Dry Eye Disease Epidemiology Summary

• Dry Eye Disease is a multifactorial ocular surface disorder caused by tear film instability, resulting in dryness, irritation, visual disturbances, and inflammation. It is broadly classified into evaporative dry eye (approximately 80% of cases) and aqueous-deficient dry eye, with many patients exhibiting a mixed form.
• The Tear Film & Ocular Surface Society (TFOS) highlights that heterogeneity in Dry Eye Disease diagnostic definitions, testing practices, and severity classification, together with variable recognition of mild or intermittent disease, limits the comparability of prevalence estimates and may contribute to underestimation of the overall disease burden.
• In 2025, the United States accounted for approximately 23 million diagnosed prevalent cases of Dry Eye Disease, representing a substantial share of the overall disease burden across the 7MM.
• Dry Eye Disease remains substantially underdiagnosed, driven by poor symptom–sign correlation, heterogeneous clinical presentation, and variability in diagnostic practices, which can delay disease recognition and lead to underestimation of the true epidemiological burden.
• In Japan, females accounted for approximately 80% of Dry Eye Disease cases in 2025, compared with 20% among males, indicating a marked female predominance.
• The Tear Film & Ocular Surface Society (TFOS) also emphasizes the need for more longitudinal and population-based epidemiological data, as limited evidence on disease natural history and progression constrains accurate characterization of the Dry Eye Disease burden.
• Dry Eye Disease diagnosis integrates patient-reported symptoms with objective assessments of tear-film stability, tear production, and ocular-surface damage. Evaluation commonly begins with validated questionnaires such as OSDI and DEQ-5, followed by clinical testing to characterize disease severity and underlying abnormalities.

Dry Eye Disease Understanding

Dry Eye Disease Overview and Diagnosis

Dry Eye Disease is primarily classified into two main types based on cause: Evaporative Dry Eye (most common, ~80%) and Aqueous-Deficient Dry Eye. These types are not mutually exclusive, and many individuals suffer from a mixed type. Dry Eye Disease is generally classified into three main types based on cause: aqueous deficient (low tear production), evaporative (high tear evaporation), and mixed (both). Proper diagnosis is key, as treatments differ. The condition often stems from Meibomian gland dysfunction, environmental factors, or underlying autoimmune conditions.

Diagnosis involves a comprehensive eye exam assessing tear quantity and quality, often using tests like the Schirmer test (measuring tear volume with strips), slit-lamp exam (evaluating surface damage), and tear break-up time (TBUT) to measure stability. Symptoms include burning, irritation, and blurred vision, caused by insufficient tear production or rapid evaporation

Dry Eye Disease Epidemiology

Key Findings from Dry Eye Disease Epidemiological Analysis and Forecast

• As of 2025, the total diagnosed prevalent cases of Dry Eye Disease across the 7MM are estimated at approximately 58 million cases, reflecting the significant and growing burden of ocular surface disease.
• In 2025, the gender-specific diagnosed prevalent cases of Dry Eye Disease across the 7MM were estimated at approximately 35% in males and 65% in females, demonstrating a substantially higher disease burden among women.
• Age-specific analysis indicates that individuals aged 50 years and above represented the largest proportion of diagnosed Dry Eye Disease cases across the 7MM in 2025, highlighting the strong association between aging and disease prevalence.
• In 2025, the severity-specific diagnosed prevalent cases of Dry Eye Disease in the UK were estimated to comprise approximately 45% mild, 20% moderate, and 35% severe cases.
