    Plate 23. «. Perforation of the Cornea by an Eczematous Ulcer, with Adhesion of the Iris.—Patient is a scrofulous boy, 10 years old, who bad been treated outside of the hospital for the past four weeks, and was admitted at the time of this recent perforation. It is evident from the shape of the perforation that it is due to an eczema-pustule, even without the evidence of eczema in the other eye. There is typical ciliary congestion. The pupil, owing to the adhesion of the iris, is displaced toward the temporal side. A compressing bandage was applied for two weeks, and tlie perforation healed, leaving a smooth, slightly i)igmented scar. The pupillary distortion is permanent. After a few weeks vision was practi- cally restored. I). Macula of the cornea of long standing, the remains of an eczema- tous ulcer. The circular outline of the scar and the loss of cilia indicate that eczema is the causal agent. The eye at the present time is free from irritation. introduced, the malady was most distressing to the patient and a great trial to the jihysician.

It is important to have the patient under good control, .so as to avoid injuring the healthy tissues, hence the .services of a capable assistant are indispen.sable. If the first ajijdica- tion fails to arrest the ])rocess a second should be tried. dhe destruction of the advancing crescent is speedily fol- lowed by cure, as the rich vascularity of the tissues is mo.st favorable to regeneration. It is mo.st important in all forms of eczematous kerat- itis to apply a stimulating remedy at the most favorable moment for hastening the reparative ])roce.‘^s. For this purpose a 1 to 2 ]ier cent, salve of yellow oxid of mercury (well mixed and comminuted) usually suffices. Its use is indicated as .soon as the infiammation has begun to sub- side, when the ulcers are u.sually clean and vessel-forma- tion has begun. The salve fulfils the double purpo.^^e of clearing up the opacities and preventing relapses, and its application must be persevered in for .some time.
