Active clinical trials for "Ocular Hypertension"

The purpose of this research study is to determine the diurnal and nocturnal effects of Travoprost with SofZia (Travatan Z) on intraocular pressure and ocular perfusion pressure.

The main purpose of this prospective study is to demonstrate the therapeutic equivalence of topical brinzolamide dosed three times daily compared with AzoptTM (brinzolamide ophthalmic suspension 1%) dosed three times daily in IOP reduction in patients with POAG or OH.

This is an observational study of Lumigan® 0.01% (bimatoprost) treatment in clinical practice for patients with Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT).

A soft contact lens integrating a Sensor is placed on subjects with high intraocular pressure (IOP) after administration of an IOP-lowering drug to investigate the device's capacity to detect the induced IOP reduction.

The purpose of this study is to measure pressures within the eye (during surgery to remove the prostate or abdominopelvic masses) as the body position required for these laparoscopic procedures has been associated with increases in pressure within the eye.

Bimatoprost has been shown to provide effective IOP lowering in patients of all races. Conversely, travoprost has been shown to be more effective in black patients than in Caucasians in some studies. However, Noecker et al 2004 compared bimatoprost with travoprost in African-Americans with glaucoma or OHT, and found that bimatoprost was more likely than travoprost to achieve target pressure at 3 months. These racial differences in efficacy of these medications warrant further investigations. The investigators study aim to compare the IOP-lowering efficacies of bimatoprost and travoprost in an Egyptian population with primary open-angle glaucoma (OAG) or ocular hypertension (OHT).

Intravitreal triamcinolone acetonide (IVTA) is a commonly employed treatment for various vitreoretinal disorders. However, approximately 23% to 50% of patients who receive IVTA develop ocular hypertension after the drug is injected into the eye. Similar to IVTA, topically administered corticosteroids eye drops result in ocular hypertension in approximately 33% of the population. It is unknown whether identifying patients who develop ocular hypertension from topical corticosteroids could be used to identify patients who are at risk for injectable IVTA. Therefore, the purpose of this study is to evaluate the efficacy of topical prednisolone 1% four times daily for one month as a screening test to reduce the incidence and severity of ocular hypertension after IVTA injection.

Although Benzalkonium chloride (BAC) has been used as a preservative for many years, many studies have demonstrated that prolonged use of topical ocular medications preserved with BAC may exacerbate sequelae associated with ocular surface disease. These effects could lead to the induction of subclinical inflammation,1 reduction of corneal epithelial barrier function, 2, 3 destabilization of the tear film, 4 cataract formation, 5 and an overall higher incidence of patient complaints of dryness and irritation. 4-6 This study will compare the efficacy of travoprost 0.004% without benzalkonium chloride (BAC) to that of the marketed formulation of latanoprost 0.005%with BAC in patients with dryness and irritation and open-angle glaucoma or ocular hypertension. A double blind comparison will be used to assess whether those two different formulations will affect the tear breakup times, corneal staining, and baseline tear secretion tests in patients that are already taking latanoprost regularly with complaints of dryness and irritation. Patients included in the study will be given two bottles, one labeled for their right eye and the other for their left eye. Each pair of bottles will be identical in appearance and randomized with either latanoprost or travoprost and each pair will be assigned a number to aid in future analysis of the final results.

This single-center, investigator-masked, crossover study is designed to investigate the circadian rhythms of aqueous humor dynamics in human subjects with ocular hypertension (OHT) before and after intervention with a commonly used ocular hypotensive medication, brimonidine.

Evaluate the incidence of hyperemia in patients using bimatoprost and to determine if simple interventions reduce its incidence and to assess the value of detailed instruction in increasing patient compliance and willingness to continue bimatoprost therapy, despite the occurrence of hyperemia.
