Abstract
Study Design: Cross–sectional, analytical
Purpose: To identify the prevalence and antibiotic sensitivity of microbial keratitis presenting to a tertiary care hospital in North India.
Methods: 98 subjects of keratitis from the OPD were examined with a standard protocol with KOH, Gram’s stain and culture plating.
Results: KOH wet mount examination revealed 35.5% positive and 53.7% negative. Majority of the Gram’s stain was inconclusive. SDA cultures showed Aspergillus (80%),Fusarium (73.3%) and Candida (8.3%). On BA/CA cultures, S.pneumoniae and S.aureus were the most common Gram-positive isolates with maximum resistance against Levofloxacin. E.coli and P.aeruginosa were the most common Gram-negative isolates with maximum resistance seen for Ofloxacin and Penicillin.
Conclusion: The study highlights an imperative need for regular microbial assessment to modulate the treatment protocol supplementing clinical acumen.
