Subconjunctival hemorrhage is a condition where blood collects under the clear membrane covering the white part of the eye (the conjunctiva). It is often caused by minor trauma or exertion, but can also occur due to high blood pressure or certain medications. The symptoms include seeing a red patch under the eye. It is usually painless and does not require medical treatment unless it worsens. If symptoms persist or worsen, it is advisable to seek care from a qualified clinician. The condition is confirmed through a clinical examination, and treatment is determined by a clinician after confirming the diagnosis. There are no specific dosing instructions provided.
