This bull, rather unusually, has entropion of the lower lid. In this case we needed to create a large skin defect to be able to evert the lid margin and stop eyelid hair abrading the cornea. Normally in a dog or cat only a ellipse of a couple of millimeters’ width would be needed and the idea is to place it as close to the eyelid margin as possible – a milimeter or so away. Here it was very difficult to evert the lid in the conscious but sedated animal even after injection of local anaesthetic into the lid tissue, so the incision is further from the lid margin than might have been wanted. Neverthless the operation was successful.
