Optic disc dimensions, body length, and body weight

Editor,—In the optic disc, all visual afference originating in the photoreceptors of more than 1000 mm2retina is concentrated on an area of about 2 mm2 to 3 mm2. The retinal ganglion cell axons are nowhere else so densely and tightly packed as in the optic nerve head. It explains the importance of the optic disc for anomalies and diseases of the optic nerve. Regarding the marked interindividual variability of the size of the optic disc,1 we undertook the present study to evaluate whether the dimensions of the optic disc are correlated with the length and weight of the whole body. ### CASE REPORT The study included 517 white subjects (243 women, 274 men) with a mean …
