To present a case of occult macular dystrophy accompanying normal-tension glaucoma.
Observational case report.
Visual function and ophthalmoscopic and electroretinographic findings in a 56-year-old man suffering from gradually progressive photophobia and visual dysfunction were followed up over 4 years.
Best-corrected visual acuity was below 20/200, and intraocular pressures remained in the low teens in both eyes. A wedge-shaped visual field defect in the right eye, corresponding to the enlarged disk cupping, and a relative central scotoma in the left were detected. Ophthalmoscopy and fluorescein angiography detected no apparent abnormality at the macular region in either eye. Severely attenuated multifocal electroretinographic responses were recorded from only the central areas, with normal full-field responses.
Clinicians must look for additional pathologic conditions in patients with normal-tension glaucoma who have unexplained central visual dysfunction.
报告一例隐匿性黄斑营养不良合并正常眼压性青光眼的病例。
观察性病例报告。
对一名56岁逐渐出现畏光和视功能障碍的男性患者的视功能、检眼镜及视网膜电图检查结果进行了4年的随访。
最佳矫正视力低于20/200，双眼眼压维持在十几毫米汞柱的低值。右眼出现与视盘杯盘比扩大相对应的楔形视野缺损，左眼有相对中心暗点。检眼镜和荧光素血管造影均未发现双眼黄斑区有明显异常。仅在中心区域记录到严重衰减的多焦视网膜电图反应，全视野反应正常。
对于有无法解释的中心视功能障碍的正常眼压性青光眼患者，临床医生必须寻找其他病理状况。
