    SOME PEOBLEMS OF PEESBYOPIA.* GEORGE M. GOULD, M.D., PHILADELPHIA. When r began practice I did as I had been taught regarding the correction of presbyopia. Text-books, teachers, and general custom agreed that presbyopia began sometime after forty, and that no mydriatic was needed in such patients. There was a rough rule wan-j dering about that plus spherical lenses of one diopter were needed in forty-five-year-old patients, twos at fifty, threes at sixty. This was about the time of the “Punch, Brother, Punch with care, a blue slip ticket for a five- cent fare, etc.” Actual dealing with presbyopic pa- tients soon brought me up sharp. Eules like those of the street car conductors would not work out in the ocu- list’s office. If any rules at all were admissible they had to be of a different kind from those of the text-books; in some ways far more definite, in others more indefinite. Some of these cautions I have brought to clearness are as follows: 1. In oncoming and progressive presbyopia, cyclo- plegia IS generally necessary to obtain the static refrac- tion on which the presbyopic correction is based. Piecisely in eyes whose accommodation powers is be- mg narrowed and lessened is the mydriatic most needed in order that eyestrain may not be increased by the function is being compressed. ^ of accommodation produce the injury taking that presbyopic. This is a truth so self-evident and too commonly ignored in our country. ^ - ^ ^ Jghtest misplacing of the axis of astigmatism, l<nl nlrPUt American Med- Hc tne lUfty-flfth Annual Session. June. 1004.
