Binocular training with full prismatic correction after the monocular therapy by occlusion brings a further improvement of the visual acuity as well as shown in a study of 29% (138 cases) of 469 selected cases with binocular problems and 43% (260 cases) of about 600 unselected cases of squint actually in treatment in the practice and orthoptic years the strength of the prisms is determined with the monocular covertest, in elder patients with the Polatest. If the amblyopia is connected with squint, an operation will only be performed after the amblyopia is improved and some degree of binocularity is reached by means of prisms. - 80% of the selected and 48% of the unselected cases reached a visual acuity of 1,0 on the amblyopic eye, including originally severe cases with eccentric fixation. In about 80% of all cases binocular single vision and stereopsis were reached. Failures were mainly due to remaining eccentric fixation, mostly connected with severe ARC, too advanced age at ting the prisms, too long intervals between controls etc.) - Finally, the importance of cooperation with an orthoptist and the social medical aspects of better chances for amblyopics are accentuated.

Twenty patients with concomitant strabismus, ARC and a horizontal deviation of between 10 and 30 degrees (13 convergent, seven divergent) were examined with striated glasses to determine areas of anomalous simultaneous binocular vision. Such an area was found in a zone between the visual field centers of the two eyes in 18 cases. On the basis of these findings the authors suspect that harmonious ARC permits anomalous binocular vision only in field areas where retinal points with identical images have no significant difference in function. In the other areas of the binocular visual field, ARC provides for optimal perception of detail by suppression of the more peripherally situated retinal point.

Intermittent divergent strabismus represents an entity in terms of motoric characteristics rather than in its sensorial basis. Separate investigations were carried out in two clinics on 156 patients. The results were evaluated together, the authors discussing each case. Only in 27 cases was the condition cured. The main group comprised 78 patients with subnormal binocular vision based on facultative microexotropia and instable/normal correspondence. Basic microexotropia with obligate ARC was found in 51 cases, i.e., more often than expected. Testing the stereo threshold proved to an inadequate criterion for cure.

Our 10-year retrospective study includes 178 children below the age of 10 years, operated for alternating convergent squint. Inclusion criteria were: Absence of amblyopia and an angle of squint less than 45 pdpt so that alignment of the eyes in only one operation could be expected. One hundred children received preoperatively a prismatic correction of the distance deviation for a period of 6-15 months; 78 cases were treated with glasses and occlusion. In the prism-treated group a significantly better alignment (p = 0.0001) with a motorial gain of 7-8 pdpt was observed 6 months after surgery; also better sensorial results with significantly (p = 0.0001) more cases of stable NRC or harmonious ARC and improved binocularity were achieved. Unlike the type of esotropia, the preexisting retinal correspondence significantly influenced the motorial outcome (p < 0.05). Fewer reoperations were necessary in the prism-treated group (p = 0.001). Our results indicate that a prolonged prismatic correction is an effective preoperative treatment in patients with alternating convergent squint.

Taking into consideration the age of the patient, the strabismus surgery targets different things. Thus, for infants, the goal of the surgical intervention for congenital esotropia, is to prevent the occurrence of amblyopia and binocular vision dysfunctions (ARC, suppression). In preschool children, we operate aiming the recovery of the binocular vision, while in children over ten years old, the surgery is done only for esthetic reasons. On the other hand, in adults, the strabismus surgery has two aspects: for esthetic reasons in monocular strabismus with amblyopia, or for diplopia treatment in strabismus of traumatic or neurological cause. To get the best results, the surgical intervention has to respect several rules, which differ with patient's age. This presentation will discuss several surgical procedures: for congenital esotropia (including its advantages and drawbacks), for preschool children strabismus and also for strabismus in adults. We will also review the surgical treatment for Duane syndrome, Ciancia syndrome and superior oblique muscle palsy.
