Corneal complications of rheumatoid arthritis.

PURPOSE OF REVIEW: Rheumatoid arthritis (RA) is an autoimmune disease that primarily affects the joints. Extra-articular manifestations (EAMs) are common and may affect up to 40.6% of patients. Ocular EAM can occur in 39% of the patients. The cornea is involved by different pathogenic mechanisms and corneal disease varies from mild symptoms to severe corneal ulceration and melting with visual loss. Severe corneal involvement is associated with increased mortality in RA patients. We aimed to review the prevalence, mechanisms, management and overall impact of corneal involvement in RA patients.

RECENT FINDINGS: Corneal involvement is frequent among RA patients. With the wider use of systemic immunosuppression, in particular the disease-modifying antirheumatic drugs (DMARDs), and with improvement of surgical techniques, spontaneous and surgery-related corneal ulceration and melting is becoming less common. However, RA patients are still at risk and should be carefully managed.

SUMMARY: RA-related corneal complications are associated with a decreased quality of life and poor ocular and systemic prognosis. Prompt recognition and a multidisciplinary approach involving topical ophthalmic management and systemic immunosuppression are the key factors to maintain ocular integrity and avoid a lethal outcome.
