What Is an Ocular Hemorrhage?

An ocular hemorrhage is bleeding in or around the eye that occurs when fragile blood vessels leak or break. Blood can collect under the conjunctiva, in the anterior chamber as a hyphema, within the vitreous gel, or in the retina or choroid. The appearance ranges from a bright red patch on the white of the eye to dark floaters or sudden vision loss. Causes include trauma, blood vessel disease, blood disorders, and complications of surgery or severe eye strain. Some hemorrhages are harmless and self limited, while others signal serious eye or systemic disease.

Types and Locations of Ocular Hemorrhage

Subconjunctival hemorrhage appears as a flat, bright red patch on the sclera and usually does not affect vision. Hyphema is bleeding in the anterior chamber between the cornea and iris and can raise eye pressure or stain the cornea. Vitreous hemorrhage fills the gel that supports the retina and often causes floaters, haze, or sudden loss of vision. Retinal and choroidal hemorrhages occur within deeper layers and can affect central or peripheral vision depending on location.

Causes and Risk Factors

Common causes include blunt trauma, eye surgery, diabetic retinopathy, retinal vein occlusion, and age related macular degeneration. High blood pressure, blood thinning medications, and clotting disorders increase the likelihood of bleeding. Sudden spikes in pressure from heavy lifting, coughing, or vomiting can trigger subconjunctival hemorrhage in fragile vessels. In children, nonaccidental trauma must be considered when retinal hemorrhages are present. Identifying the source of bleeding helps guide both eye care and systemic evaluation.

Symptoms and Diagnosis

Symptoms range from a red eye without discomfort to floaters, dark curtains, or painful blurred vision. Subconjunctival hemorrhage is often painless and found by chance. Hyphema can cause light sensitivity, eye ache, and reduced vision. Vitreous or retinal hemorrhage usually leads to new floaters, haze, or field defects. Diagnosis is based on slit lamp and dilated fundus examination, sometimes supported by ultrasound or imaging when the view is blocked.

Treatment and Prognosis

Treatment depends on cause, location, and severity. Subconjunctival hemorrhages usually need only observation and reassurance. Hyphemas require rest, head elevation, and careful pressure monitoring, with surgery in some cases. Vitreous and retinal hemorrhages are managed by treating the underlying retinal disease and, when needed, vitrectomy to clear blood. Prognosis ranges from full recovery to permanent vision loss when the macula or optic nerve is damaged.

FAQs About Ocular Hemorrhage

Is every red eye a serious hemorrhage?

No, many red eyes are due to minor surface bleeding or irritation, but sudden changes still deserve evaluation.

Can an ocular hemorrhage clear on its own?

Subconjunctival and some small vitreous or retinal hemorrhages can clear gradually as the body absorbs the blood.

Should I stop blood thinners if I have an eye hemorrhage?

Never stop systemic medication without medical advice; your eye doctor and primary doctor should decide together.

Can rubbing the eye cause bleeding?

Forceful rubbing can break fragile vessels on the surface and should be avoided, especially in people with thin vessels or blood disorders.
