Changing trends in sympathetic ophthalmia

Sympathetic ophthalmia is a rare and potentially visually devastating bilateral panuveitis, typically following non-surgical penetrating injury to one eye. Three patients are presented where sympathetic ophthalmia developed after repeated vitreoretinal surgery. Prompt and effective management with systemic immunosuppressive agents permitted control of their disease and retention of good visual acuity in their remaining eye. Vitreoretinal surgery is an important risk factor in sympathetic ophthalmia. Informed consent for vitreoretinal surgery (especially in the re-operation setting) should now include the risk of sympathetic ophthalmia (approximately 1 in 800). Diverse clinical presentations are possible in sympathetic ophthalmia and any bilateral uveitis following vitreoretinal surgery should alert the surgeon to the possibility of sympathetic ophthalmia. Modern immunosuppressive therapy with systemic steroids and steroid-sparing agents such as cyclosporin A and azathioprine have improved the prognosis. This is particularly so in cases where early diagnosis is made and prompt and suitable immunotherapy is commenced.
