Filter by:There are several publications that have demonstrated the protective role of cataract surgery against the development of long-term glaucoma, especially in cases of pseudoexfoliation glaucoma (PXFG). Cataract surgery in patients with pseudoexfoliation (PXF) is a procedure with higher rates of complications due to its smaller pupillary diameter and its greater zonular weakness, so lens extraction performed earlier could possibly reduce intra and postoperative complications. Given the severity and high prevalence of PXFG in our environment, investigators proposed a randomized clinical trial to evaluate the efficacy of cataract surgery in reducing the intraocular pressure (IOP) at 12 months and thereby change the course of the disease. The control group will have glaucoma treatment according to standard practice.
This study aims to evaluate the effect of a single session of micropulse laser trabeculoplasty (MLT) on cornea in eyes with primary open glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG).
It has been hypothesized that the biomechanical properties of the optic nerve head and/or sclera play a role in the development of glaucoma. One approach of gaining insight into the biomechanical properties of the eye by the means of clinical studies is based on the Friedenwald equation, representing a pressure-volume relationship. This equation represents the so called ocular rigidity, which expresses the elasticity of the globe. In order to be able to solve the equation, measurements of fundus pulsation amplitude (FPA) with laser interferometry and dynamic contour tonometric assessment of the pulse amplitude (PA) have to be performed. In addition choroidal thickness will be assessed with OCT before and after trabeculectomy, since results in choroidal thickness measurements in patients with glaucoma are controversial. The focus of this study lies on the changes of ocular rigidity and choroidal thickness after surgical trabeculectomy in patients with primary open angle glaucoma (POAG) or pseudoexfoliation glaucoma (PEX).
The purpose of this research study is to hypothesize that Simbrinza will achieve a decrease in intraocular pressure and increase in ocular perfusion pressure throughout the diurnal and nocturnal periods. The primary aim of this study will be to determine the effects of Simbrinza at multiple intervals throughout a 24-hour period. The secondary aim will be to compare these to those of timolol.
The type of anti-inflammatory medication used post selective laser trabeculoplasty (SLT) may have an impact on the intra-ocular pressure (IOP) lowering effect of SLT. This study will evaluate the IOP lowering effect of SLT following the topical administration of one of the following: prednisolone 1%, ketorolac 0.5% or artificial tears.
