黄斑缺损是一种罕见的眼部疾病,影响约0.5-0.7/10,000的活产。黄斑缺损表现为界限分明的萎缩性病变,在眼底检查时可能会影响一只眼睛或两只眼睛。这是一例33岁的男性患者,他从小就出现左眼视力不佳的病史。他有左眼感觉性外斜视(XT)的斜视手术史。双眼眼前节检查正常,而双眼眼底检查显示黄斑双侧脉络膜视网膜病变,左眼(OS)大于右眼(OD),代表双侧脉络膜视网膜缺损。先天性结肠瘤是一种罕见的眼部疾病,可导致视力的非进行性下降。光学相干断层扫描(OCT)是诊断和描述黄斑缺损的首选模式。
Macular coloboma is a rare eye condition that affects around 0.5-0.7/10,000 of live births. Macular coloboma appears as a well-demarcated atrophic lesions that could affect one eye or both eyes on fundus examination. This is a case of a 33-year-old male patient who presented to the outpatient clinic with a history of poor vision in the left eye since childhood. He had a history of strabismus surgery for sensory exotropia (XT) in the left eye. Anterior segment examination of both eyes was normal while the fundus examination of both eyes revealed bilateral chorioretinal lesions in the macula which was larger in the left eye (OS) than the right eye (OD), representing bilateral chorioretinal coloboma. Congenital coloboma is a rare eye condition that leads to non-progressive decrease in visual acuity. Optical coherence tomography (OCT) is the modality of choice in diagnosing and describing macular coloboma.
