Many of the most serious eye diseases develop slowly and without obvious warning signs, which means a person can lose a significant amount of vision before they ever realize something is wrong. That’s what makes regular eye care so critical. Early detection isn’t just helpful, in many cases, it’s the difference between preserving vision and losing it permanently.
At Vision Source Mandan, Dr. Brittany Schauer, Dr. Wayne Aberle, and Dr. Danielle Dyke provide comprehensive eye disease management for patients throughout Bismarck, Mandan, and the surrounding North Dakota communities. With a history rooted in this region going back to 1950, our practice has long been a trusted resource for patients managing both newly diagnosed and long-standing eye conditions.

According to the National Eye Institute, cases of visual impairment and blindness in the United States are projected to double by 2050, driven largely by aging and the rising prevalence of chronic conditions like diabetes. The leading causes of vision loss in this country, glaucoma, age-related macular degeneration, diabetic retinopathy, and cataracts, share a common thread: outcomes are significantly better when caught early.
Routine eye exams do far more than update a glasses prescription. They allow our doctors to examine the health of the optic nerve, retina, and surrounding structures, identifying signs of disease that patients often cannot detect on their own. Dr. Schauer has shared a powerful example of this from her own practice, a patient who came in for a routine exam with no complaints, only to have a serious condition discovered that required immediate medical attention. That kind of discovery is only possible through consistent, comprehensive care.


Our team is trained to detect, monitor, and manage a wide range of eye diseases. We take a proactive approach, using advanced diagnostic technology to track changes in eye health over time and coordinate care with specialists when needed.
Here are some of the primary eye conditions our doctors manage for patients in the Bismarck area:
The most effective thing any patient can do to protect against eye disease is to schedule a comprehensive eye exam every year. Many conditions are entirely manageable when found early, and our team uses that annual visit to build a complete picture of your eye health over time. Skipping even a year or two can create gaps in monitoring that allow conditions to progress undetected.
Our practice serves patients of all ages, from children through seniors, and we tailor our approach based on each patient’s health history, risk factors, and family background. If you have a personal or family history of glaucoma, diabetes, or macular degeneration, let us know so we can prioritize the right screenings for you.
