Clinical and Microbiological Characteristics of Bacterıal Keratitis in Our Region

Abstract

Objectives: To review the clinical and microbiological characteristics of bacterial keratitis in our ophthalmology department. Materials and methods: A retrospective analysis of the hospital records of 32 patients presenting with bacterial keratitis were analysed from January 2005 to January 2007. Results: The mean age of the patients were 53, 6±24, 9 and 52, 25% (18) were older than 65 years. Presenting mean visual acuity was 0, 085±0, 185 log mar and mean final visual acuity was 0, 145±0, 299 log mar. As a major ocular risk factor, trauma was defined in 15, 7% ( 5) patients. An organism was defined in 34, 3% (11) patients. 73% (8) and 27% (3) of the isolates were Gram positive and Gram negative bacteria, respectively. Streptococcus species were the most common isolates (7, 64%). Most of the bacterial isolates remained sensitive to currently availableantibiotic preparations. 93, 7% (30) of keratitis healed with therapy and 86, 6% (26) of patients had visual acuity the same or better than the level at admission. 6, 3% (2) had very poor visual outcome and keratoplasty were performed. Conclusion: Most of our patients with bacterial keratitis were healed with appropriate treatment. Trauma was the most important ocular risk factor. Elder population has an increased risk of developing keratitis.©2008, Firat University, Medical Faculty.

Yöremizdeki Bakteriyel Keratitlerin Klinik Ve Mikrobiyolojik Özellikleri

Öz

Amaç: Oftalmoloji kliniğimizdeki bakteriyel keratitlerin klinik ve mikrobiyolojik özelliklerini incelemek. Gereç ve Yöntem: Ocak 2005 ve Ocak 2007 yılları arasında bakteriyel keratit tanısı alan 32 hastanın kayıtları retrospektif olarak incelendi. Bulgular: Hastaların ortalama yaşı 53, 6±24, 9 ve %52, 25 (18)' i 65 yaşından daha yaşlı idi. İlk geliş görme keskinlikleri 0, 085±0, 185 log mar, son görme keskinlikleri ise 0, 145±0, 299 log mar arasında idi. En önemli oküler risk faktörü olarak %15, 7 (5) hastada travma saptandı. %34, 3 (11) hastada organizma tanımlandı. İzolatların sırasıyla %73 (8)'ü Gram pozitif, %27 (3)'si Gram negatif idi. Streptococcus türleri en yaygın izolat idi (7, %64). İzole edilen bakterilerin çoğu günümüzde yaygın olarak kullanılan antibiyotiklere duyarlı idi. %93, 7 (30) keratit tedavi ile iyileşti ve %86, 6 (26) hastada görme keskinliği müracaat anındaki seviyede ya da bundan daha iyi idi. %6, 3 (2) hastada görsel sonuçlar çok kötü oldu ve bunlara keratoplasti yapıldı. Sonuç: Bakteriyel keratitli hastalarımızın çoğu uygun tedavi ile iyileşti. Travma en önemli oküler risk faktörü idi. Yaşlı popülasyon keratit açısından artmış risk taşımaktadır.©2008, Fırat Üniversitesi, Tıp Fakültesi
