Overview

Sometimes small blood vessels on the white of the eye can break, causing a spot or speck of blood. This is called a subconjunctival hemorrhage. The redness may look alarming, especially if the spot is large. These hemorrhages are very common. If there is no pain or change in your vision, no treatment is needed. The blood will slowly go away on its own in 2 to 3 weeks.

Symptoms

A subconjunctival hemorrhage causes a spot, or speck, of blood to appear in the white of your eye. The red area can be quite large, and gravity may cause it to spread to the lower portion of the eye. As it heals, the hemorrhage acts like a bruise and will fade and turn yellow. These hemorrhages are harmless and do not affect your vision. 

Watch closely for changes in your health and be sure to contact us if your eye color does not steadily return to normal, or if the blood has not gone away after 2 to 3 weeks. If you develop bruising or bleeding elsewhere, such as the gums, or if you have nosebleeds, contact your personal physician.

Contact us immediately if:
  • You see blood over the black part of your eye (pupil).
  • You have any changes or problems in your vision.
  • You have any pain in your eye.
  • You have any discharge from your eye.

Causes

We do not always know what causes a subconjunctival hemorrhage.  It can develop as a result of a strong sneeze or cough, or from vomiting, straining (due to constipation), high blood pressure, or bending over. Any kind of trauma to the eye, even rubbing it, can also cause this type of hemorrhage. People taking blood thinners like aspirin or coumadin can develop these benign hemorrhages more easily. However, developing a subconjunctival hemorrhage is not a reason to stop taking coumadin or aspirin that has been prescribed by your doctor.

Diagnosis

In most cases, no exam is needed. However, if your medical history indicates that you have risk factors for developing bleeding problems, your personal physician may take your blood pressure and/or order a blood test to rule out other conditions.

Treatments

These hemorrhages are painless and harmless and will go away in several weeks without treatment. If you have mild eye irritation, over-the-counter artificial tears may be helpful. It is important to watch for changes in your eye. It is normal for the red spot on your eyeball to change color as it heals. Just like a bruise on your skin, it may change from red to brown to purple and then to yellow.

If you take aspirin regularly, we recommend that you ask your personal physician if you should continue to take it, as it may exacerbate bleeding problems. Use acetaminophen (Tylenol) if you need pain relief for another condition or an injury. 

Your Care with Me

A subconjunctival hemorrhage will usually go away on its own in 2 to 3 weeks. However, if it has not gone away after 2 to 3 weeks, or you develop bruising or bleeding elsewhere or other symptoms that concern you, your first contact will typically be with your personal physician, who will evaluate your health and symptoms.

If specialty care is needed, your personal physician will facilitate the process of scheduling an appointment in my department. If appropriate, she or he might call me or one of my colleagues while you are in the office so we can all discuss your care together. If we decide you need an appointment with me after that discussion, we can often schedule it the same day or soon thereafter.

Your first appointment is likely to take at least 1 hour and possibly longer. During your office visit, we will discuss your medical and family history and I will perform a comprehensive eye exam and some diagnostic tests.

I may administer eye drops to dilate your pupils so that I can clearly see the structures of your eyes. Your pupils will remain dilated for several hours, so you may wish to bring someone who can drive you home after your exam.

I will explain the findings of your exam and answer any questions or concerns you may have. If you notice any new changes, please let me know.

If we decide that you need further evaluation, or further treatment, I will discuss the treatment options that are available, and together we will create a treatment plan that is right for you.

If you need to talk with me after your visit or procedure, please call my office. You can also e-mail me with nonurgent issues from this website whenever it is convenient for you.

If you have urgent concerns or issues while my office is closed, or need general medical advice, you can call the Appointment and Advice line, available 24 hours a day, 7 days a week. You will be connected with a nurse who can give you immediate advice.

If you are experiencing a serious problem or an emergency, call 911 or go to the nearest Emergency Room when the clinic is not open.

Coordinating Your Care

Having all of our Kaiser Permanente departments located together or nearby, including pharmacy, laboratory, radiology, and health education, makes getting your care easier for you.

Another major benefit is our comprehensive electronic medical record system, which allows all of the doctors and clinicians involved in your care to stay connected on your health status and collaborate with each other as appropriate.

When every member of the health care team is aware of all aspects of your condition, care is safer and more effective.

If you come to an office visit
  • At the beginning of your visit, you will receive information about when you are due for your next test, screening, or immunization. We can discuss and schedule any preventive tests that you need. 
  • At the end of your visit, you may receive a document called the "After Visit Summary" that will summarize the issues we discussed during your visit. You can refer to it if you forget what we discussed. You can also view it online under Past Visits.
  • To help you prepare for your visit, please see additional details under Office Visit. 
If I prescribe medications

We will work together to monitor and assess how your medications are working and make adjustments over time. Prescriptions can be filled at any Kaiser Permanente pharmacy. Just let me know which pharmacy works best for you, and I will send the prescription electronically in advance of your arrival at the pharmacy.

If refills are needed in the future, you can:
  • Order them online or by phone. Order future refills from my home page or by phone using the pharmacy refill number on your prescription label.
  • Have them delivered to you by mail at no extra cost. Or you can pick up your medications at the pharmacy. If no refills remain when you place your order, the pharmacy will contact me regarding your prescription.
If lab testing or imaging is needed

For lab tests, I will use our electronic medical record system to send the requisition to the Kaiser Permanente laboratory of your choice. For imaging procedures, we will schedule an appointment with the Radiology department. When the results are ready, I will contact you with your results by letter, secure e-mail message, or phone. In addition, you can view most of your laboratory results online, along with any comments that I have attached to explain them.

If I refer you to another specialty colleague

If we decide together that your condition would also benefit from the care of other types of specialists, our staff will help arrange the appointment(s) with one or more of my specialty colleagues.

If surgery or a procedure is a treatment option

I will recommend you review educational information and tools to help you prepare for your procedure or surgery. The information will often help you decide whether surgery is right for you. If you decide to have a surgery or procedure, the information will provide details about how to prepare and what to expect.

If we proceed with surgery, I will have my Surgery Scheduler contact you to determine a surgery date and provide you with additional instructions regarding your procedure. Once your surgery is scheduled, a medical colleague of mine will contact you to conduct a preoperative medical evaluation that will assure that you are properly prepared for your surgery.
