Summary
Ectopic cilia (EC) in dogs are successfully treated by surgical removal of the hair follicle. This condition often causes corneal lesions unresponsive to medical therapy and should be suspected in such cases.
Area of Science:
- Veterinary Ophthalmology
- Canine Dermatology
Background:
- Ectopic cilia (EC) are anomalous hair follicles originating from the meibomian glands of the eyelid.
- They can cause significant ocular discomfort and damage in dogs.
Purpose of the Study:
- To review the clinical data and outcomes of dogs diagnosed with ectopic cilia.
- To identify common breeds, affected locations, and associated conditions.
Main Methods:
- Retrospective study of 112 dogs diagnosed with ectopic cilia.
- Data collected from multiple private veterinary practices in France.
Main Results:
- The most common breeds affected were Shi Tzu, French Bulldog, English Bulldog, and Chihuahua.
- The upper eyelid was implicated in 93.5% of cases.
- Corneal complications, including keratitis and ulcers, were statistically associated with short ectopic cilia (75% of cases).
- Surgical removal of the hair follicle was successful in 88.4% of cases.
Conclusions:
- Ectopic cilia is a rare condition treatable by surgical hair follicle removal.
- Suspect EC in cases of corneal lesions that do not respond to medical treatment.
