Filter by:Eligible Glaucoma patients will undergo pre-surgery examination including: medicines list, blood tests and ECG. On surgery day: intraocular pressure (IOP) will be measured. Then a sub-conjunctival injection of Mitomycin C will be administered . The Minimally Invasive Micro Sclerostomy (MIMS) procedure is designed to create a drainage channel at the sclera-corneal junction by penetrating through the wall [scleral tissue] . MIMS procedure may be combined with cataract surgery. Patients will be followed up to 24 weeks post operation.
Purpose: Characterize changes in intraocular pressure (IOP), IOP-lowering medications, and visual acuity (VA) through 3 years in patients undergoing combined phacoemulsification and excisional goniotomy with the Kahook Dual Blade (phaco-KDB), with simultaneous goniosynechialysis in cases of angle-closure glaucoma, by a single surgeon (A.H.) in King Fahd Hospital of the University, Dammam, Saudi Arabia. Methods: Prospective, non-comparative, uncontrolled, non-randomized interventional case series. Consecutive patients with medically-treated glaucoma and visually-significant cataract underwent combined surgery. Subgroup analysis of glaucoma subtypes was performed.
The purpose of this study is the investigation of biomechanical properties of the cornea using computer-aided data analysis. Currently, it is known that keratoconus and glaucoma are ocular disease that are associated with biomechanical alterations of the cornea. Corneal ectasia, especially keratoconus, is a corneal disease that leads to an irreversible loss of visual acuity while the cornea becomes steeper, thinner and irregular. For these patients, surgical intervention (e.g. corneal cross-linking) is performed, in case of disease progression. In glaucoma, the information about corneal alterations serves in two ways, first, correct measurement of intra ocular pressure (IOP); second, early diagnosis of suspects before visual field defects are detectable. Especially, the Corvis ST is an air-puff tonometer that measures intraocular pressure, corneal thickness (CCT) as well as dynamic corneal response (DCR) parameters. Most of the DCR parameters are affected by IOP and CCT: Therefore, algorithm are needed to determine parameters without impact of IOP and CCT that are describe the biomechanical properties of the cornea.
This is a randomized prospective study of post-operative surgical outcomes and complication rates in patients with a Baerveldt 350 implant vs the Ahmed ClearPath implant. Each subject will be randomized to the Baerveldt group or ClearPath group at the time of consent for the study.
Elevated IOP is a key risk factor for the progression of glaucoma. IOP is subjected to diurnal fluctuation in healthy individuals and higher fluctuation in POAG . So, once-daily antiglaucoma drugs must have consistent efficacy throughout the day. Prostaglandin analogues (PGAs) have become the first-line drops for medical treatment of glaucoma worldwide. In our study, we compare between the efficacy and tolerability of Latanoprost 0.005%, Travoprost 0.004% and Tafluprost 0.0015% on diurnal IOP fluctuation in patients having POAG, IOP fluctuation was assessed before treatment , then 2 weeks and 6 weeks after. A comparable and significant reduction in IOP fluctuation occurred in the 3 groups. Side effects were mild and tolerable.
European Nutrition in Glaucoma Management (ENIGMA) trial will evaluate the effect of 18-month supplementation with lutein, zeaxanthin and meso-zeaxanthin on macular pigment (MP) levels, vision, cognition and serum biomarkers of inflammation and oxidative stress in glaucoma patients. This study comprises a randomised, placebo controlled and double masked clinical trial designed to establish MP response to supplementation with lutein, zeaxanthin and meso-zeaxanthin over an 18-month period. The study will also investigate the relationship between macular pigment, cognitive function, oxidative stress and inflammation, and determine the impact of dietary supplementation on vision, retinal structure, quality of life and cognitive function among glaucoma subjects.
Glaucoma encompasses a collective group of optic neuropathies characterized by progressive degeneration of retinal ganglion cells and their axons, resulting in cupping, a distinctive appearance of the optic disc, and a pattern of visual loss
The Xen-45 gelatin microstent is a novel, bleb-forming microinvasive glaucoma surgery (MIGS). Despite demonstrating similar efficacy and safety to trabeculectomy (traditional surgery), the Xen-45 gelatin microstent continues to suffer from occasional surgical failure due to fibrosis of the filtering bleb, and obstruction of the stent. During surgery, placement in a surgery known as supra-tenon's space is believed to maximize aqueous outflow, while preventing obstruction, limiting fibrosis of the bleb, and promoting long-term patency. Despite the theoretical merits, long-term data of outcomes after targeted supra-tenon's placement is needed to fully assess its potential in improving Xen-45 microstent outcomes.
Topical Anesthesia will be compared to Analgosedation for pain control in Micropulse Transscleral Laser Treatment for Glaucoma (MP-TLT).
By comparing the preoperative data and postoperative data of 9 patients of microspherophakia, we concluded that the 6-point transscleral suture fixation of a 3-looped haptics posterior chamber intraocular lens (PC-IOL) through scleral pockets was a feasible method of PC-IOL implantation in the surgical treatment of microspherophakia.
