Eyelid Abnormalities (Entropion/Ectropion)
Malformations of the eyelids, particularly entropion (inward rolling) and ectropion (outward rolling), are more common in some breeds due to facial conformation.
Detailed Description
Entropion causes eyelashes to rub against the cornea, leading to irritation and ulcers. Ectropion exposes the conjunctiva, causing dryness and infection. Both are influenced by genetics and breed-specific facial structure.
Common Symptoms
- Tearing
- Squinting
- Eye discharge
- Corneal ulcers
Management Options
- Surgical correction
- Topical medications for secondary issues
