In dealing with the ocular complications of pregnancy, I shall try to present the bearing of recent pathologic investigations on the cause of serious eye disturbance. Medical literature shows that there is scarcely an eye disease which has not been more or less directly traced to the pregnant state. Some of these we now know are not distinctively so caused. Pregnancy, at most, increases liability by lessening resisting powers. Power1 published three interesting papers, claiming that, among other complications, pregnancy produced a definite type of superficial central ulceration of the cornea.
