Fig. 1. Scatter plot of IOP increase after WDT + DRPT compared with mean anterior chamber angle of the narrower eye.

Fig. 1

The vertical red line is set at 20° anterior chamber angle, considering <20° as angle closure and ≥20° as open. The horizontal red line indicates the cut-off value of 8 mmHg. An IOP increase of ≥8 mmHg demonstrates a positive WDT + DRPT.
