Anterior Chamber
The area inside the eye, behind the cornea, and in front of the iris
Aqueous Humor
A clear, watery fluid produced by the ciliary muscle. It fills the front part of the posterior chamber and
the entire anterior chamber. It provides nutrients for the lens and posterior cornea and carries away
waste products. It is also responsible for maintaining the intraocular pressure because it is the only
fluid continually produced in the eye.
Choroid
,Consists primarily of blood vessels that nourish the retina so that it can continue to function. it is
sandwiched between the sclera and the retina.
Ciliary Muscle
The muscle inside the eyeball that alters the shape of the crystalline lens. It has direct control over the
focusing ability of the eye. The focusing ability of the eye is called accommodation.
Conjunctiva
The clear, cellophane-like tissue that covers the sclera and the inside surface of the eyelids. The
palpebral conjunctiva lines the lids, while the bulbar conjunctiva covers the sclera.
Cornea
The clear transparent tissue that is located on the very front (anterior) portion of the eye. The cornea
is the most powerful refractive media of the eye. It provides most of the eye's ability to focus light. It
has a curvature somewhat greater than the rest of the globe, so a slight furrow marks its junction with
the sclera. The cornea has no blood vessels (avascular).
Crystalline Lens
Provides focusing power to the eye. It allows adjustment of the eye to focus from distance objects to
near objects. It is the second most powerful refractive medium.
Medial Rectus
The most powerful of the extraocular muscles. It's only action is to turn the eye toward the nose
(adduction).
Inferior Rectus
Its primary action is to turn the eye downward (depression). it also adducts the eye. Additionally, it
can rotate the eye toward the temple and the bottom of the eye toward the nose (extorsion).
Lateral Rectus
Its only action is to move the eye away from the nose (abduction).
Superior Rectus
Its primary action is to move the eye upward (elevation). It also adducts the eye. Additionally, it can
rotate the top of the eye toward the nose and the bottom of the eye toward the temple (intorsion).
Superior Oblique
Its primary action is intorsion. It is also responsible for depression and abduction.
Inferior Oblique
The only extraocular muscle that has its origin at the front of the orbit. Its primary action is extorsion.
It is also responsible for elevation and abduction.
Fovea Centralis
Area in the macula, approximately 1.5mm in diameter, where visual acuity is the sharpest. the fovea
contains the highest number of cones, which are responsible for daytime vision and color vision.
, Fundus
The bottom or base of and organ, or part of a hollow organ farthest from its mouth. In eye care,
fundus refers to the interior surface of the eyeball.
Iris
The colored part of the eye as you look into someone's eyes. The iris consists of two circular muscles
with a hole in the middle called the pupil. The iris sphincter and the dilator muscles control the size of
the pupil for maximum visual performance.
Lens
The resilient, transparent structure in the eye that focuses light by changes of curvature of its front
surface. It is located near the front of the eye, directly behind the pupil.
Macula
The central part of the retina, which is used for seeing detail. It is an area from 3 to 5mm in diameter,
with the foveal depression at its center.
Ocular Adnexa
The adjacent structures of the eye, such as eyelids, lashes, eyebrows, lacrimal apparatus, tarsal plates,
orbit, extraocular muscles and conjunctiva.
Optic Disk
The appearance of the optic nerve when viewed through the pupil. The portion of the optic nerve that
is formed by the meeting of all the retinal nerve fibers. It is insensitive to light and corresponds to the
physiological blind spot. the appearance of the optic disk can be used to determine the healthiness of
the nerve itself.
Optic Nerve
The nerve that carries impulses from the retina to the brain. It transmits the signals from the rods and
cones to the brain.
Orbit
The bony socket that contains the eye and most of its accessory organs. The roof, medial wall and
floor are very thin and can be easily damaged by injury, infection, or tumors.
Posterior Chamber
The area located inside of the eye, behind the iris, and in front of the lens.
Pupil
The round hole in the center of the iris through which light passes.It ordinarily appears black because
there is very little light coming from the dark chamber behind it.
Retina
