Uddevalla Skövde Transscleral Micropulse Study
Sponsor: Vastra Gotaland Region
Summary
Micro pulse transscleral laser treatment (MP-TLT) is a relatively new method to reduce the intraocular pressure (IOP) in glaucoma. New recommendations regarding the treatment protocol has recently been developed and was published 2022. The overall objective is to evaluate the efficacy and safety of the proposed treatment method in an independent study. In addition, the outcome of MP-TLT in patients with pseudoexfoliation glaucoma, which is relatively common in the Nordic countries, and primary open angle glaucoma will be studied separately. The IOP change over the course of one year will be monitored, as well as success rate and survival. Further, patient-reported discomfort from the treatment and the occurrence of any adverse events or complications will be studied.

Interventions
Topical lidocaine
Patients will receive topical anesthesia with tetracaine hydrochloride 1% three times, 5 minutes apart. Then, lidocaine gel 2% will be applied on the surface of the eye and refilled as needed for 10 minutes, as well as manipulated for a good coverage.
MP-TLT
Micro pulse transscleral laser treatment will be performed with the Iridex CycloG6 laser with the revised P3 probe, according to the recent consensus recommendations. In brief, this includes MP-TLT with 2500 mW, 31.3% duty cycle, four 20 second sweeps per hemisphere, avoiding the 3 and 9 o'clock meridians and sectors with scleral thinning.
