Abstract Details


The purpose of the study was to identify the epidemiological characteristics, predisposing factors and clinical and microbiological profile of infectious keratitis in our hospital.


Tertiary Hospital. Complejo Hospitalario de Navarra.


A retrospective review of corneal scrapes recorded by the microbiology service between January 2014 and December 2017.


A total of 145 corneal scrape specimens were identified. Mean age was 49 years and there was a female predominace (57,2%). Contact lens wear was the main predisposing factor in 62 patients (42,9%). Corneal scrapes grew positive cultures in 37 patients. Gram-positive bacteria accounted for 24 (64,8%), while gram-negative bacteria accounted for 15 (40,5%) with the predominance of Pseudominas aeruginosa Pseudomonas aeruginosa. Topical treatment with more than two antibiotics was prescribed in 93 patients, being tobramycin the most used, 6 patients required surgery. The average time with topical antibiotic was 33 days.


Wearing contact lenses remains the most important risk factor for infectious keratitis.
