Herpes simplex keratitis: an epidemiologic study

Abstract

Background Recurrent keratitis due to herpes simplex virus (HSV) infection is called herpes simplex keratitis. Aim of the work The aim of the study was to assess the incidence of herpes simplex keratitis to total infectious keratitis, risk factors, and complications of different presentations of herpes simplex keratitis. Patients and methods This prospective and observational clinical study was carried out at the cornea unit of the Tanta University Ophthalmology Hospital on 100 patients who suffered from herpes simplex keratitis during 1 year from the first of January 2021 to the end of December 2021. Results The incidence of HSK was 100, 5.12% cases of total cases of keratitis (1950) who attended the Ophthalmology Outpatient Clinic. The incidence of HSK peaks in middle age from 20- to 60 years, younger patients tend to have more recurrences and complications leading to a greater reduction of vision. Conclusion Recurrences of the disease are the major cause of ocular morbidity. HSV stromal keratitis is found to occur more commonly in recurrences than other types. Earlier diagnosis through increased suspicion in patients with risk factors and rapid diagnostic techniques improve outcomes for HSK patients.
