Filter by:The purpose of this study was to compare the safety and intraocular pressure (IOP)-lowering efficacy of a new fixed combination of brinzolamide/brimonidine (Brinz/Brim) to: - its individual components (Brinz and Brim), and - the concomitant administration of Brinz and Brim (Brinz+Brim).
To demonstrate superiority of DuoTrav APS over XALACOM® in Ocular Surface Health in patients with open angle glaucoma or ocular hypertension.
The purpose of this study is to compare the efficacy and safety of Trabectome versus Trabeculectomy with adjunctive Mitomycin C, combined with cataract surgery, in patients with open angle glaucoma.
A variety of studies demonstrate that ocular blood flow is altered in glaucoma. Various animal and human studies have shown an increase in retinal and optic nerve head blood flow in response to diffuse luminance flicker. Based on studies with ERG, this effect has been attributed to augmented activity in the retinal ganglion cells and associated axons indicating a coupling mechanism between neuronal activity and retinal blood flow. Whereas a variety of studies have confirmed these effects, the knowledge about this coupling in the retina of patients with glaucoma is sparse. Recently the investigators could show that flicker induced vasodilatation is blunted in patients with open angle glaucoma. However, the investigators results are limited by the fact that only data about retinal vessel diameters, not blood flow per se, are available. The further development of the investigators current flicker stimulation technique now allows us to determine blood flow velocity during flicker stimulation. Thus, in the current study, the investigators set out to determine whether this blood flow response is impaired in patients with glaucoma as compared to those in healthy volunteers and whether this is related to altered neural activity. The study objective was, to investigate whether the blood flow response to flicker stimulation is altered in patients with glaucoma.
Argon laser trabeculoplasty (ALT) with 100 ms pulses is an effective therapy for lowering intraocular pressure (IOP). Similar reductions in IOP have been achieved using ns (SLT) and microsecond (MLT) pulses, which produce less thermal damage to trabecular meshwork (TM). Lack of clinically visible changes may make the accurate alignment of subsequent pulses difficult. We describe a novel technique - Patterned Laser Trabeculoplasty (PLT) using the PASCAL Photocoagulator system, and its preliminary evaluation in patients with open angle glaucoma.
The purpose of this study was to assess the effects of total volume and total dose on the safety and intraocular pressure-lowering efficacy of Anecortave Acetate Suspension (3 mg and 48 mg) in 0.5 mL and 0.8 mL volumes when administered by anterior juxtascleral depot (AJD) for the treatment of elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension.
To compare the efficacy and safety in patients treated with travoprost versus dorzolamide/timolol maleate combination in patients with open-angle glaucoma or ocular hypertension
Selective laser trabeculoplasty (SLT) is a new alternative to anti-glaucoma medications for the treatment of primary open angle glaucoma. After SLT, many patients experience mild to moderate inflammation inside the eye - specifically in the front chamber of the eye (the part in front of the colored part of the eye). This mild front chamber reaction is typically treated with anti-inflammatory agents such as corticosteroids and nonsteroidal anti-inflammatory agents (NSAIDs). Some physicians do not use these agents as they feel they may interfere with the way the laser works to treat glaucoma. Topical (applied to the surface) corticosteroids can cause an increase in the pressure of the eye (intraocular pressure or IOP), cataract formation, or a possible increase in infection with long-term use. These side effects have not been reported to occur with NSAIDs, which are effective in controlling pain after SLT and reducing signs of inflammation such as irritation, swelling, tenderness, and soreness. This research study will compare an NSAID, ketorolac tromethamine 0.4% (Acular LS), with a corticosteroid, prednisolone acetate 1% (Pred Forte), and with a placebo, which contains no active medicine (Refresh Tears). Ketorolac tromethamine 0.4%, prednisolone acetate 1%, and Refresh Tears are all FDA (Food and Drug Administration) approved for use in inflammation after surgery.
The purpose of the study is to determine whether combined cataract and glaucoma surgery (phacotrabeculotomy)is more effective in lowering intraocular pressure than cataract surgery alone in patients with borderline control of intraocular pressure.
The purpose of this study is to evaluate safety and efficacy of two different IOP lowering medications after six weeks of treatment in Caucasian and Japanese subjects.
