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.
The macula in humans has a diameter of around 55 mm 022 in and is subdivided into the umbo foveola foveal avascular zone fovea parafovea and perifovea areas. It is one hundred times more sensitive to detail than the peripheral retina. The macula is responsible for the sharp straight ahead vision that is used for seeing fine detail reading driving and recognizing faces.
Anatomy of internal ear in senses. Cystoid macular edema cme is a painless disorder affecting the macula. The macula is a small but important area in the center of the retina.
The macula is the pigmented part of the retina located in the very center of the retina. A number of eye problems can affect the macula and can lead to vision loss if they are not treated. In the center of the macula is the fovea perhaps the most important part of the eye.
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 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 fovea is the area of best visual acuity.
The portion of the eye at the center of the retina that processes sharp clear straight ahead vision. An area of the eye near the center of the retina where visual perception is most acute. You need the macula to clearly see details of objects in front of you like faces and written text.
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. Macula lutea macula lutea is a 55 mm circular area deeper red than rest. The normal central retinal artery black arrow is located nasal to the central retinal vein green arrow in the optic disc.
Photopic color vision are primary functions of this area. Macula lutea in anatomy the small yellowish area of the retina near the optic disk that provides central vision.
