Hello Sir, My cousin was diagnosed with brain TB some 2 months back.She was admitted in Alleppey Medical hospital and her condition worsened over the period of time. TB tests were conducted with no positive result. Thereafter, she was moved to Chitra Medical Hospital, Trivandrum and her samples were sent to NIMHANS for further study. Meanwhile, this period my cousin was losing her vision. A brain surgery was carried out and it was found that the vein supporting the eye sight was blocked and it was infected. The doctors are saying that she will lose her eyesight in a few months or so because of the infection. We really dont know if it s TB.Is there anything which we could do to retain her eyesight?
