Abstract: A congenital anomaly, optic nerve pit is often associated with serous retinal detachment involving macula. Long standing serous detachment leads to outer retinal atrophy and decrease in visual sensitivity. Recently, spectral-domain optical coherence tomography (OCT) has been reported to demonstrate a communication between the optic nerve sheath and the subretinal space. Vitreous cavity is proposed as an alternate source of fluid for accumulation in the subretinal space. We imaged a patient with optic nerve pit with Spectralis OCT and report the findings seen including the presence of an area of peripapapillary retinal atrophy, due to the spontaneous resolution of associated long-standing retinal detachment.
