Which symptom is associated with retinal detachment after blunt trauma?

• A. Double vision.
• B. Flashing lights.
• C. Loss of color vision.
• D. Painful redness.

Answer: (B)

Retinal detachment after trauma typically presents with photopsia—sudden flashing lights in the vision—often along with new floaters. This occurs when the retina is pulled away from its proper position, triggering brief light phenomena as the retina is stimulated. The eye is usually not painful in detachment, so painful redness points to other injuries or inflammation. Double vision suggests involvement of ocular muscles or nerves, not detachment, and loss of color vision points to optic nerve issues. That combination makes flashing lights the symptom most associated with retinal detachment after blunt trauma.
