Recent findings: The current review covers the incidence and prevalence of AEDs, factors influencing occurrence and severity of AED (age, sex, socioeconomic status etc.), underlying mechanisms, role of allergy testing and immunotherapy in children, development of diagnostic markers and novel therapies including cells and molecules.
What are some common symptoms of allergic conjunctivitis? Symptoms of allergic conjunctivitis may vary from person to person. They can be very mild or very severe. Itching is the most common symptom; eye allergy is unlikely to be present if itching is not present. Other symptoms may include stinging, tearing, and burning.
