Macula - Wikipedia
WEBThe macula (/ˈmakjʊlə/) [1] or macula lutea is an oval-shaped pigmented area in the center of the retina of the human eye and in other animals. The macula in humans has a diameter of around 5.5 mm (0.22 in) and is subdivided into the umbo, foveola, foveal avascular zone, fovea, parafovea, and perifovea areas. [2]
The Function of the Normal Macula | BrightFocus Foundation
WEBJul 1, 2015 — The macula is located near the center of the retina; its function is to process harp, clear, straight-ahead vision. The retina is the paper-thin tissue that lines the back of the eye and contains the photoreceptor (light sensing) cells (rods and cones) that send visual signals to the brain.

WEBThis study measures and defines normal macular thickness values in healthy eyes using OCT3 mapping software. To our knowledge, this is the first study to provide normative macular thickness data for the OCT3 system.
Macula - American Academy of Ophthalmology
WEBA, The normal macula is identified histologically by a thick, multilayered GCL and a central area of focal thinning, the foveola. Note the NFL (arrowhead) in the nasal macular region and the oblique orientation of Henle fiber layer (perifoveal OPL) (asterisk). Clinically, the macula lies between the inferior and superior temporal vascular arcades.

WEBApr 7, 2022 — The retina is made of two parts, the macula and the peripheral retina. The macula is in the center of your retina and processes most of what you’re directly looking at. The peripheral retina fills in the parts of your vision at the edges of your visual field (your peripheral vision).

WEBOct 8, 2011 — Approximately 17 degrees (4.5-5 mm), or two and half disc diameters to the left of the disc, can be seen the slightly oval-shaped, blood vessel-free reddish spot, the fovea, which is at the center of the area known as the macula by ophthalmologists.
Anatomy and Histology of the Macula | SpringerLink
WEBOct 31, 2020 — The macula is recognized as a specially differentiated region of retina with high-resolution visual acuity with a unique structure of the neural, glial cells and vasculature. Pathogenesis of macular diseases depends on the underlying aetiology involving complicated and multifactorial mechanisms.
Why the macula? - PMC - National Center for Biotechnology …
WEBNov 17, 2017 — Macular photoreceptor cells have long axons, and the outer segments of foveal cones resemble physically those of rods rather than peripheral cones. In the macula, Müller cells are long and subserve the needs of photoreceptor cells except at the foveolar, where they are short and exist in a 1:1 ratio with cones.
