The Eye lies in the front half of the orbit surrounded by fat and connective tissue and is
supported by a facial hammock , It has an almost spherical shape with an average
diameter of 23 mm , The optic nerve, which connects the eye with the brain leaves the
orbit at its apex through the optic foramen in which it lies close to the ophthalmic artery.
The Eye ball surrounded by protective structures(orbit, lids, conjunctiva, and lacrimal
apparatus ) , the movement apparatus consisting of the extrinsic ocular muscles
and Tenon’s capsule , and supported by Ophthalmic artery .
Clinically, the eye can be considered to be composed of two segments:
1. Anterior segment – all structures from (and including) the lens forward .
2. Posterior segment – all structures behind the lens .
The FUNCTION of the eye is to form a clear image of objects in our environment.
These images are transmitted to the brain through the optic nerve and the posterior
visual pathways .

The anterior one-sixth of the fibrous layer of the eye is formed by the cornea. It is
avascular transparent convex portion & has an elliptical shape with the dimensions
10.6 mm vertically and 11.7 mm horizontally. It is approximately 1mm thick at the
limbus reducing to 0.52mm +/- 0.02mm centrally . At 43 diopters, the cornea is the
most important refractive medium in the eye.
It formed during the second month of embryonic development , & Histologically
the cornea consists of 3 layers and 2 membranes:
1- Epithelium (approx. 40-50 μm): consisting of five or six layers divided into;
Basal cell layer , Wing cells , & Superficial cells . It regenerates quickly when injured by
cell division .
2- Bowman’s membrane (approx. 8-14 μm): a thin structureless homogeneous layer ,
this layer is never replaced once destroyed .

21Pg. 3
3- Stroma ( approx. 450-500 μm) : consists of approximately 90% of
total corneal thickness. Consists of lamellae of collagen aligned at 90°
to each other and the spacing of the collagen fibrils is highly ordered.,
Between the lamellae are found cells (keratocytes) responsible for the
production of collagen and ground substance Corneal transparency is
due to the regular arrangement and relative dehydration of the collagen
fibres within the stroma..
4- Descemet’s membrane (approx. 5-10 μm) : a thin elastic membrane
resistant to both infection and trauma and relatively strong membrane
but lost tissue is not regenerated .
5- Endothelium (approx. 4 μm) : a single layer of hexagonal not
regenerated cells

31Pg. 2
The primary function of the cornea is refraction (approx. 43 diopters).
The cornea is the eye window that allows to form a clear image .
The cornea is a protective layer to the inner components of the eye .
The water content of the cornea controlled by epithelium(prevent the
passage of fluid into the stroma) and endothelium (pump the fluids into
the aqueous) to provide corneal dehydration to keep its transparency.
The uniform arrangement of the lamellae of collagen fibrils in the
corneal stroma also help to maintain the corneal transparency .
The epithelium and the endothelium attach with the tear that give the
nutrition to the cornea .

1Pg. 2
The Sclera
The whitish opaque outer coat of the eye which form 5/6 of the outer
layer of the eye
formed by the sclera .
All six ocular muscles insert into the sclera .
The sclera is thickest (1mm) anteriorly at the limbus & thinnest
(0.3mm) beneath the insertions of the rectus muscles .
It joins with the :
* Cornea at the limbus ,
* Optic nerve enter the sclera at lamina cribrosa ,
* The angle of the anterior chamber , to form the trabecular network
and the canal of Schlemm .
XThe Sclera
←Back

21Pg.
The Sclera
The sclera is fibrous , and consists of :
* layer of loose connective tissue deep to the conjunctiva, over laying
the sclera, called the episclera.
* A cellular connective tissue with a higher water content than the
cornea .
* Stroma consists of irregular lamellae of collagen fibers (this is the
cause of its whitish opaque appearance) .
The most important FUNCTION of the sclera is to protect the eye by
its rigid formation , & cut the light entering the eye off except from the
cornea .
XThe Sclera

The uveal tract is the middle highly vascular layer of the eye ,
consists of:
The uveal tract lies between the sclera and retina.
The real FUNCTION of this layer is to give the supply for some other
parts of the eye .
* The choroid* The Ciliary body* The Iris

