Conjunctival mapping biopsies from an elderly patient This conjunctival specimen is folded, which is why we have epithelium on the top and bottom of the image. The epithelium is disorganised and has lost its normal maturation pattern. That is, for much of the specimen we don't have a neat basal row of small cells with… Continue reading Eye pathology case 12
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
Orbital mass in a young adult This is a low power image. The tumour is solid (as opposed to eg cystic or nested). There are prominent vascular spaces with an irregular "staghorn" profile. In the annotated image, I've outlined a few of the irregular vessels in green. In this higher power field, we see the… Continue reading Eye pathology case 10
Evisceration of a blind eye with multiple previous operations Evisceration specimens usually include the cornea (with a scleral rim) as well as the intraocular content. In contrast to enucleations, the tissue is disrupted by the surgery. This can make it difficult to recognise anatomic structures, especially as there is often scarring and disorganisation due to… Continue reading Eye pathology case 9
