Diagnosis of acute follicular conjunctivitis: A 5-year retrospective analysis in a referral center

Abstract Objective and methods A retrospective analysis was performed using the medical records in a referral center in Mexico over a period of 5 years, in order to determine the frequency of acute follicular conjunctivitis. Results and conclusions A total of 859,986 ophthalmology consultations were given, from which 8,930 were diagnosed with acute follicular conjunctivitis (1.03% of the total). The number of patients diagnosed range between 100 and 200 in the majority of months. In August 2012 an increase was observed with 308 cases, and then decreasing after two months. This study did not demonstrate a highest frequency by month, with exception of year 2012 that showed a peak incidence in the third trimester.
