Introduction: Macular colobomas are solitary, well circumscribed, punched-out, crater-like le-sions. They are usually bilateral and show various systemic associations.
Case presentation: A 27-year-old female presented with painless diminution of vision in her left eye since birth without any family history of this condition. On ophthalmological examina-tion, the best corrected visual acuity (BCVA) was 20/20 and 20/200 in the right and left eye, re-spectively. A well-defined, round, crater-like defect was seen in the macula of the left eye, with an unremarkable right eye. The optical coherence tomogram (OCT) showed a deep crater with absent retinal pigment epithelium and choroid in this region.
Conclusion: Macular scars, such as those caused by toxoplasmosis or retinal dystrophies, can mimic this condition, and OCT can differentiate it with a few characteristic features.
