[Regularities and mechanisms of visual perception transformation in presbyopia development].

66 healthy subjects were divided into 2 groups (mean age in the 1st group 18,6+/-0,4 years and 51,7+/-6,5 years in the 2nd group) to study regularities and mechanisms of presbyopia development. Visual pattern characteristics and anatomico-physiological parameters were studied using ultrasound biomicroscopy, electroretinography, ISCEV and visual evoked potentials. The most informative parameters for division of 2 groups are near visual point, fusion capacity in convergence, range of relative accommodation, binocular visual acuity, intraocular pressure, astigmatism, ciliary body thickness, A-wave amplitude on maximal ERG. Presbyopia development is accompanied with significant reorganization of visual analyzer activity, including binocular interaction. Surgical treatment of presbyopia should be supplemented with methods aimed to recover binocular interaction.
