Subconjunctival Hemorrhage: Causes, Symptoms, Treatment, and Prevention

  • Home

What is Subconjunctival Hemorrhage?

Subconjunctival hemorrhage is a common eye condition. It happens when a small blood vessel breaks just under the clear surface of your eye. As a result, you may notice a bright red spot in your eye. Although it can look scary, it is usually harmless. Most people do not feel pain or vision changes. However, seeing blood in your eye can be alarming. This condition is not the same as bleeding inside the eye. According to the CDC, most cases resolve on their own within two weeks.

Causes of Subconjunctival Hemorrhage

There are many reasons why a subconjunctival hemorrhage can occur. Often, it happens without any clear cause. Still, some common causes include:

  • Sudden coughing or sneezing
  • Heavy lifting or straining
  • Rubbing your eyes too hard
  • Minor eye injuries
  • High blood pressure
  • Taking blood thinners or aspirin
  • Bleeding disorders
  • Eye infections

    • Sometimes, even simple actions like laughing or vomiting can cause a blood vessel to break. In rare cases, eye surgery or trauma may lead to this condition. If you have frequent episodes, it is wise to talk to your doctor.

    Symptoms and When to Seek Help

    Usually, the main symptom is a red spot in the white part of your eye. Most people do not feel pain or discomfort. In addition, vision stays normal. However, you may notice mild irritation or a scratchy feeling. The red area may spread before it fades. Although it looks serious, it rarely causes harm.

    Still, you should seek medical help if you notice:

  • Pain in the eye
  • Changes in vision
  • Blood in both eyes at once
  • Frequent or repeated bleeding
  • Bleeding after an eye injury
  • Other signs of bleeding, such as nosebleeds or easy bruising

    • For most people, a subconjunctival hemorrhage is not dangerous. But, it is always better to check with an eye specialist if you are unsure.

    Diagnosis and Medical Evaluation

    Doctors can usually diagnose a subconjunctival hemorrhage by looking at your eye. They may ask about your health history and recent activities. Sometimes, they will check your blood pressure. If you have frequent episodes, your doctor may order blood tests. These tests can check for bleeding problems or other health issues. In rare cases, further eye exams are needed. According to the American Academy of Ophthalmology, most cases do not need special tests.

    Treatment Options

    Most cases of subconjunctival hemorrhage do not need treatment. The red spot usually fades within one to two weeks. Your body absorbs the blood naturally. While you wait, you can:

  • Use artificial tears to ease irritation
  • Avoid rubbing your eyes
  • Rest and avoid heavy lifting

    • Doctors do not recommend using eye drops with steroids or antibiotics unless there is an infection. If you take blood thinners, do not stop them without talking to your doctor. In rare cases, if the bleeding is due to an injury or health problem, your doctor will treat the underlying cause.

    Prevention Tips and Lifestyle Guidance

    Although you cannot always prevent a subconjunctival hemorrhage, you can lower your risk. Here are some helpful tips:

  • Manage your blood pressure
  • Be gentle when rubbing your eyes
  • Wear protective eyewear during sports or risky activities
  • Control allergies to reduce eye rubbing
  • Follow your doctor’s advice if you take blood thinners
  • Eat a healthy diet to support blood vessel health

    • Additionally, regular eye check-ups can help catch any problems early. If you notice any changes, seek advice from an eye specialist.
