Blunt trauma
Ocular Trauma
Key Points
- •Blunt trauma accounts for 60% of all ocular injuries and is the most common cause of traumatic eye damage - always perform a systematic anterior-to-posterior examination
- •BETT classification divides closed globe injuries into contusion and lamellar laceration; zones I–III localise the damage from surface to posterior segment
- •360° subconjunctival haemorrhage mandates exclusion of occult scleral rupture before labelling as closed globe injury
- •Angle recession ≥180° predicts ~10% risk of late-onset glaucoma requiring lifelong IOP monitoring
- •Rosette cataract (stellate PSC opacity) is pathognomonic of blunt ocular trauma - no other condition produces this pattern
