Researchers at the WashU Medicine John F. Hardesty, MD Department of Ophthalmology & Visual Sciences are developing an innovative approach to visual acuity testing with modified eyeglasses designed to improve exam efficiency, stability and accuracy. Developed by ophthalmology residents Glory Mgboji, MD and John Wilson, MD the device offers a hands-free alternative to traditional eye occluders used during eye examinations.
A Hands-Free Approach to Visual Acuity Testing
Visual acuity testing is an essential part of an eye examination, helping clinicians assess vision and guide the diagnosis, prognosis and treatment of ophthalmic conditions. However, traditional testing methods often require patients to hold an eye occluder while clinicians use additional tools to evaluate vision.
Holding an occluder in place can be challenging for patients with neuromuscular weakness, tremors or altered mental status. To address these challenges, the modified eyeglasses integrate eye occlusion and pinhole testing into a wearable device. The glasses can also accommodate corrective lenses when needed.
The device allows clinicians to alternate occlusion between the eyes by rotating the occluder and pinhole components, potentially reducing the need to remove or reposition equipment throughout the examination.
Resident Collaboration Drives Clinical Innovation
The prototype has been developed and is being used with patients, offering an opportunity to explore how this approach may support more efficient and reliable visual acuity assessments.
“It has been exciting to design and implement the occluder glasses alongside our co-residents. We’re grateful for the opportunity to collaborate on an innovation that can improve exam efficiency and patient care!” said John Wilson, MD
The innovation reflects the value of resident collaboration in identifying practical clinical challenges and developing solutions that may improve the patient experience. The technology is featured in the WashU Innovation Catalog through the university’s Office of Technology Management, with a patent pending.
