Histopathological and GFAP immune reactivity features in BSS and imatinib-injected eyes. Note the remarkable retinal layers in BSS-injected (a) and 40 µg imatinib-injected (b) eyes (hematoxylin and eosin, magnification ×200). There is severe retinal atrophy and disorganization together with pigment migration into the retina in 165 µg (c) and 330 µg (d) imatinib-injected eyes (hematoxylin and eosin, magnification ×200). GFAP immunoreactivity, as compared to a BSS-injected eye (e) was not significant in the 40 µg-injected (f) eye (magnification ×400). GFAP glial fibrillary acidic protein, BSS balanced salt solution
