Every spring and fall, itchy, red, watery eyes send thousands of people reaching for antihistamines, but not every irritated eye is reacting to pollen. In some cases, what feels like a familiar seasonal flare is actually a bacterial or viral infection that needs professional care, and treating it like an allergy only delays healing.
At Vision Source Mandan, Dr. Brittany Schauer, Dr. Wayne Aberle, and Dr. Danielle Dyke work with patients across the Bismarck-Mandan area who come in frustrated, having spent weeks managing symptoms with over-the-counter drops that never quite worked. Our eye allergy treatment services are designed to get to the root of what is actually happening with your eyes, not just mask discomfort.
Allergy season creates a layer of noise around eye symptoms that makes accurate self-diagnosis difficult. Pollen, mold, dust, and pet dander all trigger the same immune response: histamine floods the conjunctiva, causing redness, tearing, and itching. Bacterial and viral infections hit the same tissue and produce eerily similar results. When both arrive at the same time of year, it is easy to assume the cause.
The problem is that eye infections do not respond to antihistamines. Reaching for allergy drops when you have a bacterial infection allows the infection to persist, potentially spreading and causing more serious damage to the surface of the eye. According to the American Academy of Ophthalmology, an ophthalmologist uses a slit-lamp microscope to examine the conjunctiva, specifically to separate allergic conjunctivitis from infectious causes before recommending any treatment.
