Congestion of the eye with blood clots, the medical term for subconjunctival hemorrhage, is caused mainly by the rupture of small blood vessels under the conjunctival surface of the eye, especially capillaries that bleed and collect under the conjunctiva. The shape of subconjunctival hemorrhage is different and is related to the amount of bleeding. The color can vary from bright red to purplish red, if the bleeding is relatively small, it appears bright red, if the bleeding is large, it can appear purplish red. Subconjunctival hemorrhage mostly occurs in the lid fissure area and tends to move toward the corneal limbus over time. The duration of the disease can be completely absorbed in 20 days to a month.
