From pathogenic considerations to a simplified decision-making schema in dry eye disease

Area of Science:

• Ophthalmology
• Ocular Surface Disease
• Tear Film Dynamics

Background:

• The traditional classification of Dry Eye Disease (DED) into tear deficiency or instability is insufficient.
• DED involves a complex interplay of objective findings, subjective symptoms, and mechanisms like hyperosmolarity and inflammation.
• Ocular surface abnormalities can disrupt tear dynamics, creating a self-sustaining cycle leading to severe DED.

Purpose of the Study:

• To propose a simplified decision-making schema for ophthalmologists.
• To assist in selecting first-line treatments for DED.
• To guide the adaptation of long-term DED management strategies.

Main Methods:

• Review of current understanding of DED pathophysiology.
• Analysis of the limitations of dichotomous DED classification.
• Development of a practical clinical decision-making schema.

Main Results:

• Evidence suggests a multifactorial etiology for DED, challenging traditional classifications.
• A simplified schema can aid clinicians in managing DED.
• The proposed schema facilitates initial treatment selection and subsequent adjustments.

Conclusions:

• The complex nature of DED necessitates a departure from simplistic classifications.
• A structured approach can improve the management of Dry Eye Disease.
• Ophthalmologists can benefit from a decision-making tool for personalized DED treatment.
