Background
- Pupillary dilation due to blunt eye trauma
- Pupil is poorly reactive to light in both direct and consensual light exposure
- Occurs due to small tears in the ciliary muscles
- May be transient or permanent
- No specific ED management, but requires ophthalmology follow up
- Diagnosis of exclusion!
Clinical Features
Differential Diagnosis
- Physiological Anisocoria
- Intracranial Injury
- Congenital eye defects
- Drugs and toxins
- Third nerve palsy
- Pharmacologic mydriasis
- Injuries associated with blunt eye trauma
Evaluation
- Clinical; rule out intracranial injury
Management
- No specific ED management
Disposition
- If no other injuries/pathology, discharge with optho follow up
