AS-OCT and Ocular Hygrometer as Innovative Tools in Dry Eye Disease Diagnosis

Dry eye disease (DED) is one of the conditions that most commonly leads patients to visit an ophthalmologist. Fast and accurate diagnosis relieves patient discomfort and spares them from long-term effects on the ocular surface. Many tests used in the diagnosis of DED may be considered subjective as they rely on an experienced observer for image interpretation, resulting in variations in diagnosis. On one hand, the non-contact nature of the anterior segment optical coherence tomography (AS-OCT) device and its rapid image acquisition enable the measurement of the tear meniscus parameter without reflex tearing. On the other hand, an ocular hygrometer allows a rapid, safe, but also efficient, analysis and is associated with low costs and the repeatability of the procedure.

Automated summary

Dry eye disease (DED) is a common condition that leads patients to seek medical attention. Accurate diagnosis is important for relieving patient discomfort and preventing long-term ocular surface damage. Currently, subjective tests may result in variations in diagnosis. However, the use of anterior segment optical coherence tomography (AS-OCT) and ocular hygrometer provide fast, accurate, and cost-effective diagnostic methods.
