249 patients with dislocated lens were observed, and hydrodynamics was studied in 43 eyes with traumatic lens dislocation into the vitreous cavity, in 3 eyes - into the anterior chamber, in 203 eyes - into the vitreous cavity as a result of couching. In 6 cases the lens was removed. The resulting transitional hypertension (74 eyes) was accounted as a reaction to the trauma or surgical procedure and was compensated using traditional dehydration therapy. In the case of sustained hypertension (23 eyes), which were diagnosed as post-traumatic glaucoma, antiglaucoma-tous surgery in combination with conservative treatment was used. Sustained hydrodynamic disturbances were as a rule retentive in character. From the other hand we didn't find convincing proof for hypersecretion. In all cases of hypertension removal of dislocated lenses is nonpathogenetic and often leads to serious complications.
