Anatomia del Oculo

Vitreous Humor

• Gel-like substance filling the interior of the eye, providing shape and structure.
• Maintains intraocular pressure and supports the retina.

Optic Disc

• Also known as the blind spot, where the optic nerve exits the eye.
• Lacks photoreceptors, resulting in a point that cannot detect light.

Optic Nerve

• Transmits visual information from the retina to the brain.
• Comprised of thousands of ganglion cell axons, crucial for vision.

Retina

• Layer of tissue at the back of the eye that captures light and converts it to neural signals.
• Contains photoreceptors (rods and cones) that enable vision in different lighting conditions.

Choroid

• Vascular layer between the retina and the sclera, supplying nutrients and oxygen.
• Contains pigment that absorbs excess light to reduce glare.

Sclera

• White outer layer of the eye, providing protection and structure.
• Provides attachment points for eye muscles, assisting in eye movement.

Posterior Chamber

• Space behind the iris and in front of the lens, filled with aqueous humor.
• Helps maintain intraocular pressure and nourishes the eye structures.

Anterior Chamber

• Fluid-filled space between the cornea and the iris.
• Contains aqueous humor that is continuously produced and drained to maintain pressure.

Anterior Cavity

• Inclusive term for both the anterior and posterior chambers.
• Houses aqueous humor, crucial for maintaining eye shape and pressure.

Cornea

• Transparent front layer of the eye, crucial for focusing light.
• Avascular but richly supplied with nerve endings, contributing to sensitivity.

Pupil

• Adjustable opening in the center of the iris, controlling the amount of light entering the eye.
• Can dilate or constrict in response to light intensity.

Iris

• Colored part of the eye, consisting of muscle fibers that regulate pupil size.
• Determines eye color and contributes to the adjustment of light entering the eye.

Lens

• Transparent structure behind the iris that aids in focusing light on the retina.
• Changes shape to allow for accommodation (focusing on near or distant objects).

Ciliary Body

• Muscle and tissue structure that supports the lens and helps adjust its shape.
• Produces aqueous humor and connects the iris to the lens.

Suspensory Ligament

• Fibers attaching the lens to the ciliary body, aiding in lens shape adjustment.
• Plays a role in maintaining the lens position and facilitating accommodation.
