[Non-surgical treatment of convergent strabismus with a localization method].

The results of non-operative treatment of 100 cases of convergent strabismus, 75 with macular and 25 with eccentric fixation are presented. Two kinds of prismatic correction were applied: hyper-correction with alternative obturation and correction, exactly compensating the squint angle. The aim of the former one was to decrease the squint angle and help the eyes to be in prismatic orthotropy. The latter prisms enabled permanent symmetrical stimulation of the retina which lead to the development of normal binocular vision. The duration of the treatment was 3-10 years. In all patients, parallel position of the eyes, normal binocular vision and improvement of visual acuity were achieved.
