Two-Year Update on All May See Research Awards

Every year, All May See awards grants to Ophthalmology researchers to facilitate preliminary studies focused on novel approaches to discover the causes and treatments for a wide range of vision problems. In 2021, a total of $200,000 in award grants were provided for the following projects:

Project Title: National Eye Institute (NEI) Center Core Grant for Vision Research
Principal Investigator: Erik Ullian, PhD

Findings: The acquisition of a state-of-the-art Zeiss LSM900 Airyscan 2 confocal microscope was made possible with NEI funds and a generous gift from Don and Judy McCubbin. This microscope is crucial for the success of numerous NEI-funded projects. To ensure its optimal performance, the All May See grant funds the cost of two additional years of service contract to maintain the microscope in excellent condition.


Project Title: Elucidating Mechanisms of Visual Pathway Damage in Alzheimer’s Disease
Principal Investigator: Alexander Smith, PhD

Findings: The research discovered that amyloid beta peptides associated with Alzheimer’s Disease accumulate in the optic nerve and the sclera. These findings offer a novel mechanistic explanation for vision loss in Alzheimer’s disease. Dr. Smith intends to seek National Institutes of Health (NIH) funding to further this research in collaboration with the National Institute on Aging.


Project Title: Mechanisms of Retinal Degeneration in Alzheimer’s Disease-Related Dementias
Principal Investigators: Li Xuan Tan, PhD (Postdoctoral Fellow in the laboratory of Aparna Lakkaraju, PhD)

Findings: Dr. Tan’s investigation shed light on the mechanisms responsible for impaired visual function in frontotemporal dementia (FTD). The research discovered specific defects in energy production and metabolism in the tissue that nourishes and protects the retina, leading to inflammation and loss of the light-sensing cells of the eye, resulting in progressive visual deficits.


Project Title: Enabling Direct Correlation of Choroidal Blood Flow and Retinal Degeneration at the Single Vessel Level and Over Time Using Transscleral Multiphoton Microscopy
Principal Investigator: Henk Shang, PhD (Postdoctoral Fellow in the laboratory of Tyson Kim, MD, PhD)

Findings: The research team made significant progress in developing transscleral imaging and analytical methods to study changes in blood vessels within a genetic model of retinitis pigmentosa. Their findings revealed significant shrinking of blood vessels and diminished blood flow in diseased eyes, prompting further investigation into the correlation between these changes and the progression of retinal degeneration.



Project Title: Transcutaneous Orbicularis Oculi Stimulation for Temporary Eyelid Closure
Principal Investigators: Nailyn Rasool, MD (pictured) and Julie Schallhorn, MD, MS (not pictured here)

Findings: The principal investigators (PI‘s) successfully developed a prototype device in partnership with the Prototyping Lab at the Cleveland Veteran’s Administration Hospital. This prototype effectively induced temporary lid closure. The ability to induce lid closure will be extremely effective in patients with neurodegenerative conditions preventing lid closure as well as in patients with neurotrophic keratopathy. The goal is to prevent the development of thinning and ulceration of the cornea without permanent closure of the eyelid. The PI’s have also filed for intellectual property protection for this device design. Additionally, they established a connection with Israeli company Neurotrigger, who are working on a similar device to act as a blink pacer for patients with Bell’s palsy. Dr. Schallhorn joined their team as a consultant and aided in the development of plans to bring their device to the US, pending FDA approval.
