###Human: What is the black line in eye obstructing the vision? ###Assistant: Hi. You seem to have vasculitis which is inflammation of blood vessels in your eye which makes your blood vessels leaky. Injections of an anti-VEGF compound are indicated in this but before this, you need laser therapy in your eye along with a course of steroids. You need to undergo fundus fluorescein angiography to locate the area of leaky vessels and we have to laser it. You also need to get a blood investigation to rule out infections like tuberculosis. After that is ruled out, we have to start steroids. Anti-VEGF injections come after that. Kindly do not delay it if this process continues. The visual prognosis becomes poorer if not done in time. You may need surgery which would be more costly.
