The cellular exudation in the tissue consists of nodules of lymphocytes and plasma cells. These are present in the iris, ciliary body, and choroid. Occasionally giant cells and large endothelial cells may be present in these follicles. The exudation into the vitreous causes the formation of fibrous tissue which may subsequently contract and de- FiG. 233.—Shows a section through the front part of an eye which had plastic iritis as a result of a perforating wound of the cornea and lens. The iris on the right side is adherent in its whole length to the lens capsule. On the left side it is adherent at the pupillary margin but bowed forward, by fluid unable to pass through the pupil, elsewhere. Case recorded R. Lond. Ophth. Hosp., Reps., XIII, 1890, 55.

Thick fibrinous membranes may occur on the surface of the iris, ciliary body, and choroid. Keratitis punctata occurs in all cases, and occasionally a thick fibrous mem- brane may be found on the posterior surface of Descemet's membrane. If bullae occur on the cornea, the fiuid they contain is rich in fibrin, and a fibrous deposit forms which may organise into a thick, fibro-vascular membrane lying between Bowman's membrane and the epithelium. Finally shrinking of the eye may result. In sympathetic cyclitis the microscopical changes in the sympathising eye are similar to those in the exciting Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of t
