Abstract Details


Bacterial keratitis caused by various microorganisms is one of the most common pathologies of the cornea around the world. Treatment of purulent corneal ulcers remains one of the urgent problems of ophthalmology, which is due to the high frequency of this pathology and the special severity of the disease, leading to a significant decrease in vision, and often to the death of the eye.


Research was conducted in the Bacteriological Laboratory of International Center Eye Diseases of Turkmenistan, studying the nature of microflora and the predisposing factors for the development of bacterial keratitis.


252 eyes, 162 (64.3%) men, and 90 (35.7%) women were examined from January 2003 to December 2009. Age varied from 12 to 80 years. A retrospective review of eyes with purulent bacterial keratitis was performed on 252 eyes. During the period of January 2003 to December 2009 various types of keratoplastic surgeries were carried out. All eyes underwent standard ophthalmological examinations. Corneal scrapings were collected and transported and microbiologically processed using standard operating procedures.


In a bacteriological study we found that n the group of Gram-negative bacilli of 120 eyes (47.6%), the prevailing pathogen was Pseudomonas aeruginosa of 85 eyes (33.7%) and Pseudomonas spp. was found in 20 eyes (7.9%). While in the group of Gram-positive cocci were detected in 76 eyes (30.2%) among which dominant Staphylococcus epidermidis 29 eyes (11.5%), (predominant) in 28 eyes (11.1%) identified Staphylococcus aureus. In 56 eyes, the flora was not detected. Fungal flora and acanthamoeba were not found.


Bacterial keratitis is a serious disease with progressive course, ulceration and perforation with a risk of endophthalmitis. According to our data, bacterial keratitis is more common in men (64.3%), living in rural areas (66.7%). Corneal injury (62.3%) was the dominant risk factor. A bacteriological study showed that the Gram-negative flora is dominant, namely Pseudomonas aeruginosa 33.7%.
