Biometric Changes After Intervention of Anterior Chamber Angle : an Observational Study
The drainage angle in the anterior chamber of the eye mediates the outflow of aqueous humor, and pathological changes here can lead to high intraocular pressure and glaucoma. Minimally invasive glaucoma surgery, particularly angle surgery, has advanced recently, allowing clear visualization of angle structures like the trabecular meshwork and Schlemm's …
Long-term Safety and Efficacy of a Modified Suprachoroidal Silicone Tube (SST) Shunt
The goal of this observational study is to evaluate the long-term safety and efficacy of a modified suprachoroidal silicone tube (SST) shunt in treating patients with primary open-angle glaucoma (POAG) and pseudo-exfoliative glaucoma (PXG). The main questions it aims to answer are: Does the SST shunt maintain intraocular pressure (IOP) …
Assessment of Endothelial Glycocalyx in Patients With Primary Open-angle Glaucoma
The glycocalyx is a fibrillary lining structure that covers the inner surface of blood vessels. Composed of glycoproteins and polysaccharides, it is an essential determinant of vascular endothelial physiology: it limits coagulation activation and adapts capillary perfusion. Studies have shown glycocalyx alteration in various vascular and autoimmune pathologies such as …
Comparison of Cytokines Profile in Aqueous Humor and Tear Before and After UCP Treatment
Glaucoma is the leading cause of irreversible vision loss in people aged 50 years and older worldwide, second only to cataracts. Ultrasound Cyclo Plasty was first proposed as a new minimally invasive technique in the 1980 s. In recent years, many clinical studies at home and abroad have confirmed the …
Vitreopapillary Interface and Optic Disc Morphology
The vitreous fills the posterior chamber of the eye and is firmly attached, at the posterior pole, to the macula and the optic nerve head (ONH). With formation of a stepwise posterior vitreous detachment (PVD) exerted tractional forces could influence retinal functioning. Especially in patients with glaucoma the influence of …
Anterior Segment Optical Coherence Tomography Microstent Positioning
The goal of this observational study is to learn about the long-term results of glaucoma stent surgery in men and women 18 or older who have had cataract and microstent surgery in the past 2 years at the Moran Eye Center. The main questions the study aims to answer are: …
Visual Field Progression and RNFL Change After PreserFlo MicroShunt Implantation
The trabeculectomy is the gold standard in glaucoma surgery, nevertheless often postoperative interventions have to be done. (1),(2) The PreserFlo MicroShunt (Santen, Osaka, Japan) implantation occurs without critical steps of trabeculectomy. (3) According to a study a 20% eye pressure reduction was achieved in 53.9% of patients one year after …
Data Gathering for A10900
The objective of this study is to gather Optical Coherence Tomography (OCT) data on normal and diseased eyes
Optimize Pediatric OCT Imaging
Handheld optical coherence tomography (OCT) has become an important imaging modality to evaluate the pediatric retina. The objective of this pilot study is to compare a new contact OCT system (Theia Imaging) with an investigational noncontact OCT system (Duke Biomedical Engineering) to assess their ability to image the pediatric retina. …
Multimodal Retinal Imaging in the Detection and Follow-up of Alzheimer's Disease
Because of a shared ontogenic origin, the retina displays similarities to the brain and spinal cord in terms of anatomy, functionality, response to insult, and immunology. Hence, the retina can be approached as an integral part of the central nervous system. The occurence of ocular manifestations in several neurodegenerative pathologies, …
