Kukharenko D. The Computer system of the before operation planning of surgical correction of pathology of oculomotor vehicle of human

The object of study is the setting for human eyeball in the initial position under the action of the entire complex of muscles. The study examined a computer system preoperative planning of surgical correction of oculomotor pathology staff person. Research Methods - The research is based on the provisions and methods of system analysis, the theory of neural networks, methods of geometric affine transformations, Mathematical modeling and methods of discriminant analysis and statistical data. The aim is to develop a computer system preoperative planning of surgical correction of the oculomotor system. To achieve this goal in the following tasks: analyze existing models of human oculomotor apparatus and methods of their construction; develop methods to determine the coordinates of anatomical structures on the surface of the model of the eyeball; develop methods to calculate the moments of forces the eye muscles to the surface of the model of the eyeball; develop a mathematical model for the implementation of the proposed methods; develop algorithms and software for the implementation of mathematical models. The practical significance of the work. These research results are of practical importance, as evidenced by patents and acts implementing the results. The developed computer system allows to predict the result of the operation on the eye muscles, which can be used in hospitals to improve surgery for strabismus. The basic medical and technical requirements and practical guidance for the design. Three-dimensional computer model of the oculomotor apparatus makes it possible to imagine the causes and mechanisms of certain forms of strabismus, can be used as a visual aid for the students and can be used in medical practice without additional extensive training medical personnel. The results obtained are used during surgery in Kremenchug City Children's Hospital, the performance of the state budget and the subject in the classroom KNURE. Scientific novelty: the first time a method for determining the coordinates of the surface model of the eyeball, which by definition of the geometric properties of the eyeball allows the computer planning surgery; first developed a method for calculating the moments of forces on the surface of the eye muscles of the eyeball model that is based on determining the resultant torque of the whole complex of eye muscles and to determine the deviation of the eyeball from the original position. A method for creating three-dimensional model of the oculomotor system, which is due to the introduction of the geometric properties of the eyeball in ophthalmic spherical coordinate system takes into account the individual anatomical variability in computer planning surgery. Proposed to use in the preoperative surgical planning computer system that improves the efficiency of surgery by 27%. Computer system significantly reduces the time being of the patient under general anesthesia due to the speed and convenience of obtaining the necessary calculations. A new computer system for preoperative planning of surgical correction of strabismus makes it possible to imagine the causes and mechanisms of certain forms of strabismus and predict the results of surgery on the eye muscles. By using this computer system, ophthalmologist surgeon will choose the optimal surgical treatment and dosage of interventions to individual patients.
