Abstract

Paracentral acute middle maculopathy (PAMM) is a condition characterized by ischemia affecting the deep capillary plexus layer of the macula, often resulting in a paracentral visual scotoma. PAMM has been reported in association with retinal vascular diseases or as an isolated phenomenon in young and healthy individuals. There is currently no treatment for PAMM. We report a case in which sublingual nitroglycerin reversed developing visual scotomas, or blind spots, in a patient with known recurrent episodes of PAMM. This case describes a male patient with previously documented evidence of PAMM in both eyes following episodes of extreme physical activity or dehydration. These episodes would often last days without ultimate resolution. After one such occurrence in his right eye, the patient was treated with a sublingual nitroglycerin tablet immediately after the development of new visual scotomas. The patient's visual symptoms improved within minutes of administering sublingual nitroglycerin, and completely resolved within hours.
