Abstract. Background:Anti-aquaporin 4 antibody(anti-AQP4 antibody)may be present in the serum of patients with myelo-optic neuropathy. There is a possibility that classical multiple sclerosis and myelo-optic neuropathy may be differentiated using anti-AQP4 antibody as a marker. Purpose:To report 5 cases of myelo-optic neuropathy with positive anti-AQP4 antibody. Cases:Sixteen patients were diagnosed with optic neuritis during the past 12 months. Five cases(31%)were positive for anti-AQP4 antibody. All were females aged from 15 to 78 years,average 50 years. All had myelitis involving more than 3 vertebral bones. Optic neuritis was unilateral in all the cases. It became bilateral later in 2 cases. Corrected visual acuity ranged from no light perception to 1.2. Visual field defect included central scotoma,horizontal and temporal hemianopia. Pulsed corticosteroid was effective in 3 cases. Another case improved after additional plasma exchange. Conclusion:Optic neuritis positive for anti-AQP4 antibody is characterized by involvement of females in advanced age,rapid progression,association of myelitis,and improvement after systemic corticosteroid. Coordination between ophthalmologists and neurologists is essential in the diagnosis and treatment.
