Neurobrucellosis Manifesting as an Altitudinal Visual Field Defect

Area of Science:

• Ophthalmology
• Infectious Diseases
• Neurology

Background:

• Brucellosis is a zoonotic infection with diverse systemic and neurological effects.
• Ocular manifestations of brucellosis, including optic neuritis, are significant but not fully understood.
• Consumption of unpasteurised dairy products is a primary transmission route.

Observation:

• A case report details a 43-year-old male with unilateral optic neuritis and altitudinal visual field defect due to Brucella infection.
• The patient presented with visual impairment secondary to neurobrucellosis.

Findings:

• Anti-Brucella and corticosteroid therapy led to visual acuity improvement within six months.
• Despite treatment, the altitudinal visual field defect showed persistence, indicating potential long-term sequelae.
• This case highlights the CNS and ocular impact of Brucella.

Implications:

• Early diagnosis and prompt treatment of brucellosis are crucial to prevent severe ocular and neurological complications.
• Further research is needed to elucidate the mechanisms of ocular involvement in Brucella infections.
• Understanding ocular brucellosis is vital for patient management in endemic regions.
