[The geographic environment--a risk factor in eyelid tumors?]

The paper shows the role of the geographical environment in the incidence of various ophthalmological diseases and tries to make connections between different factors of pollution and the appearance of cancer, using epidemiological data. In Bihor district, the analysis of ocular tumors during a 25 years period shows 34 cases of malignant melanoma, 6 cases of glioma, 14 epibulbar malignant tumors opposing to 487 palpebral tumors, 3 tumors of the lacrimal sac and 8 cases of trichoepithelioma. Histopathologically, 173 of them were spinal cell epithelioma, 210 were basal cell epithelioma, 48 were sudoriferous, 40 were non-differentiated and 16 16 were mixed forms. The authors propose the district distributed study of the morbidity of various ocular diseases, which lead to the achievement of an ophthalmo-geography.
