A subconjunctival hemorrhage occurs when a blood vessel breaks under the conjunctiva, the clear membrane that covers the white part of the eye. This condition can cause a bright red patch to appear on the white of the eye.
Subconjunctival hemorrhages can occur spontaneously or may result from minor trauma, such as coughing, sneezing, or rubbing the eyes. They can also be associated with conditions that affect blood clotting, such as hypertension or blood-thinning medications.
Subconjunctival hemorrhages typically resolve on their own within a week or two without treatment. However, if you experience any pain or changes in vision, it's important to seek medical attention to rule out any underlying eye conditions.
