本文通过对８８例９３眼钝挫伤视网膜电图变化进行分析，得出结论：视网膜损伤越重，Ｆ－ＥＲＧ异常率越高，Ａｍｓ、Ｂｍｓ延长百分数越大，Ａｕｖ、Ｂｕｖ下降百分数越显著；治疗前、后视力越差，Ａｍｓ、Ｂｍｓ延长百分数越大，ＡｕｖＢｕｖ下降百分数越显著；并且通过治疗前，后视力与Ａｍｓ、Ａｕｖ、Ｂｍｓ、Ｂｕｖ进行多因素逐步回归分析，发现Ｂｍｓ与治疗前，后视力关系最为密切，因而认为Ｆ－ＦＲＧ是判断视网膜损伤程度的一项客观指标，为视力预后判断提供依据。
In this paper, 88 cases of 93 eyes with blunt traumatic retinal electrogram changes were analyzed, concluded that: the more severe retinal injury, the higher the abnormal rate of F-ERG, Ams, Bms elongation percentage, Auv, Buv decreased the more significant percentage; treatment The worse the anterior and posterior visual acuity, the greater the percent elongation of Ams and Bms, the more significant the decrease of the AuvBuv percentage. The multi-factor regression analysis of Ams, Auv, Bms and Buv before and after treatment showed that Bms was significantly correlated with before and after treatment Visual acuity most closely, so that the F-FRG is to determine the extent of retinal damage, an objective indicator for judging the prognosis of vision to provide the basis.
