  Purpose

The purpose of this study is to determine the effect of enhancements to the myVisionTrack® in regards to patient compliance and test-retest variability. Additionally, the ability of myVisionTrack® to detect changes in vision function will be evaluated.

The results of this study will provide the basis for patient self-monitoring of visual function with the myVisionTrack®, and for reporting, storage, and maintenance of collected data. The myVisionTrack® is intended to be used remotely by patients to monitor their disease. In the case of significant changes, patients will be prompted to visit their ophthalmologist. It is hypothesized that this can lead to earlier detection of disease progression, which, in turn, can lead to earlier treatment and better prevention against vision loss due to diabetic retinopathy (DR).

Primary Outcome Measures:
  • Test efficacy of the test algorithm improvements [ Time Frame: Twelve months ] [ Designated as safety issue: No ]
    To test the efficacy of test algorithm improvements and usability enhancements on the overall rate of patient compliance and on test-retest variability.


Secondary Outcome Measures:
  • Refine the decision rule [ Time Frame: Twelve months ] [ Designated as safety issue: No ]
    To refine the decision rule so as to select optimal cutoff values to achieve desired sensitivity and specificity of self-test

  • Can improved testing algorithm minimize test time? [ Time Frame: Twelve months ] [ Designated as safety issue: No ]
    To determine if the improved testing algorithm can minimize the length of testing while maintaining or improving accuracy

  • Assess patient satisfaction with the test [ Time Frame: Twelve months ] [ Designated as safety issue: No ]
    To assess patient satisfaction regarding the use of myVisionTrack™

Groups/Cohorts Assigned Interventions
Home vision monitoring using myVisionTrack®
Patients diagnosed with diabetic retinopathy/diabetic macular edema requiring treatment at the time of recruitment into the study.
Device: Home vision monitoring using myVisionTrack®
Patients will be asked to test their vision at home twice per week using myVisionTrack® during the study period.
Other Name: myVisionTrack® Model 0004

  Eligibility

Ages Eligible for Study:   40 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients with diabetic retinopathy requiring treatment

Criteria

Inclusion Criteria:

  • DR or AMD requiring treatment at time of study initiation
  • Macular edema involving the central subfield based on clinical judgment
  • No noticeable central subfield atrophy

Exclusion Criteria:

  • Any ocular pathology other than DR or AMD
  • Any other concurrent systemic illness affecting the retina and visual function
  • Dementia or other neurological or psychological limitation that would prevent patients from performing self-testing of visual function
  • Past (within the prior 6 months) or current use of, or likely need for, systemic medications that are known to be toxic to the lens, retina, or optic nerve
  • Use of investigational drugs at the time of screening, or within 60 days (excluding vitamins and minerals)
  • Pregnancy
