[Lacrimal system trauma]

Area of Science:

• Ophthalmology
• Trauma Surgery

Context:

• Canalicular lacerations represent the most frequent injuries within the lacrimal system.
• Demographic data indicate a higher incidence in males, with children being particularly susceptible to this trauma.
• Etiology varies by age, including animal bites in children, altercations in young adults, and falls in the elderly.

Purpose:

• To outline the diagnostic and management principles for canalicular lacerations.
• To emphasize the urgency of surgical intervention for canalicular injuries.
• To differentiate canalicular lacerations from other lacrimal system traumas.

Summary:

• Diagnosis is primarily clinical, confirmed by wound examination or probing, necessitating exclusion of concurrent ocular injuries.
• Surgical management, performed within 48 hours under an operating microscope, involves identifying severed ends, suturing the canaliculus, and considering lacrimal intubation.
• Tetanus prophylaxis is standard, with rabies exposure assessment crucial for animal bites.

Impact:

• Establishes a clear protocol for the timely and effective surgical treatment of canalicular lacerations.
• Highlights the importance of age-specific etiological considerations in patient assessment.
• Reduces the risk of long-term complications associated with untreated or improperly managed lacrimal system injuries.
