Abstract:
Objective To explore the characteristic and the rule of flash-visual evoked potentials (F-VEP) of SD rats after optic nerve injury in different grades. Methods By using APS-2000 multifunctional electric physiological instrument, changes in F-VEP were observed in normal optic nerve and injured optic nerve (crushed in 3 grades) in rats. The latency and amplitude of F-VEP wave, were recorded and statistically. Results The F-VEP wave was reliably displayed with characteristic curve. The L5b was(53.67?3.12)ms and A5 was(17.83?5.91)?v. The latency of F-VEP in rats with optic nerve injury in different grades showed a significant prolongation, and the amplitude showed a significant decrease compared with normal rats (P
