Treating Mooren's Ulcer - Squeezing Water From a Stone.

Mooren's ulcer, a rare ophthalmic disease, presents clinically as a painful, chronic, peripheral corneal ulceration of unknown etiology with some autoimmune origin evidence. It begins with an intense limbal inflammation, leaving behind an opaque cornea. If left untreated, progressive damage and corneal degeneration can lead to permanent loss of vision. Herein, we present a classic case of Mooren's ulcer in the right eye of a 60-year-old male patient with no known comorbid condition. No underlying systemic disorder being the rarity in our case, the cause remains idiopathic. The patient was previously diagnosed with having Mooren's ulcer in his left eye 10 years ago. Despite multiple topical treatments and surgical interventions, there was a complete loss of vision. He presented exaggerated manifestations, including pain, redeye, watery eye, photophobia, and the progressive decline of vision. A combination of multiple pharmacological and surgical interventions, including lateral tarsorrhaphy, amniotic membrane grafting, conjunctival flap, and scleral patch graft, was tried to ameliorate the affected eye but failed to salvage the eye permanently.
