Filter by:The purpose of this study is to evaluate the effect of microdrops vs. standard eyedrops of 0.5% timolol maleate in adults with primary open-angle glaucoma or ocular hypertension in terms of intraocular pressure-lowering efficacy and cardiovascular side effects.
Prospective, double-masked, randomized, multi-center, active-controlled, parallel-group, 3-month study assessing the safety and ocular hypotensive efficacy of TearClear latanoprost Ophthalmic Solution, 0.005% (TC-002) compared to latanoprost Ophthalmic Solution, 0.005% (LAT) in subjects with elevated intraocular pressure at approximately 20 study sites located in the United States
Glaucoma is a common eye disease that can lead to blindness. The only known way to reduce the rate of disease progression is by reducing the pressure in the eye (the intraocular pressure, IOP). Selective laser trabeculoplasty (SLT) is an ophthalmic laser intervention with the purpose of reducing the IOP. SLT can be performed in different ways, with four of the treatment protocols being evaluated in the Optimal SLT (OSLT) trial. SLT is a repeatable procedure, but scientific evidence is scarce regarding more than one repetition. In this trial, patients included in the OSLT trial will be invited to the extended trial (OSLT-R), for further follow-up and re-treatment with SLT, if needed.
Glaucoma is a progressive optic neuropathy that results in a loss of contrast sensitivity and visual field if not detected and treated. When glaucoma patients undergo cataract surgery, they are often not ideal candidates for many existing presbyopia correcting IOLs as they reduce contrast sensitivity because of the splitting of light and are more likely to have visual disturbances secondary to diffractive steps in the IOL design. This is largely because of a higher rate of ocular surface disease and meibomian gland dysfunction in this patient population due to the chronic utilization of topical drops. As a result of this, patients with glaucoma currently receive aspheric monofocal IOLs during cataract surgery, which are lenses with minimal loss of contrast sensitivity but only one point of focus (typically targeted for distance). This necessitates the use of glasses for near and intermediate vision and has an impact on quality of life for these patients. The Vivity Extended Depth of Focus (EDOF) IOL is a new technology that maintains uncompromised distance vision and provides improved intermediate vision correction, reducing the need for glasses. This lens uses a new optical system with no diffractive steps in the IOL; trials in non-glaucomatous patients have shown the rate of visual aberrations to be comparable to an aspheric monofocal IOL which are currently the standard of care in patients with glaucoma. There is no published data on outcomes of this IOL in patients with primary open angle glaucoma (POAG) or ocular hypertension (OHT). Studies are required to evaluate the clinical success of this new lens technology in glaucomatous patients. This will be the first study in Canada to report clinical outcomes of the Vivity IOL in this patient cohort.
The objective of this study is to evaluate the effectiveness (Intra-Ocular Pressure lowering) and safety of Direct Selective Laser Trabeculoplasty (DSLT) in ethnic Chinese subjects with Primary Open Angle Glaucoma or Ocular Hypertension.
Glaucoma is a chronic optic neuropathy whose main modifiable risk factor is an abnormally elevated intraocular pressure. The aim of glaucoma treatment is to slow the progression of the disease by reducing intraocular pressure. Prostaglandin derivatives are the most effective topical drugs in reducing intraocular pressure (IOP). Among these, latanoprost was the first agent of this type to be approved for use in patients with glaucoma or ocular hypertension. These eye drops are available with and without preservatives. There are two commercial brands in our environment, Xalatan®, which contains 0.005% latanoprost and 0.2 mg/ml benzalkonium chloride (BAK) and Monoprost®, which contains the same amount of latanoprost but does not carry a preservative. The prostaglandin analog with a lower concentration of active ingredient available in Spain without preservative is tafluprost 0.0015%, commercially available under the name Saflutan®. The long-term use of hypotensive eye drops with preservatives generates changes in the ocular surface, such as instability of the tear film, conjunctival inflammation, subconjunctival fibrosis, apoptosis of the conjunctival epithelium and deterioration of the corneal surface, causing symptoms such as stinging, tearing, sensation foreign body, photophobia and blurred vision. This research will evaluate the changes in the ocular surface and in the expression of inflammatory molecules that occur in the conjunctiva in patients with a diagnosis of glaucoma and ocular hypertension who are under ocular hypotensive treatment with tafluprost, comparing it with the two commercial preparations of latanoprost. These three groups of patients will have a control group of patients with a diagnosis of ocular hypertension who will not have any topical hypotensive medication.
This is a randomized, Investigator-masked, multi-center, parallel group, therapeutic equivalence study with clinical endpoint.
Clinical, cross-sectional and prospective study to assess the images of the posterior pole of the retina of patients from the Glaucoma Unit of the IOBA and the Hospital Clínico Universitario de Valladolid during the period between May and December 2021. The aim of the project is to provide a sufficient number of images from posterior pole retinographies in patients with suspected glaucoma or with diagnosis of glaucoma in order to determine the sensitivity and specificity of an automatic glaucoma screening algorithm developed by the company Transmural Biotech S.L.
The goal of this study is to understand if SLT performed at low energy is as effective as SLT performed at standard energy, and also to see if repeating SLT at low energy once a year will prevent or delay the need for daily eye drop medications better than waiting for SLT to wear off before repeating it.
This is a pilot, open-label, multi-center clinical study. Each potential subject that has met all screening inclusion/exclusion criteria will undergo a six-week washout phase where they will discontinue the use of their topical hypotensive medication. After the six-week washout, each potential subject will return for a baseline visit. Investigators will verify that a potential subject has discontinued the use of their topical hypotensive medication(s) and all their prohibited systemic medications for the last 6 weeks. In addition, each subject will have discontinued the use of all other ocular drops, gels or ointments 24 hours prior to the visit (Visit 2) and continues to meet all screening and washout criteria. After completing the baseline examination, each potential subject that meet all baseline inclusion/exclusion for the treatment phase of the study will have his/her lower puncta of each eye inserted with a Travoprost Evolute®. Each study subject will be instructed to return to the investigator's office the next day, 7, 28, 60 and 90-days after the insertion of their plugs for follow-up examinations.
