Filter by:Glaucoma, a leading cause of irreversible blindness worldwide, is characterized by a permanent loss of retinal ganglion cells (RGCs), a group of central nervous system (CNS) neurons that convey visual information from the retina to the brain via their long axons. Clinically, axonal damage in RGC results in a loss of visual field and may lead to blindness. Currently, reducing eye pressure remains the sole target of proven glaucoma therapies. However, many patients continue to lose vision even when standard interventions are implemented, accentuating the unmet need for novel therapies. Dendrites are processes that determine how neurons receive and integrate information. Dendrite retraction and synapse breakdown are early signs of several neurodegenerative disorders. In mammals, CNS neurons have an extremely limited capacity to regenerate after injury. To date, the ability of mammalian neurons to regrow dendrites and reestablish functional synapses has been largely ignored. Insufficient insulin signaling has been implicated in diseases characterized by dendritic pathology, notably Alzheimer's disease and glaucoma. A versatile hormone, insulin readily crosses the blood-brain-barrier and influences numerous brain processes. In a mouse model of optic nerve transection, our team showed that insulin administration after optic nerve injury promoted robust dendritic regrowth, RGCs survival and retinal responses rescue, providing the first evidence of successful dendrite regeneration in mammalian neurons. Our research validates insulin as a powerful medication to restore dendritic function in glaucoma, forming the basis for using insulin as glaucoma treatment in humans. Currently, insulin is approved for diabetes. Adverse events of systemic insulin include hypoglycemia, hypokalemia, lipodystrophy, allergies, weight gain, peripheral edema and drug interactions. Experimental use of ocular topical insulin have been tested in small cohorts of healthy individuals and diabetic patients, reporting no significant adverse events. However, these protocols varied in insulin posology and adverse events were only touched upon briefly, indicating the necessity to better characterize the safety profile of such off-label use of insulin before its application as a neuroprotective and regenerative treatment for glaucoma. In this study, the investigators hypothesize that topical ocular insulin (up to 500 U/ml) at once per day dosing is safe in patients with open angle glaucoma.
Intraocular pressure (IOP) is the most important modifiable risk factor to prevent and delay progression of glaucoma. IOP reduction has been proven to delay the onset and progression of glaucoma, and uncontrolled IOP is constantly associated with progression of visual field loss. Medical therapy is the first line in IOP reduction for Primary Open Angle Glaucoma (POAG). It is a known fact that glaucoma patients often require addition of a second antiglaucoma medications when disease progresses or tachyphylaxis occurs. It was reported that more than 50% of patients require 2 or more medications to achieve optimum IOP control. Nevertheless, compliance and adherence are often impaired with multiple-drug therapy. Combining two ocular hypotensive agents in one bottle may help patients adhere to therapeutic regimen by reducing the number of medications used and the total number of doses administered.
The purpose of this research study is to compare the effect of Netarsudil and Timolol on eye pressure and blood vessels of the back of the eye.
To evaluate the long term safety of repeat dose OTX-TP, a sustained release travoprost drug product, placed in the canaliculus of the eyelid in the treatment of subjects with open-angle glaucoma or ocular hypertension.
This is a multi-centre, open label, interventional, comparative, phase I study to identify a safe and efficacious dose (within the range of 14.7mcg to 35.5 mcg) of PA5108 (PolyActiva product code) Latanoprost free acid (FA) sustained release (SR) Ocular Implant in adults who have Primary Open Angle Glaucoma.
This is a randomized, double blind study with competitive enrolment, aimed to enroll a total of 70 patients with a diagnosis of primary open angle glaucoma (POAG). Patients, after signing the Informed Consent, will enter into a 1- week screening phase during which the baseline tests will be conducted. Subjects will be randomized in a 1:1 ratio to the following groups: - group A of 35 patients treated with pressure lowering drugs and placebo; - group B of 35 patients with pressure lowering drugs and COQUN oral formulation 100 mg BID.
To measure the efficacy and safety outcomes of SLT performed by optometrists.
To compare the safety and efficacy of Perrigo's product to an FDA approved product in the treatment of Primary Open Angle Glaucoma or Ocular Hypertension in Both Eyes.
In addition to intraocular pressure blood perfusion pressure in the optic nerve is an important factor determing the cause of glaucoma. Increasing evidence suggests that in glaucoma patients retinal blood may be decreased.
Glaucoma represents a group of conditions that cause damage to the optic nerve and can lead to irreversible vision loss. Current treatments are aimed at lowering intraocular pressure while minimizing medication side effects. Lumify™ (Brimonidine Tartrate Ophthalmic Solution 0.025%) is an FDA-approved medication for alleviating eye redness, a common side effect of glaucoma medications. The purpose of this study is to evaluate the effect of Lumify™ on eye redness, intraocular pressure, and eyelid position in patients with glaucoma who are already using the Brimonidine 0.1%, 0.15% or 0.2% eye drops.
