Abstract:
For one year survey to study predisposing factors of microbial keratitis, a total of 632 patients were attending Ophthalmology Department, Tanta University Hospital, where 7 patients had infection in both eyes so total infected eyes were 639. There were 10 cases with mixed infection, so the total isolates obtained from 639 infected eyes were 649 isolates (362 bacterial isolates = 55.8% out of total isolates and 287 fungal or yeast isolates = 44.2% out of total isolates). The most common predisposing factors for infectious keratitis were ocular trauma. Although vegetative trauma was the most common risk factor for microbial keratitis, contact lens wearing, use of steroids, dry eyes, were important risk factors for keratitis. VITEK® systems were used for more accurate identification of microbial keratitis causative agents and decreasing the turnaround time. The Mean time of identification turnaround time was for filamentous fungi (25 minutes), bacteria (4:51 hours) and yeast (17:59 hours). It was observed that the predominant bacterial isolate was Staphylococcus aureus (131 isolates 20% of total isolates) followed by Pseudomonas aeruginosa (81 isolates 12% of total isolates). The predominant yeast isolate was Candida albicans (58 isolates/ 9% of total isolates). The predominant filamentous fungal isolate was Aspergillus flavus (44 isolates/ 7% of total isolates).
