PARS IRIDICA RETINAE Meaning and
Definition
-
Pars iridica retinae, also known as the iris portion of the retina, is an anatomical term used in the field of ophthalmology to describe a specific region of the retina adjacent to the iris.
The retina is the light-sensitive tissue lining the inner surface at the back of the eye, essential for vision. It contains specialized cells called photoreceptors that convert light into electrical signals, which are then transmitted to the brain for visual processing. The region of the retina known as the pars iridica is located closer to the front of the eye, specifically where the optic nerve exits the eye to send visual information to the brain.
The term "pars iridica retinae" derives from Latin, where "pars" translates to "part," "iridica" refers to the iris, and "retinae" refers to the retina. Therefore, it can be understood as the part of the retina associated with the iris.
This region of the retina contains various types of nerve cells, including ganglion cells, which receive signals from the photoreceptor cells and pass them along to the optic nerve. The pars iridica retinae is crucial for fine-tuning visual information related to the dilation and constriction of the pupil, which is controlled by the iris muscles. It plays a vital role in regulating the amount of light entering the eye and maintaining optimal visual clarity.
