Ectropion:
An eversion of the lower eyelid that may be related to aging, facial nerve paralysis, or scarring. It can lead to eye irritation, tearing, and corneal exposure. Surgical correction restores normal eyelid position and function.
Entropion:
Inward turning of the eyelid margin, causing the eyelashes to rub against the eye surface and leading to discomfort, tearing, foreign body sensation, and potential corneal damage.
Epicanthal Fold:
A skin fold of the upper eyelid that covers the inner corner of the eye. Prominent in some ethnic groups and in certain congenital conditions. An epicanthal fold may be surgically modified for cosmetic or functional purposes.
Eyelid Retraction:
Abnormal elevation of the upper eyelid (upper eyelid retraction) or downward shift of the lower eyelid (lower eyelid retraction) often associated with thyroid eye disease or previous surgery. Treatment may require surgical repair with eyelid lengthening procedures or grafts.
Eyelid Malposition
General term for improper alignment of the eyelids. It includes eyelid ptosis, entropion, or ectropion and retraction.
Epiphora:
Excessive tearing caused by a blockage in the tear drainage system or eyelid malposition such as ectropion. Treatment may include procedures such as dacryocystorhinostomy (DCR) or eyelid surgery to restore proper tear flow.
Eyelid Lesion:
A term used to describe a growth, lump or bump on the eyelid. It may be benign or malignant. An eyelid cyst is an example of a benign eyelid lesion while basal cell carcinoma is a type of malignant eyelid lesion. A lesion may require a biopsy or surgical removal for diagnosis and treatment.
