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

Area of Science:

• Ophthalmology
• Immunology

Background:

• Mooren's ulcer is a rare, painful peripheral corneal ulcer of unknown autoimmune origin.
• It can lead to corneal opacity, degeneration, and irreversible vision loss if untreated.

Observation:

• A 60-year-old male presented with a classic, severe Mooren's ulcer in his right eye.
• The patient had a history of Mooren's ulcer in the left eye with complete vision loss.
• He experienced intense pain, redness, photophobia, and progressive vision decline.

Findings:

• The case presented as idiopathic, with no identifiable comorbid systemic conditions.
• Despite multiple treatments including tarsorrhaphy, amniotic membrane grafting, conjunctival flap, and scleral patch graft, the affected eye could not be permanently salvaged.

Implications:

• This case underscores the aggressive nature and poor prognosis of some Mooren's ulcer presentations.
• It highlights the limitations of current therapeutic interventions in preventing permanent vision loss.
• Further research into the idiopathic etiology and advanced treatment strategies for Mooren's ulcer is warranted.
