There are typically four vortex veins (one in each quadrant), but there could be up to ten. In each of the eye’s four quadrants, the choroidal veins empty into a vortex vein. Finding the vortex veins is clinically one of the simplest ways to detect the fundus’ equator. The fundus’s equator is located 14 to 15 mm or so away from the limbus. It is located between the superior and inferior temporal arteries. The retina’s area centralis is a circular region with a diameter of 5–6 mm. 2 The retina has an average thickness of 200 micrometres it is slightly thicker between the macula and the optic nerve head and gradually becomes thinner at the ora serrata and the fovea. Layers of Retina- The human retina has a surface area of around 1,100 square millimetres and measures 32 millimetres from ora to ora along the horizontal meridian. Layers of Retina Anatomy Anterior to Posterior Know All About Human Eye Layers of Retina Diagram Layers of Retina Layers of Retina Physiology The black pigment melanin in the pigment layer reduces light reflection around the globe of the eyeball, which is crucial for good vision. The neural retina is nourished and supported by this layer, which is closest to the choroid. One layer of cuboidal epithelial cells makes up the retinal pigment epithelium.Rods and cones are divided between inner and outer segments, with the outer segments containing a highly sophisticated light-sensing device.The layer that divides the photoreceptors’ inner segment components from their cell nuclei is known as the external limiting membrane.Rods and cones’ cell bodies make up the outer nuclear layer.This is referred to as the Fiber layer of Henle in the macular area. Outer plexiform layer – rod and cone projections that join the dendrites of horizontal and bipolar cells at the rod spherule and cone pedicle, respectively.Amacrine cells, bipolar cells, and horizontal cells’ nuclei and surrounding cell bodies are found in the inner nuclear layer.The synapse between the axons of the bipolar cell and the dendrites of the ganglion and amacrine cells is located in the inner plexiform layer.The ganglion cell layer is composed of the nuclei of ganglion cells, whose axons develop into the fibres of the optic nerve, as well as a few dislocated amacrine cells.A thin layer of Müller cell footplates is present between the nerve fibre layer and the inner limiting membrane, which can be seen as the axons of the ganglion cell bodies.Müller cells create the inner limiting membrane and basement membrane.From the vitreous body outward, in order of proximity: The retina of a vertebrate comprises ten different layers. Layers of the Retina have been discussed here. Layers of Retina details are given below. The retina performs a function that is similar to the film or image sensor of a camera in many respects. The retina receives a focused two-dimensional image of the visual world from the eye’s optics, analyses it there, and sends nerve impulses carrying that processed image to the visual cortex via the optic nerve to produce vision. For most vertebrates and some molluscs, the retina is the innermost, light-sensitive layer of tissue in the eye. To know about Layers of Retina first, we know about Retina.
