Macula anatomy. In the center of the macula is the fovea perhaps the most important part of the eye. The macula is a circular area of diameter 55 mm with a center located 17 degrees or 40 50 mm temporal and 053 08mm inferior to the center of the optic disc. The normal central retinal artery black arrow is located nasal to the central retinal vein green arrow in the optic disc.

The bundle of nerve fibers at the back of the eye that carry visual messages from the retina to the brain. When the gaze is fixed on any object the centre of the macula the centre of the lens and the object are in a straight line. The macula is a small but important area in the center of the retina.

A number of eye problems can affect the macula and can lead to vision loss if they are not treated. An area of the eye near the center of the retina where visual perception is most acute. Macula lutea macula lutea is a 55 mm circular area deeper red than rest.

Anatomy of macula 1. It is one hundred times more sensitive to detail than the peripheral retina. The fovea is the area of best visual acuity.

Vestibule of sensory cells called a macula which is about 2 mm 008 inch in diameter. Vestibular structures of sensory cells called a macula. Contents anatomy of macula lutea embryology blood supply macular function tests.

The light sensing nerve cells rods and cones located in the retina. It is marked by the presence of multiple cyst like cystoid formations which cause edema swelling in the macular area resulting in blurred or decreased central vision. Cystoid macular edema cme is a painless disorder affecting the macula.

It contains a large amount of conesnerve cells that are photoreceptors with high acuity. The portion of the eye at the center of the retina that processes sharp clear straight ahead vision. The macula is responsible for the sharp straight ahead vision that is used for seeing fine detail reading driving and recognizing faces.

Macula lutea in anatomy the small yellowish area of the retina near the optic disk that provides central vision. The macula or macula lutea is an oval shaped pigmented area near the center of the retina of the human eye and some other animalian eyes. Mechanical senses of hair cells known as maculae.

You need the macula to clearly see details of objects in front of you like faces and written text. The macula is the pigmented part of the retina located in the very center of the retina.
