Clinical investigation of central retinal dysfunction in two cases of solar retinopathy.
Two patients were examined for best corrected visual acuity (VA), fundus inspection, visual fields, multifocal electroretinography (mfERG) with a stimulus pattern of 241 hexagons and, at follow-up, also with optical coherence tomography (OCT).
At the initial examination, mfERG revealed central retinal dysfunction, which had improved by the time of follow-up. In Case 1, a foveal oedema regressed over time, although VA remained slightly reduced. In Case 2, OCT showed spots of increased reflectivity corresponding to the patient's symptoms.
Central retinal dysfunction due to solar retinopathy may improve over time. However, structural and functional changes may persist. This report illustrates that mfERG and OCT are useful tools for objective documentation of the pathology in solar retinopathy.
对两例日光性视网膜病变患者的视网膜中央功能障碍进行临床研究。
对两名患者进行了最佳矫正视力（VA）、眼底检查、视野检查、采用241个六边形刺激模式的多焦视网膜电图（mfERG）检查，并且在随访时还进行了光学相干断层扫描（OCT）检查。
在初次检查时，mfERG显示存在视网膜中央功能障碍，到随访时有所改善。在病例1中，尽管视力仍略有下降，但黄斑水肿随时间消退。在病例2中，OCT显示与患者症状相对应的反射率增加斑点。
日光性视网膜病变所致的视网膜中央功能障碍可能会随时间改善。然而，结构和功能改变可能会持续存在。本报告表明，mfERG和OCT是客观记录日光性视网膜病变病理情况的有用工具。
