Abstract
Most glaucomas are primary in nature. However, many adult and childhood glaucomas are secondary, and they require systemic evaluation to pick up associated systemic disease. Conditions such as nocturnal hypotension and sleep apnea may contribute to glaucomatous progression, whereas neurologic diseases may mimic normal tension glaucoma based on disc appearance. This review highlights those conditions in which a focused systemic work-up can improve glaucoma management and potentially discover life-threatening disease.
