We have next to consider a group of 10 eyeballs, in each of which the dislocated _cataract was firmly fixed to the ciliary body and to the back of the iris by definitely organised fibrous tissue_ (Pl. III., Fig. 17). These globes present certain well-marked features of some interest: (1) The percentage of Morgagnian cataract is much lower than that in the preceding groups, and corresponds closely with the normal frequency of this form of cataract in Indian practice. (2) The cataract was dislocated _in its capsule_ in no less than 8 of the 10 cases. (3) The retina was totally detached in 2 and very extensively so in one; in every one of the remaining 7 this membrane showed the presence of white dots, apparently on its surface. (4) The time which had elapsed since operation in the cases falling under this group is remarkable. In one it is given as seven months; in 2 others there is no history; in the remaining 7 the duration was from two to twenty years, with an average of well over seven years. The association of the presence of white dots with these long histories is remarkable, and will be taken up in a later section. No. 99 (Pl. III., Fig. 18) is a specimen of special interest for two reasons--viz., (1) the cataract is fixed to the globe unusually far back, being attached to the retina a little behind the equator of the eye; (2) the dislocation has taken place in an upward direction, and therefore against the action of gravity. From time to time we meet clinically with a couched lens whose suspensory ligament, though torn through over a wide circumference, has been spared at one part, which acts as a hinge. The loosened lens flaps backwards and forwards with the movements of the eye, at times obstructing the pupil, and at others being lost to sight. If the hinge is above, the cataract usually blocks the pupil when the head is erect; but one meets with cases in which the lens floats up out of the way unless the face is thrown forward into the horizontal plane; this is apparently due to a check-ligament action of the remaining suspensory fibres of the lens, acting on a lens which is very nearly of the same specific gravity as the vitreous in which it lies. Should inflammation be set up in such an eye and the lens become involved in the exudate, it may become fixed, as in this case, in the upper segment of the globe. PLATE III Fig. 16: Specimen No. 197.--The exudate into the vitreous cavity is abundant and opaque, concealing the dislocated cataract. (Time since operation, one month.) Fig. 17: Specimen No. 37.--The lens is tied to the back of the iris and ciliary body by firm organised exudate, which is continuous with and part of the cone of inflammatory material representing the shrunken vitreous. Notice the advanced organisation evident in the apex of the cone near the optic nerve, also the white line apparently representing the hyaloid canal. Some large dots and many small ones are to be seen on the retina.
