In recent times, eyelid injuries are on the rise primarily because of the increasing incidence of road traffic accidents, industrial mishaps and intentional assaults on the human body. Injury to the eyelids, lacrimal system or orbital wall may be isolated or may occur in association with mid facial injuries.


A precise history is essential to assess the severity of injury. In some cases, an ophthalmologist can anticipate the extent and severity of injury from the mechanism of injury. It is important to elicit the mode of injury, whether it is with sharp or blunt objects or due to thermal or chemical injury or due to dog bites. In cases of animal bites a complete tetanus immunization history is obtained and if required proper immunization should be given.

Examination Of The Patient

Patient’s injury must be dealt according to the priority. The basic “ABC’s” (Airway, Breathing, Circulation) must be evaluated, before proceeding to the management of localized injury. Repair of globe takes precedence over repair of eyelid laceration(Fig 1). In adnexal injury the decision whether to repair the wound immediately or to delay repair depends on the degree of tissue edema or the presence of haematoma or infection

The ocular examination should be performed meticulously. Observation of ocular adenxae is done before manipulating the injured eye.


Site of Injury:  Whether the lid margin is intact or lacerated. Injuries in the region of medial canthus may be associated with lacrimal injuries. (fig 2)

A complete blood count and necessary blood chemistry analysis is carried out. Radiologic evaluation is advised when indicated.
All injuries must be documented in detail with drawings and clinical photographs.
In patients presenting within 24 hours of injury, primary repair of the   wound is undertaken immediately.


Principles to be followed for repair:


Primary wound management may be discussed under the following heads:


Simple Lacerations
Smaller linear defects can be sutured without any undermining as they involve only skin and underlying muscle. There should be no tension or vertical pulling effect on the lid margins. Eyelid skin is usually sutured with 6’0 nylon or prolene suture. Non-absorbable skin sutures should be removed in about 5 days. The vertical linear wounds may be broken into multiple Z plasties in order to improve the scar.  If the laceration in the upper lid extends upward to involve the eyebrow, it is essential to align the eyebrow first.



Fig 3 Simple laceration

Deep lacerations  
Deep nonmarginal lacerations require careful layer by layer inspection of the wound to assess the integrity of the orbital septum, levator aponeurosis, rectus muscles, and globe. It requires careful closure in layers. (Fig 4). Subcutaneous closure is done with 5’0 vicryl.

(i) With minimal loss of tissue:

Repair of marginal injuries can be difficult due to swelling. The lid margins should be freshened if devitalized tissue is present, to form straight, smooth surgical edges, sacrificing, as little tarsus as possible. Meticulous closure of eyelid margin is crucial. Inadequate closure can lead to lid notching, lagophthalmos and exposure keratopathy. The margin is repaired using the three-suture technique.
Lid margin sutures are passed first.  A 6-0 silk suture is passed through the grey line 3 mm from the edge of the tear, to a depth of 3mm. This is brought out of the wound and reinserted into the other side of the laceration 3 mm deep to the lid margin and emerging through the grey line 3 mm from the edge of the wound (Fig 5a). The same suture is then passed back into the grey line on the same side, 1 mm from the edge of the tear, to a depth of 1 mm (Fig 5b). The needle is brought out and reinserted into the opposite edge of the tear 1 mm deep to lid margins and emerging through the grey line 1 mm from the margin of the wound. Two more vertical mattress sutures are passed exactly in the same way through the posterior lash line and the other posterior to the gray line. These three sutures are triply tied and ends left long (Fig 5c).5,0 polyglactin sutures are used to reaproximate the tarsus. There is no need to place sutures on the conjunctival surface since it will heal with the approximated tarsal  edges. Skin sutures are removed in 5 to 7 days . Lid margin sutures are left in situ for 10-14 days.

Undue tension should be avoided on the marginal laceration as this may lead to wound dehiscence. Whenever there is tension on the wound, one can use the sliding or advancement flaps.

Fig 5 b- The suture is then passed back into the grey line on the same side, 1 mm from the edge of the tear, to a depth of 1 mm



Fig 5 c – Three marginal sutures are passed and ends are left long

(ii) With moderate loss of tissue : (From one fourth to one half of eyelid).

When there is moderate loss of tissue with involvement of one-fourth to one-half of the eyelid horizontal relaxation of the eyelid is required. This can be achieved by lateral canthotomy and canthloysis of either the upper or lower limb of the lateral canthal tendon, depending on the eyelid involved. 5’0 prolene suture is used to fixate tarsus to the lateral rim periosteum. Subcutaneus closure is done with 5’0 vicryl.
In case the defect is too large to be closed with canthotomy and cantholysis a tenzel semicircular flap can be raised. For upper lid defect, the arc of the semicircle is downwards and for the lower lid the arc is above the canthus. Surgeon may also use transconjunctival flap, or free transconjunctival graft  or Mustarde's marginal pedicle rotation flap for reconstruction.  

(iii) With severe loss of tissue (more than half of eyelid)

For very large defects grafts from the opposite eyelid or surrounding tissue are used for repair. The commonly used techniques are Cutler Beard procedure, Hughe’s tarso conjunctival advancement flap, Mustarde's cheek rotation flap or Free transconjunctival graft and mucocutaneous advancement.



