ECTROPION
• Tarsal plates
– Length 25mm
– Thickness 1mm
– Height
• Upper 10mm
• Lower 4mm
ECTROPION
• Orbicularis Oculi
– Orbital
– Palpebral
• Preseptal
• Pretarsal
ECTROPION
• Medial canthal tendon
– Anterior Limb
– Posterior Limb
– Superior Limb
ECTROPION
Lateral canthal tendon
• Inserts posteriorly along
the lateral orbital wall
ECTROPION
• Orbital septum
– Origin
• Arcus marginalis
– Insertion

•
Medial: posterior lacrimal crest
Lateral: orbital tubercle
Superior: levator aponeurosis
Inferior: inferior tarsal border

ECTROPION
• Definition
– Abnormal eversion of the eyelid away from the
globe
• Key Features:
– Eyelid margin and lash drive are turned away from
the cornea
– Conjuctival surface is exposed, which can lead to
keratinisation of the epithelium
– Corneal exposure results in foreign body
sensation, corneal dryness and ulceration
