title: [Treatment of amblyopia with eccentric fixation of the vertical prism and occlusion--additional experience].
abstract: The authors evaluated a group of 202 patients with esotropia and eccentric fixation. On purpose they selected patients who were treated previously by another pleoptic method without success. The mean age of the patients was relatively high--7.9 years. The mean period of hospitalization was 54 days. Central fixation was achieved in 123 patients, i.e. in 60.8%. Vision became normal only in 40 children, i.e. in 19.8%. According to statistical evaluation by the U-test prisms with a power of 7 and 8 pdpt proved most useful. The method was successful in amblyopia with parafoveolar and paramacular eccentric fixation and acuity of vision of 0.5, 0.3 and 0.1. The treatment did not prove successful in poorer vision and more distant eccentric fixation. The authors do not recommend the use of vertical prisms with a power of 9 and 10 pdpt, as mentioned in their preliminary publication.
