Insights
Pediatric uveitis, though rare, can lead to vision loss. This study found most childhood uveitis cases remain undiagnosed, with toxoplasmosis and toxocarosis as common infectious causes.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Immunology
Context:
- Pediatric uveitis is a significant cause of vision impairment in children.
- Understanding the epidemiological patterns and etiological factors is crucial for timely diagnosis and management.
- This study analyzes a cohort of pediatric uveitis cases to elucidate disease characteristics.
Purpose:
- To analyze the epidemiological patterns and etiological factors of pediatric uveitis.
- To identify common causes, ocular complications, and visual outcomes in children with uveitis.
Summary:
- A retrospective analysis of 49 children with uveitis revealed a mean age of onset of 11.6 years.
- Idiopathic uveitis was most common (57.2%), followed by infectious causes like toxoplasmosis and toxocarosis (14.1%).
- Ocular complications, particularly cataract (24.5%) and cystoid macular edema (20.5%), affected 65.3% of eyes, with 18% experiencing vision loss (<20/200).
Impact:
- Highlights the high rate of undiagnosed uveitis in children, emphasizing the need for improved diagnostic approaches.
- Identifies key infectious agents and systemic associations, guiding targeted etiological investigations.
- Underscores the significant risk of visual impairment and the necessity of rigorous ophthalmological follow-up for better prognoses.
Purpose:
To analyze the patterns of pediatric uveitis.
Patients And Methods:
A retrospective study of 49 children with uveitis, examined from January 2000 to December 2009. All patients underwent a complete ophthalmic examination and an etiological search; follow-up varied from six months to seven years.
Results:
The mean age at onset of uveitis was 11.6 years (range, 5-14 years). The sex ratio was 1.04. Uveitis was bilateral in 59.20% of the patients, anterior in 22 cases (44.9%), intermediate in seven cases (14.3%), posterior in four cases (8.1%), and panuveitis was found in 16 cases (32.7%). In 57.2% of the patients, uveitis was idiopathic. Infectious uveitis was responsible for 14.1% of the cases, the most common of which were toxoplasmosis and toxocarosis. Systemic associations were found in 22.5%, with juvenile idiopathic arthritis in 6.2%. A specific ocular entity was responsible for 6.2% of the cases. Ocular complications occurred in 65.3% of the affected eyes, the most common being cataract (24.5%) and cystoid macular edema (20.5%). The final visual acuity was less than 20/200 in 18%.
Conclusions:
Pediatric uveitis is rare but may cause visual loss. In our study, the cause of uveitis in childhood remains most often undiagnosed. Toxoplasmosis and toxocarosis are the most frequent infectious causes. Cataract was the most frequent complication. A strict ophthalmological follow-up is mandatory to improve the prognosis.
