【摘要】 <正> 糖尿病性视网膜病变(简称DR)是糖尿病引起视力障碍原因之一。在欧美其致盲率约占6～8%,为失明原因之首。近年在我国糖尿病及糖尿病所致的DR也有增加的趋势。因此对糖尿病性视网膜病变的研究已成为眼科的重要课题。DR时引起的视力改变以糖尿病性黄斑症为多。夏德昭等从视力性质分析观点将视更多还原

【Abstract】 The state of fixation in 60 diseased eyes of diabetic retinopathy we-re examination The results as following: 1. The DR consists of both the central and eccentric fixation. Theformer has 45 eyes within 60 eyes, that is 75%; The latter being 15eyesis 25%. The simple form in the central fixation constitute 91.11%, The-he simple form DR being mainly in the contral fixation is distributedover Ⅰ--Ⅳ phases. The prolifertive form DR being principally in theeccentric fixation is scattered over Ⅲ--Ⅵ phases. 2. Visual acuity of DR: The central fixation X±SD: 0.5±0.3; Theeccentral fixation X±SD: 0.1±0.08. Deviation of color sensation: Thecentral fixartion X±SD: 65.86±84.73. The eccetic fixation X±SD: 199±87.83. Amplitude of b-wave in F-ERG: Dark adaptability: The central fixation X±SD: 324±69.50uv; The eccentic fixation X±SD: 200±100uv. Light adaptability: The central fixation X±SD: 87±85.70uv; eccentric fixation X±SD: 48±35uv, As mentioned above, they express thatthe value of b-wave amplitude of eccentric fixation are lower更多还原
