Photopic 30 Hz flicker ERG as a predictor for rubeosis in central retinal vein occlusion

Table 1

The 95% confidence intervals and p values for the amplitudes and implicit times in the photopic and scotopic 30 Hz flicker ERG for the patients who developed rubeosis and for those that did not

Rubeotic Non-rubeotic p Value
Photopic implicit times (ms) 36.8–39.4 29.7–32.0 0.0000000004
Photopic amplitudes (μV) 12.6–33.0 21.4–33.1 0.29
Scotopic implicit times (ms) 39.5–41.6 33.5–35.8 0.000000015
Scotopic amplitudes (μV) 15.4–32.0 28.0–46.9 0.06
