VP Research — Aging Health Sciences

Dr. Murray H. Brilliant is a Professor of Ophthalmology at the University of Arizona and one of the world’s foremost researchers in the genetics of eye disease. With four decades of experience in mouse and human genetic research, Dr. Brilliant has spent his career working to understand the molecular underpinnings of vision and how they change with age.

He headed the research project that identified L-DOPA’s relationship to age-related macular degeneration — a discovery that became the scientific foundation for MaculaPM®. His team’s retrospective analyses, published in the American Journal of Medicine, found that patients taking L-DOPA developed AMD later than expected, supporting the rationale for exploring this pathway in the context of macular health support.*

Dr. Brilliant holds a Doctorate in Molecular Cell & Developmental Biology and brings an exceptionally deep scientific perspective to the MaculaPM® formulation — from the molecular level up through clinical application.

"L-DOPA is not just a signaling molecule — it sits at a unique crossroads of retinal biology that no other eye supplement has addressed."

A Closer Look at Retinal Biology

The retina depends on a critical support layer called the Retinal Pigment Epithelium (RPE). RPE cells produce melanin pigment, and a byproduct of that synthesis process is L-DOPA. As we age, melanin synthesis in the RPE slows, reducing natural L-DOPA production. This reduction appears to be more pronounced in lightly pigmented individuals and typically accelerates after age 60.

In the eye, L-DOPA functions as a signaling molecule that interacts with GPR143, a G-protein coupled receptor. Research indicates that this signaling relationship influences the regulation of VEGF and supports the activity of PEDF, a protein naturally secreted by the RPE that scientific literature associates with neuroprotective activity, photoreceptor support, and healthy management of blood vessel growth.

Melatonin contributes to the circadian regulation of these processes. Because both L-DOPA and melatonin production decline naturally with age, MaculaPM® is designed to provide dietary support for these pathways during a period when the eye's own production may be diminished.
