Unusual fundus examination findings in tuberculous meningitis.

Vision impairment is one of the devastating complications of central nervous system tuberculosis (CNS TB). Optic atrophy is a sequelae of various forms of CNS TB which, ultimately, is responsible for vision impairment. It is usually the secondary optic atrophy which occurs in CNS TB. In this case report, we present two cases of CNS tuberculosis developing primary optic atrophy, which is infrequently reported. The relevant pathophysiology and causes of vision impairment in CNS TB are also discussed.
