This cat has a corneal sequestrum – not a difficult diagnosis if you’ve seen one before. But also it has entropion in both eyes, as is seen here where there is a milder sequestrum and a corneal ulcer in the other eye. Quite which came first is a bit tricky to judge – did the hair abrading the cornea lead to the ulcer and the sequestrum, or did ocular surface irritation result in blepharospasm and lid in-turning? Which ever is was, both need surgical correction.
