About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

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

Treatment and study plan

Selective Laser Trabeculoplasty

Procedure

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.

Other names: SLT, ORA

Primary outcomes

  1. 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?

Secondary outcomes

  1. IOP reduction

    Time frame: 4 weeks

    Is there an effective IOP drop after SLT?
