Filter by:A prospective, multicenter, open-label, safety and preliminary efficacy study of the surgical implantation of OPKO's glaucoma drainage device (AquashuntTM) in patients with refractory chronic forms of open angle glaucoma (OAG). The primary objective of this study is to evaluate the surgical implantation, safety and preliminary efficacy of the AquashuntTM after implantation in patients with refractory chronic forms of OAG
This research is being done to determine if closing your eyelids after you take your glaucoma drops makes them more effective in lowering your eye pressure, and to determine if closing your eyelids for 5 minutes is better than closing them for one minute
A study to evaluate the effect of the 12-week treatment with timolol/dorzolamide combination eyedrops (COSOPT) on decrease in intraocular pressure (IOP) at 2 hours after the study drug administration
To investigate of high cup/disc ratio in children.
To study the effect of Diclofenac drops or Dexamethasone drops on combined surgery of trabeculectomy and cataract surgery.
We have completed a study in which we examined the response of the retinal circulation to changes in posture from sitting to lying down in patients with primary open angle glaucoma (POAG). This alteration in position produces changes in the local blood pressure at the entrance to the retinal vasculature. In a healthy retina, the vasculature adapts by dilating and constricting in order to maintain a steady blood flow rate. In an eye with POAG, this often does not occur. As a result, there are large fluctuations in blood flow which may produce the retinal neuronal damage associated with glaucoma. The purpose of this study is to demonstrate that topical anti-glaucoma treatments with agents that have vasoactive as well as IOP-lowering effects can have a beneficial effect on maintaining a steady retinal blood flow rate even when there are changes in local blood pressure.
The purpose of this study is to evaluate the ocular safety and efficacy of a glaucoma drug delivery system in open-angle glaucoma or ocular hypertension.
The objective of the study was to evaluate whether timolol hemihydrate is more comfortable upon instillation than timolol maleate in sorbate. This was an observational study. Subjects with open-angle glaucoma or ocular hypertension were asked to complete a survey regarding their normal treatment. No treatment was prescribed.
This study compares the efficacy and tolerability/comfort of brimonidine/timolol and dorzolamide/timolol in patients with open-angle glaucoma or ocular hypertension. In an investigator masked randomization process, each subject is allocated to recieve either brimonidine/timolol or dorzolamide/timolol as fixed-combination monotherapy or as an adjuctive to a prostoglandin analogue for a period of 12 weeks. After screening, patient returns at baseline, Month 1, and Month 3 for ophthalmic evaluations.

In an investigator masked randomisation process, each subject is allocated to received either brimonidine/timolol or dorzolamide/timolol as fixed-combination monotherapy or as an adjunctive to a prostaglandin analogue for a period of 12 weeks. After screening, patient returns at baseline, Month 1 and Month 3 for ophthalmic evaluations.
