Posterior reversible encephalopathy syndrome (PRES) is an uncommon manifestation of severe hypertension. PRES most commonly manifests with headache, confusion, and vision loss, and typically, these symptoms are reversible. We present a case of a patient with chronic poorly controlled hypertension in whom PRES was the initial presentation that prompted evaluation for secondary hypertension due to primary hyperaldosteronism (i.e., Conn syndrome). The patient had a right homonymous hemianopsia due to ischemic infarct after PRES. To the best of our knowledge, this is the first case of homonymous hemianopsia as a primary manifestation of Conn syndrome to be reported in the English language ophthalmic literature.
