Brief Summary:
The purpose of this study is to determine if there is a measurable change in visual function as a direct result of the application of osteopathic cranial manipulative medicine. The study will also attempt to determine whether any changes noted remain after withdrawal of the treatment.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 113 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Effect of Osteopathic Cranial Manipulative Medicine on Visual Function
Study Start Date : August 2003
Actual Primary Completion Date : November 2005
Actual Study Completion Date : November 2005

Arm Intervention/treatment
Experimental: Cranial manipulation

Assessment for cranial strain patterns, followed by indirect cranial manipulation to treat dysfunctions found on assessment, followed by reassessment.

Repeated for a total of eight visits no less than one week apart.

Procedure: Cranial Manipulation
Performed by exaggerating the motion asymmetry with a minimum of pressure (a few ounces) and holding the position until the motion becomes symmetrical.
Other Names:
  • Osteopathy in the Cranial Field
  • Osteopathic Cranial Manipulative Medicine

Sham Comparator: Sham/placebo
Assessment for cranial strain patterns, followed a laying on of hands, followed by reassessment. Repeated for a total of eight visits no less than one week apart.
Procedure: Sham/Placebo
A laying on of hands with no actual treatment being performed.




Primary Outcome Measures :
  1. Distance Visual Acuity [ Time Frame: Weekly for 16 weeks ]
    Measurement of visual acuity in each eye by number of letters read correctly on ETDRS chart.

  2. Accommodative System Testing [ Time Frame: Weekly for 16 weeks ]
    Accommodative amplitude testing using a Donder push-up card.

  3. Local Stereoacuity Testing [ Time Frame: Weekly for 16 weeks ]
    Measured by Random Dot E test.

  4. Pupillary Size Testing [ Time Frame: Weekly for 16 weeks ]
    Measurement of pupil size (each eye) in bright and dim light.

  5. Vergence System Testing [ Time Frame: Weekly for 16 weeks ]
    Assessed by Cover Test with Prism Neutralization and Near Point of Convergence
