To evaluate the optical coherence tomography (OCT) findings in patients with solar retinopathy after watching a solar eclipse.
Complete ocular examinations and OCT were done in 4 patients presenting with acute solar retinopathy soon after observation of an eclipse. All 4 patients repeated the examinations about 1 month and 1 year after the first visit.
The symptoms and fundus findings were similar in all patients; all eyes were emmetropic. However, the OCT images were different in all patients, and the alterations were at different levels. The most evident alterations shown by OCT were: a reduction in the intensity of reflectiveness of the retinal pigment epithelium in 3 cases; intraretinal nonreflective spaces between the inner retinal layers in 2 cases; increased reflectiveness of the inner retinal layers in 2 cases, and a round hyperreflective formation in the vitreous just in front of the fovea in 1 case. All these OCT alterations disappeared after 1 month.
The retinal damage arising soon after exposure to sunlight showed many different aspects in the OCT images of the 4 cases examined. All retinal layers seemed to be altered, but these alterations disappeared after 1 month, and the OCT findings remained the same after 1 year.
评估日食后日光性视网膜病变患者的光学相干断层扫描（OCT）结果。
对4例日食观测后不久出现急性日光性视网膜病变的患者进行了全面的眼部检查和OCT检查。所有4例患者在首次就诊后约1个月和1年重复进行了检查。
所有患者的症状和眼底表现相似；所有眼均为正视眼。然而，所有患者的OCT图像均不同，且改变处于不同水平。OCT显示的最明显改变为：3例视网膜色素上皮反射强度降低；2例视网膜内层之间出现视网膜内无反射间隙；2例视网膜内层反射增强，1例在黄斑中央凹前方玻璃体中出现圆形高反射灶。所有这些OCT改变在1个月后消失。
在接受检查的4例患者的OCT图像中，日光照射后不久出现的视网膜损伤呈现出许多不同的表现。所有视网膜层似乎均有改变，但这些改变在1个月后消失，且1年后OCT结果保持不变。
