Haw's syndrome
From Cat
Haw's syndrome is a common eye disease of cats, characterised by bilateral elevation of the third eyelids. In many cats, it is a temporary occurrence seen when a cat wakes from sleep, or is sick. All other aspects of the ophthalmic examination normal. This problem normally resolves in 3-4 weeks without treatment, and often reflects malaise due to other underlying problems, such as:
- parasites
- Cat Flu or other viral infections
- Tranquilization: many tranquilizers (e.g., acepromazine) cause bilateral elevation of the third eyelid. Fatigue can cause transient third eyelid elevation, especially in cats prone to ectropion.
- Horner's syndrome
- Dysautonomia (Key-Gaskell syndrome)
