We read with interest the article by Dierks et al¹ comparing the short-term effects of intravitreal injection of Kenalog-40 (Bristol-Myers Squibb, Princeton, NJ) with intravitreal injection of the vehicle and of triamcinolone acetonide in rabbit eyes. A 10% to 25% increase in a- and b-wave electroretinographic amplitudes of eyes with intravitreal injection of Kenalog-40 or triamcinolone compared with noninjected eyes was reported, although the probability of this being a chance finding (P value) was not stated.

Furthermore, the ratio of a- and b-wave amplitudes in the injected eyes to control eyes was compared across groups; there were no statistical differences except for an increase in the dark-adapted b-wave amplitude ratio only between the Kenalog-40 and vehicle groups at only 1 of 7 stimulating intensities (there was no statistical difference comparing intravitreal injection of the vehicle with intravitreal injection of triamcinolone). Details concerning the Bonferroni correction, which adjusts for multiple . . . [Full Text of this Article]
