What this trial studies

This study evaluates the diagnostic accuracy and grading consistency of a portable automatic ocular surface imaging device (PAOSID) for assessing dry eye disease (DED). Participants, including those diagnosed with DED and healthy volunteers, will undergo conventional clinical imaging and then use the PAOSID device to capture ocular surface images and videos independently. The study aims to compare the results from the PAOSID with traditional slit-lamp examinations to determine its effectiveness in diagnosing DED. The clinical grading of DED severity will follow established criteria, ensuring a comprehensive assessment of the condition.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18 and older with a diagnosis of dry eye disease or healthy individuals with no ocular conditions.

Not a fit: Patients with other ocular surface disorders or significant vision impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accessible and efficient method for diagnosing dry eye disease.

How similar studies have performed: Other studies have shown promise in using portable imaging devices for ocular assessments, suggesting potential success for this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

1. Participants included individuals with dry eye, based on the TFOS DEWS II (The Tear Film and Ocular Surface Society Dry Eye Workshop II) guidelines,(19) as well as relatively healthy individuals with no ocular conditions who voluntarily agreed to participate in the study.
2. Participants, or their companions or caregivers, who are willing and able to use the study smartphone to capture relevant eye images and videos.
3. Aged 18 years or older.
4. Provide informed consent.

Exclusion Criteria:

1. Participants with ocular surface disorders other than DED that may affect the appearance of the ocular surface (e.g., pterygium, keratitis, corneal scarring) or with any organic pathologies impacting vision (e.g., cataracts, glaucoma, retinal diseases).
2. Patients currently wearing scleral lenses or bandage contact lenses.
3. Unable to cooperate with the PAOSID, such as due to a serious mental illness or brain damage causing loss of limb control.
4. Significant changes in the ocular images since diagnosis due to factors such as postdiagnostic treatment.
