WebMacular ganglion cell asymmetry was expressed as the absolute differences and the ratios between the inferior and superior hemispheres, inferotemporal (IT) and superotemporal (ST) areas, IT and superonasal (SN) areas, IT and inferonasal (IN) areas, and ST and IN areas. The asymmetry index was the absolute log10 of the ratio. WebApr 11, 2024 · The lamina cribrosa (LC) is a mesh-like connective tissue that allows the transition of the retinal ganglion cell (RGC) axons and the retinal blood vessels. Its main function is to surround and protect these ocular tissues and provide nutritional support. Lamina cribrosa also acts as a barrier between intravitreal and retrobulber compartments.
