Abstract
ABSTRACT Purpose To retrospectively analyze long-term outcomes of pediatric pars planitis (PP). Methods PP was defined as vitreal inflammation with snowbank or snowball formation in the absence of a related disease. Eighty-five eyes of 44 patients were included in this study. Demographic and clinical characteristics were obtained from medical records. Results Approximately 70% of the patients were males; the mean patient age was 10.4 ± 3.6 years at presentation, and the mean follow-up time was 42.8 ± 27.9 months. At presentation, the mean best corrected visual acuity (BCVA, logMAR) was 0.17 ± 0.27 in the right eyes and 0.27 ± 0.33 in the left eyes. Common symptoms included blurry vision (29 eyes, 65%), redness (17, 38%), pain (8, 18%), and floaters (5, 11%). Sight-threatening complications included optic disc edema/hyperemia (26, 30%), cataracts (16, 18%), macular edema (16, 18%), and glaucoma (15, 17%). All 38 patients who initially required systemic treatment received corticosteroids. During the follow-up, 24 patients were treated with azathioprine, 20 with methotrexate, 11 with cyclosporine, 20 with adalimumab, and 8 with infliximab. At the final examination, the mean BCVA of the right and left eyes improved significantly (0.08 ± 0.23 and 0.06 ± 0.17, p = 0.006 and p < 0.001, respectively). The severities of vitritis, anterior chamber inflammation, snowbank/snowball formation, and endotheliitis decreased (all p < 0.001). Thirty-one patients remained on systemic treatment, with only four patients still receiving corticosteroids. No life-threatening adverse effects were reported. Conclusion Despite pediatric PP’s mild course, severe vision-threatening complications can occur. Immunomodulatory or biologic agents are important for controlling inflammation and tapering corticosteroids. Further research could enhance understanding of optimal treatments.
