Filter by:Screening of haitian children between the ages of 3 and 6 years old for amblyogenic risk factors with the use of the Spot photoscreener. The photoscreener results will be compared to the complete ophthalmologic evaluation. Primarily, this will allow evaluation of the performance of the spot photoscreener in the haitian children population. Secondarily, this study will gather epidemiological information on vision problems in the haitian children population.
This triple-blind, stratified, randomized clinical trial includes 100 eyes of 100 patients aged 18 to 85 years with refractory glaucoma. Eligible subjects undergo stratified block randomization; eyes are first stratified to one of four subgroups: group 1:patients with previous failed trabeculectomy, group 2: uveitic glaucoma, group 3: neovascular glaucoma and group 4: other indications like aphakic glaucoma or glaucoma associated with vitreoretinal procedures. In each subgroup, eyes are randomly assigned to the study arms using random blocks: conventional Ahmed Glaucoma Valve (AGV) implantation (group A, 50 eyes), Ahmed Glaucoma Valve (AGV) with intraoperative periplate triamcinolone injection (group B, 50 eyes). Patients will be followed for one year. They will undergo full ophthalmology examination at first day, first week, month 1, 3, 6, 9 and 12 after the surgery. The primary outcome measure is cumulative probability of success, defined as intraocular pressure (IOP) of 6-21 mm Hg, with or without medication, and no serious complications, additional glaucoma surgery, or loss of light perception. The outcomes will be compared between two arms in each subgroup. The number of eyes requiring medications, time to initiation of medications, and number of medications will be compared.
To determine the efficacy of intravitreal ranibizumab injection as adjuvant therapy in the treatment of postvitrectomy diabetic vitreous hemorrhage (PDVH) accompanied by neovascular glaucoma (NVG) as a means of preventing recurrent vitreous hemorrhage （VH） and optimizing postoperative intraocular pressure（IOP）control.
Prospective randomized trial in patients requiring cataract surgery in which IOP, angle anatomy and other demographic and clinical data are compared. Subjects randomized to both MSICS and phakoemulsification
Aflibercept (Eylea®) and ranibizumab (Lucentis®) are an anti-VEGF, but there are differences between the two drugs. To determine and compare whether intraocular aflibercept and ranibizumab decreases rubeosis iridis (RI) in patients with neovascular glaucoma (NVG).
The proposed trial a "Randomized, Double Blind, Placebo Controlled "first in-human" Study to Assess the Safety and Tolerability of Single Ascending Oral Doses of PBF-677 in Male Healthy Volunteers" (Protocol Code No:CUNFI-1509 EudraCT No:2015-003546-57) will be a single-centre, randomized, double-blind, dose escalation study without therapeutic benefit, in which PBF-677 will be administered as single, oral, ascending-dose to volunteers. Up to four different rising doses (100 mg, 200 mg, 400 mg and 600 mg) will be tested in groups of 8 participants; in each dose level participants will be randomized to active drug or placebo in a 6:2 fashion. As this will be the first time that PBF-677 in going to be administered to humans, as a safety measure a stepwise drug administration will be performed in each cohort. The volunteers of each cohort will be divided in 3 blocks/subgroups: Initially, one volunteer will receive active drug (subgroup 1). After 48h of safety and tolerability assessment, a second subgroup of 3 volunteers will receive 2 active drug and 1 placebo and after further 48h of safety and tolerability assessments a third subgroup of 4 volunteers will receive 3 active drug and 1 placebo. After evaluation of safety, parameters of corresponding dose level the process will replicate one week afterwards in the following dosages. The principal variable safety and tolerability of PBF-677 will be evaluated with physical records (Electrocardiogram (ECG), vital signs, blood chemistry and haematology, conducted before, during and after study course). Assessment of the pharmacokinetic profile (Maximum plasma concentration of the drug (peak) after single dose (Cmax),Time necessary to reach Cmax (tmax), Area under the time-concentration curve to "zero" to time "t" (AUC0t), and Elimination half-life (t1/2) of PBF-677 will be included as secondary variable.
The purpose of this study is to determine if an eye drop video monitoring device can accurately assess (as compared to a patient's own log or a proprietary software) the exact amount and time of eye drop delivery to a patient's eye. It is our belief that the experimental device will help patients to be more compliant by: 1) providing a viewable format so patients can see what is happening when they are applying their drops 2) providing greater accuracy to doctors regarding when and how much medication was used 3) providing greater accuracy to doctors and patients regarding how much medication was actually delivered to a patients eye.
This study was to assess the distinct expression of matrix metalloproteinase 13,tissue inhibitor of metalloproteinases 3, and calcium-sensing receptor, in human trabecular meshwork between normal and glaucomatous eyes.The expressions of matrix metalloproteinase 13, tissue inhibitor of metalloproteinases 3 and calcium-sensing receptor in the trabecular meshwork tissues were examined by streptavidin-peroxidase immunohistochemical staining method and western blot, and histological changes of trabecular meshwork were studied by Hematoxylin and Eosin staining.
This study will evaluate the intraocular pressure (IOP)-lowering effect and safety of Bimatoprost SR compared with selective laser trabeculoplasty in participants with open-angle glaucoma or ocular hypertension who are not adequately managed with topical IOP-lowering medication for reasons other than medication efficacy (e.g., due to intolerance or nonadherence).
1. Investigate degree of postoperative satisfaction in county level hospital glaucoma patients. 2. Investigate the effect of educational intervention affect the degree of satisfaction in glaucoma patients. 3. Investigate the effect factors of postoperative satisfaction.
