Dander allergy is one that is caused by skin flakes, saliva and urine found in many domestic pets, including dogs and cats. Ocular symptoms of allergies are the result of other systemic, or bodily, reactions to the presence of an allergen. The body treats allergens like a harmful agent and fights it with the immune system, much the same way it responds to a virus or bacteria.
Redness
The presence of dander in the air or on an allergic person's body can lead to mild to moderate ocular side effects. Redness is a common symptom of allergies. The All About Vision website suggests that allergies can even cause pink eye, or conjunctivitis. Pink eye is a condition where the eye and eyelid are inflamed due to irritation or infection.
Swelling
The area surrounding the eye can become swollen due to dander. Signs of swelling include puffy eyelids, darkness below the eye or difficulty opening the eyes fully.
Itching
Itching is a common eye reaction to dander. Individuals may feel as if sand is in the eye or that no amount of rubbing reduces the itching. It is important to keep the hands away from the eyes, because this can introduce more dander into the eye, and it can spread what is already present.
Stinging
Dander can lead to stinging in the eyes. Rubbing to relieve itching can exacerbate this symptom and lead to a sensation of burning in and around the eye. The University of Maryland Medical Center points out that sometimes an individual may experience sinus pressure from dander allergies. This pressure is felt behind the eyes or next to the nose where sinus cavities exist.
Watery
The American Academy of Allergy, Asthma and Immunology points out that pet allergies contribute to eye watering. This reaction is the body's way of trying to clear the dander from the eye.
