Posterior Cornea in Primary Open Angle Glaucoma

• Conditions: Glaucoma

• Registration Number: NCT02356094
• Lead Sponsor: Centro Hospitalar do Baixo Vouga

Brief Summary

Characterization of posterior corneal changes in primary open angle glaucoma patients, using Scheimpflug examination.

Detailed Description

A cohort of primary open angle glaucoma (POAG) patients is submitted to Scheimpflug Pentacam examination. The results are compared with a control group of age and central corneal thickness matched healthy subjects
