Purpose to study the peculiarities of central retina morphometric parameters in amblyopic and pair eye in children with amblyopia.

Material and methods 137 children (274 eyes) of 4—12 y. o. with an amblyopia and hypometropic refraction were examined, among them with the disbinocular amblyopia — 80 (56,6 %), with refractive amblyopia — 33 (24,8%) and with an isometropic amblyopia — 24 patients (18,8 %). Control group was 20 healthy children 6—8 y.o. The comparative description of retinal macular area morphometric parameters (macular volume, fovea thickness, thickness of retina in 1 MM, 3 MM and in 6 MM from the center of fovea in four sectors in amblyopic and pair eyes) was conducted applying standard protocols with the help of Stratus OCT model 3000. Results the greater volume of macula, thickness of fovea, are revealed, increased thickness of macular retina area in 1 mm and in 6 mm from the center of fovea mainly in a lower sector in amblyopic eyes as compared to a pair. Generally thickness of macular retina in segments was thicker in 3 mm in comparison to 6mm from a center in amblyopic as well as in the pair eye.

Conclusions The differences in morphometric parameters in central area of retina are established between amblyopic and pair eye that is confirmed by the greater thickness of fovea, of macula in 1 mm and in 6 mm from center in all segments. The large thickness of retina is set for certain in fovea and macula by scans (nasal, temporal, superior) on the amblyopic eye in comparison to pair eye. Generally thickness of macular retina in segments was thicker in 3 mm in comparison to 6mm from a center in amblyopic as well as in the pair eye.

Key words: amblyopia, optical coherent tomographyfl, morphometric parameters of central retina in amblyopic and pair eye.
