We read with interest the article by Dierks et al1comparing 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.
