Congenital disc anomalies like optic disc coloboma or optic disc pit are rare occurrences. Coloboma involving disc or optic disc coloboma occurs due to defective closure of choroidal fissure, which can be unilateral or bilateral. These anomalies are discovered on routine examination or referred to as an open-angle glaucoma suspect. These anomalies can be asymptomatic or may present with visual field defects. Here we report a case of both eyes angle closure glaucoma with incidental finding of unilateral coloboma involving disc in the left eye. Optical coherence tomography of the optic nerve head showed peripapillary nerve fiber loss. Thus assessing such patients for diagnosis and the progression of visual field defects in managing glaucoma is quite challenging.
先天性视盘异常，如视盘缺损或视盘凹陷，较为罕见。累及视盘的缺损或视盘缺损是由于脉络膜裂闭合不全所致，可为单侧或双侧。这些异常在常规检查中被发现，或被视为开角型青光眼疑似病例。这些异常可能无症状，也可能伴有视野缺损。在此，我们报告一例双眼闭角型青光眼患者，偶然发现左眼存在单侧视盘缺损。视神经乳头的光学相干断层扫描显示视乳头周围神经纤维缺失。因此，评估此类患者以进行青光眼的诊断和视野缺损进展的管理极具挑战性。
