Congenital ectropion is caused by vertical insufficiency of the anterior lamella of the eyelid and may give rise to chronic epiphora and exposure keratitis.,, The association of congenital ectropion involving the upper and lower eyelids bilaterally with Down's Syndrome is relatively uncommon., Mild congential ectropion usually can be managed conservatively. However, severe and symptomatic congential ectropion requires treatment which is similar to cicatricial ectropion. We report a case of Down's syndrome with congenital ectropion and its management.
A 12-year-old female child presented to us with inability to close the eyes completely noticed by her parents since birth along with an abnormal everted appearance of both the upper and lower eyelids on both sides with long-standing exposure keratopathy.
On examination, the child was found to have bilateral grade 4 ectropion of both the upper eyelids exposing the tarsal conjunctiva and also a grade 2 uniform ectropion of the lower eyelids on both the sides. The child demonstrated a vertical anterior lamellar deficiency of all the four eyelids. In addition the corneas in both eyes were vascularized and opacified in the inferior 1/3 due to longstanding exposure keratopathy.
The child was uncooperative for visual acuity assessment as he had significant learning difficulties. We were also unable to perform corneal topography accurately (to rule out accompanying keratoconus which is also a well-known ocular association of Down's syndrome) as the parents were unwilling for a preoperative examination under anesthesia. Ocular examination was otherwise unremarkable with normal pupils, ocular movements, and normal posterior segment. In view of the severe learning disability and less cooperation, the post-operative management was difficult and challenging.
We decided to do the whole procedure in one sitting to avoid recurrent anesthesia and multiple staged surgeries. The precautions taken included avoiding short-acting depolarizing muscle relaxant, using small size endotracheal tube due to airway problems and to avoid sleep apnea we avoided narcotic drugs, an incremental dose of midazolam, and IV paracetamol for pain relief. The child had smooth recovery and post-operative course.
| Discussion|| |
A complete eversion of the upper eyelids occasionally occurs in newborns. Possible causes include inclusion conjunctivitis, anterior lamellar inflammation or shortage or Down's syndrome.,, True congenital ectropion can be primary,, when associated with other eyelid abnormalities and secondary when it accompanies ocular/orbital/skin diseases. Distinctive clinical features help to differentiate the two entities (Congenital eversion of eyelids and True congenital ectropion).
Congenital eyelid eversion, a close differential diagnosis to be considered is an entity characterized by protrusion of the edematous conjunctiva from the everted eyelids. The chemosed conjunctiva protects the cornea and hence corneal complications are rare. The proposed mechanisms include Orbicularis hypotonia, birth trauma, vertical shortening of the anterior lamella or vertical elongation of the posterior lamella, failure of the orbital septum to fuse with the levator aponeurosis, absence of an effective lateral canthal ligament, and lateral elongation of the eyelid. Once everted, the orbicularis spasm may act as a sphincter that leads to a vicious cycle of conjunctival strangulation and edema secondary to venous stasis. This usually resolves spontaneously or improves with non-surgical supportive measures.
In contrast, true congenital ectropion is definitively associated with a vertical anterior lamellar deficiency in the presence of a relatively normal posterior lamella. It is almost always accompanied by lagophthalmos and varying degrees of exposure keratopathy. This usually requires functional eyelid surgery for corneal protection.
Our patient had a simultaneous correction of ectropion of all 4 eyelids by full-thickness skin grafting (the 2 upper eyelids were repaired by grafts from the respective ipsilateral supraclavicular regions and the 2 lower eyelids were corrected by grafts taken from the respective postauricular region). The skin overlying the posterior triangle (supraclavicular region) and over the postauricular region is excellent and relatively non-hair-bearing sites to be considered as donor sites for harvesting full-thickness skin grafts for eyelid tissue reconstruction. Once the line of shortening was released and the defective area of anterior lamellar deficiency was identified, the defect was measured and then the grafts harvested were deliberately chosen to be roughly 30% larger than the aforementioned eyelid defects. This was done to allow for late graft contracture as a part of routine wound healing and to prevent a residual late ectropion. In addition, the two lower eyelids were also tightened by a lateral tarsal strip procedure to tighten the lax lateral canthal tendon to facilitate better eyelid closure [Figure 1].

The combination of lateral tarsal strip procedure to correct the lateral canthal laxity and the replacement of the deficient anterior lamella with full-thickness skin grafts helped in fully correcting the pre-existing ectropion.
We were able to achieve complete resolution of lagophthalmos and prevention of further corneal exposure. The preop, intraop, and postop photographs are being presented [Figure 2].

True congenital ectropion with anterior lamellar deficiency needs to be distinguished from congential eversion of the eyelids that may resolve spontaneously.
We wish to report this case for the relative rarity of occurrence and also to highlight the fact that we were able to correct the four eyelid malposition in a single sitting thus avoiding multiple anesthetic inductions in this child with co-existing systemic concerns.
