Allergens From Cats and Cockroaches May Increase Glaucoma Risk – WSJ
Exposure to cats and cockroaches may increase the risk for glaucoma, but contact with dogs could guard against the common eye disease, suggests a study in the American Journal of Ophthalmology.
People with glaucoma had significantly higher levels of immunoglobulin E (IgE), a type of allergic antibody, to cats and cockroaches, compared with people without glaucoma, the study found. Levels of IgE are elevated in various immunological disorders, such as asthma and hay fever, raising the possibility the immune system plays a role in glaucoma, the researchers said. Elevated IgE doesn’t mean a person has an allergy.
