Posterior Reversible Encephalopathy Syndrome in a Patient With Primary Hyperaldosteronism (Conn Syndrome)


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.
