    Right eye showing grade 5 retinochoroidal coloboma inferior to the optic disc, with punched out appearance and choroidal vessels at base. Normal fundus of left eye. A 37-year-old woman presented for a routine check-up. Her visual acuity was 20/20 bilaterally. The anterior segment of both eyes and the posterior segment of the left eye were normal. Right-eye ophthalmoscopy revealed an isolated grade 5 retinochoroidal coloboma of approximately 1.5 disc diameters inferior to the optic disc. The remainder of the ocular and systemic examination was within normal limits. There was no history of trauma or congenital infections. Differential diagnoses of posterior staphyloma and congenital toxoplasmosis were excluded on the basis of history, laterality, clinical presentation, and investigations. A prophylactic barrage laser was performed around the coloboma, and the patient was kept on interval monitoring for subsequent development of retinal detachment.
