Abstract

Acquired night blindness is frequently due to vitamin A deficiency and may result from poor dietary intake, decreased absorption, or defects in vitamin A transportation.1 We report the first known instance of colon resection resulting in vitamin A deficiency, acquired night blindness, and isolated rod dysfunction with essentially normal cone function.

Report of a Case.  A 64-year-old woman complained of the inability to ambulate in dim light for 3 weeks. She had no night vision problems previously and, preceding ophthalmic examinations, had been normal except for operculated retinal holes. Her present ocular examination revealed a visual acuity of 20/20 OU. She had mild macular mottling but no peripheral retinal pigmentary changes. Concentric peripheral visual field loss was present in each eye.She had anemia and osteoporosis for 1 year before examination and underwent a partial colectomy for colon carcinoma 7 months before loss of night vision. Following surgery, she
