Рurpose. A comparative analysis of clinical and morphological features of retinal detachment (RD) in pediatric and adult practice.Materials and methods. A retrospective analysis of 100 case histories of patients with a confirmed diagnosis of RD in children aged 7 to 18 (mean age 12.6 ± 1.2 years) and adults aged 19 to 80 (mean age 56.8 ± 2.4 years) was performed prior to standard surgery (subtotal vitrectomy with endolaser coagulation and filling of the vitreous cavity with tamponade substances) and 6 months after it. The main parameters for the comparative analysis were gender, age, RD type, cause (risk factor), stage of development of proliferative vitreoretinopathy (PVR), best corrected distance visual acuity, intraocular pressure, presence of postoperative complications, anatomical adherence of the retina after surgery, the fact of reoperation. Statistical analysis was carried out according to two criteria — chi-square and Fisher's test.Results. Statistically significant differences in the type and cause (risk factors) of RD, were found. In children, rhegmatogenous RD was less common than in adults (69 % of cases compared with 80 % of cases), while traction RD was more common in children (29 % of cases compared to 19 % of adult cases). The C stage of PVR development in children were found to be almost twice as common as in adults. Postsurgical outcomes were found to be significantly higher in adults compared with children.Conclusion. RD type, causes and outcomes are statistically different in pediatric and adult practice. Significantly less successful functional and anatomical results of RD surgery in children reflect differences in etiology, pathogenetic features (PVR stage) of the disease, as well as an increased risk of postoperative complications.
