Rotating grating treatment of amblyopia with and without eccentric fixation.

Treatment of amblyopia with and without eccentric fixation using short term occlusion and rotating gratings was analyzed in a controlled study. A control group (n = 18) viewed a blank rotating disc for 15 minutes once a week for ten weeks while the treatment group (n = 20) observed rotating gratings for the same time period. Both groups performed visually guided tasks to maintain treatment interest. Visual acuity was analyzed before and after each treatment session using a multiple Landolt ring chart. Data were gathered in a double masked manner. Analysis did not reveal a statistically significant improvement of visual acuity with rotating grating therapy for treating amblyopia with or without eccentric fixation.

Clinical aspects of cyclophoria: definition, diagnosis, therapy.

Cyclodeviations are rotations of the eye about an anterioposterior axis. Cyclorotations are either manifest deviations (cyclotropia) or latent (cyclophoria). Perhaps 5% of patients have symptoms related to uncompensated cyclophoria. Diagnostic techniques include fixation disparity evaluation combined with binocular refraction at distance and near. Biofeedback with afterimages, cyclovergence training, surgery, and multiple eyewear are some possible treatment methods.

Relationship between fixation disparity curves and symptoms in monofixators.

Patients with small angle strabismus usually are asymptomatic. Occasionally, however, binocular asthenopic symptoms are reported. Two monofixators, one symptomatic and the other asymptomatic, with similar profiles on strabismic evaluation had forced vergence Fixation Disparity Curves (FDC) measured. Slope of the FDC may help to discriminate between the symptomatic and asymptomatic patient.

Prevention and care of strabismus in infants and pre-school children.

Care of children at risk of developing strabismus is discussed. Recommended care consists of parental counseling combined with early and periodic examinations. Examinations should begin by age 3 weeks and continue at 3-6 month intervals until the child reaches age 5. Treatment of strabismus or amblyopia should begin as soon as these conditions exist. Using recent electrophysiological research as a background, a model care for infants with congenital strabismus is presented. Care reports are presented describing results of orthoptic treatment of non-congenital strabismus.

Vision training for presbyopic nonstrabismic patients.

Home vision training was prescribed for 161 presbyopic patients (ages 45 to 89) who had vision-related symptoms and convergence insufficiency or visual skills deficiencies. Most patients required 10 weeks or less of treatment, the longest treatment period being 15 weeks. Elimination of the symptoms and improved responses on certain optometric tests was achieved by 92% of the patients. Evaluation 3 months after therapy indicated that 77 patients required additional training, the older patients requiring it more often, to retain the initial improvement.

Binocular vision therapy for general practice.

Guidelines are given for selection of patients who need binocular visual therapy. These guidelines are useful for the optometrist who wishes to start binocular vision training in his practice. Treatment techniques for each type of binocular problem are discussed. Case reports are included which detail diagnosis and treatment.

A vision profile of American Indian children.

In an unselected study, Modified Clinical Technique screening plus keratometry was done on 398 American Indian grade school children. The results are compared to screening results for Caucasin grade school children.

A home pleoptic method.

A method of initiating an after-image in an amblyopic eye with eccentric fixation by using Haidinger's brush for fixation control is described. This technique makes home pleoptics possible.

Comparison of vision screening by lay and professional personnel.

A previously described vision screening procedure was administered to 652 elementary school children, using lay volunteers. These students were later screened by optometrists, using the Modified Clinical Technique (MCT). Using MCT as the standard, the lay screening correctly identified 90% of the children; the incorrect identifications included 28 children (4.3%) as false negatives and 36 children (5.5%) as false positives. Analysis indicates a lower cost for the combined lay and professional screening than for professional screening alone.
