Romanenko D. Diagnostics optimization of concomitant strabismus with combined method of automated analysis of eye globe movements

Object: concomitant strabismus. Purpose: optimization of concomitant strabismus diagnostics by development of a combined method, which includes automated analysis of two-dimensional eye globe pictures (AATEP) and optimal volume of surgical treatment determination in three-dimensional biomechanical eye model (TBEM). Methods: visometry, refractometry, strabometry, determination of ocular motility and oblique muscle function, Worth four-dot test, modelling of surgical treatment volume in TBEM, statistical methods. Auto refractometer, ocular coordimeter, Worth four-dot test. Data about eye globe motility of healthy subjects was added: there was measured volume of binocular eye globe motility in middle gaze deviations using kinetic method. Size of deviation angle in concomitant strabismus was specified owing to registration of hidden "muscle" component of deviation. Data on oblique muscle dysfunction in concomitant strabismus was specified owing to simultaneous registration of vertical and horizontal eye globe displacement in adduction position. With AATEP investigation time of strabismus patient is reduced by 25 min compared to conventional methods. 21,5% higher surgery success rate was achieved in strabismus patients whose surgery volume was planned in TBEM based on diagnostics with AATEP method. The results were implemented in the Filatov Institute of Eye Diseases and Tissue Therapy of NAMS of Ukraine, Dnipropetrovsk Regional Clinical Eye Hospital, Eye Microsurgery Center of the Herbachevskyi Zhitomir Regional Clinical Hospital. Sphere of use - medicine, ophthalmology.
