|Condition or disease||Intervention/treatment|
|Glaucoma||Procedure: Selective Laser Trabeculoplasty|
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.

|Study Completion Date :||August 2011|
All of the patients treated with SLT need further IOP reduction for control of their glaucoma.
Procedure: Selective Laser Trabeculoplasty
100 spots with an energy of 0,8 mJ are applied over 360° of the trabecular meshwork of glaucoma patients with a Q-switched 532 nm frequency doubled neodymium YAG Laser.
- change in ocular rigidity [ Time Frame: 4 weeks ]Is there a change in ocular rigidity (corneal hysteresis, corneal resistance factor) as measured with the Ocular Response Analyzer (Reichert) after selective laser trabeculoplasty?
- IOP reduction [ Time Frame: 4 weeks ]Is there an effective IOP drop after SLT?
