Fig. 30: Specimen No. 72.--The operation scar can be seen on the temporal side of the sclera behind the equator. The choroid and retina are extensively detached on this side, having evidently been pushed before the instrument before it succeeded in penetrating them. To the nasal side in the anterior part of the vitreous chamber lies a cone of exudate, the apex of which (posteriorly) is adherent to the retina, and has raised it from its bed in the form of a shallow bleb. The cornea fell in during preparation; it was ulcerated. The anterior chamber was full of pus and blood. What is left of the lens lies buried at the base of the cone of exudate already referred to, being bound thereby to the ciliary body and to the back of the iris. Fig. 31: Specimen No. 171.--A whole-section of the eye shown in Fig. 19. For details of description refer to that figure. Fig. 32: Specimen No. 171.--Low-power magnification of a portion of the specimen shown in the previous figure. To the right is seen the inflamed and matted iris; beneath this lies a mass of inflammatory exudate in which the curled remains of the lens capsule can be traced. In this mass of exudate the lens nucleus lies imbedded, its margins being surrounded by large phagocytes. Fig. 33: Specimen No. 171.--High-power magnification of portion of the previous specimen, showing some of the phagocytes much enlarged. Notice their processes invading the lens substance.

The interest of this observation centres in the fact that a large number of these globes were removed with the object of guarding against the occurrence of sympathetic ophthalmia, or of making safer the performance of an extraction in the opposite eye. So far as the first indication is concerned, it would appear that the danger of sympathetic mischief in the second eye after couching is not great. The deduction thus drawn from pathological data is confirmed by the author’s clinical experience, for, as far as his observations go, it is extremely rare to see the second eye lost by sympathetic ophthalmia after this operation. =The Chambers of the Eye.= =The Anterior Chamber.=--This chamber showed departures from the normal in different directions. These will be dealt with under separate headings.
