In addition, people who wear contact lenses can sometimes develop eye conditions that disrupt the flow of tears, causing inflammation or dryness.Ĭonditions that lead to eye rubbing, such as dry eye syndrome, allergies, and blepharitis, can also be contributing factors. This is because the materials in these lenses start to break down at the edges over time, causing rougher edges. If people use disposable contact lenses for longer than the manufacturer advises, this may also contribute to SCH. This can occur by accident when applying or removing the lens or due to issues with the lens itself, such as surface deposits or defects that may cause friction. As contact lenses have become more popular, the incidence of traumatic SCH has also increased. Foreign objects getting into the eye or harsh rubbing of the eyes are some common examples.Īnother common cause of this type of injury is the use of contact lenses. In this context, the word “traumatic” refers to a physical trauma or injury that affects the eye, causing a small blood vessel to break. Doctors categorize the potential causes of SCH into 2 groups, traumatic and spontaneous. It typically only affects the whites of the eyes, not the iris or pupil. Usually, SCH is painless and does not affect vision, although it may cause a swollen or scratchy feeling. The eye may develop a bruised or yellow appearance as the hemoglobin and other blood components break down.
Faded yellow around pupil Patch#
The main symptom of SCH is a red patch appearing on the white of the eye.Īt first, the patch may be an opaque red with clear borders, before becoming faded and less distinct. This is more likely if the bleeding is persistent or recurs often. Occasionally, SCH can be a sign of an underlying condition. The eye may be red for a while, but this should begin to fade over the next 1-2 weeks. In most cases, the mark on the eye will go away on its own with time, as the blood naturally disperses. Usually, a burst blood vessel in the eye is harmless. Some people have an increased risk of SCH due to a medication or health condition. When a blood vessel breaks, blood pools under the conjunctiva, meaning it is visible but trapped under this layer of tissue. They are protected by the conjunctiva, which is a thin, transparent layer of tissue that covers the eye.
In most cases, it is harmless and goes away on its own.ĭoctors do not know what causes a burst blood vessel in the eye, but it can occur due to the use of contact lenses, an injury, or intense exercise or straining.The sclera has many minute blood vessels that can break and bleed easily. The blood can appear in the whites of the eyes. A Subconjunctival hemorrhage (SCH) is a common type of eye bleed that occurs when a blood vessel is broken.
