Conditions

Summary

BIOCOR is an interventional clinical trial whose main objectives are Objectif are identify molecular biomarker(s) of ocular rosacea and pachychoroid. Endpoints are : Correlation between pachychoroidosis (defined by choroidal phenotype parameters in OCT and autofluorescence) or the stage of ocular rosacea (ROSCO(29) definition) and biological markers selected on the basis of preclinical work (animal model) and by unbiased methods (proteomics, metabolomics, meibum lipidomics). The study of circulating, ocular and functional biomarkers would enable us to confirm our hypothesis and identify patients who could benefit from treatments that regulate the ANS and/or mineralocorticoid pathways.

Interventions

DIAGNOSTIC_TESTSchirmer test paper

This paper is centrifuged and your tears are collected then frozen before analysis. We collect the fat from your tears by scraping the edge of your lower eyelid with small sterile tweezers. All surgical waste will be collected during eye surgeries only if you must have them. During each ocular surgical procedure, the vitreous, subretinal fluids and/or aqueous humor will eventually be recovered when required by the procedure. The rest of the blood samples, not used during diagnostic analyses, will be kept for later analyses. Tears will be collected using a non-invasive and painless method that takes around ten minutes. The tissues (connectiva, cornea, retina, epi-retinal membrane) which must have been removed when required by the surgical procedure will also be preserved.
