[The value of the cytological exam in the diagnosis of allergic conjunctivitis].

Cytologic investigations was performed in four groups of patients: central group (10 cares), without pathologic lesions; 12 patients were admitted with allergic conjunctivitis (with positive allergy tests, atopic state or clinical manifest allergic diseases), 20 cases with bacterial conjunctivitis; 8 cases with mix allergic and bacterial conjunctivitis (that hardly respond to therapy). Smears from the conjunctivae secretion were air-dried and stained with blue-polycrometanin Drăgan method. Cytologic lesions characteristic for each group of patients are described. Our results suggest that cytology from the conjunctivae secretion is helpful in the diagnosis of the allergic etiology; also, it accurately the allergic components mix conjunctivitis.
