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