Clinical features of anterior blepharitis after cataract surgery

Abstract

AbstractWe evaluated the clinical features of postoperative anterior blepharitis following cataract surgery and the efficacy of topical azithromycin retrospectively. Thirty eyes of 30 patients with a clinical diagnosis of anterior blepharitis by 6 months postoperatively among those who underwent cataract surgery at our institution between November 2020 and June 2022 were included. The diagnosis of anterior blepharitis and the assessment of objective and subjective findings were based on the American Academy of Ophthalmology Blepharitis Preferred Practice Pattern®. Azithromycin eye drops were prescribed for all patients, and findings and symptoms before and after the drops were reviewed. The time of onset ranged from 2 weeks to 6 months after cataract surgery, with the most common onset at 2 to 3 months postoperatively (mean time of onset 79.4 ± 39.6 days). The type of anterior blepharitis was staphylococcal blepharitis in 26 eyes and seborrheic blepharitis in 4 eyes, while mixed type with posterior blepharitis was noted in 6 eyes. Symptoms at the time of examination included irritation (including foreign body sensation) in 24 eyes, tearing in 4 eyes, and redness in 3 eyes. The findings and symptoms of anterior blepharitis were alleviated or resolved with azithromycin eye drops in 26 of the 30 eyes, but the blepharitis recurred in 6 of these eyes, requiring azithromycin eye drops to be re-prescribed. The onset of anterior blepharitis after cataract surgery may be related to a gradual decrease in postoperative eye drops. Patients tended to complain of irritation and foreign body sensation, and azithromycin eye drops were effective in such cases.
