When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Subconjunctival Hemorrhage.
Several factors can cause the delicate blood vessels beneath the conjunctiva to rupture.
Several factors can cause the delicate blood vessels beneath the conjunctiva to rupture. Sometimes the cause is obvious, like rubbing your eyes vigorously, having a severe coughing fit, or straining during heavy lifting. These activities increase pressure in the blood vessels, making them more likely to break. Even something as simple as a powerful sneeze can create enough pressure to cause bleeding.
Age-related changes make blood vessel walls more fragile and prone to breaking.
Age-related changes make blood vessel walls more fragile and prone to breaking. As we get older, the tiny capillaries in our eyes become more delicate, and even minor pressure changes can cause them to rupture. This explains why subconjunctival hemorrhages become more frequent with advancing age, even without any obvious trigger.
Certain medical conditions and medications can increase your risk.
Certain medical conditions and medications can increase your risk. Blood thinners like warfarin or aspirin make bleeding more likely when vessels do break. High blood pressure, diabetes, and bleeding disorders can also contribute. Eye trauma, even minor injuries from contact lens insertion or eye rubbing, represents another common cause. Occasionally, no clear cause can be identified, and the hemorrhage occurs spontaneously.
Risk Factors
- Age over 50 years
- Taking blood-thinning medications
- High blood pressure
- Diabetes mellitus
- Frequent eye rubbing or touching
- Severe coughing or sneezing fits
- Heavy lifting or straining
- Contact lens wear
- Recent eye surgery or injury
- Bleeding disorders or clotting problems
Diagnosis
How healthcare professionals diagnose Subconjunctival Hemorrhage:
- 1
Diagnosing a subconjunctival hemorrhage is usually straightforward and requires no special tests.
Diagnosing a subconjunctival hemorrhage is usually straightforward and requires no special tests. Your doctor can typically identify the condition just by looking at your eye during a routine examination. The bright red appearance against the white background of the eye creates a distinctive pattern that's easy to recognize. Your doctor will ask about recent activities, medications, and any symptoms you've experienced.

A more thorough evaluation may be needed if you have recurrent hemorrhages or other concerning symptoms.
A more thorough evaluation may be needed if you have recurrent hemorrhages or other concerning symptoms. Your doctor might check your blood pressure, review your medications, and ask about bleeding elsewhere in your body. They'll also examine both eyes carefully to rule out other conditions that might cause redness, such as conjunctivitis or more serious eye problems.

Additional testing becomes necessary only in specific situations.
Additional testing becomes necessary only in specific situations. If you have frequent subconjunctival hemorrhages, blood tests might check for clotting disorders. If the hemorrhage occurred after trauma, your doctor may examine your eye more thoroughly to ensure no other structures were damaged. Most people with isolated, painless subconjunctival hemorrhages need no testing beyond a basic eye examination.
Complications
- True complications from subconjunctival hemorrhages are extremely rare.
- The vast majority of these hemorrhages resolve completely without any lasting effects on vision or eye health.
- The blood is reabsorbed naturally, leaving no permanent staining or damage to the eye structures.
- Even large hemorrhages that cover significant portions of the white part of the eye typically heal without problems.
- The main concern isn't the hemorrhage itself, but rather what might have caused it.
- Recurrent subconjunctival hemorrhages could signal underlying conditions like uncontrolled high blood pressure, bleeding disorders, or blood clotting problems that need medical attention.
- Very rarely, frequent hemorrhages might indicate a serious condition affecting blood vessels or clotting mechanisms throughout the body.
Prevention
- Preventing subconjunctival hemorrhages focuses on avoiding activities and situations that increase eye pressure.
- Be gentle when rubbing your eyes - if they feel itchy or irritated, use artificial tears instead of rubbing.
- When you need to rub your eyes, do so very gently with clean hands.
- If you have allergies that make your eyes itchy, treating the underlying allergies can reduce the urge to rub.
- Managing underlying health conditions plays a vital role in prevention.
- Keep blood pressure well-controlled through medication, diet, and exercise as recommended by your doctor.
- If you take blood thinners, follow your prescribed dosage carefully and report any unusual bleeding to your healthcare provider.
- Contact lens wearers should follow proper insertion and removal techniques, ensuring their hands are clean and being gentle with their eyes.
- While you can't prevent all subconjunctival hemorrhages, protecting your eyes from injury reduces risk.
- Wear appropriate eye protection during sports, yard work, or any activity where debris might fly toward your face.
- If you have a severe cough, try to control the intensity when possible, and consider seeking treatment for persistent coughing that might be related to an underlying condition.
The good news about subconjunctival hemorrhages is that they typically require no treatment at all.
The good news about subconjunctival hemorrhages is that they typically require no treatment at all. Your body will naturally reabsorb the blood over one to two weeks, much like how a skin bruise fades away. During this time, the red color may change slightly as the blood breaks down, but this is completely normal. Artificial tears can provide relief if you experience mild irritation, but avoid eye drops that promise to reduce redness, as these can sometimes worsen the condition.
Managing any underlying conditions represents the most important aspect of treatment.
Managing any underlying conditions represents the most important aspect of treatment. If high blood pressure contributed to the hemorrhage, working with your doctor to control your blood pressure becomes crucial. People taking blood thinners should continue their medications as prescribed - stopping these medications without medical guidance can be dangerous. Your doctor will help balance the benefits and risks of any blood-thinning therapy.
Avoid rubbing or touching your eye while it heals, as this can potentially worsen the bleeding or introduce bacteria.
Avoid rubbing or touching your eye while it heals, as this can potentially worsen the bleeding or introduce bacteria. Normal activities like reading, watching television, and using computers are perfectly safe and won't interfere with healing. Contact lens wearers might want to switch to glasses temporarily if the lens feels uncomfortable against the slightly raised blood patch.
Several warning signs warrant immediate medical attention.
Several warning signs warrant immediate medical attention. Seek prompt care if you experience pain, vision changes, light sensitivity, or discharge from the eye. Multiple hemorrhages in both eyes, especially if accompanied by unusual bleeding elsewhere in your body, should be evaluated quickly. If the hemorrhage occurred after significant eye trauma, don't wait to have it examined, as other eye structures might be damaged.
Living With Subconjunctival Hemorrhage
Living with a subconjunctival hemorrhage requires patience more than anything else. The bright red appearance can be socially awkward, as people may assume you have a serious eye infection or injury. Explaining that it's harmless and temporary can help put others at ease. The hemorrhage won't affect your ability to work, drive, or participate in normal activities, so there's no need to alter your routine.
