Duplex retina

Duplex retina is a type of retina found in the eyes of many vertebrates, including humans. It is characterized by the presence of both rod cells and cone cells, which allow for both high sensitivity to light and color vision.

Structure

The duplex retina consists of two types of photoreceptor cells: rod cells and cone cells. Rod cells are more numerous and are responsible for vision in low light conditions, while cone cells are less numerous and are responsible for color vision and visual acuity.

Function

The duplex retina allows for a wide range of visual capabilities. The rod cells provide high sensitivity to light, allowing for vision in low light conditions. The cone cells, on the other hand, provide color vision and high visual acuity, allowing for detailed vision in bright light conditions.

Clinical significance

Abnormalities in the duplex retina can lead to a variety of vision disorders. For example, a lack of rod cells can lead to night blindness, while a lack of cone cells can lead to color blindness.
