This study aims to detect the effect of sodium chloride 5% solution as an adjuvant treatment with antimicrobial therapy in treatment of bacterial infectious keratits and to assess whether NaCl 5% accelerates epithelial healing, improves microbial eradication, and enhances visual outcomes in bacterial infectious keratitis.

Prospective randomized control study to detect the effect of sodium chloride 5% solution as an adjuvant treatment with antimicrobial therapy in treatment of bacterial infectious keratits and to assess whether NaCl 5% accelerates epithelial healing, improves microbial eradication, and enhances visual outcomes in bacterial infectious keratitis.Data study will include two groups classified as follow : the first group will include treatment of microbial keratitis by antibiotic with sodium chloride 5% , the second group will include treatment by antibiotic only
