Non-leaky (Type 1) macular blood vessels and age-related macular degeneration

The Impact of Non-Exudative Type 1 Macular Neovascularization (MNV) on Age-related Macular Degeneration (AMD) Progression

NIH-funded research Utah State Higher Education System--University of Utah · NIH-11123162

This project looks at whether a quiet, non-leaking form of new blood vessels in the macula helps protect vision in people with age-related macular degeneration.

What this research studies

You would have high-resolution retinal scans and precise, location-based vision tests that focus on the area near the Type 1 macular neovascularization (MNV). The team will map retinal structure and sensitivity to see if tissue next to the non-exudative MNV stays healthier while surrounding areas decline. Tests include advanced imaging and fundus-controlled perimetry done over time to compare nearby versus distant retinal function. The researchers aim to reduce testing burden in future work, for example by using automated image analysis.

Who could benefit from this research

Good fit: People with age-related macular degeneration who have (or are suspected to have) non-exudative Type 1 macular neovascularization and can attend detailed imaging and vision-testing visits.

Not a fit: Patients with active leaking (exudative) MNV on ongoing anti-VEGF treatment, those without Type 1 MNV, or those with vision too poor to complete perimetry are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If confirmed, this could help doctors identify eyes that are naturally protected and guide monitoring or new protective treatments for AMD.

How similar studies have performed: Observational reports suggest non-exudative Type 1 MNV may slow degeneration, but direct, spatially resolved proof using high-resolution imaging and perimetry is limited, so this approach is relatively novel.
