AMAÇ: Metalik yabancý cisim maruziyeti sonrasý oluþan korneal yaralanmalarda lazer fotometri kullanarak ön kamara flare deðiþikliklerini deðerlendirmek.
GEREÇ VE YÖNTEM: Bir gözünde yabancý cisim yaralanmasý olan 54 hastanýn saðlýklý gözü karþýlaþtýrmalý, gözlemsel ve kesitsel bir çalýþmada incelendi. Flaredeki deðiþkenlik demografik özellikler, önceki maruziyetlerin öyküsü, korneal yabancý cismin yaralý korneadaki yeri ve penetrasyonuna göre analiz edildi.
BULGULAR: Korneal yabancý cisim gelen gözlerde ortalama flaremetre deðeri diðer kontrollere göre anlamlý derecede yüksekti (sýrasýyla, 11.35±14.17 ph/ms ve 6.30±3.81 ph/ms) (p=0.014). Daha önce birden fazla korneal yabancý cisim çýkarýlmasý öyküsü olan gözlerde, flaremetrenin ortalama deðeri diðerlerinden anlamlý derecede düþüktü (p=0.029).
TARTIÞMA: Korneanýn yabancý cisme maruz kalmasýyla flare deðeri artar. Bununla birlikte, daha önce birçok korneal yabancý cisme maruz kalma durumunda, flare deðeri muhtemelen korneanýn duyarsýzlaþtýrýlmasýndan dolayý nispeten düþük olabilir.

Anahtar Kelimeler: Korneal yabancý cisim, lazer flare fotometri; ön kamara reaksiyonu.

BACKGROUND: This study aims to use laser flare photometry to evaluate flare changes in patients following corneal damage from a metallic foreign body (FB).
METHODS: Foreign body injured eyes and the healthy fellow eyes of 54 consecutive patients were studied in this comparative, observational, cross-sectional study. Flare levels were analyzed according to demographics, history of previous exposures, foreign body location, and foreign body penetration into the injured cornea.
RESULTS: The mean flare value was significantly higher for the eyes with corneal foreign body injury compared to the fellow-control eyes (11.35±14.17 ph/ms and 6.30±3.81 ph/ms, respectively) (p=0.014). The mean flare values were significantly lower in eyes with a history of more than one previous corneal foreign body removal flare values than in other eyes (p=0.029).
CONCLUSION: Flare is increased by corneal foreign body exposure. However, eyes that experience multiple previous corneal foreign body exposures may show relatively low flare, probably due to corneal desensitization.

Keywords: Anterior chamber reaction, corneal foreign body; laser flare photometry.
