应用微机图象处理系统对１２９眼有神经上皮层脱离的中浆患眼眼底荧光血管造影负片进行分析处理，以视盘面积为单位测量早期及晚期渗漏斑面积、以视盘直径为单位测量渗漏点及晚期渗漏斑边缘到黄斑中心凹最近距离。视力与晚期渗漏斑大小呈显著负相关（Ｐ＜０．０１），与晚期渗漏斑边缘到黄斑中心凹最近距离呈显著正相关（Ｐ＜０．０１）。再按炊烟型和墨渍型渗漏比较视力和上述四个观测值，两型间仅渗漏点到黄斑中心凹距离有异差（Ｐ＜０．０５），炊烟型渗漏点较近黄斑中心凹。
Application of computer image processing system on 129 eyes with neural epithelial detachment in the eyes of the fundus fluorescein angiography negative film analysis and analysis of the optic disc area as the unit to measure early and late leakage area, measured by disc diameter as a unit of leakage Point and late edge of the leak to the macular foveal nearest distance. Visual acuity was significantly negatively correlated with the size of late leak (P <0.01), and positively correlated with the shortest distance from the edge of late leak to macular fovea (P <0.01). According to the comparison of visual acuity of smoke-type and ink-type leakage and the above-mentioned four observations, there was a significant difference (P <0.05) in the distance between leakage point and macular fovea between the two types, Fovea.
