The purpose of the study was to investigate morphometric peculiarities of the layer of the nervous fibres of the retina and optic nerve in children with amblyopia and hypermetropic refraction by means of the optical coherent tomography. 

Material and methods. There were studied the parameters of the optic nerve, thickness of the layer of the nervous fibres in 149 children (298 eyes) aged 4—12 with amblyopia and hypermetropic refraction by means of the optical coherent tomography, of them there are investigated 84 (56.6 %) children with dysbinocular amblyopia; refraction amblyopia — 37(24.8 %); anisometropic amblyopia — 28 (18.8 %). The control group was made by 10 healthy children aged 6—8. 

Results. There were established great values of size of the optic nerve disc area and thickness of the layer of the nervous fibres of amblyopic eye in comparison with a paired one. Reliably larger sizes of thickness of the layer of the nervous fibres in the lower and nasal sector in the amblyopic eyes in comparison with a paired one are revealed. The results received can be evidence of abnormal postnatal apoptosis in children in refraction and anisometropic amblyopia with hypermetropic refraction.

Key words: amblyopia, hypermetropic refraction, optical coherent tomography, the optic nerve, nervous fiber layer thickness
