Abstract :
Eye is a complex and sensitive organ and is therefore more vulnerable to trauma and various infections ocular infections are one of the most commonly encountered infections. Any part of the eye can be infected by bacteria, fungi, parasites or viruses. In order to minimize the ocular morbidity and mortality, timely antimicrobial treatment must be initiated on the basis of clinical and microbial evaluation. For specific antibacterial treatment, isolation and identification of bacterial pathogens along with antibiotic susceptibility spectrum is essential. Hence, this study was undertaken to isolate and identify the bacterial and fungal pathogens responsible for the development of ocular infections and to determine their in vitro susceptibilities to commonly used antibiotics. A total of 203 samples of suspected ocular infections comprising 117 conjunctival swabs, 34 corneal specimens, 24 lacrimal pus samples and 28 vitreous specimens were analysed. Out of them 102(50.1%) showed growth. 82(40%) were bacterial and 21(10.3%) were fungal isolates. Due to the emergence of drug resistance it is imperative that all ophthalmological samples must be tested for antibiotic resistance as far as possible. Indiscriminate use of over the counter antibiotic eye formulations should be avoided and also it is important to know the changing pattern of pathogens.
