Abstract Details


Allergic diseases are the most frequent problems in high developed countries. According to WHO allergic conjunctivitis concerns 15-20% population. In half of the patients it is a manifestation of organ allergy, accompanying atopic dermatitis, bronchial asthma, allergic rhinitis and food allergy. The most common diagnostic method is skin test assessing the local reactions to skin allergens introduced in low concentration. In the daily practice we can meet the patients with typical ocular allergy symptoms with simultaneous negative results of skin tests and lack of IgE growth in serum. This phenomenon, described originally in an isolated allergic rhinitis, is called Entopia.

In the Department of Ophthalmology in University Clinical Center of the Medical University of Silesia the study was conducted in 10 patients with typical symptoms of ocular allergy, who previously received negative results of allergy tests. The control group consisted of 10 healthy volunteers, who decided to be tested.


The examination of patients assessing the severity of conjunctival inflammation were performed. The samples of the conjunctiva with dimensions 1x2 mm were taken and they were histological evaluated with particular emphasis on the amount of eosinophils in the field of view in the Department of Pathomorphology in Medical University of Silesia in Katowice.


The described conjunctiva reaction has not been examined so far. This is very important in the diagnosis and therapy, due to the essential tool in the fight against allergies is to avoid the allergen.
