Project Description

Please note that we are a research service provider, not a pharmacy or clinic, so we are unable to see patients and do not offer diagnostic and treatment services for individuals.

Tear

Tear fluid, the thin layer of liquid that coats the surface of the eye, is a remarkably rich and accessible biofluid that holds immense potential as a window into the health and pathophysiology of the ocular system. Unlike invasive tissue biopsies, tear samples can be collected non-invasively and provide a direct reflection of the biochemical and molecular state of the eye.

Tear fluid contains a diverse array of proteins, lipids, metabolites, and nucleic acids that can serve as informative biomarkers for a wide range of ophthalmic conditions, from dry eye disease and allergic conjunctivitis to keratoconus and even systemic diseases with ocular manifestations. At Protheragen, we provide tear samples from patients with various ophthalmic diseases as well as healthy donors to meet the different needs of our customers.

The Importance of Tear Sample Analysis in Ophthalmic Diseases

Tear sample analysis is a cornerstone in the field of ophthalmology, offering a non-invasive approach to diagnose and monitor various ophthalmic diseases. Tears contain a wealth of biomarkers, including proteins, nucleic acids, and metabolites, which reflect the physiological and pathological states of the eye. The analysis of these biomarkers allows for the early detection of diseases, assessment of disease progression, and monitoring of therapeutic responses.
