Морфометрические особенности теноновой капсулы при различных видах клинической рефракции

The work studied morphometric features of Tenon's capsule on 47 samples from 35 children with various types of clinical refraction (in cases of hyperopia and emmetropia in conjunction with strabismus 24 and 2 samples were studied respectively; with mild myopia-1, average myopia-6 samples and high myopia -14). Material was collected during surgery on muscles in strabismus and scleral reinforcement in progressive myopia. Tenon's capsule samples were examined by transmission electron microscopy. The results showed that with refraction enhancement the following parameters increased: Tenon's capsule cell density of the 1st and 2nd sections for myopia accounting for, 1,56 ± 0,112 and 1,587 ± 0,117 respectively, and hyperopia 1,098 ± 0,127 and 1,023 ± 0,121 (r≤0,005); the maximum length of fibroblasts was 25,95 ± 1,45 at myopia and hyperopia 20,72 ± 1,64, (r≤0,005); ratio of mast cells in the first and second sections was 0,079 ± 0,015 and 0,072 ± 0,015 at myopia and 0,045 ± 0,025 and 0,008 ± 0,004 at hyperopia respectively (r≤0,005). The study revealed the differences in morphometric structure of Tenon's capsule in different types of clinical refraction, the active participation of fibroblasts in the remodeling of Tenon's capsule, the increase in the number of mast cells with a high index of granular saturation myopia.
