Bilateral blindness due to trauma in Cambodia

Area of Science:

• Ophthalmology
• Public Health
• Trauma Surgery

Background:

• Ocular trauma is a leading cause of monocular blindness globally.
• It is typically not a major cause of bilateral blindness.
• Prevention is key in developing nations due to surgical access challenges.

Observation:

• A study in northwest Cambodia examined 453 bilaterally blind individuals.
• 17% (4%) were blind due to trauma, predominantly young males (15-35 years).
• 14 cases resulted from bilateral penetrating injuries caused by landmine explosions.

Findings:

• Penetrating ocular trauma is a significant cause of bilateral blindness in Cambodia.
• Landmine explosions are the primary cause, affecting young males.
• Other major causes of blindness include cataract, glaucoma, and corneal scarring.

Implications:

• Urgent need for landmine clearance in Cambodia, estimated to take centuries.
• Highlights the severe impact of landmine-related injuries on young populations.
• Underscores the importance of targeted prevention strategies for ocular trauma in conflict zones.
