Signs and Symptoms
The signs and symptoms include itching, redness, and burning sensation of the eye. There will be clear, watery discharge. Rarely pain is also seen. There will be difficulty in looking at the light.
Causes
Allergic response in the eye is often triggered by foreign bodies like dust particles, pollen grains from grass, weeds, or trees. Pet dander, dust mites, etc. can also cause allergy. Some perfumes, petrochemical exhaust are also irritants to eys.
Pathophysiology
When an allergen comes in contact with the antibodies associated with mast cells in the eyes, they respond to them by releasing chemicals called histamines. These substances cause the tiny blood vessels to leak and the eyes become red, itching with clear watery secretions. Foreign body sensations become severe.
