he retina, as also by thesubretinal fluid. In the marginal zone of the macula, wherethe retina is thickest, the opacity is most marked, so that thecentral depression, which is the thinnest portion, appears morefright red by mn||-nj;t.- on the other hand, the red color ^//^ 01 tne choroid shines through more distinctly than in otherkinds of macular opacities, because the retina is thin in the 1 ^ region of the fovea on account of the atrophy of its elements. ^^^^^^Occasionally, after the retinal detachment has lasted for sometime, an actual perforation may even be observed in the centerof the fovea. The detachment, which in this case occupies the temporalquadrant of the eye-ground, is quite superficial—that is tosay, not very far removed from the choroid. In the macularregion there is an hypermetropia of 4.0 D ; toward the periph-ery the hypermetropia is 7 to 8.0 D, while at the papilla theeye is emmetropic. Vision is reduced to power of countingthe fingers at a distance of 3 meters.

Retinal Bands and Retinal Detachment after aPunctured Wound of the Eye.—Four years after an insig-nificant injury of the eye from a sharp piece of tin, which hadpierced the sclera to the temporal side of the cornea, visionbegan to deteriorate. As the picture shows, there was agrayish-white exudate, spherical in shape, in the outer andupper portion between the corneal border and the equator,projecting some distance into the vitreous, seen in the pictureat the left lower border. Below this exudate, which occu-pied the site of the puncture (and touching it above in thepicture), the retina was detached, and this detachment ex-tends some distance along the upper border. Wherever theretina is detached the color is paler, and we see folds andirregular tortuous vessels somewhat darker in color than theother vessels in the picture. Between the detachment (inthe lower portion of the eye) and the exudate are a numberof white bands or lines, some of which anastomose, althoughi
