The purpose of this study is the present clinical evaluation of 21 patients (number of affected eyes--33), who watched eclipse of the sun on 12 October 1996. All patients had general ophthalmic examination with emphasis on visual acuity, visual field, Amsler test, fluorescein angiography and fundus appearance. Eleven out of 21 patients had at least one follow up examination (number of affected eyes--17). None of the patient received any treatment. All patients revealed tiny, central scotomata--positive Amsler test and decreased visual acuity on the first visit; reading Snellen chart could be improved in all patients by adequate head tilt or eye movement (improvement up to 3 Snellen chart lines). No signs of retinopathy were observed in two eyes with uncorrected refractive error and one amblyopic eye. After 7-8 weeks the visual acuity was decreased to 5/30 in two eyes and to 5/10 in ten eyes. In all those eyes persisted a tiny, central scotoma. Looking at the eclipse of the sun in spite of using primitive eye protection may cause irreversible retinal damage. Return of visual acuity to 5/5 does not always imply complete recovery because of persistent central scotoma.
本研究旨在对21例患者（患眼33只）进行临床评估，这些患者于1996年10月12日观看了日食。所有患者均接受了全面的眼科检查，重点包括视力、视野、阿姆斯勒表检查、荧光素血管造影和眼底表现。21例患者中有11例至少接受了一次随访检查（患眼17只）。所有患者均未接受任何治疗。所有患者初诊时均表现为微小的中心暗点、阿姆斯勒表检查阳性及视力下降；通过适当的头部倾斜或眼球运动，所有患者阅读斯内伦视力表的能力均可得到改善（提高达3行斯内伦视力表）。在2只未矫正屈光不正的眼睛和1只弱视眼中未观察到视网膜病变迹象。7 - 8周后，2只眼的视力降至5/30，10只眼的视力降至5/10。在所有这些眼中，均持续存在微小的中心暗点。尽管使用了原始的眼部防护措施，但观看日食仍可能导致不可逆的视网膜损伤。视力恢复到5/5并不总是意味着完全恢复，因为中心暗点可能持续存在。
