Impact of single and combined neuroprotectants on TUNEL-positive cells in the ONL of superior retina one week after light exposure.

<p>We tested whether the number of TUNEL+ cells were significantly different among 5 experimental groups. In all three treated groups, the number of TUNEL+ profiles was significantly smaller than in the light damage (LD) group. The histogram bars show mean numbers of TUNEL+ cells/mm ONL, for each experimental group; the error bars show standard error of the means. Statistical significance indicator: ⁽***⁾ p<0.001.
