 A case of optic disc coloboma with maculopathy: A: Cropped Optos image of the posterior pole of a 24-year-old girl shows a bowl-shaped inferior excavation with well-defined borders (white arrow) suggestive of optic disc coloboma with an additional choroidal coloboma inferior to it (red arrow). B: OCT scan image passing through the fovea shows a normal foveal contour without subfoveal subretinal fluid. C: OCT scan image passing through the serous retinal detachment. The serous retinal detachment is seen communicating directly with the optic disc coloboma (white arrow). Outer nuclear layer thinning is noted (yellow arrow) with multiple hyperreflective dots noted within and on the under surface of the neurosensory detachment (red arrow). D: OCT scan through the optic disc coloboma margin shows the schitic marginal intercalary membrane (white arrow) and the communication between the sub intercalary membrane space inside the coloboma and the subretinal space outside the coloboma (red arrow)
