Changes of electroretinogram in temporary traumatic ocular hypotention / 中华眼底病杂志

ABSTRACT

Objective To observe the changes of electroretinogram(ERG) in temporary traumatic ocular hypotension and to detect the possible mechanism. Method The rabbit model with ocular hypotenstion was made. At the 2nd, 4th, 8th, 16th week after trauma, the ocular tension and ERG was examined. Result Amplitude of b wave in treated group was 2.5 times as high as that in the control at the 2nd week after trauma, and then decrease to 1.5 times as high as that in the control at the 16th week. Conclution Higher amplitude of b-wave of ERG in rabbit with ocular hypotension may be related to blood circulation congestion, which might lead to accumulation of the metabolic toxin.
