Distichiasis and Ectopic Cilia
Distichiasis and ectopic cilia are eyelash disorders where abnormal hairs grow from the eyelid margin or through the conjunctiva, irritating the cornea.
Detailed Description
Distichiasis involves extra eyelashes emerging from the meibomian gland openings, while ectopic cilia are hairs growing through the conjunctiva. Both can cause chronic irritation, tearing, corneal ulcers, and pain. These conditions are more common in breeds with prominent eyes.
Common Symptoms
- Excessive tearing
- Squinting
- Corneal ulcers
- Pawing at eyes
Management Options
- Removal of abnormal hairs (manual, cryotherapy, electroepilation)
- Topical lubricants
- Surgical correction for severe cases
Frequently Asked Questions
Can distichiasis be cured?
It can be controlled, but recurrence is possible.
Is surgery always needed?
Not always; mild cases may be managed conservatively.
Are breeds with prominent eyes more prone to eye ulcers?
Yes, due to both eyelash disorders and their eye anatomy.
