183 first-degree relatives of glaucoma patients were photographed by a technician with non-mydriatic fundus camera in order to study the suitability of wide angle black-and-white fundus photographs in screening for glaucoma. The success rate of photography was 92%. The optic disc and retinal nerve fiber layer abnormalities were evaluated from the photographs by an ophthalmologist. 31 subjects (17%) were referred to further ophthalmological examinations. We found 6 (3%) new glaucomas. In addition, in 6 patients (3%) retinal nerve fiber layer defect was the only abnormality, 5 subjects (3%) showed a hemorrhage and 2 eyes had collateral vessels as a sign of asymptomatic venous stasis change at the optic disc. Only 1 of the 6 (17%) patients with glaucoma would have been found with tonometry alone. The results of this study indicate that non-mydriatic retinal camera is a useful tool in screening for glaucoma.
为了研究广角黑白眼底照片在青光眼筛查中的适用性，一名技术人员使用非散瞳眼底相机为183名青光眼患者的一级亲属拍摄了照片。摄影成功率为92%。一名眼科医生通过照片评估视盘和视网膜神经纤维层异常情况。31名受试者（17%）被转诊接受进一步眼科检查。我们发现了6例（3%）新发青光眼。此外，6例患者（3%）视网膜神经纤维层缺损是唯一异常，5名受试者（3%）出现出血，2只眼睛有侧支血管，提示视盘无症状性静脉淤滞改变。6例青光眼患者中仅1例（17%）仅通过眼压测量就能被发现。本研究结果表明，非散瞳视网膜相机是青光眼筛查的有用工具。
