Very low urgency
--
It is a build up of blood on the eye, below the conjunctiva.
In most cases, there is no known cause. Sometimes it is related to repeated Valsalva maneuvers (cough, sneezing, constipation, vomiting, etc.), to small hits, increases in blood pressure and people who are following anti-clotting treatment.
The eye has a red area, usually flat, and generally without any other symptoms. Light discomfort or feeling of a foreign body are seldom found.
Diagnosis is reached through clinical history and basic physical examination.
There is no specific treatment. If the condition produces any discomfort, artificial tears may be used to reduce it.
