CONN SYNDROME PRESENTING AS CENTRAL RETINAL VEIN OCCLUSION.

PURPOSE: To describe a case of central retinal vein occlusion in a young patient presenting with symptomatic malignant hypertension because of Conn syndrome.

METHODS: Single interventional case report.

RESULTS: A 44-year-old man presented with a 1-day history of headache and vision loss in his right eye on a background of malignant hypertension. He was diagnosed with right central retinal vein occlusion. Further investigation of his malignant hypertension revealed Conn syndrome because of an aldosterone-secreting adenoma in the left adrenal gland.

CONCLUSION: This is the first reported case of Conn syndrome presenting as central retinal vein occlusion. Conn syndrome should be suspected in young patients with central retinal vein occlusion because it is a common cause of hypertension and carries significant cardiovascular risk if left untreated.
