Flare Photometry in Uveitis Patients

This is a cross sectional study of a novel non-invasive optical flare photometer (OFAM). Patients meeting the inclusion/exclusion criteria will receive a standard eye examination including a slit lamp examination to collect ocular flare data. In addition to the standard eye examination, subjects will receive flare measurements using the OFAM device.

  • Ability to understand and willingness to sign a written informed consent document.
  • To be eligible for the uveitis arm of the study subjects must have active anterior chamber uveitis in one or both eyes as determined by a physician
  • To be eligible for the non-inflammatory arm of the study the study subjects must have no ocular inflammation in either eye as determined by a physician.

Treatment and study plan

Primary outcomes

  1. Establish OFAM algorithms for quantitation of ocular flare

    Time frame: 3 months

    OFAM algorithms for quantitation of ocular flare will be established by comparing the output of the OFAM device to the flare measurements obtained during the standard slit lamp examination.

Secondary outcomes

  1. Determine the impact that various potential confounders such as age and sex have on OFAM Measurements

    Time frame: 3 months

    OFAM data for various sub-groups (age and sex) will be compared in order to evaluate the degree to which each sub-group acts as a confounder for OFAM measurements.
