EXTENDED REPORT Frequency doubling technology perimetry in non-arteritic ischaemic optic neuropathy with altitudinal defects

Abstract

Aim: To determine if frequency doubling technology perimetry (FDT) is more sensitive to optic nerve injury in non-arteritic ischaemic optic neuropathy (NAION) than standard automated perimetry (SAP). Methods: Charts from 18 patients (20 eyes) with NAION with altitudinal defects who underwent a complete neuro-ophthalmic examination, SAP, and FDT were… (More)
