Congenital Lid Anomalies

Front 1

Ankyloblepharon

Back 1

1.Partial/Total lid fusion
2.associated with craniofacial abnormalities
3.Fixed surgically

Front 2

Blepharophimosis

Back 2

1.tight, short fissures, poor lid function, no levator fold
2. AD
3. may require surgery, usually once nasal bridge has formed

Front 3

Coloboma

Back 3

1.Notch/Full thickness due to incomplete closure of maxillary mesoderm
2.usually unilateral & SN
3.corneal dryness, may have microphthalmos, iris coloboma, polar cataract
3.small defects has good prospects, larger ones depend on location
4.TX- AT, surgery

Front 4

Cryptophthalmos

Back 4

1.abnormal lid development causing partial/total eyebrow absence, fissure, conj, or eyelashes
2.Tx- focus on expanding the orbitto prevent hypoplasia by surgery

Front 5

Distichiasis

Back 5

1.eye lashes growing out of meibomian gland, usually finer than regular lashes
2.aquired or congenital
3.sometimes treatment is more damaging than condition
4.AT, epilation, cryotherapy, electrolysis

Front 6

Epiblepharon

Back 6

1.redundant skin and orbicularis muscle causing turning in of lower lashes & lid
2.spontaneously clears, but can be corrected surgically
3.more common in asians

Front 7

Epicanthus

Back 7

1.vertical skin folds overlying the medial canthal tendon
2.bilateral usually due to immature facial bones
3.more common in asians
4.can be treated surgically after 4-5 yo

Front 8

Euryblepharon

Back 8

1.horizontally wide palpebral fissure often due to insertion of lateral canthal ligament
2.causes poor blinking,lid closure, & exposure keratitis
3.treat with AT if mild, and surgery if severe with corneal pathology

Front 9

Microblepharon

Back 9

1.rare, vertical shortening of eyelids
2.dry eye symptoms
3.AT, surgical rotation of skin flaps & skin grafts for severe corneal involovement

Front 10

Telecanthus

Back 10

1.increased distance between medial canthi, due to long ligaments
2.seen in fetal alcohol syndrome
