黄斑旁缺损1例

Paracentral Scotoma: A Case Report

摘要: 24岁男性，因体检时查见黄斑区结构异常前来就诊。眼底彩照示右眼黄斑颞上方可见一1.5 PD × 1 PD横椭圆形病灶，伴色素增生、脉络膜缺损及巩膜透见，黄斑中心凹结构部分保留。光学相干断层扫描(OCT)示病灶区视网膜脉络膜凹陷，神经上皮层变薄缺损，内界膜齿状凸起。视野检查示右眼鼻下方象限性视野缺损(与颞上病灶对应)。眼B型超声示眼球后壁视乳头颞侧可见局部凹陷(约1.3 mm × 4.0 mm)。诊断：右眼先天性黄斑缺损。

Abstract: A 24-year-old male presented with structural abnormalities in the macular region detected during a routine physical examination. Color fundus photography revealed a horizontally oval lesion measuring 1.5 PD × 1 PD in the superotemporal macula of the right eye, accompanied by pigment proliferation, choroidal defects, and visible sclera, with partial preservation of the foveal structure. Optical coherence tomography (OCT) showed a retinochoroidal depression in the lesion area, thinning and defects in the neurosensory layer, and a serrated elevation of the internal limiting membrane. Visual field testing demonstrated an inferonasal quadrant visual field defect in the right eye, corresponding to the superotemporal lesion. B-scan ultrasonography revealed a localized depression (approximately 1.3 mm × 4.0 mm) on the temporal side of the optic disc in the posterior wall of the eye. Diagnosis: Congenital macular coloboma of the right eye.
