[Treatment of fungal keratitis by penetrating keratoplasty].

BACKGROUND: Fungal keratitis is basically treated by medications. Several cases of fungal keratitis were reported around the world to have been treated successfully by corneal graft--penetrating keratoplasty (PKP). Studies have shown that PKP is a useful treatment, preserves eye globe integrity, and rehabilitates vision in patients with advanced fungal keratitis. AIM: To study the use of penetrating keratoplasty for the treatment of severe fungal keratitis that could not be cured by antifungal medication. METHODS: The authors conducted a retrospective analysis of all cases (five cases) of severe fungal keratitis treated and followed-up at the Department of Ophthalmology, Soroka University Medical Center during 2007 and 2008, in which therapeutic PKP was performed. There were one male and 4 females. The age range was between 27 and 78 years. The follow-up period ranged from 4 to 15 months. RESULTS: Corneal graft remained clear during follow-up in most patients. There was no recurrence of fungal infection and the visual acuity ranged from counting fingers (FC) from 50 cm to 6/36. Complications in some patients included graft rejection in one patient with re-graft which remained clear during follow-up period of 6 months, another patient had a minimal partial graft rejection and incipient cataract which didn't necessitate further intervention. DISCUSSION AND CONCLUSIONS: PKP is an effective treatment for fungal keratitis that does not respond to antifungal medication. Early surgical intervention before deterioration is recommended.
