title: Bilateral permanent concentric visual field defect secondary to severe pre-eclampsia.
abstract: OBJECTIVE
  To present a patient with bilateral permanent concentric visual field defect secondary to severe pre-eclampsia.
  
  
  METHODS
  A forty-year-old woman presented to the ophthalmology department with partial visual field defect affecting her both eyes. She gave a history of emergent uterine curettage for severe uncontrolled pre-eclampsia in the 24th week of her second gestation which was 10 years before. Two days after the procedure, the patient complained of peripheral visual field defect in her both eyes which persisted until her last presentation. Her best-corrected visual acuity, color vision, intraocular pressures, and anterior segment examination findings were normal bilaterally. Fundus examination showed a normal optic nerve head with reduction of arteriole to vein ratio in both eyes. Humphrey Field Analyzer revealed a bilateral concentric visual field defect. Visual Evoked Potentials (VEP) and Electroretinography (ERG) were within normal limits in both eyes. Cranial magnetic resonance imaging (MRI) was normal.
  
  
  CONCLUSIONS
  Herein, we presented a case of permanent concentric visual field defect which developed as a complication of severe uncontrolled pre-eclampsia. To the best of our knowledge; such a case has not been reported to date.
