The neural layer of the retina is mainly composed of these three types of neurons.
- photoreceptors (rods and cones)
- bipolar cells
- ganglion cells
The weak spot of the fundus (posterior wall) that lacks photoreceptors. Also called the "blind spot".
Photoreceptors that are more numerous. Are dim-light and peripheral vision receptors.
Photoreceptors which operate in bright light and high color.
Neurons of retina that respond to light.
Neurons of retina that are the locations for generation of action potential.
Path of light entering the eye.
- aqueous humor,
- vitreous humor,
- then through entire thickness of neural layer.
Vision problem in which distant objects are focused in front of the retina, making them blurry. Typically results from an eyeball being too long. Corrected with concave lenses.
Vision problem in which light rays are focused behind the retina. Close objects appear blurry. A result of an eyeball being too short. Corrected with convex lenses.
Unimpaired, normal vision.
