[Testing of macular function (author's transl)].

The readaptation time was used to test the function of the macula. After illumination of the macula with an ophthalmoscope the time was measured until the initial visual acuity was reached. Our findings are that the readaptation time of patients with degenerative lesions of the macula is significantly prolonged in comparison with normal controls. Furthermore the readaptation time in cases of exsudative-proliferative processes was longer than in cases of dry lesions of the macula. In clinical practice this method gives a good estimate of the functional state of the macula.
