| Summary: | The purpose of our study was to analyze the effectiveness of the use of Fresnel prisms for various disorders of the eye movement.Material and methods. The studied group included 40 patients with prismatic correction and was divided into 2 groups of patients depending on the type of strabismus: 25 patients with incomitant strabismus, 15 patients with comitant strabismus. Elastic Fresnel prisms (EFP) were chosen and prescribed for prismatic correction. The patients were under dynamic monitoring under conditions of continuous use of EFP and positional trainings were performed if necessary (when doubling wasn’t completely compensated by EFP). The study had a prospective character.Results and its discussion. The prismatic correction made it possible to eliminate diplopia in direct gaze position and peripheral gaze directions in all 25 patients with paretic strabismus. In 18 out of 20 cases, the prismatic correction allowed to achieve functional recovery without subsequent chemorecession or surgical treatment. In 8 patients with comitant strabismus after the first stage of surgical treatment with stable deviation, binocular vision was formed under natural conditions. In 1 year, dynamic prismatic correction contributed to the recovery of 7 patients without surgical treatment with orthophoria in vivo.Conclusion. Prismatic correction of diplopia as an independent or additional functional method of treatment contributes to the achievement of the comitance of the eye muscles. |
