Brachycephalic Syndrome is a common condition of short-nosed dogs (brachycephalics)
in which there are:
- Shallow orbits (or sockets), causing excessive exposure of the eyeballs and a predisposition to proptosis*
- Excessive eyelid length
- Relatively poor blink reflex
- Medial canthal entropion,** causing the eyelid hairs to inappropriately contact the cornea
All of the above result in a predisposition to corneal ulcerations and pigmentary scarring
of the cornea. The condition can be surgically corrected by a procedure called a “medical
canthoplasty”. This procedure removes a portion of the eyelids in the inner corner of the
eye. This removes the medial canthal entropion and shortens the eyelid length. The net
effect is better protection for the eye, decreased corneal exposure and irritation, and
improved long-term corneal health.
*Proptosis is when the eyeball itself is displaced out of the eye socket
**Entropion is rolling inward of the eyelids, such that the eyelid hairs may contact the corneal surface.
Pigmentary Keratitis, or corneal scarring, blocking vision in a pug, (left) and a Shih tzu (right) with Brachycephalic Syndrome. In both cases, the scarring is a result of: 1) excessive exposure of the eyes, and 2) hairs from the lower eyelid entropion constantly rubbing on the cornea.
