FP5 : Occult Optic Disc Pit Maculopathy In a Glaucomatous Disc

Dr.Pratyusha Ganne

Optic pits are congenital defects of the optic disc. Diagnosis of optic pit maculopathy is quite challenging in the absence of a clinically visible or optical coherence tomography proven pit. One such scenario is when there is advanced glaucomatous cupping. We present a 60 year old lady who presented with serous macular detachment in the right eye. She had advanced optic disc damage (cup:disc ratio=0.9) due to primary angle closure glaucoma. No disc pit was seen clinically and the rest of the fundus examination was normal. Optical coherence tomography (OCT) scans through the macula showed a serous detachment of the macula reaching upto the disc with outer retinal schisis along nasal edge of the detachment in the right eye. Scans through the disc showed a deep nasal cup and a cavitary defect in the disc stroma. There was a thin fenestrated membrane traversing the cup. These findings were absent in the left eye. Fluorescein angiography of both eyes did not reveal any source of leakage.
