Autologous Serum Eye Drops for Severe Dry Eye: Protein Factors and Response

Official title: Study of Proteomic Factors in Patients With Severe Dry Eye Syndrome Treated With Autologous Serum Eye Drops. Single-center Study.

Run by Centre Hospitalier Universitaire de Saint Etienne · NCT07632534 · Data updated 2026-11-12

This study tests whether the protein makeup of a patient’s own serum eye drops explains how well those drops work for severe dry eye.

Is this trial a fit for you?

Likely a good fit

Adults over 18 with severe, refractory dry eye who are AS-naïve and managed by Saint-Etienne University Hospital ophthalmology services.

Probably not a fit

Patients with dry eye not driven by factors related to serum protein composition may see little or no benefit from this approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial examines whether differences in the protein composition of autologous serum eye drops are linked to how patients with severe dry eye respond to treatment. Participants are adults with refractory dry eye who have not previously used autologous serum and are being treated at Saint-Etienne University Hospital. Data collected from medical records will be analyzed to identify protein factors associated with clinical response. The study focuses on exploring biological markers that may predict benefit from autologous serum therapy. No randomization or placebo is described, and the approach emphasizes observational data alongside the serum treatment.

Why it matters

Potential benefit: If successful, the study could help tailor autologous serum eye drop therapy to individual patients based on serum protein profiles.

How similar studies have gone: Previous work suggests autologous serum can help severe dry eye, but the predictive value of serum proteins remains uncertain and this study seeks to clarify that.
