| Popis: | Purpose: to study the choroidal thickness in children with varied refractions and its dynamics after sclera reinforcement treatment. Material and methods. The study involved two groups: (1) 78 children (average age 12.54 ± 0.35 yrs) with mild hyperopia, low, moderate and high myopia and (2) 40 children with moderate and high myopia who received low invasive (LSP, average age 12.00 ± 0.51 yrs.), or bandaging scleroplasty (BSP, average age 12.33 ± 0.35 yrs) according to Snyder and Thompson and were examined prior to and after the procedure. All patients underwent a standard ophthalmologic examination and had choroid thickness (CT) manually measured by EDI-SD-OCT technique. Results. In group 1, a drop in CТ with refraction growth and axial elongation was found. In group 2, the CT change was traced: in the operated eyes, СТ increased by 34.7 ± 3.15 μm after LSP and by 53.7 ± 1.19 μm after BSP. In fellow eyes, CT showed an increase of 25.4 ± 1.79 μm after LSP and 32.20 ± 0.59 μm after BSP. Conclusions. In the early period after sclera strengthening operations, СТ significantly increases both in the operated and in the fellow eye. Аn increase of CТ probably stimulates collagen biosynthetic activity of the scleral matrix and collagen synthesis, and boosts the inhibitory effect of scleroplasty with regard to myopia progression.
