Epidemiology of Pediatric Uveitis

Uveitis Profile in Children and Its Impact on Vision at Queen Rania Children's Hospital

AIM

The aim of this study was to explore the patterns of pediatric uveitis and the types of ocular complications of uveitis and to determine the possible risk factors associated with visual impairment.

METHOD

This was a cross-sectional study conducted at Queen Rania Children's Hospital between June 2020 and June 2023. All children diagnosed with uveitis were enrolled in the study. After collecting data from the patients and reviewing their medical records regarding age, gender, and past ocular and medical history, the patients were subjected to a detailed ophthalmic exam including best-corrected visual acuity (BCVA). Anterior segment exam using the slit lamp, intraocular pressure exam using Goldmann applanation tonometry, and posterior segment exam using 78 and 90 diopter Volk lenses were performed. Patients with other ocular diseases that affected visions not related to uveitis were excluded from the study.

RESULTS

A total of 82 children, accounting for 130 eyes, were enrolled in this study, with ages ranging from 2 to 16 years (mean age 10.5±4.3 years). Among them, 27 were males, constituting 32.9% of the participants. Unilateral uveitis was observed in 34 eyes, representing 26.2% of cases. The mean age of uveitis onset was 6.9±1.9 years, and the mean disease duration was 4.8±0.4 years. The majority of cases i.e. 90.8% (n = 74) were non-infectious, with 92.3% (n = 76) classified as non-granulomatous and 79.2% (n = 65) categorized as chronic. Anterior uveitis was the most prevalent site of inflammation in 70.8% of cases (n = 58), followed by panuveitis in 20.0% of cases (n = 16), intermediate uveitis in 6.2% of cases (n = 5), and posterior uveitis in 3.0% of cases (n = 2). The cause of uveitis could not be identified in 40.0% (n = 33) of cases. Juvenile idiopathic uveitis emerged as the most commonly known disorder associated with uveitis in 40.0% (n = 33) of cases. Complications were identified in 52.3% (n = 43) of cases, with posterior synechiae being the most prevalent; 26.9% (n = 22) demonstrated an improvement in BCVA, while 21.5% (n = 18) experienced a decline in BCVA relative to the initial assessment Conclusion: Pediatric uveitis tends to manifest as anterior, chronic, bilateral, and non-granulomatous. Higher frequencies of severe visual impairment are linked to panuveitis, infectious and granulomatous uveitis, early-onset, long-duration cases, and male gender. The use of biologics has a positive effect, significantly improving or preserving visual acuity.
