UKMLA PLAB AMC USMLE Prometric MCQ

Correct Answer: A

Explanation:
Subconjunctival hemorrhage usually occurs secondary to trauma, although the patient may be unaware of the minor trauma involved. In patients receiving anticoagulant medications, spontaneous subconjunctival hemorrhage may be a sign of overdosage. Massive subconjunctival hemorrhage accompanied by proptosis and limited extraocular movements, usually after trauma, signals orbital hemorrhage, which may compromise the optic nerve and retinal circulation.
