A biomarker is a “characteristic that is measured as an indicator of normal biological
processes, pathogenic processes, or responses to an exposure or intervention, including …

Purpose: To test the validity of ocular surface assessment tools offered by a corneal
topographer (Oculus Keratograph 5M). Methods: Over 9 months, 296 eyes were imaged and …

Imaging has become indispensable in the diagnosis and management of diseases in the
posterior part of the eye. In recent years, imaging techniques for the anterior segment are …

Purpose: To measure the correlation between subjective symptom score, conventional
clinical tests, and Fourier-domain optical coherence tomography (FD-OCT) of lower tear …

Many different parameters exist for the investigation of tear film dynamics. We present a new
tear meniscus segmentation algorithm which automatically extracts tear meniscus area …

Purpose To evaluate the precorneal tear film (PCTF) and lipid layer (TFLL) thicknesses and
thinning rates in meibomian gland dysfunction (MGD) using a combined ultra-high …

To evaluate the diagnostic power of tear meniscus measurements using anterior segment
swept source optical coherence tomography (SS-OCT) for dry eye and suspected dry eye …

Biomarkers provide a powerful and dynamic approach to improve our understanding of the
mechanisms underlying ocular diseases with applications in diagnosis, disease modulation …

Objectives: The purpose of this review is to briefly outline current scientific evidence on the
potential role of tear analysis and ocular surface evaluation in diagnosis and monitoring of …

Purpose The purpose of this work was to gather preliminary data in normals and dry eye
subjects, using a new, non-invasive imaging platform to measure the thickness of pre …
