Outcome Measures

Primary Outcomes (3)

  • Subjective symptoms of Dry Eye

    Ocular Surface Disease Index or OSID is a 12-item questionnaire which assesses dry eye symptoms and the effects it has on vision-related function in the past week of the patient's life. The questionnaire has 3 subscales: ocular symptoms, vision-related function, and environmental triggers. Each question is graded on a scale of 0 to 4, where 0 indicates none of the time; 1, some of the time; 2, half of the time; 3, most of the time; and 4, all of the time. The total OSDI score is calculated as OSDI=\[(sum of scores for all questions answered) × 100\]/\[(total number of questions answered) × 4\]. Total score ranges from 0 to 100 where higher score coresponds with greater disability.

    45 days

  • Tear Break-up Time

    Used to assess for evaporative dry eye disease. To measure TBUT, fluorescein is instilled into the patient's tear film and the patient is asked not to blink while the tear film is observed under a broad beam of cobalt blue illumination. The TBUT is recorded as the number of seconds that elapse between the last blink and the appearance of the first dry spot in the tear film, as seen in this progression of these slit lamps photos over time. A TBUT under 10 seconds is considered abnormal.

    45 days

  • Schirmer tear test

    Evaluates aqueous tear production and is helpful in the assessment of patients with signs and/or symptoms of dry eye. Interpretation: normal aqueous tear production is supported by measurements of \> 15 mm after 5 minutes, and mild-moderate reduction of aqueous production: 5mm-14mm after 5 minutes
