Keratograph 5M As A Useful And Objective Tool For Evaluating The Ocular Surface In Limbal Stem Cell Deficiency.

Purpose: In limbal stem cell deficiency, both the Ocular Surface Disease Index (OSDI) questionnaire and tear break-up time (BUT) are comparable between traditional methods and the Keratograph 5M. In this study, we aimed to correlate OSDI with Keratograph 5M interviewed OSDI, as well as slit-lamp tear BUT with Keratograph 5M noninvasive tear break-up time (NIKBUT) in limbal stem cell deficiency.

Patients And Methods: Thirty-eight limbal stem cell-deficiency patients (76 eyes) from Virgen Macarena-Rocio Hospital (Seville, Spain) underwent this diagnostic test study.

In vivo confocal microscopy indicates an inverse relationship between the sub-basal corneal plexus and the conjunctivalisation in patients with limbal stem cell deficiency.

Background/aims: Limbal stem cell deficiency (LSCD) is characterised by a marked decrease in limbal stem cells. It is classified primarily using subjective slit-lamp observations. In vivo confocal microscopy (IVCM) can non-invasively provide objective information on the condition of the limbal niche, the corneal epithelial basal cell density and the corneal sub-basal nerve plexus density (SND).
