Redundant meninges indicate atrophy of the optic nerve, which has a normal diameter of 4 mm. The central retinal artery and vein run side by side in the horizontal plane and the artery is usually nasal (remember Army/Navy: Artery/ Nasal) and the vessels can be seen clearly in blocks taken within the most anterior 6 mm of the optic nerve after the point of entry of the vessels. If the correlation of sectorial atrophy or demyelination in the nerve is of importance in a case in which there was a defect in the visual field, a razornick in the superior dura of the nerve can be helpful in orientation after Indian ink or Alcian blue is applied to the posterior surface of the block.
General: size, shape, colour, degree of transparency. This of course varies with fixation. 2. Opacities: a white anterior subcapsular fibrous mound indicates previous or continuing iridocyclitis. A posterior opacity occurs in diabetes or after topical steroid therapy, and detachment surgery, but it is often non-specific. 3. Fixation artefact rapidly causes lens opacification and this process is accelerated by rupture of the capsule. NB: In neonates, the posterior lens surface is concave. Vitreous 1.
The detached retina becomes gliotic and white (*), particularly if silicone oil was used and strands of blood vessels and glial cells (arrowhead) link the different parts of the retina. Note the equatorial encircling bands of preretinal traction bands ultimately progress to a “funnelshaped” or “table-top” deformation of the detached retina. 3. Depigmentation in the retinal pigment epithelium seen as round white areas behind the equator are due to cryotherapy. Pigment rings around smaller white areas are the result of laser burns.
