Table 2. Relations between changes in bleb parameters and the reduction rate of the IOP following LSL calculated by multiple regression analysis.

Bleb parameter	T-value	P-value
ΔTotal bleb height (mm)	−1.59	0.131
ΔFluid cavity height (mm)	2.2	0.0428*
ΔWall thickness (mm)	2.52	0.0226*
ΔWall intensity (optical density)	2.21	0.0420*
ΔWidth of filtration opening (mm)	2.29	0.0356*
ΔTFD average (mm)	−1.5	0.1533

Abbreviations: IOP, intraocular pressure; LSL, laser suture lysis; TFD, top filtration distance.
