Percent difference in ERG amplitudes between ribozyme-treated and control eyes after injection at P15

Ribozyme	Age analyzed	n	b wave	P	a wave	P
Hh13	P180	3	38.1%	<0.0005	27.7%	<0.005
Hh13	P240	2	45.3%	NS	—	—
Hp11	P240	2	28.5%	NS	7.4%	NS

All values of ribozyme-treated eyes are greater than those of control eyes. NS, not significant.
