[Conservative treatment of vertical recti and oblique muscle deviation in permanent and accommodative strabismus].

The aim of this study was observation of influence of exercises with hypercorrective prisms on the behavior of vertical recti and oblique muscles. The study covered 182 persons with permanent strabismus (4 persons were operated early) and 8 children with accommodative strabismus. As treatment we applied exercises with hypercorrective prisms of 35 dioptres in front of each eye with the edge in direction of the biggest deviation of the eye. A full regression of the hyperfunction of muscles was noticed in 25 patients. The favourable changes were achieved in 38 patients. However the majority of patients were not doing the exercises systematically. Surely it is not the only reason of the lack of final beneficial result of exercises. The applied localization exercises with prismatic hypercorrection in hyperfunctions of vertical recti and oblique muscles gave beneficial result in form of regression of these hyperfunctions or reduction of the range of their deviation. There was also favorable influence on the regression of "residual" deviations of eye after operations. Application of such exercises in accommodative strabismus with hyperfunction of vertical recti and oblique muscles prevent from dissociation of binocular vision and genesis of permanent strabismus.
