The physical examination of selectees to determine acceptability for induction into the armed forces affords a unique opportunity for estimating the incidence of various ophthalmic conditions in a comparatively large and statistically significant group of men. This study consists of an analysis of the results of my examination of 60,000 men, a consecutive series, at an armed forces induction station. MATERIAL AND METHOD These men represented an age group of from 18 to 38 years, together with a few enlistees aged 17 and selectees between 38 and 45 years of age. Thus, ophthalmic conditions peculiar to childhood, puberty and senescence were not encountered. In addition, preliminary "screening" examinations, performed by physicians at the various local selective service boards, eliminated from the group some who were obviously visually unfit. It is readily apparent, therefore, that the incidence of the various conditions recorded here can be applied only to a comparable group,
