What is the fovea vs macula?
The macula is the pigmented part of the retina located in the very center of the retina. In the center of the macula is the fovea, perhaps the most important part of the eye. The fovea is the area of best visual acuity. It contains a large amount of cones—nerve cells that are photoreceptors with high acuity.
Where is the macula or fovea located?
retina
The fovea centralis is located in the center of the macula lutea, a small, flat spot located exactly in the center of the posterior portion of the retina. As the fovea is responsible for high-acuity vision it is densely saturated with cone photoreceptors.
What is a fovea in the eye?
The fovea centralis, or fovea, is a small depression within the neurosensory retina where visual acuity is the highest. The fovea itself is the central portion of the macula, which is responsible for central vision.[1][2][3][4]
What does the macula of the eye look like?
The macula is an oval-shaped pigmented area near (5°=1.5 mm away from) the center of the retina of the human eye and other animal eyes.
What does fovea look like?
The human fovea is densely packed with cones. It looks like a little pit on the retina because the cells that are above the retinal surface, such as retinal ganglion cells, horizontal cells, and amacrine cells, are swept away so that the cones are at the surface.
What is the eye macula?
The macula is part of the retina at the back of the eye. It is only about 5mm across but is responsible for our central vision, most of our colour vision and the fine detail of what we see. The macula has a very high concentration of photoreceptor cells – the cells that detect light.
What fovea contains?
Fovea is Latin for small pit, and it was identified as a characteristic of human retina by the late eighteenth century. 2. The foveal center or ‘foveola’ contains the highest density of cone photoreceptors in the retina. Cone photoreceptors function in bright light and support high acuity and color vision.
Is fovea the blind spot?
The blind spot (Fovea centralis) The blind spot is located about 15 degrees on the nasal side of the fovea.
What is macula thickness?
The mean macular thickness for all subjects was 262.8±13.34 µm. Macular thickness for all subjects in each of the 9 regions of the ETDRS map is presented in Table 1. Macular thickness was thinnest at the fovea (innermost 1 mm ring), thickest within the inner 3 mm ring and diminished peripherally.
What is eye macula?
What is macula of eye?
How do you find the macula?
To look at the macula, ask the patient to look directly into the ophthalmoscope light. The ophthalmoscope can also be used for examining the anterior part of the eye by turning the lens dial to ∼ +10.
