If the corners of the eyes are itchy and there is also mild congestion in the whites of the eyes, it is most likely caused by allergies. Allergies can be perennial, seasonal or acute contact allergies. If there is no eyelid redness or swelling, perennial or seasonal allergies are more common and may be caused by the presence of allergens in daily life. Allergic conjunctivitis then causes itching of the eyes and can be congested. Usually, it is important to deliberately look for or pay attention to which substances cause itchy eyes. Eye drops, such as Olopatadine or Imodium drops, can be used for anti-allergic effects. Alternatively, hormonal drops, such as Flomipramone or Dimethoate, can be used, which are more effective, but not suitable for long-term use.
