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. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study is to report two new cases of Usher syndrome associated with Fuchs’ heterochromic uveitis (FHU), to confirm our previous observation of the association between FHU and retinitis pigmentosa (RP), and to evaluate if FHU is particularly associated with Usher syndrome. Methods: Retrospective medical record review of all new RP cases at Hadassah Medical Center between the years 2000 and 2007, review of our previously published data, and a meta-analysis of published relevant articles in peer reviewed journals. Results: During the time frame of the study we diagnosed 58 new cases of RP, of whom one male and one female had the typical findings of FHU, and both had Usher syndrome type II. The difference in the occurrence of FHU between the 616 controls and the patients with RP was significant ( p = 0.0073, Fisher's exact test). In our combined data, FHU occurred only in two types of RP; RP simplex with an incidence of 0.57%, and Usher syndrome with an incidence of 13.5%. This difference between the incidence of FHU in patients with Usher syndrome and other types of RP was significant ( p < 0.0001, Fisher's exact test). Adding up these two cases with what is already published in the literature makes up a total of 17 RP patients with coexisting FHU. Conclusions: This study confirms the association between FHU and RP; and a particularly stronger association with Usher syndrome type II. Although infectious agents seem to play a role, the cause for this significant correlation is still unclear. [ABSTRACT FROM AUTHOR]
