Can grey crescent prevent macular detachment in case of optic disc pit? A case report and hypothesis

We here describe a case with bilateral optic disc pit and bilateral assymetrical grey crescent, its ocular coherence tomography findings and the associated unilateral maculopathy in the eye with incomplete crescent. The interesting observation is that the eye in which the grey crescent encompassed the optic pit did not have any maculopathy in contrast to the other eye which had macular retinoschisis and macular retinal detachment with smallar grey crescent not encompassing the pit. Presence of grey crescents around the optic disc pits may prevent the occurance of associated maculopathy, similar to the intrenal temponade and laser done to treat the maculopathy.
