Background: An adolescent boy aged 17 years presented with sudden onset of visual impairment, which was rapidly diagnosed as bilateral anterior uveitis by an ophthalmologist. A systemic review noted episodes of nonbloody diarrhea, weight loss of 3 kg and a diminished appetite during the previous 10 months. The patient's family history revealed an older brother with Crohn's disease.
Investigations: Visual acuity test, slit-lamp examination, ophthalmologic fundoscopy and endoscopic evaluation of the upper and lower gastrointestinal tract with biopsy.
Diagnosis: Multifocal Crohn's disease, involving the terminal ileum and cecum, in addition to the stomach and duodenum.
Management: Treatment with topical corticosteroids, in the form of ophthalmic drops and oral budesonide ileal-release capsules. Once remission was achieved, it was maintained with mercaptopurine.
