To characterize the mean deviation of Humphrey Visual Field (HVF) parametric analysis in patients with NAION.
290 patients with NAION that met our inclusion criteria of were evaluated. A comprehensive ophthalmic evaluation including HVF 24-2 testing in the affected eyes was performed on each patient at the time of NAION diagnosis. All patients were followed for a minimum of two years and were assessed for development of NAION in the contralateral eye. Patients that went on to develop NAION in the contralateral eye underwent repeat HVF 24-2 testing.
At two years, 41 (16%) of patients initially diagnosed with NAION developed NAION in the contralateral eye. The absolute mean deviation was significantly higher in eyes of patients with NAION who went on to develop NAION in the contralateral eye (17.27 dB +/- 7.15 dB; p<0.007 Mann Whitney Rank Sum Test) than in eyes of patients with NAION who did not develop NAION in the contralateral eye (14.68 dB +/- 7.29).
Humphrey visual field testing may play an important role in identifying NAION patients that are susceptible to developing NAION in the contralateral eye.
