    SnrULTANEOUS RIIPTUEE OF TJIE CHOROID AND PAR- ETIC MYDRIASIS WITHOUT PARESIS OE ACCOMMODATION. J{Y ALEXANDER DUAKE, M. D. NEW YORK. Tlie publication of Dr. de Schweinitz's interesting case in the ]\Iav number of the Record has impelled me to report a quite similar case from my own practice. John H., aged 13^ came to my office June 6, 1889. Two months before had been struck in the left eye by a corn cob, thrown at him l)y another boy. The blow was so severe that he fainted, and when lie came to he had to be kept in bed and in a dark room for two days. The eye was much suffused at the time. The pupil was dilated; according to his father's statement, more so than now. At the present time, both pupils large; left slightly larger than right. On exposure to light, right contracts to 3 mm. Contraction of left pupil, whether produced by light (direct or consensual reac- tion) or by convergence, is imperfect, the pupil always retaining a width of not less than 6 mm. V, li—each: rejects all glasses. Accommodation normal in each eye. Muscles normal in all respects. In left eye two faint ruptures of the choroid, close to the disc and concentric with it; one, below the disc, running nearly hori- zontally, the other, to the upper temporal side of the disc, running obliquely. The two areas of rupture intersect near their ends, forming an obtuse angle. No pigmentation in their vicinity, and fundus otherwise normal. The points of similarity between this case and that reported by Dr. de Schweinitz, are: 1. The coexistence of a rupture of the choroid with a paretic mydriasis, both evidently produced by the same traumatism. 2. The peculiar bifurcated form of the rupture. 3. Tlie retention of normal vision in the affected eye.
