Filter by:This study is evaluating possible non-intraocular pressure (IOP) related effects of the alpha-1 agonist brimonidine in human subjects affected by a progressive glaucomatous optic neuropathy. Brimonidine was proven as neuroprotective in several pre-clinical animal studies.
The purpose of this study is to assess patient compliance with DuoTrav versus concomitant administration of Timolol 0.5% plus TRAVATAN in patients with open-angle glaucoma or ocular hypertension.
The purpose of thie study is to compare the safety and IOP-lowering efficacy of AL-37807 Ophthalmic Solution 0.05%, 0.1% and 0.2% dosed QD AM to Xalatan dosed QD PM and Vehicle in patients with open-angle glaucoma or ocular hypertension
To quantify oxidative stress in circulating leukocytes of normal tension glaucoma patients, prior to and one month after routine vascular therapy.
Glaucoma is a leading cause of blindness worldwide. Non-adherence to glaucoma medication, which may result in loss of vision, is known to be prevalent. Available information regarding adherence to prescribed medical therapy suggests that some apparent treatment failures may actually be due to non-adherence. The investigators' specific aim is to conduct a study that will examine the effect of a glaucoma educator intervention on adherence to topical glaucoma therapy. The investigators' hypothesis is that patient education and counseling delivered by a trained glaucoma educator, through both planned visits and telephone contacts, will increase adherence to topical glaucoma therapy.
Elevated intraocular pressure is widely accepted as a risk factor for glaucoma and controlling the pressure remains the cornerstone of effective treatment. There is evidence that posture can have a significant effect on intraocular pressure fluctuations. Salat (or Salah) refers to the five daily prayers performed by Muslims. The time spent praying in a kneeling or prostrate position may be associated with wide fluctuations in intraocular pressure, potentially sight-threatening for Muslim patients with glaucoma. The researchers seek to investigate the link between traditional daily Muslim prayer postural changes and intraocular pressure changes.
When implanting an Ahmed glaucoma tube, a scleral flap is usually created to cover the tube, and the conjunctiva is stitched back in place with nylon 10-0 sutures. It is hypothesized that an equally safe or better method is using a bovine pericardial patch graft that can be secured in place over the tube with tissue glue, and using tissue glue to reposition the conjunctiva in place.
Sequential Laser Iridotomy uses argon and Nd:yag laser in the first and second steps, respectively. Using q-switched 532 nm laser in the second step is hypothesized to be as good and effective as the conventional Nd:yag laser, because it selectively targets pigmented cells and delivers a short pulse duration of 3 nanoseconds, causing less thermal and collateral damage.
There is growing evidence that a cause of glaucoma is linked to circulatory problems and poor auto-regulation of blood flow to the optic nerve. Pulmonary hypertension (PH)is a disease characterized by low oxygen levels in the blood and altered blood circulation. The decrease in oxygen delivery to the optic nerve could lead to the loss of nerve fiber layer(NFL)in the retina and the resulting visual field compromise. This situation is characteristic of glaucoma. The ability to identify NFL thinning early could lead to earlier diagnosis of glaucoma and more effective treatment to limit dysfunction from visual field loss. We hypothesize that the rate of structural damage to the NFL, a feature of glaucoma, is higher in patients with PH than expected in healthy populations lacking this disease.
The purpose of this study was to evaluate the safety and intraocular pressure (IOP)-lowering efficacy of anecortave acetate for treatment of elevated IOP in patients with open-angle glaucoma.
