What layers of the retina are in the fovea?

The foveal pit now contains a very thin, only one layer thick, ganglion cell layer, a thin inner plexiform layer (IPL) but a prominent inner nuclear layer (INL) (Figure 10, a). The cones are now evident as straight vertical cones with synaptic pedicles, cell bodies and inner segments.

What is the foveal reflex?

The foveal reflex is a bright pinpoint of light that is observed to move sideways or up and down in response to movement of the opthalmoscope. [ from HPO]

What are the 3 main layers of the retina?

The retina is organized into three primary layers, the photoreceptive layer, the bipolar cell layer, and the ganglion cell layer.

What is the difference between fovea and Foveola?

In context|anatomy|lang=en terms the difference between fovea and foveola. is that fovea is (anatomy) the retinal fovea, or fovea centralis, responsible for sharp central vision while foveola is (anatomy) the center of the fovea in the macula of the eye, approximately 035 mm in diameter, containing only cone cells.

Where is the foveal reflex?

The reflex is actually located in the vitreous body as a result of the shape of the fovea. The fovea acts like a concave mirror which gathers the light from the ophthalmoscope and focuses it slightly in front of the retina as a point of light.

How do you check your foveal reflex?

Look for the presence of haemorrhage. The foveal reflex is a reflection of bright light of the ophthalmoscope from the foveal pit, appearing as a bright point of light that moves with the movement of the ophthalmoscope. It tends to be brighter in children.

What are the 10 layer of retina?

Layers from outside in: (1) retinal pigment epithelium; (2) rods and cones (photoreceptors); (3) external limiting membrane; (4) outer nuclear layer; (5) outer plexiform layer; (6) inner nuclear layer; (7) inner plexiform layer; (8) ganglion cell layer; (9) nerve fiber layer; (10) inner limiting membrane; (11) vitreous.

What are the ten layers of retina?

The retina can be divided into 10 layers including (1) the inner limiting membrane (ILM); (2) the nerve fiber layer (NFL); (3) the ganglion cell layer (GCL); (4) the inner plexiform layer (IPL); (5) the inner nuclear layer (INL); (6) the outer plexiform layer (OPL); (7) the outer nuclear layer (ONL); (8) the outer …
