What is Epicanthus inversus?
Epicanthus Inversus: Skin fold arising from the medial lower eyelid and ascending to the upper eyelid (see below). Epicanthus inversus has high specificity for BPES and occurs bilaterally. Telecanthus: Increased distance between the medial canthi.
What causes BPES syndrome?
BPES is caused by a mutation in a gene called FOXL2, which controls the production of the FOXL2 protein. This protein, in turn, is involved in the development of the muscles in the eyelids as well as the growth and development of ovarian cells.
What is Blepharophimosis ptosis Epicanthus inversus syndrome?
People with this condition have a narrowing of the eye opening (blepharophimosis ), droopy eyelids (ptosis ), and an upward fold of the skin of the lower eyelid near the inner corner of the eye (epicanthus inversus). In addition, there is an increased distance between the inner corners of the eyes (telecanthus ).
What causes small eye openings?
Blepharophimosis is a congenital anomaly in which the eyelids are underdeveloped such that they cannot open as far as usual and permanently cover part of the eyes.
What does Epicanthus mean?
Epicanthus or epicanthal fold is a semi-lunar fold of skin at medial canthus, with its concavity facing outward. The epicanthal fold obscures the view of the medial canthus including caruncle and plica semilunaris. This is the most common congenital lid condition. This condition does not pose any problem to the eye.
What causes Epicanthus?
The risk is the same for males and females. In some individuals, the disorder is due to a spontaneous (de novo) genetic mutation that occurs in the egg or sperm cell. In such situations, the disorder is not inherited from the parents.
What is the Epicanthus?

What is the outer canthus?

What is epicanthus inversus syndrome?
It is also part of a syndrome blepharophimosis, ptosis, and epicanthus inversus syndrome, also called blepharophimosis syndrome, which is a condition where the patient has bilateral ptosis with reduced lid size, vertically and horizontally.
What is blepharophimosis ptosis and epicanthus inversus Syndrome (BPES)?
Blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES) is a condition that mainly affects development of the eyelids. People with this condition have a narrowing of the eye opening ( blepharophimosis ), droopy eyelids ( ptosis ), and an upward fold of the skin of the lower eyelid near the inner corner of the eye (epicanthus inversus).
Where does epicanthus tarsalis originate and inversus originate?
Epicanthus tarsalis originates at the upper eyelid crease and merges into the skin near the medial canthus. This is the type most often found in East Asians. Epicanthus inversus runs from the lower eyelid skin over the medial canthus and extends to the upper lid. Uighur girl, Central Asian, with the trait.
What is another name for the epicanthic fold?
For other uses, see Mongoloid (disambiguation). An epicanthic fold or epicanthus is a skin fold of the upper eyelid that covers the inner corner (medial canthus) of the eye. However, variation occurs in the nature of this feature and the possession of ‘partial epicanthic folds’ or ‘slight epicanthic folds’ is noted in the relevant literature.
