Forty patients scheduled for MP-TLT by their ophthalmologist will be recruited. One eye per patient is included, based on randomization, even if both are treated. MP-TLT will be performed according to the current recommendations.
Baseline IOP will be calculated as the mean of three separate measurements taken on different days preoperatively. IOP will then be measured 1 week, 1 month, 3 months, 6 months and 12 months after MP-TLT.
The central corneal thickness (CCT), the central retinal thickness (CRT), anterior chamber flare and the visual field (HFA 24-2 faster) will also be measured preoperatively and during follow up.
In accordance with the World Glaucoma Association guidelines, no adjustment for multiple comparisons is planned in this study.
