Itchy bumps at the corners of the eyes are usually considered to be allergies, which may be acute contact allergies or seasonal allergies, as well as perennial allergies. Seasonal allergies are the most common, especially during the spring and fall seasons, and are usually caused by pollen, dust or grass seeds. These allergies are mainly itchy eyes and may become more itchy the more you rub them. There may be small bumps on the inside of the eyelids, or papillae, both of which are a typical sign of allergy and usually require topical anti-allergy medication. In acute contact allergy, the eye itch is often worse and the congestion in the white of the eye is more severe. Most acute allergies are caused by special exposure to certain gases or objects and often require topical and oral medication. Perennial allergies can also lead to chronic allergies, mostly caused by substances in daily life, such as animal hair or dust mites, and are usually treated with topical anti-allergy eye drops.
