The Indian operation of couching for cataract

Cataract -- Surgery -- India; Ophthalmology -- India -- History
Fig. 40: Specimen No. 240.--The original cavity of the vitreous
is represented by a mass of blood-clot, surrounded by the walls of the
totally detached retina. The subretinal exudate is firm and abundant.
The iris and ciliary body, the lens remnants, and the anterior part of
the retina are matted together in a dense mass of cicatricial tissue.
Fig. 41: Specimen No. 175.--This shows a proliferative dot in the
retina. R, retina; SCL, sclera; CH, choroid; D, mass of leucocytes
surrounding vessel wall.
Fig. 42: Specimen No. 37.--A collection of leucocytes lying on the
inner surface of the retina, superficial to its limiting membrane, and
projecting freely into the vitreous. In the substance of the retina can
be seen the section of a vessel surrounded by a mass of leucocytes.
Fig. 43: Specimen No. 111.--Small cysts in the retina, which would
probably have coalesced before long to form a larger one.
Fig. 44: Specimen No. 111.--A whole-section of the eye already shown
in Fig. 34. The condition of l’iris bombé is well marked, the
pupillary edges being adherent to an inflammatory mass formed of the
capsule and the anterior layers of the hyaloid matted together. Notice
the large cysts occupying the central area of the detached retina, with
the macula lutea showing in its inner wall.
Fig. 45: Specimen No. 131.--A large Morgagnian lens in its capsule
was adherent to the iris base, the ciliary body, and the neighbouring
retina over a wide area. The capsule ruptured during the transit of
the specimen from India. Note the thickened white dots upon it; they
are characteristic of Morgagnian cataract. The large brown nucleus,
which escaped when the capsule burst, now lies free in the cavity of
the eye; notice the “bite” out of its edge. The optic disc was deeply
cupped, and the angle of the anterior chamber was widely obliterated,
the chamber itself being very shallow.
