Introduction. The study of accommodation ability in children has traditionally been of great interest for many years. In clinical practice, the subjective methods of accommodation research are the most common. Clinical availability of Righton Speedy–i accommodograph provided the opportunity to assess the accommodative function. Purpose. To study the accommodation peculiarities in amblyopic and fellow eyes in children and teenagers with anisohypermetropic amblyopia using computed accommodography. Material and methods. The present study is based on the analysis of the clinical and functional status of 96 patients (192 eyes) with anisohypermetropic amblyopia. Besides the general clinical methods of examination, all patients underwent accommodography. The power of accommodative response (AR), the frequency of accommodative microfluctuations (AMFs) and accommodogram stability were evaluated. Results and discussion. While examining we revealed the significantly higher accommodative response values of the amblyopic eye in comparison with the fellow one, the frequency of AMFs varied within 49-55 mfs/min, corresponding to normal values. The were no any significant differences between groups of amblyopic and fellow eyes. Histograms were not stable and were characterized by the presence of «prolapses», connected with the absence of ciliary muscle contraction in response to accommodative stimulus. Conclusions. AR values of amblyopic and fellow eyes differ significantly. There were no any significant differences between amblyopic and fellow eyes. The presence of «prolapses» is linked with the absence of ciliary muscle contraction and is not an instrument error. The difference between the number of «prolapses» in the histograms of amblyopic and fellow eyes was significant.
