Filter by:This study will evaluate the effect of the timing of treatment completion in two-staged selective laser trabeculoplasty therapy on intraocular pressure lowering effect.
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
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.
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 this study is to determine whether the OculusGen Collagen Matrix are effective and safe to implant as an aid of glaucoma surgery.
Purpose: To evaluate the influence of the nonsteroidal anti-inflammatory indomethacin on the brimonidine intraocular pressure (IOP) lowering effect. Methods: A randomized double-masked study was carried out. Patients medicated with timolol maleate 0,5% and needed complementary medication were random allocated into two groups: (a) brimonidine tartarate 0,15% and indomethacin 1% or (b) brimonidine tartarate and placebo (balanced saline solution). If patient’s both eyes were eligible, they were allocated to the same group. IOP was measured at two weeks, one month and two months after study beginning. The mean IOP of the eyes was used for analyzes, in the case of two eligible eyes. For statistical analyzes repeated measures analysis was used.
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 aim of the study is to determine if plasma matrix-metalloproteinase activity can predict glaucoma in patients with OSAS and if the level of plasma matrix-metalloproteinase activity will decrease after one month of nCPAP-treatment.
Glaucoma is the leading cause of irreversible blindness in the world, resulting from progressive axonal destruction of the optic nerve. Primary open-angle glaucoma is the most common form, and it is usually painless with insidious onset. Conventional treatment is focused on lowering intraocular pressure (IOP), the one risk factor that can be modified, which has been demonstrated to protect against further damage to the optic-nerve head. Acupuncture is an ancient treatment which has been found to be beneficial for many ailments, and may reduce IOP. We propose a pilot study to evaluate whether acupuncture is an effective and safe modality for reducing elevated IOP in patients with open angle glaucoma and primary ocular hypertension. Patients with elevated IOP on tonometric measurement (20mmHg < IOP < 30mmHg) will be treated twice-weekly with a standardized (as opposed to individualized) acupuncture treatment. Treatment will last for four-weeks (for a total of 8 treatments), and patients will be evaluated for IOP diurnal curves at 2 weeks (4 treatment), 4 weeks (end of treatment ) and then 4 weeks following the last treatment.
Glaucoma is a disease which affects between one and two percent of all individuals aged over 40 years. According to recent Canadian National Institute for the Blind figures, it is the second largest specific cause of blindness in this country. The most common form of glaucoma, open-angle glaucoma, is incipient and typically results in a progressive loss of vision without symptoms due to damage to a structure inside the eye called the optic nerve head. Although the most important known risk factor for the development of open-angle glaucoma is high intraocular pressure (the pressure within the eyeball), a number of researchers have shown that a sizeable proportion of patients continue to lose vision in spite of successful treatment to lower their intraocular pressure. This finding suggests that there may be additional risk factors involved. Ocular vasospasm (the inability of certain blood vessels to dilate and increase blood flow according to the needs the eye) and vascular disease are among other factors implicated but their roles have not yet been fully investigated. The Canadian Glaucoma Study Group proposes to investigate the role of risk factors, including vasospasm and vascular disease, involved in the progression of open-angle glaucoma. We will recruit 410 patients with open-angle glaucoma across 4 centres (Halifax, Vancouver, Montreal and Toronto) who will be treated by experienced investigative ophthalmologists according to a uniform standard protocol to ensure that all patients are managed in the same manner. The patients will be followed meticulously with the most modern and accurate tests available every four months for a period of 5 years to determine whether progression has taken place. Visual function will be measured using two techniques called conventional perimetry and blue-on-yellow perimetry, and optic nerve heads will be examined with a special scanner capable of three-dimensional imaging. By defining both the ocular and systemic profiles of patients who progress and do not progress, we may be able to identify which patients will benefit from the standard treatment of intraocular pressure reduction, such as that prescribed in the study. More importantly, we will identify the characteristics of patients who do not benefit from standard treatment, so that alternative ones may be developed. Such studies are clearly necessary, but have not yet been conducted. We believe that the proposed study will increase our knowledge of open-angle glaucoma and reduce its impact on blindness and visual disability.
