Filter by:Glaucoma is a progressive optical neuropathy, generally associated with ocular hypertension. The treatment aims to stabilize the visual field deficiencies by lowering the intraocular pressure. Due to the fluctuation of the visual field test and re-test measures, the European recommendations are to obtain 6 visual field tests in 2 years (or one every 4 months) in order to know if the pathology is progressing despite the current treatment (or if the treatment is necessary, in cases of intraocular hypertensions). The lack of ophthalmologists renders the monitoring of a beginning glaucoma, rarely compatible with the present recommendations. It is therefore crucial to evaluate new therapeutic alternatives, when faced to a decreasing medical demography and an increase the patient's needs. This study should allow to validate the possibility to delegate monitoring tasks to orthoptists during glaucoma surveillance. To organize the delegation of this surveillance to orthoptists would permit a better distribution of the ophthalmologist's activities.
Transscleral cyclophotocoagulation of the ciliary body is an effective technique to reduce intraocular pressure in case of glaucoma. Due to concerns over complications, the main indications for this second-line treatment are refractory glaucoma medication / surgery and low visual prognosis. The 2000 milliwatts (mW) for 2 seconds settings are used by the majority of researchers and clinicians according to the published literature. Some have proposed using 1250 mW for 4 seconds to improve the use of this medical procedure. The aim of this study is to determine how different parameters affect the efficacy of the treatment. This is a prospective double-blinded randomized controlled trial comparing two groups, the experimental group using 1250 mW for 4 seconds and the control group using 2000 mW for 2 seconds.
The study objective was to evaluate the intraocular pressure (IOP) lowering effect of two iStent devices in eyes of subjects with primary open-angle glaucoma, washed out of two anti-glaucoma medications (one a Prostaglandin) prior to stent implantation.
This study objective is to evaluate the intraocular pressure (IOP) lowering effect of two trabecular micro-bypass stents (iStent inject) in eyes of subjects with primary open-angle glaucoma on one topical hypotensive medication
The purpose of this study is to determine whether glaucoma drop aids will be cost-effective in delivery of ophthalmic medications by improving medication compliance, visual function, and even decreasing medication waste in the patient population at Boston Medical Center (BMC).
The objective of this study is to evaluate the long-term efficacy and safety of COMBIGAN® (brimonidine tartrate/timolol malate) in patients only using COMBIGAN® (brimonidine tartrate/timolol malate) and also in patients who require additional IOP lowering with LUMIGAN® (bimatoprost) 0.01%.
Globally primary open angle glaucoma (POAG) affects over 60 million people. The exact pathogenesis of POAG is poorly understood. A significant risk factor for glaucoma is advancing age. The rate of ageing is not the same in all age matched individuals. The concept of accelerated ageing suggests that the presence of a number of specific genetic, environmental or systemic risk factors may cumulate to accelerate the ageing process in some individuals and lead to the development of age-related disease. Understanding the factors that influence accelerated ageing is vital. Advanced glycation end products (AGEs) are a complex group of compounds that are naturally formed. They accumulate gradually with age in cells, tissues and blood vessels throughout the body where they adversely affect structure and function. Circulating AGE levels can be influenced by oxidative stress levels and dietary intake. Recent research has found that sustained exposure to high levels of circulating AGEs could be a major factor in the development of a number of chronic age-related degenerative disorders, including POAG. To date there have been few clinical studies that have been able to non-invasively explore the association between AGE levels and the development and progression of glaucomatous optic neuropathy (GON), or to explore the possible contribution that oxidative stress and dietary intake make to total tissue AGE levels in such patients. Furthermore little is understood about the relationship between AGE levels and retinal vascular function, a parameter known to be altered in GON that also could be influenced by AGE levels. The proposed study will aim to evaluate whether tissue-bound AGE levels are associated with parameters of retinal vascular function, oxidative stress, dietary intake and the presence of GON. Establishing this association could increase our understanding of the pathogenesis of GON and allow a new biomarker for accelerated ocular ageing to be realised
The primary objective of the study is to assess the safety and tolerability of a 180μg/ml TID dose regimen of recombinant human nerve growth factor (rhNGF) eye drop solution administered over 8 weeks versus a vehicle control in patients with progressive primary open-angle glaucoma despite IOP control. The secondary objectives are to measure the changes in BCDVA, visual field, ERG and structural changes in ganglion cell layer and nerve fiber layer thickness measured by optical coherence tomography. The secondary outcomes will be examined at 1, 4 and 8 weeks of therapy, and at 4 and 24 weeks after cessation of therapy (Week 12 visit and Week 32 visit), and will include functional assessments to investigate evidence of a persistent biological effect after discontinuation of the study treatment.
This study focuses on glaucoma therapy by drug eluting contact lenses. The contact lens will be loaded with timolol maleate and dorzolamide hydrochloride, both of which are commonly used ophthalmic drugs. Additionally, the lenses will contain vitamin E ((+) α-tocopherol) as an additive for achieving extended release of the drugs. This study is to assess the safety of the drug loaded contact lenses and the effectiveness. Effectiveness will be a drop in IOP after using the lenses.
Phase II, randomized, double-masked study to evaluate the efficacy and tolerability of topical ocular delivery of fixed-dosed combinations of trabodenoson and latanoprost in subjects with Ocular Hypertension or Primary Open-Angle Glaucoma. All subjects who meet the study's enrollment criteria following Screening will undergo washout of all prohibited medications (if washout is needed), including their routine glaucoma medications. During the Placebo Run-In Period, placebo is applied twice daily to both eyes in all subjects. During the Treatment Period, study drug is applied to both eyes for a total of 8 weeks. Each subject will be assigned 4 weeks of AM and 4 weeks of PM dosing in a masked manner. AM vs PM dosing is masked utilizing Placebo in addition to the active drug product. During the Treatment Period, study drug (Active and Placebo) eye drop applications will occur twice daily, in the morning and in the evening. The Treatment Period will be followed by an Observation Period of approximately 7 days wherein no study eye drops are instilled. The purpose of the study is to assess the overall benefit/risk profile of binocular topical application of different doses of trabodenoson (3.0% and 6.0%) when combined with latanoprost (0.005% or 0.0025%) one drop daily (QD) for 8 weeks.
