Abstract

Background: Optic disc pit (ODP) is a congenital anomaly characterized by indented area of the optic nerve head most likely originating from the incomplete closure of the superior edge of the embryonic fissure. Maculopathy can occasionally complicate this anomaly as intra-retinal and sub-retinal fluid at the macula. In result, maculopathy is associated with a poor visual prognosis due to a serous macular detachment, formation of macular hole, or atrophy of the retinal pigmented epithelium. In this case series, we report of three patients with unilateral ODP.

Case report: We attempted to analyze the morphologic changes seen in the ODP and evaluate patients with a complete ophthalmologic evaluation, fundus color photography, spectral-domain optical coherence tomography (SD-OCT) scanning, and magnetic resonance imaging (MRI) of globe and orbit. Magnetic resonance imaging scan was done for optic disc diameter (ODD) and optic nerve sheath diameter (ONSD).

Conclusion: We noticed that in the patient who presented with neurosensory detachment in the macula, the ONSD is larger than in the fellow eye and is larger than the remaining two patients with ODP and without neurosensory detachment of the retina.
