The authors describe a case of bilateral pattern dystrophy of the retinal p
igment epithelium in a man with Crohn's disease. The patient was examined e
very 6 months over a follow-up of 30 months. The right eye presented a macr
oreticular dystrophy while in the left eye a butterfly pattern dystrophy wa
s diagnosed. During the follow-up period the retinal lesion changed; in the
right eye the lesion increased in size, while in the left eye the morpholo
gy of the lesion passed from the butterfly to Sjogren's type. This report a
dds a new ocular manifestation of Crohn's disease, emphasizing the importan
ce of the ophthalmological follow-up in the recognition of posterior segmen
t complications associated with this inflammatory bowel disease. Copyright
