Delayed Correction of Hypotony Maculopathy in a Patient with Glaucoma and Thyroid-Related Orbitopathy

Abstract

Hypotony maculopathy is a condition that may result in visual deterioration from choroidal folds or optic disc edema. Optic disc edema can result from altered translaminar pressure gradients (lowered intraocular pressure, increased cerebrospinal fluid pressure, or increased orbital pressure). We report a case of bilateral optic disc edema in a patient with glaucoma and thyroid-related orbitopathy. The patient's disc edema was initially presumed to be secondary to her orbitopathy, but persisted after bilateral orbital decompression. Ultimately, disc edema and choroidal folds in the right eye resolved after trabeculectomy revision and an increase in intraocular pressure. This case serves as a reminder of the causes of optic disc edema and demonstrates delayed reversal of hypotony maculopathy.
