Filter by: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 study is a double-masked, randomized, parallel group study in patients with open angle glaucoma or ocular hypertension. The aim of this study is to verify the efficacy of the fixed combination of Latanoprost 50 mcg / mL / brinzolamide 10mg/ml eye drops compared to Latanoprost 50μg/mL eye drops in reducing IOP
This is a prospective, observational, single-center study. Patients with at least 3 months of experience using topical medications for glaucoma and who state that they administer their own eye drops will be recruited. Subjects will be videotaped instilling a sterile artificial eye drop, will be identified at the time of a regularly scheduled exam. If the patient can get a drop onto the eye and also not touch their lids or ocular surface with the eye drop bottle, the subject will be thanked but not enrolled. All other patients who agree to participate will be enrolled. Upon completion of videotaped instillation of an eye drop, each enrolled patient will be shown a video demonstrating an instillation technique and will be given an instructional handout highlighting a proper drop instillation technique. If necessary, an instillation technique will be demonstrated to them by an investigator or trained personnel. A patient will be identified as properly instilling a drop if they satisfy the following criteia: They are able to instill one (and only one) drop to the ocular surface or lower fornix without allowing the bottle touch the adnexa, eyelid, eye lashes or eye. All patients routinely return between 3 and 6 months. At this regularly scheduled visit,the investigator or trained personnel would direct the patient to instill an eye drop into the study eye.Additionally, the short glaucoma self-efficacy questionnaire will be re-administered. All of the video-recordings of participants' eye drop instillation techniques will be reviewed and assessed using a standard checklist. Their ability to administer an eye drop after training will be compared to baseline.
- To assess the safety and tolerability of repeat dose topical administration of MRZ-99030 Ophthalmic Solution with ascending doses in healthy subjects (stage 1) and glaucoma subjects (stage 2). - To assess plasma pharmacokinetics and urine concentration of MRZ- 99030 and its metabolite MRZ-9499 after single and repeat dose topical administration of MRZ-99030 Ophthalmic Solution.
This 52 week study will assess the use of intravitreal aflibercept injections in patients with neovascular glaucoma (NVG) compared to standard of care panretinal photocoagulation. The investigators hypothesize that the neovascularization of the iris and angle present in neovascular glaucoma will resolve more quickly in eye treated with intravitreal aflibercept injection alone and result in increased comfort and preservation of visual field as compared to current standard of care utilizing pan-retinal photocoagulation. The advantages to intravitreal aflibercept injection use could include resolution of NVI/NVA (neovascularization of the iris/neovascularization of the angle) leading to quicker pain relief and quicker lowering of IOP (intraocular pressure).
The aim of this project: 1. Confirming the modification in corneal astigmatism after trabeculectomy with MMC and intracameral administration of bevacizumab. 2. Medium-term follow up (6 months) of the induced corneal astigmatism. 3. Investigating correlations between postoperative astigmatism, particularly with the postoperative IOP.
Glaucoma is the second leading cause of blindness among seniors in Canada. It is often associated with an elevated intraocular pressure (IOP), but its exact mechanism is still largely unknown. Some studies have shown a link between glaucoma and changes in the amount of oxygen in the veins of the eye. The study aims to compare the amount of oxygen in ocular veins among three different groups using a spectrophotometer. This instrument is linked to a camera and can measure the quantity of oxygen in the veins using different characteristics of the blood inside. The groups of the study are: patients without glaucoma, patients suspected of glaucoma and patients newly diagnosed with glaucoma. The drug the investigators are using, Travoprost 0.004%, will only be administered to the groups suspected or diagnosed with glaucoma. Travoprost 0.004% is already approved for use in Quebec and is part of standard care. Ten patients will be recruited into each group for a total of 30 patients in this study. All patients for the suspected or diagnosed groups will be recruited from the Jewish General Hospital. Subsequently all testing will be done at the École d'optométrie, Université de Montréal
Glaucoma is one of the leading causes of blindness in the west. The disease caused by high intra ocular pressure (IOP) and characterized by damage to the optic nerve and gradual loss of visual field. Intra ocular pressure change during the day. To evaluate the efficiency of the therapy it is common to measure the intra ocular pressure at different times of the day. Most ophthalmologists admit the patient for one day at which intra ocular pressure is measured at different times. This method does not mimic the patient daily routine and may not reflect the true diurnal fluctuations. For this reason some ophthalmologists measure the intra ocular pressure at different times and at different days. It is not known if both methods give similar diurnal curves.
This clinical investigation is being performed to compare the effect of BOL-303259-X dosed once daily (QD) with timolol maleate 0.5% dosed twice daily (BID) in reducing intraocular pressure (IOP) measured over a 24-hour period in subjects with open-angle glaucoma (OAG) or ocular hypertension (OHT).
A number of large clinical trials have found pseudoexfoliation (PXF) to be a major risk factor for glaucoma progression and risk of blindness. It is estimated that PXF accounts for approximately a quarter of cases of open angle glaucoma in Nova Scotia, Canada, making this region an ideal setting for studying patients with this condition. Despite associated high morbidity, the treatment of pseudoexfoliative glaucoma remains suboptimal and a challenge for the clinician. Topical medical therapy is less effective than for primary open angle glaucoma and patients often require early surgical therapy, with associated risks. Selective laser trabeculoplasty (SLT) may be a safe and effective treatment for pseudoexfoliative glaucoma, although the evidence for this is presently lacking. The aim of the current study is to provide the first controlled-trial evidence for the effectiveness of SLT, compared to topical therapy, in the management of pseudoexfoliative glaucoma.
