Implications of pars planitis-associated cystoid macular edema on visual outcome and management in children

Purpose Pars planitis is a commonly observed type of pediatric uveitis. The aim of this study was to evaluate the implications of pars planitis–associated cystoid macular edema (CME) on visual outcome and treatment modalities. Methods A retrospective review of medical records in a single center with academic practice. Results Included were 33 children (mean age 8 years, 58 eyes). Eighteen eyes developed CME (31%): in 67% of them, CME was diagnosed at presentation and in 33%, it developed at a mean of 57 months after presentation. Anterior and posterior segment complications were more prevalent in eyes with CME. Papillitis was significantly associated with the development of CME (OR 12.4, 95% CI 2.3 to 65.6, p = 0.003 ). Patients with CME were 1.7 times more likely to be treated with systemic therapy. By the last follow-up, 50% of patients who never developed CME were without systemic therapy compared with 13% of patients who developed CME ( p = 0.034 ). LogMAR visual acuity improvement between presentation and month 36 was 0.41 for eyes with CME compared with 0.14 for eyes that never developed CME ( p = 0.009 ). Conclusion Pars planitis–associated CME entailed higher prevalence of ocular complications, more frequent use of immunomodulatory therapy, and a lower rate of remission.
