Abstract

Aim: To evaluate the clinical characteristics of adenoviral keratoconjunctivitis, the management modalities, as well as the incidence of subepithelial corneal infiltrates (SEI).

Methods: Patients with characteristic clinical symptoms and signs, who presented to our clinic within the first week of symptoms and received the diagnosis of adenoviral keratoconjunctivitis between January 2013 and April 2016, were included in the study. A total of 211 patients were included in the study. Patients were evaluated for the incidence of clinical signs, late complications, management preferences, and the effect of diluted povidone-iodine (d-PVP-I) 2%.

Results: Patients' mean age was 33.03±14.76y. We observed an increase in the number of cases according to the years. At presentation and/or early follow-up, the clinical signs were conjunctival hyperemia (100%), conjunctival follicules (79.1%), edema of the eyelids (39.3%), chemosis (16.1%), pseudomembrane formation (16.6%), and corneal epitheliopathy (29.9%). During late follow-up 13.3% patients developed conjunctival subepithelial fibrosis, and 39.8% developed SEI. A significant decrease in the incidence of SEI development was observed in patients who used d-PVP-I 2% (P=0.032; 33.3% vs 45.9%, respectively in patients who received d-PVP-I 2% and who did not).

Conclusion: Adenoviral keratoconjunctivitis has a tremendous effect on patient's comfort and abilities in short-term. Additionally, almost half of the patients develop visual problems related to SEI. According to our clinical experience, using d-PVP-I 2% in the first days of adenoviral keratoconjunctivitis might be helpful in reducing the risk of SEI as a complication.
