Filter by:To assess safety and efficacy of a novel suprachoroidal silicone tube (SST) shunt for the treatment of primary open angle and exfoliative glaucomas.
The aim of this study is to compare the surgical outcomes of the two IOL implantation methods for eyes with cataract and PEX in a single-center and with highly experienced surgeons. The goal is to acquire relevant information regarding these two IOL implantation techniques, which will help surgeons to decide which approach to choose, ultimately resulting in a benefit for patients with PEX syndrome who require cataract surgery. The main questions are: Is there a difference in lens tilt and decentration between the both methods. Is there a difference in the frequency and amount of capsular phimosis between the both methods.
Multicentric evaluation of best corrected visual acuity of the XEN implant versus classic trabeculectomy in open angle glaucoma subjects
The study aims to compare the endothelial cell count in patients with pseudoexfoliation syndrome to the the endothelial cell count in normal patients above the age of 50.
The purpose of the study is to investigate the efficacy of an iStent trabecular microbypass stent compared to selective laser trabeculoplasty in combination with cataract surgery in eyes with exfoliation glaucoma (EXF)
There is increasing evidence that there are genetic risk factors for several forms of glaucoma, such as glaucoma caused by pseudoexfoliation syndrome (PXF) ,primary angle closure glaucoma (PACG) and primary open-angle glaucoma (POAG). The aim of the present prospective, multi-center, case-control study is to identify susceptibility genes/loci for PXF, PACG and POAG using a whole genome association (WGA) approach.
The purpose of this study is to investigate how much selective trabeculoplasty (SLT) influences intraocular pressure (IOP) fluctuations measured with iCare Home rebound tonometry (RTHome) in patients with primary open-angle glaucoma (POAG) or pseudo-exfoliation glaucoma (PEX).
The purpose of this study is to follow and describe the outcomes of patients after selective and pascal laser trabeculoplasty treatment for chronic open-angle glaucoma.
The pseudoexfoliation (PXF syndrome) is caused by production and deposition of extracellular material in the anterior chamber of the eye as well as in other tissues of the body. Approx. 70 million worldwide have a PXF syndrome. After cataract surgery a decentration and subluxation of the intraocular lens (IOL) happens more frequently than in the general population due to a higher incidence of zonular weakness and an increased capsular fibrotic reaction. Decentration, tilt and / or rotation of the lens can reduce the quality of vision. It is believed that the design of the implanted IOL, more precisely the front surface of the IOL has an influence on the extent of capsular fibrosis and contraction. Especially in presence of capsular instability, as it is in patients with Pseudoexfoliation syndrome the design of the IOL has an effect on the post-operative stability. In this study, two different IOL models are compared in terms of their stability. The "Tecnis 1-piece ZCB00" (AMO, USA), with a concave lowering comprising the lens edge and the "Acrysof SA60AT" (Alcon, USA), with a biconvex design are compared. Forty eyes of 20 patients are planned to be included in this study. One eye receives the "Tecnis ZCB00 1-piece "(AMO, USA), while the other eye receives the"Acrysof SA60AT "(Alcon, USA). In which eye which IOL is implanted, is assigned by randomization. To measure the decentration, tilt and rotation of the IOL an examination will be performed before the operation and there will be follow-ups one hour after the operation of the first eye, one hour after the operation of the second eye, three months and twelve months after the operation on the second eye. All measurements will be done without touching the eye.
To evaluate the association profiles of the lysyl oxidase-like 1 gene polymorphisms with pseudoexfoliation syndrome in the Korean population, Genotypes of lysyl oxidase-like 1 gene were analyzed by direct sequencing.
