Ectropion in Dogs

Category: Eye
Breeds documented: 6
Published sources: 8

Overview

An eyelid that hangs outward can expose the moist inner lining instead of fitting closely against the eye. This is called ectropion and often involves eyelids that are too long. Exposure makes the lining more vulnerable to irritation and recurring inflammation, sometimes with bacterial infection. It may affect both eyes as part of facial structure, while scarring or facial nerve damage can cause an outward turn in one eyelid.

Signs to watch for

An eyelid edge that droops or turns outward
Redness of the exposed inner eyelid
Discharge from the eye
Watery eyes

In a UK study, half of first diagnoses occurred by about two years of age.

When to get help Arrange a vet visit for an outward-turning lid with redness, watering, or discharge.

Diagnosis and tests

A vet checks how the eyelids sit against the eyeball and looks for exposed, inflamed tissue. Bright light and magnification help assess the eyelid edge and the eye surface. Routine eye tests may include tear measurement and dye staining to look for dryness or damage to the cornea, the clear front covering.
