Filter by:The purpose of this study is to demonstrate superior intraocular pressure (IOP) control with travoprost 0.004% / timolol 0.5% (DuoTrav®) compared to beta-blocker monotherapy in patients with open-angle glaucoma or ocular hypertension.
The study will evaluate patients diagnosed with POAG or OHT who are switched to GANFORT® UD (unit dose of fixed combination bimatoprost and timolol) therapy for medical reasons in accordance with physician standard clinical practice. All treatment decisions lie with the physician.
Glaucoma is a progressive disease resulting in loss of retinal nerve cells and their axons (retinal nerve fibers). Retinal nerve fibers are ordered in a special manner when they enter the optic nerve. Hence, damage to the retinal nerve fibers by glaucoma results in visual field defects at certain locations. Furthermore, the retinal nerve fiber layers from different receptors for different colors are ordered in a special manner as well. Thus, it is possible that glaucomatous damage causes color vision dysfunction (dyschromatopsia). At the moment there is disagreement whether dyschromatopsia occurs at early- to mid-stage or only in end-stage glaucoma. By testing color vision in glaucoma patients the prevalence of dyschromatopsia in glaucoma and in different stages of the disease will be investigated.
This study is a Post-Marketing Surveillance study in Korea to evaluate the safety and efficacy of Combigan® (brimonidine tartrate/timolol maleate) Ophthalmic Solution in patients with Open Angle Glaucoma or Ocular hypertension with insufficient response to local beta blockers treated as per standard of care in clinical practice.
This is a prospective, open label study assessing the 24-hour IOP patterns using TF in patients undergoing anti-VEGF injection for the treatment of neovascular AMD (age related macular degeneration). The study will be proposed to patients with AMD and patients with AMD and concomitant open angle glaucoma (OAG). The study will be conducted in two stages. In both stages, patients will remain ambulatory and will be encouraged to follow a schedule as close to their usual lifestyle as possible, with the exception of particular activities such as caffeine intake, playing wind instruments, yoga and strenuous exercise. A patient diary will be distributed for the capture of patient activities during the TF pattern recording. Upon completion of each session, the CLS (contact lens sensor) will be removed and a final ophthalmic examination will be conducted. In the first stage of the study, 20 patients with neovascular AMD with an IOP in the normal range and no concomitant glaucoma will be recruited. After having signed and dated the patient informed consent form, patients will undergo an initial ophthalmic examination. One eye will be selected for the study. If both eyes are eligible, the study eye will be selected in random manner. All 20 AMD patients will receive two 24-hour recording sessions (S) with the TF CLS, at monthly interval. In the first session (S1) anti-VEGF injection will be carried out according to the study center standard protocol. For the second 24-hour TF recording session (S2), patients will be randomly distributed into three groups. Group A, consisting of 5 patients, will receive anti-VEGF injection with a different anti-VEGF substance as compared to S1. Group B, also consisting of 5 patients, will receive anti-VEGF without sclerotomy occlusion after injection as compared to S1. Finally, group C, including 10 patients, will receive anti-VEGF in a different dose (injection volume) as compared to S1. The randomization ratio between groups A, B and C is 1:1:2. The overall study duration for an eligible patient in the first stage of this study is limited to 5 weeks. If in the first stage of this study an injection protocol is identified that provokes significantly lesser elevation on the TF pattern, the alternative injection protocol will be evaluated against the current standard protocol. For the second stage, 30 patients of whom 15 with neovascular AMD and 15 with neovascular AMD and concomitant OAG will be recruited. After giving informed consent and confirmation of eligibility, all patients will receive two 24-hour TF CLS recording sessions (S3 and S4) at monthly interval, during which anti-VEGF injection according to the standard and alternative protocol will be carried out in random sequence. The overall study duration for a patient in the second stage of the study is limited to 5 weeks. The study has been planned to recruit 20 eligible patients in the first stage within 12 weeks from the date of initiation. The second stage will recruit 30 patients within 16 weeks. Hence the overall study duration from the first patient accrued into the study until last patient out equates to about 33 weeks. Allowing for a database lock within 4 weeks of study completion, a preliminary statistical report on the primary efficacy endpoint is foreseen within 2 weeks thereafter.
Increased intraocular pressure (IOP) has been identified as the most important risk factor for the development and the progression of glaucoma. Data from large interventional studies have shown that a decrease of IOP is associated with a reduced risk of progression of the disease. This underlines the importance of a potent and save IOP lowering therapy. The introduction of preservative free tafluprost offers a new treatment possibility using a potent topical prostaglandin analogue without the disadvantages of a co-administered preservative. The current study seeks to investigate the effect of an 8 week therapy with preservative free tafluprost on intraocular pressure in patients with ocular hypertension or primary open angle glaucoma having an IOP of 30 mmHg or more.
The purpose of this study is to evaluate intraocular pressure (IOP) over a 24-hour period using Simbrinza™ topical ophthalmic suspension.
This study is a Post-Marketing Surveillance study to evaluate the safety and efficacy of bimatoprost/timolol (Ganfort®) Ophthalmic Solution to treat open-angle glaucoma or ocular hypertension in Korea.
The purpose of this study is to evaluate the effectiveness of a new laser (called Micropulse Laser Trabeculoplasty or MLT) in the treatment of glaucoma compared to the conventional laser presently used which is called selective laser trabeculoplasty or SLT. Both lasers (SLT and MLT) are used as standard of care in the treatment of open angle glaucoma.
The objective of this Phase 1 study is to evaluate the VISION5 Product's safety and efficacy.
