Entropion
What is Entropion?
Entropion is the in-turning of an eyelid and is far more common in the lower eyelid than the upper eyelid.
Who is at risk of Entropion?
- Older age - this is a common condition caused by laxity of the lower eyelid (due to ageing and gravity), allowing the eyelid flop inwards.
- Recurrent eye infections - It may be associated with previous eye infections causing scarring of the conjunctiva inside the eyelid thus pulling it inwards, for example trachoma.
- Eyelid muscle spasms
What are the symptoms of Entropion?
As the eyelid turns in, both the eye lashes and the dry skin rub on the cornea (causing corneal abrasion), leading to foreign body sensation and significant discomfort. The eye may become red, produces mucus and waters. Pulling downwards on the eyelid with a finger may provide temporary relief.
How is Entropion diagnosed?
The in-turning of the eyelids may be quite evident, or it may be intermittent and require careful examination to observe this. Slit-lamp examination is also necessary to look for conjunctival scarring.
How is Entropion treated?
Initially lubricating eyedrops or ointment can be used to provide some symptomatic improvement. Pulling the eyelid down/out with fingers or taping it down with sticky tape can also be beneficial. However, these do not provide a long-term solution and eyelid surgery is usually required to tighten the eyelid and turn it into the normal position. The eyelid usually heals very well with minimal scars to be seen after healing.
What if Entropion is not treated?
The eye will continue to be uncomfortable and can result in corneal abrasions and infections which can be sight-threatening. Therefore, surgery is usually recommended.
