Filter by:This study will evaluate the safety and IOP-lowering effectiveness of XEN in patients with Angle Closure Glaucoma.
To evaluate the influence of superior versus temporal laser peripheral iridotomy location on post-operative visual acuity and contrast sensitivity.
Primary angle-closure glaucoma (PACG) is common, phacotrabeculectomy is associated with a significant risk of complications.The Ex-PRESS shunt was introduced as a modification to trabeculectomy, with the theoretical advantages of reduced complications.Our purpose is to perform a prospective study to evaluate the clinical outcomes and safety of the Ex-PRESS shunt with cataract surgery for PACG patients coexisting cataract.
The purpose of this study is to determine if location of laser peripheral iridotomy (LPI) that is the standard of care treatment for angle closure glaucoma is related to changes in post-operative intraocular pressure (IOP), endothelial cell count,anterior chamber angle morphology and onset of new visual disturbances.
The goal of this study is to evaluate the efficacy and safety of the novel form of trans-scleral cyclophotocoagulation using micropulse diode laser and trans-pars plana treatment (Micropulse TSCPC, mTSCPC MP3, IRIDEX CYCLO G6™ Glaucoma Laser System, CA, USA) in adults for the treatment of uncontrolled glaucoma.
Clear-lens extraction has been considered as first-line therapy for primary angle closure glaucoma(PACG) and application of toric intraocular lens (IOLs) leads to better postoperative visual acuity, yet little is known about the prevalence of corneal astigmatism in PACG patients. We intend to make biometry examination for Chinese PACG patients, to obtain keratometry (K) , axial length (AL) and so on, and demographics data will also be recorded. We will study the prevalence of corneal astigmatism before glaucoma surgery in Chinese patients with PACG. Furthermore, differences of corneal astigmatism between primary angle-closure glaucoma and cataract patients will be explored. Finally, the prevalence of corneal astigmatism before glaucoma surgery in Chinese patients with PACG will be portrayed and can be instructive to the IOLs' manufactering.
To evaluate the safety and efficacy of the XEN® Gel Stent in mild to moderate glaucoma patients undergoing glaucoma surgery.
To evaluate the clinical efficacy (intraocular pressure reduction , success rate, the number of antiglaucoma medication) and safety of ab interno trabeculectomy (AIT) with Trabectome in Chinese PACG .
To assure the quality of follow-up and treatment, data of glaucoma patients are stored and evaluated after anonymisation.
The purpose of this study is to evaluate the efficacy and need for prescribing anti-inflammatory topical drops to patients undergoing laser peripheral iridotomy.
