Trial summary

The mechanism of the eye movement anomalies seen in dyslexic patients is not well defined. Some optometrists use observational eye movement tests as screening devices for dyslexia and advocate eye movement therapy as a treatment option for dyslexia. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 7 to 13 years
  • All sexes
  • Healthy volunteers accepted
  • Child

Study population: Children with reading disorders, eye movement disorders or control (normal reading and eyemovements)between the ages of 7 and 13 are eligible for the study.

Who may be able to join

  • 1. Age 7 to 13 (Must be in at least 2nd grade, but not higher than 8th grade) 2. Complete ophthalmic examination performed by a pediatric ophthalmologist and orthoptist.
  • 3. All ocular structures must be within normal limits. 4. Best corrected visual acuity must be equal to or better than 20/30 in each eye.
  • 5. Group 1:

  • Children with a reading disability may not have any ophthalmic anomaly determined by testing as described above. This includes but is not limited to amblyopia, strabismus, nystagmus, or any organic disease.
  • 6. Group 2
Show all 9Show fewer
  • Eye movement disorder confirmed by testing by a pediatric ophthalmologist and/or orthoptist b. All other ocular structures must be within normal limits (including visual acuity).

About this study

Official title: Reliability of Clinical Eye Movement Tests as Screening Devices for Reading Disabilities

The mechanism of the eye movement anomalies seen in dyslexic patients is not well defined. Some optometrists use observational eye movement tests as screening devices for dyslexia and advocate eye movement therapy as a treatment option for dyslexia. The reliability of the clinical eye movement tests and the efficacy of the eye movement therapies have not been determined.

Saccades are the fast eye movements that move our eyes from one word to the next when we read. The eye movement recordings from patients diagnosed with reading disorders, extra ocular muscle imbalances and control patients (no learning disability or eye movement disorder) will be analyzed and compared. The sensitivity and specificity of detecting reading disorders will be determined for the Visagraph III and the Readalyzer. Although these clinical tests are frequently used to diagnose saccadic inaccuracies and diagnose dyslexia in school aged children, the validity of these clinical screening tests has not been determined.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity and specificity of clinical eye movement devices

    The primary analysis will be determining the sensitivity and specificity of the eye movement recording devices to recognize reading disorders. The sensitivity (true positive rate) of the eye movement recorders will be determined by the ability of each device to recognize children with reading disorders in Group 1. The specificity of the recorders will be determined by calculating the false positives in group 2 (eye movement disorders), and group 3 (control subjects).

    Measured: June 2014

Secondary outcomes (1)
  1. Comparison of eye movement characteristics amongst patients with reading disorders, eye movement abnormalities and control subjects.

    The secondary analysis will be a study group comparison of eye movement results for each reading variable using an analysis of covariance (ANCOVA) model. The 6 calculated reading variables are listed below and will be individually compared amongst the three groups.

    1. Fixations / 100 words ii. Regressions / 100 words iii. Average span of recognition iv. Average duration of fixation v. Reading rate with comprehension vi. Grade level Efficiency

    Measured: June 2014

Questions about this trial

What is this clinical trial studying?

An observational study of Reading Disability and Dyslexia, run by Scripps Health at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 22 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Lack of enrollment). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity and specificity of clinical eye movement devices (time frame: June 2014). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Nov 2023.
