Eye pathology case 15

Cornea from a young adult with gradually worsening vision This low power image shows a full thickness cornea with a little artefactual creasing. Remember, the 5 layers are: epithelium, Bowman's layer, stroma, Descemet's membrane and endothelium. The stroma is perhaps a little thinned towards the right of centre, and there is subtle scarring in the… Continue reading Eye pathology case 15

Middle-aged patient with worsening vision many years after a previous procedure This low power view shows a full thickness corneal button. We've sliced it in two and embedded both halves on our cut surface. It is not obviously inflamed or vascularised (something I specifically mention in my reports as a negative finding). However, there is… Continue reading Eye pathology case 11

Cornea from an elderly female with gradually deteriorating vision Corneas make up a significant proportion of our workload.

This specimen is full thickness cornea, with the epithelium on the right and endothelium on the… Continue reading Eye pathology case 8

Eye pathology case 3

This is a classic exam-type case for the FRCOphth and similar examinations. The patient is a young adult undergoing a corneal graft. (Click on the images to see them full-sized) This is a low power view. Non-keratinising stratified squamous epithelium covers the convex surface. Beneath it lies Bowman's layer (not readily visible at this power)… Continue reading Eye pathology case 3
