Collection of Ocular Surface Impressions Cytology of the Living Eye From Patients With Dry Eyes or Limbal Stem Cell Deficiency.

Collection of Ocular Surface Impressions Cytology of the Living Eye From Patients With Dry Eyes or Limbal Stem Cell Deficiency.

In order to develop innovative biomarkers for the diagnosis of two ocular surface pathologies, Dry Syndrome (DS) and Limbic Stem Cell Deficiency (LSCD), human cells from the ocular surface will be collected in order to test these biomarkers ex vivo.

To collect them, cytological fingerprints of the ocular surface are made using filter paper applied to the surface using a commercially available EC (European Conformity)-marked medical device, called EYEPRIM.
