Choroidal coloboma is characterised by poor embryonic development of chorioretinal structures and is of different types. We present a case of choroidal coloboma where the retinal pigment epithelium was present, clinically and on imaging, but rest of the structures were poorly formed. This observation suggests that in some cases, fusion of the fetal cleft may occur aberrantly, resulting in an aborted choroidal coloboma.
脉络膜缺损的特征是脉络膜视网膜结构胚胎发育不良,且有不同类型。我们报告一例脉络膜缺损病例,该病例在临床和影像学上视网膜色素上皮存在,但其他结构发育不良。这一观察结果表明,在某些情况下,胎儿裂孔可能异常融合,导致不完全性脉络膜缺损。
