A 4-year-old female presented to us with inward deviation of the left eye since infancy. Anterior segment examination was normal in both eyes. Fundus of the right eye was normal. Indirect ophthalmoscopy of the left eye revealed narrowing of temporal arcade and temporal retinochoroidal coloboma [Figure 1]. The foveal area was involved in the coloboma. | Figure 1: Fundus image of the left eye shows narrowing of vascular arcade and temporal retinochoroidal coloboma

Very few cases of temporal retinochoroidal coloboma have been reported.[1],[2],[3] Typical inferonasal retinochoroidal coloboma occurs due to defective closure of embryonic fissure.[4] However, atypical colobomas are speculated to occur due to presence of accessory embryonic fissures, rotation of embryonic fissure, and developmental anomalies of neural ectoderm.[3],[5] It is important to recognize this rare entity.
