Blood in eye. Blood over the white part of the eye is called subconjunctival hemorrhage-- it will resolve in 2-4 weeks unless you are on a blood thinner. If it does not get better, or if blood is inside the eye, consult your local ophthalmologist.
Depends on location. If the blood is in the posterior segment of the eye, ie the vitrous which is the gel in the back of the eye, most retina specialists would wait. If the their is no spontaneous resolution, they may remove it surgically. If the bleeding is under the retina in the center of vision called macula, the decision to remove the blood surgically may be earlier than other locations.
Blood inside the eye. Bleeding can occur from trauma, vascular events and certain hereditary illnesses that affect the eyes. Free blood in the eye drops the vision and bleeding can also occur in the substance of the retina with variable effect on the vision (e.g. In diabetes). Any bleeding in the eye needs immediate evaluation by your ophthalmolgist.
Can be serious. You may experience blurred vision that is worse when you are active. The symptoms improve if you sleep sitting up and are not moving around. The causes vary from blunt trauma (hyphema) which leaves blood in the front of the eye, to vitreous hemorrhage, also sometimes caused by trauma but also can be spontaneous in diabetes.
Both eyes or one? If both eyes spontaneously develop this problem it could suggest an underlying and serious systemic condition. Some viruses are known to cause a hemorrhagic conjunctivitis also. Blisters suggest an immunologic reaction as can be seen in steven's johnson syndrome. I would recommend seeing a doctor immediately!
See your eye md. You need a detailed exam to evaluate cause.
See Ophthalmologist. Blisters and cysts as well as blood are not normal. See your ophthalmologist.
Blood in eye. Blood over the white part of the eye is called subconj heme-- this will resolve in 2-4 weeks. If it does not, or if is inside the eye, then consult your local ophthalmologist.
Nothing or lots. If by blood in your eye you mean that it looks blood red, but no pain or discharge, this is just like a bruise, and will clear on its own with time. If you have blood inside your eye from bleeding from medical issues, then you need to see an ophthalmologist soon to determine the cause and seek treatment if needed.
Blood in the eye. Blood in the eye may mean different problems. Externally on eyeball surface (white part) may be a small bruise generally self limited and benign and the result of rubbing the eyelids. Internal blood (inside the eyeball) is almost always abnormal.
Many things. You need to see an eye doctor to evaluate this further, especially if the problem persists.
Where? If you mean on the white part and there is little or no pain, yes, that is very common. It is no more serious than a bruise to your thigh and will go away without any overt treatment. It is more common in those who need blood thinners--but do not stop them. The most common cause is stifling a sneeze--let her rip. Don't "play" with it. Don't hold your breath with exertion of any kind.
Diabetic retinopathy. Diabetic retinopathy with vitreous hemorrhage- common.
Too vague. Subconj blood has no symptoms. Vitreous in blood can cause profound vision loss.
Floaters. The most common symptom of blood in the back of the eye is new floaters and vision loss. See your ophthalmologist for an examination immediately.
Blood in the eye. You can also see red spots or black spots or could have blocked field of vision or pain in some cases in the eyes.
Depends location. External=subconjunctival hemorrhage In anterior chamber= hyphema back of eye= retinal hemorrhage.
Blood in the eye. Blood in the eye can mean several things. If the eye has recently suffered trauma, a hyphema may result-- this needs to be followed carefully for a week or more, since it may result in increased pressure in the eye or decreased vision. Blood on the surface of the eye is likely a subconj heme-- this will resolve in 2-4 weeks by itself. Blood in the retina needs follow-up locally.
Blood in eye. You would have to be more specific about where the blood is located and how it got there. If it was through an injury the eye has to be examined carefully to see if there are internal injuries to the eye. But the term blood in the eye is too vague to give a good answer.
Hyphema. Blood in the eye or hyphema, usually comes from trauma to the eye. If there is no ocular problem resulting, it should not cause any general health problems.
Peyote. Peyote is an hallucinogenic drug and has no specific eye effect, the subconjunctival hemorrhage you describe is unrelated and may be due to trauma with rubbing your eyes, coughing, sneezing or straining. And should resolve within a week or two.
Likely coincidental. Peyote has psychoactive effects primarily affecting the central nervous system. Eye effects are limited to visual hallucinations and dilated pupils. There are no direct structural effects on the eye. What you are noticing in your eye is likely a sub-conjunctival hemorrhage, which is associated with coughing, sneezing, straining or even rigorous eye rubbing.
