Understanding dry eye disease is essential for effective treatment and improved quality of life. One of the most reliable tools used by eye care professionals to evaluate the severity and impact of dry eye symptoms is the OSDI (Ocular Surface Disease Index) questionnaire. The OSDI dry eye questionnaire PDF serves as a practical resource for patients and clinicians alike, offering a standardized method to measure symptoms, their frequency, and their effect on daily activities. In this comprehensive guide, we will explore everything you need to know about the OSDI questionnaire, including its purpose, structure, how to access the PDF, how to interpret results, and tips for effective use.
What Is the OSDI Dry Eye Questionnaire?
Definition and Purpose
The OSDI is a validated, patient-reported questionnaire developed to quantify the severity of dry eye disease and its impact on patients' quality of life. It is widely recognized in both clinical practice and research for its reliability and ease of use.
Key purposes include:
- Assessing the severity of dry eye symptoms
- Monitoring treatment effectiveness over time
- Facilitating communication between patients and eye care providers
- Standardizing symptom measurement in clinical studies
Development and Validation
The OSDI was developed by the Tear Film & Ocular Surface Society (TFOS) and validated through multiple studies to ensure it accurately reflects patient experiences. Its concise format allows for quick administration while providing meaningful insights.
Structure of the OSDI Questionnaire
Content and Sections
The OSDI consists of 12 questions divided into three sections:
1. Ocular symptoms (e.g., dryness, sensitivity to light)
2. Visual function (e.g., reading, working on a computer)
3. Environmental triggers (e.g., air conditioning, wind)
Questions are designed to assess:
- Frequency of symptoms over the past week
- The degree of discomfort or difficulty experienced
- The impact of symptoms on daily activities
Scoring System
Responses are scored on a 5-point Likert scale:
- 0 = None
- 1 = Sometimes
- 2 = Often
- 3 = Usually
- 4 = All the time
Calculating the OSDI score:
- Sum the scores of all answered questions
- Multiply the total by 25
- Divide by the number of questions answered
Result interpretation:
- 0-12 = Normal or minimal symptoms
- 13-22 = Mild dry eye
- 23-32 = Moderate dry eye
- 33-100 = Severe dry eye

Integrating the OSDI into Dry Eye Management
Clinical Workflow
- Administer the questionnaire during initial assessment
- Use scores to determine severity and treatment options
- Reassess periodically to evaluate response
- Adjust treatment plans accordingly
Complementary Tests
While the OSDI provides valuable subjective data, it should be combined with:
- Tear film break-up time (TBUT)
- Schirmer’s test
- Ocular surface staining
- Meibomian gland assessment
This comprehensive approach ensures accurate diagnosis and effective management.
