What testing is commonly used to evaluate commotio retinae?

• A. Fundus photography
• B. MRI of brain
• C. Visual field testing
• D. Intraocular pressure measurement

Answer: (A)

Documenting retinal changes after blunt trauma is essential, and fundus photography provides a clear, objective image of the retina to capture the whitening characteristic of commotio retinae. It allows baseline documentation and easy comparison over time to monitor for resolution or progression, and it’s quick, noninvasive, and widely available in eye clinics. The other tests don’t directly visualize the retina in this condition: MRI of the brain looks at intracranial structures, visual field testing assesses functional impact rather than structural changes, and intraocular pressure measurement isn’t informative for commotio retinae. Advanced retinal imaging like OCT can offer detailed structural insight, but fundus photography remains the most commonly used initial test to evaluate this condition.
