Clinical manifestations of inflammatory bowel disease (IBD) are not locally restricted to the gastrointestinal tract, and a significant portion of patients have involvement of other organs and systems. The visual system is one of the most frequently affected, mainly by inflammatory disorders such as episcleritis, uveitis and scleritis. A critical review of available literature concerning ocular involvement in IBD, as it appears in PubMed, was performed. Episcleritis, the most common ocular extraintestinal manifestation (EIM), seems to be more associated with IBD activity when compared with other ocular EIMs. In IBD patients, anterior uveitis has an insidious onset, it is longstanding and bilateral, and not related to the intestinal disease activity. Systemic steroids or immunosuppressants may be necessary in severe ocular inflammation cases, and control of the underlying bowel disease is important to prevent recurrence. Our review revealed that ocular involvement is more prevalent in Crohn’s disease than ulcerative colitis, in active IBD, mainly in the presence of other EIMs. The ophthalmic symptoms in IBD are mainly non-specific and their relevance may not be recognized by the clinician; most ophthalmic manifestations are treatable, and resolve without sequel upon prompt treatment. A collaborative clinical care team for management of IBD that includes ophthalmologists is central for improvement of quality care for these patients, and it is also cost-effective.
Core tip: Among all inflammatory bowel disease (IBD) patients, ophthalmic inflammatory disorders occur in 0.3% to 13.0% of cases, 1.6%-5.4% among the ulcerative colitis and 3.5%-6.8% among the Crohn’s disease patients. Since asymptomatic inflammation of ocular tissues may occur, a routine ophthalmic follow-up is recommended in all IBD patients, mainly before changes in IBD therapy because some drugs may cause ocular adverse effects. Patients with chronic or recurrent use of systemic corticosteroids should be warned of the risk of cataracts and glaucoma. Patient awareness of possible eye involvement is important in improving understanding of their disease and health outcomes, supporting early diagnosis, which will contribute to success of the treatment.
