Ten patients (13 eyes) suffered from varying degrees of eclipse retinopathy during a solar eclipse on 16 February 1980. There was no correlation between severity of the fundus lesions and the visual acuity. In 8 of the 10 eyes available for follow-up 6/6 or better visual acuity was seen. Early fluorescein studies revealed microleaks in 3 eyes (2 patients) and masking of choroidal fluorescence in 1 eye; however, 1 to 3 weeks later these eyes showed only faint window defects. It is postulated that in mild to moderate lesions there is a transient retinal capillary spasm, producing oedema in anterior retinal layers. Fluorescein angiography in such patients reveals no abnormality or only masking of choroidal fluorescence. However, severe cases develop micropunctures in the tight junctions of the pigment epithelium, leading to microleaks, which are sealed within a short period.
1980年2月16日日食期间，10名患者（13只眼）出现了不同程度的日食性视网膜病变。眼底病变的严重程度与视力之间没有相关性。在可供随访的10只眼中，有8只眼的视力达到了6/6或更好。早期荧光素检查发现3只眼（2名患者）有微渗漏，1只眼有脉络膜荧光遮蔽；然而，1至3周后，这些眼仅显示轻微的窗样缺损。据推测，在轻度至中度病变中，存在短暂的视网膜毛细血管痉挛，导致视网膜前层水肿。此类患者的荧光素血管造影显示无异常或仅有脉络膜荧光遮蔽。然而，严重病例会在色素上皮紧密连接处出现微穿刺，导致微渗漏，这些微渗漏会在短时间内封闭。
