Filter by:Assessment and monitoring of intracranial pressure (ICP) changes are important in the management of cerebral pathologies. In the eye, ICP increase and decrease both correlate with optic neuropathies, the former because of papilledema and the latter related to glaucoma. While the relationship between ICP elevation and papilledema is well established, the relationship between low ICP and glaucoma is still poorly understood. So far, ICP monitoring is performed invasively, but this entails risks including infection, spurring the study of non-invasive alternatives. While none of currently methods in use can fully replace invasive techniques, certain measures show great potential for specific applications. In this context, monitoring the intracranial pressure changes of normal tension glaucoma may lead to a better understanding of how intracranial pressure waves vary in normal tension glaucoma. Treatment of normal tension glaucoma as a two-pressure disease needs periodic intracranial dynamic monitoring sessions for evaluation of treatment effectiveness and for needed corrections of treatment methodology. Project aim is to be able to monitor the "missing link" of intracranial dynamics of patients with normal tension glaucoma according to circadian rhythm: in the morning, during lunch and in the evening. The opportunity to monitor ICP waves non-invasively for patients with normal tension glaucoma will be implemented for the first time by using novel non-invasive intracranial pressure waves real-time monitoring system invented by KTU team in 2022 (patent applications are in the process of registration in the EU and USA).
This study intends to conduct visual function examinations and follow-ups on two groups of glaucoma patients, one receiving visual perceptual training and the other serving as a control without training. The aim of this study is to explore the effects of visual perceptual training based on the lateral masking paradigm on patients' visual function. Additionally, synchronized EEG-fNIRS signals will be collected to investigate whether changes in patients' visual function are accompanied by corresponding alterations in brain function.
The aim of this study is to create a large-scale register of all glaucoma patients diagnosed, followed and treated in a large tertiary centre specialising in glaucoma, in order to analyse whether specific factors influence the progression of the disease or guide our choice of treatment. This should lead to a better understanding of the disease and the factors to be taken into account when choosing the best treatment option for each patient, leading to safer, more effective and patient-centred care.
The objective of this study is to collect data for the development and validation a screening process using aggregate data. In this study, data collection will encompass both retrospective and prospective approaches across multiple sites in the United States.
The purpose of this Post-Market Clinical Follow-Up (PMCF) study is to assess long term clinical performance and safety outcomes for EX-PRESS Glaucoma Filtration Devices Models P-50 and P-200.
Two primary care-based screening systems will be used to identify subjects with referrable glaucoma to hospital care. Subjects between 55 to 65 years old living in two primary care areas (urban area in Lisbon ; countryside setting in Minho) will be invited to a one-time assessment of optic disc and intraocular pressure (IOP). Criteria for referral will differ between centers, with one arm (Lisbon) using an artificial intelligence (AI) reading software of the optic disc picture, the other (Minho) will base their referral based on optical coherence tomography (OCT) retinal nerve fibre layer abnormality. A masked reading center will be established to set the ground truth for diagnosis. This pilot screening trial will explore the level of agreement between both systems as well as their cost effectiveness and identify diagnostic composite scores that could maximize the screening process. Secondary analyses will include the identification of population characteristics that increase effectivity of screening process as well as determining the population less likely to adhere to screening programmes.
Micro pulse transscleral laser treatment (MP-TLT) is a relatively new method to reduce the intraocular pressure (IOP) in glaucoma. New recommendations regarding the treatment protocol has recently been developed and was published 2022. The overall objective is to evaluate the efficacy and safety of the proposed treatment method in an independent study. In addition, the outcome of MP-TLT in patients with pseudoexfoliation glaucoma, which is relatively common in the Nordic countries, and primary open angle glaucoma will be studied separately. The IOP change over the course of one year will be monitored, as well as success rate and survival. Further, patient-reported discomfort from the treatment and the occurrence of any adverse events or complications will be studied.
This observational study will enroll adults with open angle glaucoma (OAG) who had surgery to reduce intraocular pressure (IOP) using the CycloPen Micro-Interventional System. Consenting participants will be followed for 24 months after their surgery. Data regarding IOP, use of glaucoma medications, and any side effects related to the surgery will be collected from participants' preoperative examination, their surgery, and postoperative examinations.
The study will assess safety and performance of MINIject implant in patients with open-angle glaucoma uncontrolled by topical hypotensive medications in conjunction with cataract surgery.
Retrospective collection of data from medical records, multicenter, post-market clinical follow-up study.
