The Effect of Selective Laser Trabeculoplasty (SLT) on Ocular Rigidity

Not Applicable
Completed
Conditions
Glaucoma
Interventions
Procedure: Selective Laser Trabeculoplasty
Registration Number
NCT01247831
Lead Sponsor
Technische Universität Dresden
Brief Summary

The purpose of this study is to examine the influence of selective laser trabeculoplasty (SLT) on ocular rigidity in glaucoma patients.

Detailed Description

Ocular Rigidity (corneal hysteresis and corneal resistance factor) is measured with the Ocular Response Analyzer (Reichert) before and 4 weeks after SLT (Q-switched 532 nm frequency doubled neodymium yttrium aluminium garnet laser with a spot size of 400 µm and a 3-ns pulse duration). The trabecular meshwork is treated with 100 spots over 360° and an energy of 0,8 mJ.

The purpose is to examine if selective laser trabeculoplasty changes ocular rigidity.
