10 Clinical Trials for Various Conditions
To evaluate the influence of superior versus temporal laser peripheral iridotomy location on post-operative visual acuity and contrast sensitivity.
This study will assess any side effects that may occur when QPI-1007 is injected into the eye in subjects with acute primary angle-closure glaucoma, as well as how long it takes for the body to clear the drug. This study will also test whether QPI-1007, injected into the eye, helps prevent both structural damage of the nerve tissue in the eye and the loss of visual function in subjects with acute primary angle-closure glaucoma.
To demonstrate that the intraocular pressure(IOP)-lowering efficacy of Travoprost (0.004%) is equal or better than that of Latanoprost 0.005% in patients with chronic angle-closure glaucoma.
To evaluate the ocular hypotensive efficacy of Rho kinase Inhibitor (AR-12286 0.5% and 0.7%) ophthalmic solutions in patients diagnosed with chronic angle-closure glaucoma treated for 6 months. Secondary Outcome Secondary objectives are: 1. To evaluate the early effect of Rho kinase Inhibitor (AR-12286) in reducing intraocular pressure (IOP). 2. To evaluate the long term effect of the drug on IOP. 3. To determine if AR-12286 can be used as directed therapy for CACG, reducing or eliminating the structural blockage of the trabecular meshwork that leads to development of elevated IOP.
The aim of this study is to analyze similarities and evaluate interchangeability of Visante and Cirrus OCT (optical coherent tomography)and to compare agreement between gonioscopy and the two systems for evaluation of anterior segment parameters.
Glaucoma is one of the leading causes of blindness in the world. The key to prevention of visual loss from glaucoma is early detection of the disease or its progression and timely treatment. The proposed study will investigate the role of various tests in improving detection of disease progression in advanced glaucoma. Evaluation of the peripheral field of vision (visual field examination) remains the current standard for detection of progression in glaucoma. However, there is a lot of variability or inconsistency in eyes with advanced glaucoma, which could make it difficult to detect worsening of glaucoma with visual fields. The optic nerve demonstrates significant damage in such eyes and hence oftentimes repeat imaging of the optic nerve head is not helpful for detection of change. Therefore, imaging of the central retina (the innermost sensitive tissue lining the inside of the eye), called macula, has been proposed to supplant imaging of the nerve in eyes with severe glaucoma. The macula aids in detailed central vision. Since the macular retinal neural cells are the last ones to be affected in glaucoma, measurement of macular retinal thickness could provide significant information with regard to the course of glaucoma. In the proposed study, glaucoma patients will be tested and followed with various measurements done with newer versions of optical coherence tomography (OCT) imaging and visual field machines. The patients will undergo repeat imaging and visual field testing every 6 months over the course of 5 years. Rates of change will be estimated. We will explore if changes in various outcome measures derived from imaging are correlated with the corresponding visual field changes in glaucoma, and whether the former can be used as an alternative method for detecting simultaneous or subsequent glaucoma progression. The hypothesis for this proposed research is that macular OCT parameters are valid structural measures that can be used especially in advanced disease to follow the course of glaucoma.
The investigators hypothesize that KeraSys is a safe as Tutoplast to cover the tube of the Molteno 3 glaucoma drainage device during surgery
The purpose of this study is to examine if there is a difference between glaucoma patients having background music and not having background music before visual field testing.
The investigators hypothesize that intracameral Triesence during glaucoma surgery will provide lower intraocular pressure through better control of ocular inflammation, thus leading to a more successful filtering procedure.
The purpose of this study is to determine if there is a difference in the ocular signs and symptoms of subjects' eyes using Xalatan® 0.005% versus Travatan Z® 0.004% based on the outcome of subject assessment and clinical assessment in patients with Ocular Hypertension or Glaucoma with mild to moderate dry eye at baseline in accordance with the Oxford Grading Scale.
