Dermoids are congenital growths that form in various parts of the eyes, including the cornea, conjunctiva, eyelids and nictitating membrane. Hair grows in abnormal locations and irritates the eye until ulcers form. Depending on the location, dermoids can cause pain and excessive tear production.

Considerations
-
Dermoids can also interfere with proper blinking, which inhibits eye lubrication and causes dry eyes, according to Pet Education.com.
Features
-
Dermoids most commonly affect one eye, but can be in both eyes, according to ThePetCenter.com.
Types
-
Large breed dogs, such as St. Bernards and German shepherds, along with short-legged breeds, like dachsunds and basset hounds, are more prone to dermoids, according to Go Pets America.
Identification
-
One sign of a dermoid is the presence of a white film over part or all of the eye. The surrounding skin might be hairy and/or oddly pigmented.
Prevention/Solution
-
According to Pet Education, surgery is the main treatment. Dermoids are likely to recur if the growth isn't completely removed during excision.
