Filter by:The purpose of this clinical trial is to implement acupressure twice daily and monitor the changes in intraocular pressure (IOP) in patients with different levels of glaucoma. The study aims to investigate the effects of this method on IOP, visual field, retinal nerve fiber layer thickness measured by optical coherence tomography, blood vessel density, and macular ganglion cell layer thickness and density in patients with primary open-angle glaucoma (POAG).
The objective of this study is to evaluate the efficacy and safety of glaucoma device in the treatment of primary open-angle glaucoma.
To compare electrophysiological and Optical coherence tomography angiography of optic disc and macula changes after uneventful phacoemulsification between normal and cataractus patients with primary open angle glaucoma.
Study aiming to compare between anterior segment Optical Coherence Tomography and Ultrasound BioMicroscopy In Glaucoma aSSESMENT
EYE-FIT is a randomized clinical trial with a two-arm parallel design aimed at assessing the impact of performing a structured and supervised physical training program on the different variables associated with glaucoma progression in pharmacologically treated primary open angle glaucoma patients. This intervention will include a supervised 24-weeks concurrent (endurance + resistance) training program comparing its influence to the standard care.
Glaucoma is a chronic disease that causes loss of vision and potentially blindness as a result of optic nerve damage due to increased intraocular pressure. Currently, it is the leading cause of irreversible blindness worldwide1. In 2020, 4.1 million and 3.6 million adults over the age of 50 suffered from mild to severe visual impairment and blindness respectively induced by glaucoma1. However, these predictions are likely underestimated since glaucoma can remain asymptomatic until later stages in disease progression2. There is a convincing body of evidence suggesting that there is a linear relationship between visual impairment and decreased quality of life (QOL) among glaucoma patients3. Furthermore, evidence from The National Health and Aging Trends Study suggests that this relationship may be bidirectional where older adults with visual impairment are more likely to suffer from mental illness and older adults with mental illness are more likely to suffer from visual impairment4. Mindfulness-based meditation is a promising non-pharmacological treatment that has been shown to reduce intraocular pressure and improve QOL in patients with glaucoma5. A feasibility study will be conducted using a mixed-method design to assess the feasibility of delivering a meditation intervention online to enhance the QOL and mental health of glaucoma patients. Participants will be recruited and randomized in blocks of 10 and will undergo 1:1 randomization to the intervention arm or usual care arm. The purpose of this block randomization technique is to minimize the wait time between patient recruitment and study initiation. Participants in each arm will complete online questionnaires at patient recruitment, weeks 1, 3, 6, and 12 to measure self-reported health, depression symptoms, anxiety, and sleep quality using REDCap, an electronic data capturing system provided by Lawson Health Research Institute (LHRI).
Clinical Trial to Evaluate the Safety and Effectiveness of a Canaloplasty Device in Subjects with Open-Angle Glaucoma
Microneedle (MN) is a mimic of a hypodermic needle, composed of hundreds of micron-sized, out-of-plane protrusions, typically arranged in arrays on a patch that can be applied onto the skin. MN can be fabricated from a variety of materials, preferably biocompatible polymers. Maltose, a natural carbohydrate, is a safe and biocompatible product that can be fabricated into MNs that are biodegradable and soluble within several minutes. Besides, local anaesthetic agents such as lignocaine can be impregnated within the MN matrix, facilitating its transdermal delivery more efficiently which results in enhanced efficacy. So far, maltose MN efficacy in enhancing the transdermal drug delivery (TDD) of lignocaine and thus reducing the pain experienced by healthy patients requiring intravenous cannulation prior to routine eye surgeries (phacoemulsification, trabeculectomy etc) has not been extensively studied. Hence, the objectives of this research are: 1) To evaluate the safety profile of lignocaine-embedded microneedle patch as a means of pain reduction in adult patients requiring routine vein-puncturing procedures; 2) To assess the pharmacokinetic (PK) parameters of lignocaine in the systemic circulation when the transdermal lignocaine delivery is enhanced through microneedle usage; 3) To compare the efficacy of lignocaine-embedded microneedle patch with standard 5% Eutectic Mixture of Local Anesthetics (EMLA) dermal patch for pain reduction during venepuncture procedure based on mean changes in VAS scores and skin algesimeter index (pharmacodynamic (PD) study).
