Pitfalls in Visual Field Testing

Bitemporal hemianopias often induce referrals to neuro-ophthalmology clinics to investigate for pituitary fossa masses. A 28-year-old woman presented with headaches and a visual field test performed without refractive correction found a bitemporal hemianopia, though this did not strictly obey the vertical midline (Figures 1 and 2). Her refraction was: −5.5DS/−2.75DCx152 OD and −6.00DS/−2.50DCx55 Neuro-ophthalmology, 34(2), 104–107, 2010 Copyright © 2010 Informa Healthcare USA, Inc.
