Abstract Purpose:To report a case of loss of light perception in the right eye(RE)associated with anti-neutrophil cytoplasmic antibody(ANCA)-related hypertrophic pachymeningitis during the course of microscopic polyangiitis(MPA).

Case:An 82-year-old woman, diagnosed with MPA after a renal biopsy 9 years ago due to high myeloperoxidase(MPO)-ANCA levels, has been treated for MPO-ANCA positive MPA. The patient presented to our hospital with decreased visual acuity in the RE one month before the presentation.

Findings and clinical courses:The corrected visual acuity was no light perception in the RE and 1.2 in the left eye. Relative afferent pupillary defect was detected in the RE. Funduscopy and fluorescein angiography showed no abnormal findings. In a blood test, serum MPO-ANCA levels were within normal limits and C-reactive protein was negative. Brain contrast-enhanced magnetic resonance imaging revealed an enhanced lesion in the right orbital apex in addition to findings of hypertrophic pachymeningitis, suggesting that orbital apex inflammation may lead to loss of visual acuity. After two courses of steroid semi-pulse therapy, her corrected visual acuity improved to 0.7 in the RE. Goldmann perimetry revealed only about 15 degree central scotoma with I 3e to I 4e and recovery of peripheral visual field in the RE.

Conclusions:ANCA-related hypertrophic pachymeningitis that causes severe loss of visual acuity can occur during the course of MPA, even though serum MPO-ANCA is within normal limits.
