The authors investigated in a prospective investigation 27 patients of different age groups for 5 to 12 years with symmetrical, bilateral non-hereditary retinal drusen. The examination was focused on assessment of different types of drusen, on evaluation of the development and incidence of risk factors leading to complications and loss of central vision. The latter include the part of the spectrum of pathological manifestations in higher age groups which are included in the category of senile macular degeneration.
