What is Entropion?
Entropion is an eyelid condition that occurs when the eyelid turns inwards towards the eye. Entropion occurs in the lower eyelid, but can also affect the upper eyelid.
The condition causes friction, discomfort and irritation of the eyelid margin and ocular surface. Eyelid margin and ocular surface irritation over time lead to erosions of the cornea and eventually sight loss if left untreated. The clear cornea acts as a barrier to protect the inner surface of the eye from infections.
Using artificial tears and lubricating ointments relieves symptoms of entropion, but entropion surgery is usually needed to fully correct the condition. Conservative measures can be taken if patients are not fit or motivated for entropion surgery.
There are four types of entropion:
- Involutional entropion – the most common type and occurs due to ageing
- Acute spastic entropion – caused by problems with the ocular surface
- Cicatricial entropion – caused by scarring on the inner surface of the eyelid
- Congenital entropion – occurs since birth and is the rarest type
