[Topography and functional changes of the rabbit retina with a single injection of triamcinolone].
Intravitreal injections of 6 and 8 mg of triamcinolone (kenalog) were studied for impact on the time course of electroretinographic changes and the retinal structure of healthy rabbits. Histopathological study failed to reveal the signs of toxic damage to the retina. The electroretinographic findings suggest that kenalog primarily affect the function of photoreceptors and Muller's glia. The fact that the alteration of retinal functional activity may be linked with the early cytotoxic effects of the agent cannot be ruled out. However, the changes found in retinal electrogenesis are most likely to reflect the mechanisms of kenalog's beneficial therapeutic action that is primarily mediated through its effect on the function of photoreceptors and Muller's cells.
