Reversal of poorly controlled glaucoma on diagnosis and treatment of hypothyroidism

Hypothyroidism was diagnosed in a 62-year-old woman with poorly controlled primary open-angle glaucoma, including a disc hemorrhage and a documented arcuate scotoma. After 1 year of thyroxine therapy the glaucoma was easily controlled, pilocarpine treatment was stopped and the visual fields were completely normal. To our knowledge this is the first report in the modern literature of reversal of open-angle glaucoma with treatment of hypothyroidism.
