Autologous serum application in the treatment of Mooren's ulcer.

Background: Mooren's ulcer is a peripheral corneal ulceration of presumed autoimmune aetiology. Its clinical course and eventual prognosis is variable and usually these ulcers respond poorly to conventional therapy.

History And Signs: A 67-year-old male was referred to our hospital for a painful, red and tearing left eye after receiving debris. Slit-lamp examination revealed a 3.2 x 2.1 mm peripheral corneal ulcer, a diffuse thinning of the lateral limbus (between 3 o'clock and 5 o'clock) and some endothelial precipitates. The conjunctiva was severely congested. In the anterior chamber, cells (++) and fibrin were found.

Therapy And Outcome: We introduced an antibiotic, corticosteroid and cyclosporin therapy to treat the marginal corneal deficit caused by Mooren's ulcer. The patient did not respond to the initial treatment, but re-epithelialisation occurred and the corneal deficit improved after the introduction of autologous serum eye drops.

Conclusion: Autologous serum seems to be an effective supplementary therapy in Mooren's ulcer.
