The Detection of Occult Retinal Vasculitis on Fluorescein Angiography in Pediatric Uveitis

Abstract

To evaluate the usefulness of fluorescein angiography (FA) to detect occult retinal vasculitis in children with otherwise apparently quiescent intermediate uveitis, posterior uveitis, and panuveitis based on clinical examination alone. Retrospective chart review. Pediatric uveitis patients evaluated at the Children's Medical Center in Dallas, Texas. Retrospective chart review of pediatric patients treated with immunosuppressive therapy in the uveitis clinic at the Children's Medical Center, Dallas, Texas, between September 2015 and September 2016. Patients with noninfectious uveitis requiring immunosuppressive therapy, in which posterior segment involvement (intermediate uveitis, posterior uveitis, or panuveitis) was known or suspected, and whose disease apparently was quiescent on clinical examination were included. The incidence of occult retinal vasculitis detected on FA alone. Fourteen pediatric patients met inclusion criteria. Six patients (43%) demonstrated intermediate uveitis, and 8 patients (57%) demonstrated panuveitis. Eleven patients (79%) were found to show additional evidence of occult retinal vasculitis on FA. Fluorescein angiography can be an important tool in evaluating pediatric uveitis patients with known or suspected posterior involvement for the presence of occult retinal vasculitis. Failure to control occult retinal vasculitis adequately may be a contributing factor to seemingly recalcitrant cases, inability to wean off immunomodulatory therapy, and long-term complications leading to poor prognosis.
