The aim of the study was to identify the incidence of infective keratitis presenting to the ophthalmology emergency department at Cairo University hospital, the risk factors and the bacterial/fungal spectrum causing the ulcers and to determine the best possible empirical therapy followed by specific therapy after obtaining culture results.

| Measure | Description | Time Frame |
|---|---|---|
| To identify risk factors and the most common causative organisms of microbial keratitis among the Egyptian population through history taking from each patient and the results of corneal sampling taken from the ulcer. | Thorough history taking including risk factors that contributed to the ulcer occurrence. Corneal sampling through corneal scraping from the base and edge of the ulcer that undergoes direct examination and culturing using standard laboratory protocols. | Three weeks for each participant |
| To detect incidence of infective keratitis amongst all ophthalmological casualty cases by documenting the number of cases presenting or referred to the casualty of the ophthalmology department. | Noting down the number of patients diagnosed with microbial keratitis that present to the casualty of a tertiary referral hospital, and calculate the percentage amongst all other ophthalmic casualty cases that present to the emergency as well. | through study completion, an average of eight months |
| To detect antimicrobial susceptibility and resistance of different antimicrobial agents causing corneal infections in our study group. | Antibiotic susceptibility testing was performed by the disc diffusion method (Modified Kirby Bauer technique) using Muller Hinton agar, aerobic incubation at 35°C for 16-18 hours. Anti fungal susceptibility was done using microdilution testing following the CLSI reference method. | two weeks for each participant |
| Measure | Description | Time Frame |
|---|---|---|
| To assess the impact of culture and sensitivity results of corneal scrapings on the initial empirical therapy by calculating the number of cases that needed to shift the initial therapy to another one according to the antimicrobial susceptibility. | Empirical therapy according to the clinical impression that was shifted to another therapy according to the specific sensitivity results of positive growth cases. |
