Abstract
A simple geometrical method is described of calculating the retinal magnification factor (micrometres/degree) at the ora serrata of the human eye. At the ora the magnification factor is some 176 microns/deg., whereas at the posterior pole it is 276 microns/deg. This result may be of clinical use in examinations where dimensions of tears and holes near the ora serrata are estimated.
