Outcome of cataract surgery in pediatric uveitis (experience at King Khalid Eye Specialist Hospital).

Abstract

BACKGROUND:Cataract is a major complication of uveitis in children that requires timely management to restore good vision and prevent amblyopia. In surgical management of uveitic pediatric cataracts, published literature has shown a variety of clinical factors affecting the final visual outcome. The aim of this study is to investigate and report the clinical outcomes of cataract surgery and contributing factors impacting such outcomes in children with uveitis.MATERIALS AND METHODS:A retrospective case series of all pediatric patients (<18 years) who were diagnosed with uveitis and had cataract surgery at a tertiary eye institutions, between January 2000 and October 2016. Outcomes measures include best-corrected visual acuity (BCVA) and postoperative complications. Success was defined as BCVA of ≥20/60. Factors related to successful outcome were analyzed.RESULTS:The study sample was comprised of 26 patients (39 eyes). The median postoperative follow-up was 6.4 years. At the last follow-up, only 2 eyes had active uveitis, 3 eyes were controlled without medications, and 34 eyes were controlled with systemic or topical medications. At the last follow-up, 64% of eyes had BCVA ≥20/60. Anterior uveitis and postoperative aphakia were two determinants, in statistically significant manner, found to be positively related to clinical success (P = 0.01 and 0.04, respectively). Etiology of uveitis and use of preoperative intravenous methylprednisolone were not related to the success of obtaining BCVA ≥20/60 (P = 0.5 and 0.99, respectively).CONCLUSIONS:Cataract surgery improves the visual function of children with clinically significant uveitic cataracts. In this study, we found diagnosis of anterior uveitis and postoperative aphakia to be associated with better final postoperative visual outcomes.
