TL;DR: One hundred and two patients with anisohypermetropic amblyopia without strabismus were studied and patching was used on the nonamblyopic eye as discussed by the authors.
Abstract: One hundred and two patients with anisohypermetropic amblyopia without strabismus were studied. Microstrabismus was excluded by detailed orthoptic examinations including visuscopy and Cuppers' bifoveal correspondence test. Treatment consisted in wearing correcting glasses and part-time or full-time patching of the nonamblyopic eye. In patients with dense amblyopia patching of the amblyopic eye was done and Cuppers' after-image method of pleoptic therapy was instituted as the initial procedure. When visual acuity improved sufficiently by this therapy, patching was used on the nonamblyopic eye. Sixty-five (63.7%) patients showed 2 lines or more improvement on the Snellen chart. Though young children (6 to 12 years) improved their visual acuity more often than those aged 13 to 20 years, a considerable number of patients (50.0%) in the older age group improved their visual acuity after therapy. The improvement in visual acuity was accompanied by improved stereoacuity in 49.0% of the patients. It is therefore suggested that every effort should be made to treat these patients even after the age of 12 years.

TL;DR: Stereoscopic acuities as determined on the stereoplotter and the Howard‐Dolman apparatus were improved at better than a 0.05 significance level as computed on the Wilcoxon signed rank test and Student's t‐test for the difference between two dependent means.
Abstract: Ten stereophotogrammetry students and three graduate photogrammetrists were given 7 weeks of nonspecific orthoptic exercises. The visual systems of these 13 experimental subjects were matched to those of 13 control subjects chosen from the students and staff of the Ferris State College of Optometry. Stereoscopic acuities were determined before and after the training period on both groups using a Wild Stereoplotter, a Howard-Dolman apparatus, and the Keystone Multi-Stereo Test. Stereoscopic acuities as determined on the stereoplotter and the Howard-Dolman apparatus were improved at better than a 0.05 significance level as computed on the Wilcoxon signed rank test and Student's t-test for the difference between two dependent means.

TL;DR: Strabismus is an infrequent problem following intraocular and orbital surgery, however, when these patients present with persistent diplopia further management is necessary.

TL;DR: All primary school children beginning their 1st school year in Bergen in the autumn of 1977 have been incorporated in a specialized visual and orthoptic examination program, and 106 children were found to be in need of Orthoptic/ophthalmological treatment.
Abstract: Parallel to the comprehensive interscandinavian project on DYSLEXIA (the so-called BERGEN PROJECT), all primary school children beginning their 1st school year in Bergen in the autumn of 1977 (N= 3442) have been incorporated in a specialized visual and orthoptic examination program. All the children have had a screening examination which has given informations concerning: Visual acuity, stereoscopic vision, strabismus (manifest/latent, type and degree), fusion, convergence, bifoveal fixation and dominant eye and preferred hand. 106 children were found to be in need of orthoptic/ophthalmological treatment. 12 of those have dyslectic problems, whilst in another 221 dyslectic children the orthoptic examination was concluded “NORMAL”. Dyslectic children which have not profitted well on the educational training programs will be re-assessed by the orthoptist/opthalmologist in consultation with the teachers and pschycologist. They will then be treated for small “pschycological” latent deviations, minimal refractiv and binocular errors and for crossed reference eye. Progress of readincr ability for these orthoptically treated children will be evaluated.

TL;DR: In a survey of 461 curves from patients with asthenopia and oculomotor imbalance the presumed relation between orthoptic data and type of curve was confirmed.
Abstract: Prism fixation disparity curves have been classified into five types: sigmoid with flat centre, sigmoid, flat, above abscissa, below abscissa. On casuistical and theoretical grounds these curves were considered characteristic for five clinical situations: Normality, convergence defect, fusion defect, esophoria, exophoria, respectively. In a survey of 461 curves from patients with asthenopia and oculomotor imbalance the presumed relation between orthoptic data and type of curve was confirmed.
TL;DR: A test score combining the results of binocular and uniocular measurements was developed that allowed correct correct classification of 70% (31) of patients studied.
Abstract: • Forty-four patients with diplopia caused by myasthenia gravis, ocular myopathies, and ocular motor nerve palsies underwent complete orthoptic evaluations before and after intramuscular injection of neostigmine (Prostigmin) methylsulfate. A test score combining the results of binocular and uniocular measurements was developed that allowed correct classification of 70% (31) of patients studied.
TL;DR: Advantages of oculomotor biofeedback therapy are shorter treatment time, elimination of lengthy home training exercises, and enhanced patient motivation.
Abstract: Twelve exotropes of various types received oculomotor biofeedback therapy at State College of New York (SUNY) University Optometric Center. Feedback of a variable pitch tone which reflected changes in ocular vergence reinforced motor control of eye posture. Patients were trained to achieve and sustain alignment in a variety of viewing situations. The six intermittent exotropes in the study who did not have amblyopia or prior history of unsuccessful surgical or orthoptic therapy achieved the highest recovery rating after training. The amblyope and those who had orthoptic training learned to voluntarily correct their eye position, although they did not achieve as acute a sensitivity to loss of alignment as did the others. Therapy restored eye control at near in a young constant exotrope whose condition resulted from severe neurological dysfunction. A constant postsurgical exotrope who had no ability for sensory fusion made little progress. Advantages of oculomotor biofeedback therapy are shorter treatment time, elimination of lengthy home training exercises, and enhanced patient motivation.
