Resolution of cyclic esotropia with 5-year follow-up after brief Fresnel prism treatment.

Cyclic esotropia is a rare form of strabismus that is characterized by a recurring esotropic deviation, usually with a 48-hour cycle. On esotropic days, the patient has a constant deviation with suppression, followed by a day with straight eyes and good binocular function. We report a case of cyclic esotropia in which the cycling resolved with 2 months of Fresnel prism for the amount of the distance deviation on her "straight" days.

Aniseikonia: A 21st Century Look.

: Aniseikonia, an appreciation of image size differences between the eyes, can produce symptoms in patients, ranging from headaches to loss of fusion. The purpose of this research was to take a 21st century look at aniseikonia. : Kellogg Eye Center patient records were evaluated for measurable aniseikonia in patients tested with the Aniseikonia Helper, a tablet-based application.

Testability Study of the Titmus V3 Test in Pre-school Children.

Significance: Vision screening can identify people who have vision problems requiring a comprehensive examination. When children are screened, the most prevalent serious problem is amblyopia secondary to uncorrected ametropia. Screening also identifies strabismus, which can lead to loss of binocularity.

Fresnel prism use among orthoptists.

Purpose: To better understand current uses of Fresnel prisms.

Methods: A seventeen-question survey was completed by members of the American Association of Certified Orthoptists (AACO).

Results: Surveys were emailed to 211 orthoptists with a 36% response rate (n = 76).

Management of binocular diplopia due to maculopathy with combined bangerter filter and fresnel prism.

Purpose: To describe treatment of binocular diplopia due to maculopathy with a combination of Bangerter foil and Fresnel prism. Methods and Case Report: A protocol for prescribing a combination of Bangerter foil and Fresnel prism is described. A series of three patients in whom a Bangerter foil or prism alone were ineffective for binocular diplopia due to maculopathy, along with a detailed case report of one of these patients, illustrates how a combination of both were used to treat the diplopia.

Current concepts in the management of concomitant exodeviations.

Intermittent exotropia is the most common form of divergent strabismus. Treatment is indicated with increasing tropia phase to preserve or restore binocular function and restore/reconstruct normal ocular alignment. While medical treatment is sometimes helpful for temporary relief, surgical therapy is the preferred definitive treatment modality by most pediatric ophthalmologists and strabismologists.
