About Dr. Bowan
Merrill D. Bowan, O.D.

Oakmont, PA 15139
PROFESSIONAL SUMMARY: Dr. Merrill D. Bowan is a neurodevelopmental optometrist who practiced in the Pittsburgh area for 47 years. Dr. Bowan graduated in 1965 from the Illinois College of Optometry with a B.S. in Optometry and Doctor of Optometry degrees. His pre-optometric studies were performed at Geneva College, in Beaver Falls, PA. He served for three years in the U.S. Navy, attached to the Marine Corps at Parris Island, S.C. His areas of professional interest are treatment of post-concussive syndrome, vision and visual processing in learning and language development, and the psychopathophysiology of refractive error. His later work was in the area of textual visual aliasing caused by sampling errors (binocularly dissonant signals). He also discovered the application of low power prisms (miniprisms, initially called microprisms) in addressing many of the issues of brain hypersensitivities caused by mild traumatic brain injuries (mTBI’s). Those discussions can be found other tabs to the left. He also developed a theoretical model for Palinopsia involving alteration of the episodic nature of the visual stream by the neuropsychophysiological aftermath of brain trauma. (Papers drafted on these topics are linked below.)
He was co-founder and Director of Perceptual Services at the Effective Learning Institute, a multidisciplinary developmental visual and sensorimotor remedial center from 1992-1994. He has served as the director of perceptual training at Pace School (1970-1972); Chairman of the Visual Development and Training Committee of the Pennsylvania Optometric Association; and consultant to the Title I funded perceptual program at The Bradley Center in Dorseyville, PA, for the program’s five-year span.
Dr. Bowan is a member of The Optometric Extension Program, a post-graduate study program. He has lectured for the Regional Gathering of the Pittsburgh Area Mensa Society in 2010, 2011 and 2013, the Connecticut Optometric Association at the Mohegan Sun Resort, the Hudson Valley Optometric Association at West Point, and the San Diego Optometric Association. He has lectured at Carlow University, Duquesne University – in both the reading department and department of special education, Penn State University, Monroeville campus, The Art Institute of Pittsburgh, Penn Technical Institute, and at numerous inservices at local rehabilitation centers, autism support groups, and public and private schools throughout Western Pennsylvania and Eastern Ohio. He was on the editorial review board of Annals of Ophthalmology and Glaucoma from October 1997 until it ceased publication in 2007.
