The Effect of Selective Laser Trabeculoplasty (SLT) on Ocular Rigidity
The Effect of Selective Laser Trabeculoplasty (SLT) on Ocular Rigidity
The purpose of this study is to examine the influence of selective laser trabeculoplasty (SLT) on ocular rigidity in glaucoma patients.
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.
Inclusion Criteria:
glaucoma patients (primary open angle glaucoma, ocular hypertension) over the age of 18 who need further IOP reduction to control their glaucoma
Exclusion Criteria:
other forms of glaucoma (angle closure, secondary glaucoma, congenital, juvenile), acute psychosis, epilepsy
