Isolated cortical blindness without simultaneous neurological involvement in progressive multifocal leukoencephalopathy in a patient with human immune deficiency virus infection.

BACKGROUND

This is a case report of cortical blindness in a HIV-positive patient with progressive multifocal leukoencephalopathy (PML) without any other associated neurological dysfunction.

FINDINGS: Young HIV-positive patient presented to us with sudden profound visual loss. On examination and further investigation, we have diagnosed cortical blindness without any other focal neurological deficit due to PML.

CONCLUSION

Our case highlights the fact that PML needs to be suspected in patients with HIV, presenting with cortical blindness even without any other focal neurological defect.
