Concurrent Tuberculous Optic Neuritis and Optic Perineuritis in a Patient With Human Immunodeficiency Virus (HIV)

Concurrent tuberculous optic neuritis (ON) and optic perineuritis (OPN) in a patient with human immunodeficiency virus (HIV) is extremely rare. HIV-induced progressive CD4 depletion is associated with an increased risk of tuberculosis (TB), disseminated TB, and death. Early detection and initiation of anti-TB therapy with corticosteroid commencement helps in achieving better visual outcomes. Interestingly, we report a case of concurrent ON and OPN in a patient with HIV-TB co-infection. A 29-year-old lady, a prisoner, with newly diagnosed treatment-naive HIV, presented with acute-onset reduced vision in the left eye for 10 days. It was associated with pain in eye movement and headache. The patient was known to be a drug abuser since the age of 19 years and was a sexual worker. Her CD4 count was 292 cells/mm
