Results of intraocular pressure and electroretinography from eyes with the different types of porous silicon particles (or 5% dextrose control)

Particle type	No. of eyes tested	Intraocular pressure (mm Hg)*	Electroretinography a-wave implicit (mS)	Electroretinography a-wave amplitude (μV)	Electroretinography b-wave implicit (mS)	Electroretinography b-wave amplitude (μV)†
Unmodified (fresh)	3 (OD)	18.7 (4) (at week 4)	16 (0)	20.3 (0.6)	71.3 (4.2)	70 (12)
5% dextrose	3 (OS)	15.7 (2) (at week 4)	16 (0)	20 (0)	71.3 (4.2)	85 (27)
Hydrosilylated	5 (OD)	18.2 (2) (at week 17)	12.3 (1.1)	31.3 (5.1)	67.3 (6.8)	143 (31.6)

Oxidised at high temperature	3 (OD)	15.3 (2) (at 12 months)	21.3 (2.3)	18.5 (1.5)	71.7 (10.4)	83.7 (27)
5% dextrose	3 (OS)	15.7 (2) (at 12 months)	21.3 (2.3)	18.8 (1)	65 (10)	91.3 (32.5)

^*Intraocular pressure was statistically analysed by paired t test (OD vs OS), p = 0.71.

^†b-Wave amplitude was statistically compared between OD and OS using a paired t test (p = 0.77).

OD, right eye; OS, left eye.
