Why We Trust the OSDI
At Alden Leifer, MD and Associates, our commitment to compassionate, personalized care includes using tools that are proven and reliable. The Ocular Surface Disease Index (OSDI) is a scientifically validated questionnaire used worldwide to measure symptom severity and impact on daily life.
- Accurate & consistent: Validation studies show OSDI reliably distinguishes mild, moderate, and severe dry eye and produces repeatable scores when symptoms are unchanged.
- Recommended by experts: Global organizations (e.g., TFOS) include OSDI in dry eye guidelines and clinical research.
- Tracks meaningful change: Clinicians use OSDI over time to confirm when treatment is truly helping.

A Deeper Look at Your OSDI Score
Your personal symptom experience matters. The OSDI’s 12 questions convert your last-week symptoms into a 0–100 score we can track over time.
- What it evaluates: Ocular symptoms (gritty, sore, light sensitivity), vision-related function (reading, night driving, screens, TV), and environmental triggers (wind, low humidity, A/C).
- How it’s calculated: (Sum of answered items × 25) ÷ number of answered items.
- Interpretation: 0–12 normal, 13–22 mild, 23–32 moderate, 33–100 severe.
Your score helps personalize care and measure progress with treatment.
