What is the role of the ora serrata?

The ora serrata is the serrated junction between the choroid and the ciliary body. This junction marks the transition from the simple, non-photosensitive area of the ciliary body to the complex, multi-layered, photosensitive region of the retina.

Is the ora serrata transparent?

The vitreous base is a semi-transparent substructure of the vitreous body located along the ora serrata (white arrows), which is the dividing line separating the ciliary body and retina. The anterior border of the vitreous base extends over the pars plana (white line) of the ciliary body.

What muscle is inserted in the ora serrata?

rectus muscle
Position of all rectus muscle insertions with reference to the ora serrata (20 eyes).

What are the 10 layers of the 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.

Why does the retina end at the ora serrata?

The ora serrata is the serrated junction between the retina and the ciliary body. This junction marks the transition from the simple non-photosensitive area of the retina to the complex, multi-layered photosensitive region.

What is uveal tissue?

The uveal tract has 3 main parts: (1) the choroid (the tissue layer filled with blood vessels); (2) the ciliary body (the ring of tissue that contains muscles that change the shape of the lens and makes the clear fluid that fills the space between the cornea and the iris; and (3) the iris (the colored part of the eye).

What does ora serrata separate?

Is the ora serrata part of the retina?

The ora serrata is the peripheral termination of the retina and lies approximately 5 mm anterior to the equator of the eye. Its name derives from the scalloped pattern of bays and dentate processes (see Chapter 3); the retina extends further anteriorly on the medial side of the eye.

What do bipolar cells do in the retina?

Bipolar cells are interneurons in the retina ( Vision), which transfer visual information from photoreceptors (rods and cones; Photoreceptors) to amacrine ( Retinal direction selectivity: Role of starburst amacrine cells) and ganglion cells ( Retinal ganglion cells).

What part of the eye carries visual information from the retina to the brain?

Optic nerve
Optic nerve: This cranial nerve sends visual information from your retina to your brain. It consists of more than 1 million nerve fibers. It’s a busy highway! Optic chiasm: Think of this like an intersection.

What does the ora serrata represent and why does it have this name?

At what age is the eyeball fully formed?

Your eyes and vision are fully developed when you reach your early 20s. They usually stay the same through your 30s. In middle age, your eyes go through changes.
