In uveitis, vitreous opacity causes decreased intraocular transparency, obscuring changes in the fundus. Moreover, severe inflammation can affect retinal function. Therefore, in cases with severe inflammation, prompt surgical intervention is very important, because visual impairment may become more severe if treatment is delayed. Here, we retrospectively analyzed electroretinogram (ERG) test results in uveitis that required surgical treatment and examined whether ERG was a useful indicator of surgical intervention.
Twenty-seven patient with uveitis were examined in this study. In a flash ERG examination, the amplitude and implicit time of the a- and b-waves were compared with the target eye. Groups that did and did not receive surgical treatment were compared with a statistical analysis.
In the surgical treatment group, the a- (p<0.01) and b-wave (p<0.01) amplitudes were attenuated. Moreover, the implicit time of the a-wave was significantly later than in the non-surgical treatment group (p<0.01).
The amplitude of the a- and b-waves in ERG testing was attenuated in uveitis patients that underwent surgical treatment. The implicit time of the a-wave was also significantly later in that group. This suggests that the ERG test is useful as an indicator of surgical intervention.
