Teaching eye pathology
Cornea from an elderly female with gradually deteriorating vision Corneas make up a significant proportion of our workload. Most of our corneal specimens fall into four categories: endothelial failure, dystrophies, infections or interference with vision (eg scarring or ectasia). This specimen is full thickness cornea, with the epithelium on the right and endothelium on the… Continue reading Eye pathology case 8
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
During yesterday's microscopy session, we chatted about relative frequency of uveal melanoma in humans vs cats and dogs. I didn't know that certain dog breeds with higher numbers of melanocytes are prone to oral melanomas! Just came across this recent open access review of canine melanomas as potential models for human melanomas: Canine Melanomas as… Continue reading Microscopy November 2019
During yesterday's eye pathology session, we chatted about a variety of cases with a focus on benign and malignant tumours. Cases viewed included an angiosarcoma (rare in our practice) and a choroidal melanoma (very common for us). The latter had previously been treated with radiotherapy, and the eye had developed rubeotic glaucoma. On microscopy, I… Continue reading Microscopy October 2019
