Purpose: The incidence of conjunctival carcinoma is about 1.2 diseases per annum per million persons in Germany. In nearly half of the patients with atopic dermatitis chronical inflammation of eye-lids, conjunctiva and cornea is described. Because chronical inflammation is a predisposition for the development of cell dysplasia and malignoma, a correlation of neoplastic developments with atopic keratoconjunctivits is suspected. Since October 2000 all patients with atopic keratoconjunctivitis who consulted our clinic were examined cytologically and cytometrically. In 8 cases conjunctival carcinoma was diagnosed.

The primary examination was done by cytological and cytometrical methods. The differentiation into carcinoma in situ and invasive carcinoma was done by biopsy.
Results: One patient with a maligne diagnosis in the cytological/cytrometrical examination refused the necessary bioptic differentiation. Histopathological differentiation in 7 out of 8 patients reveiled carcinoma in situ in
