Detail
Condition
Dry Eye Disease (DED)
Key Mechanisms
Loss of tear film homeostasis causing tear film instability, hyperosmolarity, ocular surface inflammation, damage, and neurosensory abnormalities leading to corneal higher-order aberrations (cHOAs) and visual impairment
Target Population
Adults aged 18-65 with symptomatic dry eye disease and tear film instability
DED is characterized by tear film instability leading to corneal higher-order aberrations that impair vision beyond lower-order refractive errors.
Severity of DED signs correlates with increased cHOAs, including coma, trefoil, and spherical aberrations.
Ocular surface parameters such as OSDI score, tear break-up time (TBUT), corneal fluorescein staining (CFS), and Schirmer test I (STT-I) are important in assessing DED severity and its impact on corneal aberrations.
Guideline-Based Recommendations
Diagnosis
Use Ocular Surface Disease Index (OSDI) questionnaire with score ≥13 to identify symptomatic DED.
Confirm tear film instability with tear break-up time (TBUT) <10 seconds.
Classify DED severity based on corneal fluorescein staining (CFS) and TBUT according to Chinese Dry Eye Expert Consensus and TFOS DEWS II criteria.
Management
Address tear film instability and ocular surface inflammation to reduce cHOAs and improve visual function.
Consider severity of DED signs when tailoring treatment strategies.
Monitoring & Follow-up
Regular assessment of OSDI, TBUT, CFS, and Schirmer test I to monitor disease progression and treatment response.
Evaluate corneal higher-order aberrations to understand visual fluctuations and symptom persistence despite refractive correction.
Risks
Untreated or severe DED can lead to vision impairment and decreased quality of life.
Persistent tear film instability may cause ongoing visual disturbances not corrected by standard refractive measures.
Patient & Prescribing Data
Patients aged 18-65 with symptomatic dry eye disease and tear film instability confirmed by OSDI and TBUT criteria.
Symptom severity and ocular surface metrics guide management; addressing tear film instability may reduce corneal aberrations and improve visual symptoms.
Clinical Best Practices
Use standardized questionnaires (OSDI) and objective tests (TBUT, CFS, STT-I) for comprehensive DED assessment.
Classify DED severity to inform prognosis and treatment planning.
