Filter by:This is an open-label, observational extension of patients who received POLAT-001 in LipoLat-CS202.
A study to evaluate the long-term safety of GANFORT® (bimatoprost 0.03% plus timolol 0.5%) in Chinese patients with open-angle glaucoma or ocular hypertension who are insufficiently responsive to topical beta-blocker or prostaglandin analogues.
Phase III trial involving topical application, in both eyes, of trabodenoson ophthalmic formulation 3.0% or 6.0% once per day or 4.5% twice per day, placebo twice per day, or timolol 0.5% twice per day for 12 weeks in adult subjects with Ocular Hypertension or Primary Open-Angle Glaucoma. All subjects who meet the study's enrollment criteria following Screening will undergo washout of all prohibited medications, including their routine glaucoma medications. During the Placebo Run-In Period, placebo is administered twice daily to both eyes in all subjects. During the Treatment Period, study drug is applied to both eyes for a total of 12 weeks followed by an Observation Period of approximately 7 days wherein no study eye drops are instilled. The purpose of the study is to assess the efficacy, tolerability, and safety of binocular topical application of trabodenoson ophthalmic formulation 3.0% or 6.0% QD or 4.5% BID for 12 weeks. Timolol is being included in the trial in order to have an active control to ensure the integrity of the trial from an efficacy perspective; the primary comparator for all statistical purposes is the placebo arm.
The purpose of this study is to compare the Technology-based Eye Care Services (TECS) protocol to the standard face to face ophthalmologic exam.
To evaluate ocular hypotensive efficacy and safety of PG324 Ophthalmic Solution compared to Netarsudil (AR-13324) Ophthalmic Solution and Latanoprost Ophthalmic Solution. Following completion of the Month 12 study visit procedures, subjects will be offered the opportunity to participate in a 2-month observational (i.e., non-interventional) trial extension.
To evaluate ocular hypotensive efficacy and safety of Netarsudil (AR-13324) Ophthalmic Solution compared to Timolol Maleate Ophthalmic Solution.
Glaucoma is one of the leading causes for blindness in industrialized countries. It is characterized by a progressive loss of retinal ganglion cells, morphological changes in the optic nerve head and a characteristic loss of visual field. It has been speculated for a long time that vascular factors may also contribute to the pathogenesis of the disease. This concept has been supported by several epidemiological studies showing that small retinal vessel calibre are associated with the disease. In the recent years tremendous enhancements in the field of optical coherence tomography has been achieved. These developments made it possible to visualize the retinal vasculature in a full depth manner without the application of an intravenous marker. The proposed study tests the hypothesis that patients with glaucoma show altered vascular morphology compared to healthy subjects. This is of importance because it may clarify the degree of vascular involvement in glaucoma.
Glaucoma is the leading cause of irreversible blindness worldwide. This study aims to test a new method that may allow earlier diagnosis of glaucoma and better ways to monitor if it is getting worse. There is scientific evidence that the macula, the central part of the retina, can be involved in very early stages of glaucoma. Glaucomatous damage to the macula is very prevalent and is often missed using conventional clinical tests. Relatively little is known about progression of early glaucoma damage and its effects on the macula. This project investigates the nature of progressive damage to the macula and proposes new methods to improve accuracy to detect clinically significant progression.The study will evaluate the nature of damage to the macula's structures through OCT imaging and eye function via visual field tests.
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).
Lowering intraocular pressure remains the mainstay of therapy in the management of glaucoma. The effect of ocular massage on intraocular pressure in patients with acute primary angle closure was the important thing.This was a prospective study, in which 20 eyes from 20 patients had acute angle closure. When they went to the hospital, ocular massage was performed without any medication. Intraocular pressure was detected by Goldmann tonometer, and Lenstar LS900 optical biometry observed changes of anterior chamber depth before and after ocular massage. Anterior chamber depth, anterior chamber angle and ciliary body were observed by Ultrasound biomicroscopy after massage, and anterior chamber angle was also checked by gonioscope after massage.
