are you on any type of blood thinning medicines such as asprin, motrin, naprosyn, aleve, ibuprofen ?
As you know, this is what we call a subconjunctival hemorrhage. While its appearance can be alarming, it isn't a serious problem. It happens when a blood vessel in the conjunctiva (the white part of the eye) breaks and releases blood. This often tends to occur after frequent sneezing, coughing, after rubbing the eye or for no apparent reason. It tends to happen more frequently in people who have high blood pressure or you use blood thinning medicines, such as asprin, motrin, plavix, vitamin e, coumadin, among others. The blood will be reabsorbed into the body within a couple of weeks. There is nothing you can do to make it go away sooner. Usually, there is a sensation of the eye feeling slightly full, or a mild pressure sensation and using artificial tears can help with this symptom. Dont be alarmed by the fact that yours goes around 360 degrees, it is simply due to your use of aleve. If it keeps on recurring in the same eye, you should get your eye examined after it heals to make sure there is not some abnormal blood vessel there that is prone to bleeding but this is very unlikely. I hope you find this helpful, I wish you well, Dr. Stevens
