Effects of Stulln and Accommodative Training

• Status: Withdrawn

• Target enrollment: 0
• Participant gender: All

Summary

The present study tests the hypothesis that Stulln eyedrops improve accommodative functions by improving the short term facility of ciliary muscles that can be transferred into long-term adaptation. To test this, the investigators propose to conduct a prospective randomized control trials where participants with accommodative dysfunctions are randomly assigned to four groups: control, Stulln only and Stulln plus vision training. The investigators' theory predicts that the efficacy of Stulln will be augmented by vision training.

Criteria

Inclusion Criteria:

• Be between 18 and 45 years of age.

• Have normal/corrected-to-normal monocular acuity of better than 20/25 for both eyes.

• Have normal contrast sensitivity.

• Be a native English speakers or possess college-level English reading proficiency.

• Have a current optical prescription (obtained less than 2 years ago).

• Have accommodative dysfunctions, including reduced accommodative amplitude, range, facility and endurance.

Exclusion Criteria:

• Have no prismatic correction.

• No clinically significant ocular pathology (e.g., cataract, keratoconus, dry eye, diabetic retinopathy, or age-related macular degeneration) that would limit the effectiveness of vision training.

• Have no binocular dysfunction, including amblyopia, strabismus, and other binocular diseases that would impede accommodative training.
