Q: My left eye's retina has a blood leak and the left corner of the eye has some dry blood. My TB test is positive. I need to know more about this eye problem. How do I control this blood from leaking? What kind of a disease is this and is there any treatment?

A:This sounds like subconjunctival haemorrhage i.e. bleeding from superficial part of the eye and not the retina; that is why the eye looks red. This is caused by straining at stool, coughing, sneezing or rubbing the eye, causing minor trauma to the conjunctival blood vessels. This should get better on its own but redness may last for 2-3 weeks. Make sure the eye is not sticky in which case there is secondary infection and needs antibiotic treatment to the affected eye. Also have your blood tested to rule out bleeding or clotting defects. Don't rub the eye also. 99% of the time, this condition is harmless and you need not worry about it.
