The density of choline acetyl-transferase-IR (ChAT-IR), [gamma]-aminobutyric acid-IR, and Disabled-1-IR (Dabl glycinergic AII) amacrine cells in control central INL was 1.9 [+ or -] 0.2, 7.3 [+ or -] 0.5, and 4.8 [+ or -] 0.3 per 100 [micro]m length, respectively.
They injected a substance into the retina to eliminate ganglion cells, a type of nerve cell found near the surface of the retina, and amacrine cells. Then by injecting the eye with epidermal growth factor (EGF), fibroblast growth factor 1 (FGF1) or a combination of FGF1 and insulin, they were able to stimulate the Muller glia cells to re-start their dividing engines and begin to proliferate across the retina.
Glucagon-containing amacrine cells of the chick retina have been found to respond differentially to the direction (plus or minus) of defocus within two hours of either positive or negative lens wear.
Structural remodeling was observed in amacrine cells of patients with retinitis pigmentosa [9] and to some extent after retinal detachment-reattachment in a feline model [5].
Inhibitory interneurons of the mammalian retina include amacrine cells and several types of horizontal cells [91].
The most consistent and widely reported aspect of the ERG that changes early in DR using animal models and patients is the oscillatory potential implicit time which reflects electrophysiological communication between the amacrine cells and the bipolar cells with interactions from ganglion cells to amacrine cells.[sup][20] Such early indicators reflect retinal neural dysfunction and perhaps progression to neurodegenerative pathology in the later stages of disease.
However, those investigators reported that visual functional disorders were unclear in patients with OP abnormalities who have no or minimal fundus changes and presumed that amacrine cells were the most feasible candidates for OP generation [27].
