Electrophysiological and Structural Changes in Chinese Patients with LHON

Figure 4

Electrophysiological recordings obtained from patient 1 in Table 1. (a)PERG, (b)PVEP, (c) mfERG at acute stage, (d) PERG, (e) PVEP, (f) mfERG at chronic stage, (g) PERG, (h) PVEP, and (i) mfERG of normal control eye. The N95 component amplitude reduced both in the acute and chronic stage. The amplitude density of inner rings of the MFERG reduced both in the acute and chronic stages. BCVA: 6/120 (acute stage); 6/300 (chronic stage). PERG recordings were reproducible.
