Early juvenile cataract in newly diagnosed type 1 diabetic patients: a description of two cases.

To analyze and summarize the clinical characteristics and treatment of juvenile patients with type 1 diabetes mellitus (T1DM) complicated by early cataract. This retrospective study collected clinical data from 210 children and adolescents newly diagnosed with T1DM who were admitted to the Department of Pediatrics, Tongji Hospital (Wuhan) between 2015 and 2022. Among 210 patients with T1DM, early cataract developed within 3 months before diabetes onset and 12 months thereafter in 2 (0.95 %) patients. The two patients were both females, aged 13 and 9 years, respectively. In both cases, cataracts in both eyes appeared in the early stages of T1DM, showing a short course and rapid development. After intensive insulin treatment for stringent and stable blood glucose control, one patient underwent cataract extraction with significant improvement, and her visual acuity returned to normal. The other patient received intensive insulin therapy and insulin pump therapy for 8 years. Subsequently, she underwent cataract surgery after achieving stable blood glucose levels, without complete recovery of vision. Cataract is a rare complication in the early stages of T1DM in children and adolescents. Ophthalmic surgery is the preferred treatment for patients with diabetic cataract after achieving stable glycemic control, which may help prevent visual impairment. [ABSTRACT FROM AUTHOR]
