title: Optic disc asymmetry: normal tension glaucoma or a space-occupying lesion?
abstract: Optic disc asymmetry is a common finding. In the majority of cases automated visual fields are normal. However, in a minority, a visual field defect may lead to a diagnosis of normal tension glaucoma. Rarely, the optic discs and visual field deteriorate irrespective of the normal or reduced intraocular pressure.
