Fig. 247.—Section through the coats of the eye showing a tubercular mass C in the choroid. A, Retina; B, sclerotic. confluence of the nodules causes the choroid to become con- siderably thickened, large caseating patches forming in the centre of the mass (Fig. 248). The membrane of Bruch with the pigment epithelium lining it soon becomes destroyed. The retina becomes detached. Sometimes, owing to invasion of the retina in the neighbourhood of the disc, it undergoes extensive necrosis so that hardly any of its elements can be recognised microscopically. Where the retina is detached the sub-retinal fluid is of an opaque grumous consistency, and is seen microscopically to contain a quantity of fatty globules in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Collins, E.
