Clinical manifestation, course and treatment results of Coats disease in children

Abstract

Purpose: to analyze the clinical manifestations, course, and results of treatment of Coats disease in children. Materials and methods. We performed a retrospective analysis of medical records of 59 patients with Coats retinitis (83 % were boys) who had been comprehensively examined and treated between 2018 and 2021. After the diagnosis was verified, the children were hospitalized for treatment. Retinal laser coagulation was performed on 61 eyes, angiogenesis inhibitors were administered on 1 eye, and 5 eyes received microsurgical interventions. Results. At the time of disease detection, the children’s age varied from 1 to 16 years. In 97 % of cases, the process was unilateral. An improvement of the anatomical condition and the eye-preserving effect were achieved in 87 %. Visual acuity could only be increased in 19 eyes (31.1 %), all with the initial or the advanced stages of Coats retinitis. Proceeding from our experience, the analysis of polymorphism of clinical manifestations, functional prognosis and differentiated approach to treatment depending on the prevailing clinical symptoms, we suggest a new variant of clinical classification of Coats retinitis. Conclusion. In order to ensure a timely diagnosis of the disease, a very thorough examination of patients in the first decade of life is required. Only an early diagnosis and timely treatment can help achieve not only an eye-preserving effect but also functional results.