Patient presenting with ptosis should be observed for atleast six months as spontaneous resolution may occur with time. Whenever, the orbital fat is exposed, it indicates disruption of the orbital septum and the wound should be adequately explored (Fig 6). The levator palpebrae superioris (LPS) fibers are identified by their vertical orientation, in comparison with the Orbicularis muscle fibres, which run circumferentially. If the aponeurosis has been disinserted from the tarsus, the cut edge is drawn forwards and reinserted by placing three 5-0 double  arm vicryl sutures through the tarsus. Both arms of the suture are then passed through the aponeurosis. If surgery is being performed under local anesthesia, the level of aponeurosis can be adjusted by having the patient look in the straight-ahead gaze. If the orbital septum has been opened due to injury, it should not be sutured since this could result in lagophthalmos.  If the laceration is at the level of the lid fold, the eyelid crease is recreated by placing 2-3 sutures. The sutures are passed through the skin muscle layer and include a superficial bite of the levator aponeurosis with 6'0 silk or separately with 5'0 vicryl.

If the lateral canthal tendon (LCT) is found to be severed, it is repaired by passing 4-0 non-absorbable prolene mattress sutures through both ends which should be anchored to the periorbita on the inner aspect of the lateral orbital tubercle (Whitnall's tubercle).( Fig 7). One should aim for overcorrection as the healing tends to shift the canthus inferiorly.


Fig 7 Injury to the lateral canthus


Avulsion of the lid at the medial canthus mostly involves the lower lid. Medial canthal injuries are usually associated with canalicular injury (Fig 8). Intubation of the canaliculus should be performed prior to canthal repair. The surgeon should assess whether the anterior or posterior limb is avulsed. Repair of the posterior limb is more critical to achieve proper lid positioning.
One should assess whether there is soft tissue injury alone or bone is also fractured. In case of soft tissue injury, if both ends are visualised, the distal cut end is identified and sutured to its proximal part. If the proximal portion is not identified , then the horizontal mattress suture is passed through the distal avulsed end and then the needle is passed through the periorbita in the region of posterior lacrimal crest. with 4-0 prolene suture. If there is no periorbita, then microplating is used to fixate medial canthal tendon.  This ensures it is anchored adequately, so that the puncta are turned inwards and ectropion does not result. In case of fracture, it is important to stabilize the fracture and then fixation or transnasal wiring can be performed to repair medial canthal tendon. 


Fig. 8 Injury to medial canthus.

Avulsion of lid at the medial canthus or lacerations in this region will result in complete severance of the canaliculi. Various techniques of surgical repair of canalicular lacerations have been described in the past by various authors. The basic principle in the repair of the lacerated canaliculus is reestablishing of the drainage function. The development of fine sutures, refinement in surgical technique and the use of the microscope have contributed to a better prognosis.

Monocanalicular or bicanalicular stenting may be done. Monocanalicular have the advantage of not disturbing the normal canaliculus. Silicone is the most commonly used material. Mini-Manoka stent is one of the options. However to overcome the cost factor and difficult availability we have been using an alternative technique.
The first step is to identify the two cut ends of the canaliculi. The lateral cut end is  identified by passing a lacrimal probe through the punctum ( Fig 9a). To identify the medial cut end, the wound is examined under magnification, preferably an operating microscope. The tiny opening of the cut canaliculus is rather paler than the surrounding tissues. However, if the cut end is not obvious, it is identified by pooling sterile saline in the wound and then watching for bubbles while injecting air from the upper canaliculus. The use of a pigtail probe to identify the medial end of the lacerated canaliculus should be avoided because of the risk of creating false passages and trauma to the intact canaliculus.
Once the 2 cut ends are identified, a mini-manoka tubing or a 22gauge cannula (venflon) sleeve after removing the sharp tip of the stillete is introduced upto the medial sac wall (Fig 9b). Four pericanalicular bites are then taken with 8-0 vicryl or nylon sutures, two posterior and two anterior.
The lid margin wound is closed by the technique of marginal repair, as described. It is of paramount importance that the MCT should be repaired when it has been disrupted. The silicone tubing or sleeve is left in place for at least 3 months.
When not using a mini-manoka stent, one of the commonest problems encountered is extrusion of the tube from the intubated canaliculus. To retain a monocanalicular stent, fixation sutures (double arm) are passed through the tube and eyelid skin over a peg. These sutures are then carried subcutaneously upwards and medially and tied again over a peg (Fig 9c). These sutures provide an upward and inward traction to the tube preventing its extrusion. Alternatively, to aid in its retention, the silicone tubes may be passed into the nose by using Quickert- Dryden probing system wherein the silicone tube is fixed to a malleable probe which is passed into the inferior meatus through nasolacrirnal duct and recovered from there. The other end of the tube is also passed into the nose from the opposite punctum (bicanalicular intubation). This ensures retention of the probe for the required period of time.

Fig 9c- Fixation of tube by passing double arm prolene through the tube and then through the skin and emerging towards the medial canthus and fixed to the polythene bolster


            In this condition avulsed segments should be found and the avulsed tissue placed in a sterile container containing antibiotic solution and stored in a refrigerator until it can be surgically reimplanted.

Conclusion :

Adequate primary repair of the lid injury gives the most satisfactory results and meticulous repair is mandatory for lid injuries. However where it becomes necessary, a secondary repair gives reasonably good correction, both functional and cosmetic.
