Glaucoma Clinical Trials

The purpose of this study is to compare the tolerability and comfort of 3 different prototype anesthesia-free tonometer tips with the standard tonometer tip in conjunction with anesthesia. The best-tolerated prototype anesthesia-free tonometer tip will be identified for further development for home tonometry. Read Less

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: 1. How often are microstents mispositioned? 2. What effect does microstent positioning have on intraocular pressure after surgery? Participants will have a one-time clinic visit for an eye exam and Optical Coherence Tomography (OCT) . From the eye exam and OCT, Researchers will assess and categorize the position of the microstents and assess the Schlemm's canal dilation. Researchers will review the participants' medical records to acquire 2-year data for the following: 1. Surgeon type and level of experience (resident, fellow, attending ophthalmologist) 2. Proportions of proper gonioscopic placement intraoperatively for each surgeon group 3. Effectiveness of surgery, based on change in intraocular pressure (IOP) from baseline medicated IOP, number of IOP-lowering medications the patient was able to discontinue, and rate of need for additional glaucoma surgery.

The purpose of this Phase 1 trial is to determine the safety over 1-2 months of topic sterile human recombinant insulin on subjects with optic neuropathies (glaucoma, ischecmic optic neuropathy, and optic disc drusen). Read Less

Glaucoma is a major cause of blindness. The inability to predict a patient's IOP response to medications is a critical barrier for the clinician to consistently provide highly effective IOP-based treatments. Current trial-and-error approaches to glaucoma management are inefficient and have not addressed this barrier as there are no predictive factors for drug response. Our long-term goal is to improve outcomes by identifying biomarkers and environmental factors that profile a patient at risk for glaucoma by age-of-onset, rate of disease progression, "poor response" to treatment, and large IOP fluctuation. Our purpose of this research project is to address this critical barrier by focusing on physiological factors that predict IOP response to drugs. Read Less

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. The investigators hypothesize that the contact OCT system is superior in imaging larger areas of the retina (larger field-of-view), while it has similar resolution to image the retina substructures (non-inferior image quality).

The purpose of the study is to evaluate the neuroprotective efficacy of hyperbaric oxygen for the treatment in patients with optic neuropathy. Read Less

The purpose of this research is to evaluate novel technologies for the assessment of ocular structure and function, including the scanning device called Optical Coherence Tomography (OCT). We will test the OCT and other devices in their ability to image diseases of the eye and also compare the measurements made with OCT to those of other imaging and visual field devices approved by the Food and Drug Administration (FDA). OCT may be useful for the early diagnosis and monitoring of a variety of types of eye diseases Read Less

Perimetry is an essential component in the diagnosis and monitoring of glaucoma. Since the advent of Standard Automated Perimetry (SAP), one of the clinical standards has been the Humphrey Field Analyzer (HFA, Carl Zeiss AG, Oberkochen, Germany). Visual field (VF) testing provided by the HFA is standard-of-care in glaucoma clinics and other ophthalmology and optometry practices. However, the HFA is a large device that does not allow for examination outside the clinic and can be uncomfortable for patients with limited mobility. This study aims to evaluate a novel head-mounted perimeter against the HFA as an alternative method of VF testing. This new perimeter uses a Virtual Reality (VR) headset and a gamified version of VF testing to assess the visual function of healthy eyes and patients. The results of this study will potentially serve as pilot data for the design of a larger study that involves the full assessment of the VR headset and its VF test, based on various testing strategies.

Glaucoma Drainage Device and Endothelial Cell Loss Compare Trial (DECLARE) is a multi-center, outcome-masked, randomized clinical trial. The purpose of this study is to compare glaucoma drainage device implantation in the anterior chamber (front part of the eye) and sulcus (small space between iris and front chamber of the eye) in efforts to minimize cell loss in the eye.

The purpose of this study is to establish autoregulation of retinal blood flow in arterioles and capillaries as a biomarker for early primary open angle glaucoma. Read Less
