Fig. 22: Specimen No. 138.--A large Morgagnian cataract in its capsule lies dislocated behind the totally detached retina; the tear in the front part of the lower half of the retina, through which the lens was thrust, is now represented by a wide puckered scar. Fig. 23: Specimen No. 9.--A whole-section showing a persistent fistula of the cornea. Fig. 24: Specimen No. 45.--A brown nucleus dislocated downward in its capsule lies tightly adherent to the back of the iris and ciliary body; it is fixed there by organised exudate, the bands from which radiate out into the retina and are determining the detachment of that membrane. The iris is torn on the nasal side, and through the tear there passes a capsulo-corneal synechia. Fig. 25: Specimen No. 116.--The retina is totally detached, and rolled up like a closed umbrella. There is a retino-corneal synechia. The lens has been reclined; it probably lay outside the vitreous cavity. The subretinal exudate, coagulated by preparation, gives the eyeball the appearance of a cut marble. During life the pressure of the lens, which had been wedged backward, thrust the retina and the parts adherent to it backward below, thus displacing the subretinal exudate there, and causing it to bulge in the upper half of the eyeball; this bulge effectually obliterated the upper part of the anterior chamber, whilst the direct pressure of the lens obliterated the chamber below. Fig. 26: Specimen No. 306.--There is a pigmented scar running through the thickness of the sclera, just behind the level of the ciliary processes. The optic disc is deeply cupped, and the anterior chamber is very shallow. Fig. 27: Specimen No. 306.--Low-power magnification of the previous specimen shows a persistent fistula running through the substance of the sclera; the ciliary body is impacted in its deeper part, and there is a filtering scar on its surface.
