Central Corneal Thickness in Glaucoma

Completed

• Conditions: Exfoliation Syndrome

• Registration Number: NCT01023997
• Lead Sponsor: Aristotle University Of Thessaloniki

Brief Summary

The purpose of this study is to compare the central corneal thickness measurement in patients with exfoliation syndrome, exfoliative glaucoma, primary open-angle glaucoma, ocular hypertension and normal controls and to evaluate the value of corneal thickness in the diagnosis and management of glaucoma.

Detailed Description

To compare the central corneal thickness measurement in patients with exfoliation, primary open-angle glaucoma, ocular hypertension and normal controls and to evaluate the value of corneal thickness in the diagnosis and management of glaucoma. Prospective study in progress. Randomly selected patients undergo a comprehensive ophthalmic exam which includes 2 separate pachymetry measurements in 2 different examinations at the same time of the day (10:00 am) with 3 different pachymeters. The values obtained are correlated with a number of other glaucoma parameters. A thinner cornea may represent a specific attribute and an additional risk factor for patients with exfoliation. Evaluation of corneal thickness is an important exam in the management of patients with exfoliation.
