Hypotonic Maculopathy

Hypotonic maculopathy is a condition in which chorioretinal folds develop in the posterior pole of patients with chronically low intraocular pressure (usually lower than 5 mmHg). Fundus abnormalities also include papilledema and vascular tortuosity.

It usually occurs after anti-glaucoma surgery or when perforating eye injuries are sustained. Young age, myopia, primary filtering surgery, systemic illnesses and elevated preoperative intraocular pressure have been found to be associated with hypotonic maculopathy.
