Allergic eyes (conjunctivitis)
Allergic eyes (conjunctivitis) are inflammation of the tissue layers (membranes) that cover the surface of the eyeball and the undersurface of the eyelid. The inflammation occurs as a result of an allergic reaction and may produce the following symptoms:
- Redness under the lids and of the eye overall
- Watery, itchy eyes
- Swelling of the membranes
Eczema (atopic dermatitis)
Eczema (atopic dermatitis) is a condition commonly found in individuals with other allergic conditions (asthma and allergic rhinitis) but is not usually caused by direct allergen exposure. The rash results from a complicated inflammatory process. Common features include:
- Dry skin associated with significant itching
- Involvement of the face, behind the elbows, and behind knees, though the rash can occur anywhere
Hives (urticaria) are skin reactions that appear as red, raised, itchy welts and can occur on any part of the body. Short-lived (acute) hives are often due to an allergic reaction to a food or medication, though they commonly result from a viral infection in children. Hives that recur over a longer period of time (chronic hives) are rarely due to an allergic reaction, and the underlying cause is typically more complicated. Hive symptoms are:
- Raised, red, welts that resolve over hours to a day
- Intense itching (not painful)
- Many cases are also associated with swelling (particularly of the lips, face, hands, and feet)
