Multifocal posterior uveitis in Crohn's disease.

Purpose: To report a case of rare posterior eye manifestation of Crohn's disease preceding recurrence of inflammatory bowel disease.
Methods: Case report with ophthalmoscopic findings, fluorescein/indocyanin green angiograms, automated perimetry and multifocal-ERG.
Results: The perimetry revealed absolute and relative scotomas corresponding to multifocal inflammatory lesions in the retina and choroid, reduced a/b amplitudes in multifocal-ERG and hypofluorescent dots in angiography. Under oral prednisolone visual defects, ophthalmoscopic and angiographic findings resolved, while a/b amplitudes remained mildly reduced. The ocular changes occurred without systemic hypertension and were followed by a new episode of intestinal symptoms.
Conclusion: Multifocal inflammatory lesions in the retina and choroid in patients with Crohn's disease may occur and may precede a recurrent intestinal episode. Crohn's patients should be carefully followed up in collaboration with internal medicine specialists.
