笔者在体检中对我国16～18岁男性青年的视盘情况做了统计分析:计250正常人500只眼,其中视盘边界清晰者有449只眼(89.8％),具有乳头上膜者7眼(1.4％);视网膜具有有髓神经纤维者6眼(1.2％),具有睫状血管者(包括动脉和静脉)68眼(13.6％)。视盘上的血管数平均为20.79±2.93条。杯/盘比值(横径)≥0.6者有25眼(5％),其余475眼杯/盘比值均在0.6以下。此外对166眼的视杯形态作了观察并分作5型:ⅠⅡ型为漏斗型和圆柱型,计93眼(56％);其余3型视杯略有倾斜,计73眼(44％)。最后对视杯形态不同的原因略作讨论。
The author in the physical examination of our country 16 to 18-year-old male under the condition of the optic disc did a statistical analysis: 250 normal subjects 500 eyes, including clear disc boundary 449 eyes (89.8%), nipple with 7 eyes 1.4%). There were 6 eyes (1.2%) with myelinated fibers in the retina and 68 eyes (13.6%) with ciliary vessels, including arteries and veins. The average number of vessels on the optic disc was 20.79 ± 2.93. Cup / disk ratio (diameter) ≥ 0.6 were 25 (5%), the remaining 475 eye cup / disk ratio of 0.6 or less. In addition, the morphology of optic disc in 166 eyes was observed and divided into 5 types: type Ⅰ Ⅱ was funnel-shaped and cylindrical type, accounting for 93 eyes (56%); the other 3 types of optic cup slightly inclined, accounting for 73 eyes (44% . Finally, the reasons for the different forms of optic fiber slightly discussed.
