Figure 5.

(A and B) Representative histological sections from retinas subjected to 45 minutes of ischaemia and 7 days reperfusion. The structural injury, particularly to the inner retina, is considerably worse in the presence of hypoglycaemia (A), compared to normoglycaemia (B). Hypoglycaemia, without concomitant ischaemia, did not affect retinal structure (C) compared to an untreated control retina (D). GCL = ganglion cell layer; IPL = inner plexiform layer; INL = inner nuclear layer; ONL = outer nuclear layer. Solid bars indicate the thickness of the IPL.
