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.
