Through his eyes: Why an Essentia Health ophthalmologist stresses the importance of eye care

January is Glaucoma Awareness Month. Glaucoma can affect anyone, and studies from the Glaucoma Research Foundation (GRF) show that 4 million Americans have the disease, but only half of them know they have it.

Dr. Cole Swiston, an ophthalmologist at Essentia Health, has dedicated his career to the evolving field of glaucoma care. The condition occurs when the optic nerve connecting the eye to the brain is gradually damaged. This nerve damage, often linked to high eye pressure, leads to a slow and permanent loss of peripheral vision. Tragically, many patients remain unaware of the damage until it progresses significantly, narrowing their field of vision or causing irreversible blindness.

Dr. Swiston’s passion for ophthalmology and glaucoma stems from his love for continuity of care. While building long-term relationships with his patients, he guides them through their eye-care journey. The constant innovation in the field, along with the precision required for delicate surgeries and laser treatments, has always captivated him.

Currently, the only modifiable risk factor for glaucoma is eye pressure. Dr. Swiston employs a variety of treatments to manage this, including eye drops, lasers and surgeries designed to increase fluid outflow or reduce fluid production in the eye. He likens his role to that of a “plumber for the eye,” ensuring the smooth flow of fluids to maintain optimal eye pressure and to prevent worsening of the disease.

“Regular glaucoma screenings are crucial because this silent disease can cause irreversible vision loss before you even notice any symptoms,” said Dr. Swiston. “Early detection is the key to preserving your sight and maintaining your quality of life.”

Dr. Swiston is well-versed in the latest treatments and minimally invasive glaucoma surgeries. He is also well-trained in traditional glaucoma surgery. His expertise extends beyond glaucoma to complex eye surgeries, including routine and complex cataract surgery, surgery for dislocated lenses and pupil repair or replacement.

Living in Duluth and the Upper Midwest, Dr. Swiston is acutely aware of the high prevalence of glaucoma in the region, particularly an aggressive form of the disease known as pseudoexfoliative glaucoma. This is more common among the area’s significant Scandinavian population. Dr. Swiston emphasizes the importance of regular screenings, especially for those with a family history of glaucoma, drawing a parallel to high blood pressure where damage can occur silently.

Dr. Swiston’s training at the Moran Eye Center in Salt Lake City, Utah, has equipped him with knowledge of ever-expanding and cutting-edge glaucoma technology. He now offers innovative diagnostic testing, including one that allows for monitoring eye pressure at home,  and is excited about a new procedure that accesses a separate drainage pathway in the eye to lower eye pressure.

“Embracing the latest treatments and technologies in eye care allows us to provide the most effective and minimally invasive solutions for our patients,” said Dr. Swiston. “Staying at the forefront of innovation ensures we can offer the best possible outcomes and preserve vision for years to come.”

Dr. Swiston acknowledges that eye care may make some people nervous, but he reassures patients that surgeries, including those for glaucoma, have become less invasive, with shorter recovery times and better outcomes.  With a dedicated anesthesia team and his commitment to guiding patients through every step of the process, he’s committed to providing a smooth and painless experience.

“Providing safe and effective eye care is our top priority,” said Dr. Swiston. “We are dedicated to addressing people’s concerns with compassion, clear communication and a supportive team to ensure a comfortable and reassuring experience.”
