Filter by:The purpose of this study is to determine the effect of artificial tears preserved with Benzalkonium Chloride (AT-BAK) on the IOP response to the L-PPDS and to evaluate the safety of the L-PPDS in subjects with OH or OAG following treatment.
Laser Trabeculoplasty has been shown to be effective in lowering intraocular pressure (IOP) in patients with primary open-angle glaucoma (POAG). Although initially demonstrated with the Argon laser (ALT), several other laser systems have also been employed with comparable efficacy. Recently, Selective Laser Trabeculoplasty (SLT) has been shown to lower intraocular pressure comparable to ALT. The advantage of SLT is that the target eye structure, the trabecular meshwork, remains intact with minimal damage at the cellular level. In contrast, ALT lowers IOP at the expense of scarring of the trabecular meshwork. The purpose of this study is to evaluate the efficacy of lowering IOP with Pascal Laser Trabeculoplasty (PLT) employing reduced energy levels compared to ALT and a computer guided pattern of laser treatment applications.
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.
