Optical coherence tomographic features in a case of bilateral macular coloboma with strabismus

Purpose:To report the optical coherence tomography (OCT) findings in a patient with bilateral macular coloboma with strabismus. Methods:A 21-year-old male presented with macular coloboma in both eyes.Fundus photography, fundus fluorescence angiography (FFA) and OCT were performed. Results:Color fundus photography showed a sharply-demarcated, round macular defect, approximately 4×4 disc diameters with bare sclera at the base and pigment clumping in both eyes. FFA showed hypofluorescence at the macula corresponding to the size of the lesion bilaterally. OCT revealed a crater-like depression at the macula, demonstrating atrophic neurosensory retina, and an absence of retinal pigment epithelium (RPE) and choroid in the lesion. Conclusion:OCT can be a beneficial tool to confirm the diagnosis of macular coloboma.
