[The fundus oculi in chronic anemias].

The investigation was carried out in 168 cases thus selected as chronic anaemia to be the only affection. In 49 patients (20%) the following changes, single or associated, were found: retinal pallor in 15% of the cases, superficial retinal bleedings in 6%, deep bleedings in 3.5%, retinal exudates in 4.7%, retinal edema in 3%, papillary edema in 1.7%. In all the 49 cases Hb levels were under 6 g%, anaemia was present for more than 2 years, and the etiological type of anemia were studied. The lower the Hb level, the more pronounced and in larger number of cases the retinal alteration. Therefore, the decisive effector of the injuries was the anemic hypoxia. Pleading for this is the disappearance of all retinal alterations after the antianemic treatment.
