PURPOSE: To help the ophthalmologist who wishes to know the perfusion status o f the retina outside the macula, we determined whether clinical examination can predict capillary nonperfusion in diabetic retinopathy (DR) as accurately as flu orescein angiography (FA). DESIGN: Prospective observational case series. METHOD S: setting: Clinical practice. study population: Both eyes of 20 patients with c linically significant diabetic macular edema (CSME). observation procedure: The location of capillary nonperfusion was recorded following 90-diopter lens slit -lamp biomicroscopy, and the same measurements made on FA. main outcome measure : In the nasal and temporal quadrants of each eye, the clinical results were com pared with the “gold standard”FA. RESULTS: Most patients (84%) had definite p eripheral capillary nonperfusion. Biomicroscopy results were highly correlated w ith angiography, with only a few differences of clinical importance. CONCLUSIONS : Clinical examination can determine the location of capillary nonperfusion in D R with a high degree of accuracy.

目的:评价早期应用532倍频激光治疗视网膜静脉阻塞(renital veni occlusion,RVO)的疗效。方法:我院门诊及住院视网膜静脉阻塞患者67例67眼,经FVC-50相机荧光素眼底血管造影确诊后,经532倍频激光治疗,观察视力预后、眼底改变以及并发症情况。结果:治疗后,末次随访视力提高31眼,视力无明显变化30眼,视力下降6眼。激光治疗有效(无新生血管产生及新的视网膜无灌注区形成)62眼。结论:早期应用532倍频激光治疗,对视网膜静脉阻塞视网膜毛细血管无灌注区的消退、预防新生血管产生是一种有效、安全的治疗方法,临床疗效肯定。
