Study Details

Study Description

Brief Summary

The goal of this study is to measure lens fluorescence in normal subjects at various chronological ages that could serves as a guide to clinicians in determining changes in eye health. A measure of lens fluorescence can be used by clinicians as an indication of degenerative changes occurring in the lens of the eye.

    Arms and Interventions

    Arm Intervention/Treatment
    Normal Healthy

    Normal, healthy males and females between the ages of 21 and 70 with healthy eyes as determined by a standard ophthalmic examination.

    Outcome Measures

    Primary Outcome Measures

    1. Lens fluorescence [Day 1]

      evaluate the ability of the ClearPath DS-120 instrument to measure the fluorescence and scattering responses of the human crystalline lens in a normal subject population with healthy eyes (as determined by standard comprehensive ophthalmic examination).

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    21 Years to 70 Years
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    Yes
    Inclusion Criteria:
    • Persons between the ages of twenty-one (21) and seventy (70). Best efforts shall be made to include as many patients as possible between the ages of thirty-five (35) and sixty (60).

    • Subject must be able to read or understand and give informed consent.

    • Pass the medical health history and comprehensive ophthalmic examination (which is determined by the investigator if the test subject has a normal ophthalmic examination and is in overall good health). Ophthalmic examination includes a clinical evaluation of the subject's eyes and a complete manifest refraction producing a best aided visual acuity of <20/40.

    Exclusion Criteria:
    • Subject has had the crystalline lens removed from the study eye or has had the crystalline lens removed and replaced with an intraocular lens (IOL) implant in the left eye.

    • Subject has been clinically diagnosed with cataracts in the study eye.

    • Subject has had a fluorescence angiogram within the last six months.

    • Subject has undergone a treatment using photodynamic drugs within the last year.

    • Subject has Type I or II diabetes or is not deemed healthy from Demographic and Health Questionnaire or the comprehensive eye exam.

    • Subject was fit with contact lens within the last 30 days.

    • Subject has ocular surface (dry eye) disease.

    • Subject is unable to cooperate with or understand clinical instructions.

    • Subject is unable to complete test sequence
