Ocular Surface Disease Index (OSDI)

The Ocular Surface Disease Index (OSDI) is a questionnaire used by eye care professionals to assess the severity of dry eye symptoms and their impact on daily life. It asks about symptoms like dryness, discomfort, and visual difficulties, as well as how often these issues occur and affect activities like reading, working on a computer, or driving. The results help determine how severe the condition is and guide treatment decisions. By capturing the patient's experience, the OSDI provides valuable insight into the extent of ocular surface problems from the patient’s perspective.
