    great distortion of images and reduplication of them. Slight grades often overlooked ; high degrees may be easily seen, especially in profile. If eye is illuminated by ophthalmo- scope, a central red reflex is seen surrounded by a dark ring, outside of which is a second bright red ring. By throwing light from differ- ent angles, side of cone opposite light is seen in shadow. If fundus is examined, everything appears distorted. Treatment unsatisfactory. Little improvement of vision from glasses. Stenopeic slit occasionally of use. All straining of eyes must be avoided. Opera- tive treatment comprises iridectomy, iridode- sis, trephining, and Graefe's operation, which consists in removing superficial flap from apex of cone and cauterizing part a few times with nitrate silver, so as to produce a shrinking cicatrix, and so flatten protrusion. Kerato-globus : Hydrophthalmia : Buphthalmos (Gr. |3ous, an ox, and ocpZaXixns, eye] : Is uniform spherical bulging of entire cornea and neighboring part of sclerotic, gen- erally associated with increased size of anterior chamber and tremulous iris and lens. Con dition generally congenital ; may appear after inflammation. Cornea may remain transpar- ent or become cloudy, especially at margin. Causes great impairment of vision, changes in deeper tissues and often ultimate blindness. Treatment of little use. Iridectomy seems tc do most good.
