Ophthalmology · Ocular trauma: canalicular laceration
Sample itemA child with a dog bite has a laceration of the medial lower lid involving the canaliculus. What is the ideal management?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Early primary repair with silicone intubation
Canalicular lacerations should be repaired early with intubation by a silicone stent to maintain patency and avoid epiphora. Skin sutures alone leave a severed duct. Dacryocystorhinostomy and plugs are not primary treatments.
Option by option
A. Early primary repair with silicone intubation (correct)
Correct. Early repair with a silicone stent preserves tear drainage.
B. Delayed dacryocystorhinostomy
Dacryocystorhinostomy is a secondary procedure for sac or duct obstruction.
C. Simple skin suturing only
Skin suturing alone leaves the canaliculus severed and causes epiphora.
D. Punctal plug insertion
A plug blocks drainage and is used for dry eye.
