Clinical Characteristics and Therapeutic Outcomes of Pediatric Blepharokeratoconjunctivitis.

Abstract

The purpose of this study was to determine the clinical characteristics, disease course, therapeutic outcomes, and prognostic factors for pediatric patients with blepharokeratoconjunctivitis (BKC). A retrospective medical chart review was performed for patients aged 15 years or younger who had been diagnosed with BKC between 2004 and 2020 at 2 tertiary hospitals in Korea. The following data were collected: demographics, medical history, ocular findings, geometric profiling of corneal lesion, medical management, and outcomes. A total of 137 patients (90 female and 47 male) were included. The patients' mean age was 8.3 ± 3.8 years at disease onset. Both eyes were involved in 57.7% of cases. The most common corneal lesion was corneal neovascularization (77.4%), followed by clinically visible corneal infiltration (51.8%) and stromal scarring (43.1%). Most of the corneal lesions involved a single quadrant, most commonly the inferior quadrant. After treatment, disease remission was achieved in 95% of patients, and visual acuities improved from 0.2 ± 0.3 logarithm of minimal angle of resolution at disease presentation to 0.1 ± 0.3 logarithm of minimal angle of resolution at final follow-up ( P = 0.001). Recurrence occurred in 52.6% of patients. Cylinder power was significantly higher in patients with recurrence than in those without. The number of cases of recurrence was positively associated with final cylinder power. Although the treatment induced disease remission in 95% of children with BKC, recurrence occurred in 52.6% of those cases. Because recurrence resulted in significant astigmatism, careful observation for recurrence and prompt management are warranted for preservation of vision in pediatric patients with BKC.
