The yellow area, which appeared highly reflective on fundoscopy, is a post-inflammatory retinopathy where retina has died with resulting tapetal hyper-reflectivity. This may well be caused by a migrating Toxocara larval challenge as the dog was not wormed as a pup. Incidentally this lovely indirect view was taken with Optibrand’s Clearview system, a great new device for those of you who are gadget-mad like me!
