NCT ID: NCT03431454 Recruiting - Clinical trials for Comparison of Three Vision Therapy Approaches for Convergence Insufficiency

Comparison of Three Vision Therapy Approaches for Convergence Insufficiency

Start date: February 2018
Phase: Phase 2
Study type: Interventional

We compared the effectiveness of three active vision therapy approaches for convergence insufficiency (CI). Patients with eligible criteria and symptomatic CI were included in a prospective study and randomly allocated into three groups. In the home-based vision orthoptic therapy (HBVOT) group, patients were trained to do the pencil push-ups procedure 15 minutes per day, five days a week. In the office-based vision orthoptic therapy (OBVOT) group, 60 minutes of orthoptic therapy using a major amblyoscope twice weekly with additional home orthoptic therapy was prescribed. For the augmented office-based vision orthoptic therapy (AOBVOT) group, orthoptic exercises using three diopter over-minus lenses and a base out prism, in addition to major amblyoscope and additional home reinforcement was prescribed in the same period of time.

NCT ID: NCT03248336 Recruiting - Clinical trials for Convergence Insufficiency

Objective Assessment of Disparity Vergence After Treatment of Symptomatic CI in Children

Start date: September 2, 2018
Phase: N/A
Study type: Interventional

This study is designed to evaluate changes in objective measures of disparity vergence after office-based vergence/accommodative therapy (OBVAT) for convergence insufficiency (CI) in children 12-17 years old.

NCT ID: NCT03059420 Recruiting - Facial Palsy Clinical Trials

Genetic Studies of Strabismus, Congenital Cranial Dysinnervation Disorders (CCDDs), and Their Associated Anomalies

Start date: February 1, 2004
Phase:
Study type: Observational

The purpose of this study is to identify genes associated with impaired development and function of the cranial nerves and brainstem, which may result in misalignment of the eyes (strabismus) and related conditions.
