IOP Fluctuations in Patients With Primary Open-angle Glaucoma, Before and After Selective Laser Trabeculoplasty

Sensimed AG23 enrolled

Overview

Selective laser trabeculoplasty (SLT) is an increasingly popular treatment modality in early-to-moderate glaucoma patients. SLT has been suggested to reduce IOP more consistently during the nocturnal period than during the diurnal period in a group of medically-treated patients with primary open angle glaucoma (POAG). At present, there is scarce data on SLT effects on the 24-hour IOP pattern in patients with glaucoma and there is no data on the 24-hour effect of SLT in untreated glaucoma patients. The purpose of this study is to assess the changes of IOP over a 24-hour period in patients with glaucoma undergoing SLT.

Outcomes

Primary Outcomes

To evaluate the differences between the nycthemeral IOP patterns recorded with Triggerfish, during two 24-hour periods in patients with POAG, before and after SLT.

* Wake-to-Sleep slopes * Overall variability * Diurnal and nocturnal IOP patterns * Number of peaks

Time frame: 1 months

Secondary Outcomes

To assess IOP patterns of POAG patients during office hours

Overall variability * Diurnal and nocturnal IOP patterns * Number of peaks in the study population before and after SLT

Time frame: 1 month
