Filter by: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 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 the study is to evaluate the neuroprotective efficacy of hyperbaric oxygen for the treatment in patients with optic neuropathy.
The purpose of this research is to evaluate if intervention and education can change the behavior of someone's willingness to see an eye care provider to prevent blindness and glaucoma. The researchers are investigating if adding additional resources improves participant access to care.
This trial is a randomized study to evaluate and compare two doses of the Bimatoprost Implant System used in combination with the SpyGlass IOL to Timolol Ophthalmic Solution in participants with mild to moderate open-angle glaucoma or ocular hypertension undergoing cataract surgery.
As ab externo metal probe trabeculotomy cannot achieve 360-degree circumferential angle surgery, prolene suture can be used to achieve this without the need for an illuminated microcatheter. In order to combine the advantages of the use of viscoelastic and those of circumferential trabeculotomy, this technique (Visco-Circumferential-Suture- Trabeculotomy "VCST") was previously used successfully in PCG. (7) In the current study , the authors hypothesize that combination of VCST with phacoemulsification in primary angle closure glaucoma patients may have an added affect to phacoemulsification alone in cases with more extent of angle damage and that the injection of a viscoelastic into both ends of the unroofed SC before its cannulation by a polypropylene suture and subsequent circumferential trabeculotomy may facilitate circumferential cannulation of SC and hence the trabeculotomy and increase the success of the technique
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.
Abundant evidence indicates that vision and eye health disparities exist due to a disproportionate eye disease burden among high-risk populations. Columbia University Department of Ophthalmology clinical researchers designed the New York City SIGHT Study (NYC-SIGHT-2) to evaluate Effectiveness of a Telehealth-Based Intervention to Detect and Manage Glaucoma Among High-Risk Populations in Community Health Settings in Upper Manhattan. The program begins with a telehealth-based eye health screening, optometric exam, eyeglasses, and referral to ophthalmology. The telehealth-based intervention uses patient navigators and peer ambassadors to improve eye care access, utilization, and adherence to in-office glaucoma evaluation appointment compared to Usual Care, while the study also explores the experiences of enrolled participants and program staff as well as cost-effectiveness of the intervention.
