下方最宽，上方次之，鼻侧、颞侧盘沿宽度较窄；后者因早期以下方盘沿丢失最常见，所以下方盘沿宽度较上方者窄或相同。结论视杯形态＋盘沿面积＋视盘面积的组合，在多因素判别分析的回代中符合率最高。
Objective To investigate the difference between physiological glaucoma and early glaucoma. The method focuses on the analysis of the morphology of the rim. Subjects were divided into two groups: (1) Physiological cup: C / D> 0.6, optic disc area greater than 2.8mm2, followed up for 3 to 6 years without change along the disk, intraocular pressure and visual field were normal, a total of 54 Example (88 eyes). (2) Early glaucoma: There are missing or missing visual fields during follow-up. However, there are 68 cases (89 eyes) with C / D <0.8. Reflect the morphological indicators are: (1) series of disc width; (2) cup morphological parameters, the vertical C / D and the level of C / D ratio. Results Physiological big eye cup and early glaucoma in the morphological differences: (1) the former optic disc large; (2) the former is a horizontal oval cup, the latter as the cup was vertical oval; (3) the former disk edge The following widest, followed by the top, nasal, temporal disc along the narrower width; the latter due to the early loss of the following side plate is the most common, so the lower disc along the width of the narrower or the same. Conclusions Depending on the combination of cup morphology, disc area and disc area, the highest coincidence rate was found in the multi-factor discriminant analysis.
