    RETAINED PURILLARY MEMBRANES. C. T., a lady of advanced years, has been greatly near- sighted since childhood. In early life she suffered from an attack of granular conjunctivitis, which was followed by con- siderable distortion of the lids. In recent years there have been complaints of serious intraocular disturbances. The fundus of each eye shows signs of recent and remote chorioretinitis with numerous hemorrhagic foci. The margin of the right pupil is remarkably crenated, and, extending obliquely across it, from near the larger curvature of the iris, and from the upper nasal to the lower temporal quadrant, is a great broad pupillary band. There are no other congenital anomalies noticed. I. W. H., aged 19, who resides in northern New Jersey, 12 miles from the residence of the lady whose eye has just been described, and who presented himself as I was dismissing the lady, is also a myope. In his healthy and otherwise normal right eye, are two broad pupillary bands which are arranged as the diverging sides of an angle, the apex above. The points of contact are well toward the base of the iris. The pupil is round, and reacts perfectly; during its reactions the bands become alternately taut and slack. Just as I finished the transcription of these notes, a lady of 27 presented herself, complaining of asthenopic symptoms. In her right eye are festoons of membranous bands extending over more than the entire nasal half of the iris circle, and stand- ing out free into the anterior chambers.
