Research into the causes of blindness will benefit from the second annual Western New York 5K VisionWalk at 10 a.m. Sunday in Delaware Park. Registration begins at 9. Dogs and strollers are welcome.

Hundreds of walkers, including many who are visually impaired, are expected to take part.

Following the walk, there will be children’s activities, as well as a bounce house, entertainment and various refreshments.

Proceeds will support the Foundation Fighting Blindness, which is sponsoring studies into prevention, treatment and cure of retinal degenerative diseases such as retinitis pigmentosa, macular degeneration and Usher syndrome.

Chairwoman of the walk is Sarah Malburg, of West Seneca, a music teacher and mother of two whose career has been interrupted by Stargardt disease, a genetic retinal condition that has diminished her eyesight.
