Very low urgency
--
Collection of blood in the eye at a subconjunctival level.
In most cases, the cause is unknown. Sometimes it is related to repeated Valsalva manoeuvres (coughing, sneezing, constipation, vomit, etc.), small hits, increases in blood pressure and people following an anti-clotting treatment.
The eye has a red area, usually flat, and generally without any other symptoms. It rarely causes mild discomfort or a foreign body sensation.
Diagnosis is made based on clinical history and a simple physical examination
There is no specific treatment, but if it produces discomfort, artificial tears may be used to reduce it.
