Abstract:
In order to investigate the effects of laser trabeculoplasty (LT) on diurnal intraocular pressure (IOP) variations in 36 eyes of 30 cases with primary open-angle glaucoma (POAG) in which medical treatment was terminated, the IOP curves, recorded 24 h before as well as 24 h and 12 weeks after LT were compared. Twelve weeks after LT, significant IOP decreases were observed: 36.42% in the mean IOP, 29. 77% in the mean peak IOP and 50.04% in the mean pressure range. LT might therefore have beneficial effects on the diurnal IOP variations in cases with POAG.
