A case report of tuberculous meningitis resulting in irreversible visual impairment due to delayed diagnosis.

Key Clinical Message: Prompt diagnosis of tuberculous meningitis (TBM) is crucial to prevent severe complications like cranial nerve involvement and irreversible visual impairment. Early suspicion and intervention are essential, especially in tuberculosis-endemic regions. Rapid initiation of anti-tuberculosis therapy and vigilant monitoring for complications, such as hydrocephalus, improve patient outcomes and prevent long-term disabilities.
