Abstract
It is known that the formation of retinoschisis occurs at any age, the senile form is more common, with the same probability in men and women. However, data on the nature of retinoschisis and their prevalence in patients over 18 years of age are fragmentary and unsystematic. Material and methods. A retrospective analysis of the occurrence of retinoschisis in patients older than 18 years was carried out. Results. Retinoschisis was diagnosed in 263 patients (372 eyes), which was 1.1 % of the number of examined patients. Group I included patients with uncomplicated retinoschisis, and group II included patients with complicated retinoschisis. In group I, bilateral changes were observed in 35 % of cases, and unilateral changes were observed in 65 %. In group II, bilateral changes were diagnosed in 44.5 % of cases, unilateral – 55.5 %. The distribution by type of ametropia was equal in both groups: 21.5 % of patients had myopia and emmetropia, in 57 % of cases – hypermetropia. According to the location in both groups, retinoschisis was diagnosed more often in the lower temporal quadrant in 58 % of cases. Conclusion. Retinoschisis is almost 2 times more common in female patients, mainly with hypermetropia and at the age of 50–70 years. In all types of ametropia, retinoschisis was localized in the lower temporal quadrant in 58 % of cases. Keywords: retinoschisis, retinal detachment, retinal hole, laser coagulation