1Pg. 2 3
It is a thin circular disc perforated centrally by the pupil.
The iris consists of two layers:
1- The anterior mesodermal stromal layer.
2- The posterior ectodermal pigmented epithelial layer ( an opaque and
protects the eye against excessive incident light).
Its variable pigmentation determines the 'colour' of eyes.
The color of the iris varies in the individual according to the melanin
content of the melanocytes (pigment cells) in the stroma and epithelial
layer.
Eyes with a high melanin content are dark brown, whereas eyes with less
melanin are grayish-blue .
←Back

21Pg. 3
The collarette marks the division of the stroma into pupillary and ciliary
zones.
The ciliary zone in the iris attached peripherally to the anterior surface of
the ciliary body .
The pupil is surrounded by :
1-The circular sphincter muscle, which is supplied by parasympathetic
nerve fibers ( responsible for miosis & contraction ) .
2- The radial dilator pupillae muscle, supplied by sympathetic nerve
fibers ( responsible for mydriasis & dilatation ) .
As similar as fingermarks , the iris has its unique map that never reoccur
with another one .

31Pg. 2
The iris regulate the contraction and dilation of the pupil by its muscles,
so that, it may be regarded as the light regulator of the optical system of
the eye.
It acts as an aperture to improve the quality of the resulting image by
controlling the amount of light that enters the eye.

Sympathetic innervation of pupil

Parasympathetic innervation of pupil

1Pg. 2
The ciliary body extends from the root of the iris to the ora serrata,
where it joins the choroid & the retina .
It is triangular in cross section , which has two sides :
1- The outer side ; is the ciliary muscles .
2- The inner side ; divided into two zones :
A- The pars plicata forms the anterior 2mm and is covered by ciliary
processes .
B- The pars plana constitutes the posterior 4.5-mm flattened portion of
the ciliary body (this zone which continuous with the choroid and retina).
←Back

21Pg.
The suspensory ligament, the zonule, extends from the pars plana and
the intervals between the ciliary processes to the lens capsule.
The ciliary body is covered by a bilaminar epithelium , which is
responsible for the production of aqueous humor.
The contraction of the ciliary muscle is responsible for
accommodation.
The epithelium layer covering the ciliary body produces the aqueous
humor.

The choroid is the middle tunic of the eyeball between the
sclera & the retina . It is highly vascularized, that, the blood flow
through the choroid is the highest in the entire body . In addition to
vessels, it also carries approximately 15–20 ciliary nerves.
The choroid consists of the following :
1- Bruch’s membrane 2 μm ; It consists of basement membrane of
retinal pigmented epithelium cells & elastic and collagenous layers .
2-The choriocapillaris whish supplying the RPE & outer retina .
3- Layer of larger choroidal blood vessels .
4- Pigmented cells .
The FUNCTION of choroid is to regulate temperature and supply
nourishment to the outer layers of the retina, it is the vein of life .

1Pg. 2
Is a transparent, bi-convex structure suspended from the ciliary body by the zonular fibres and
situated between the iris and the vitreous The lens is about 9mm in diameter and about 4mm thick
at the centre. The lens is comprised of 65% water and 35% protein .
Anatomically , the lens consists of :
1- A thick elastic capsule for protection (its elasticity decreases with aged) . The zonule inserts into it
near the equator to suspend the lens by ciliary body.
2- Layer of epithelial cells (just under the anterior capsule). It active metabolically to keep the lens
clean .
3- Lens fibres ; The central lens fibres are called the nucleus and the more peripheral fibres the
cortex .
4- Embryonic nucleus , forms by the growth of primary lens fibers then displaced toward the
center of the lens by the growth secondary one .
5- Fetal nucleus (complete at birth) , & Infantile nucleus ( complete during the 1st and 2nd decades of life)
←Back

21Pg.
The lens is one of the essential refractive media (10–20 diopters, depending
on individual accommodation) of the eye and focuses incident rays of light on
the retina .
Zonule filaments suspend the lens ciliary processes to the ciliary muscle .
When the muscle contracts the filaments relax allowing the lens to
become more convex with a shorter focal length for reading .

The gelatinous vitreous body consists of 98% water and 2%
collagen fibers and hyaluronic acid. It fills the vitreous chamber, which
composed approx. 2/3 of the total volume of the eye .
To provide mechanical stability , the 3-D network of collagen fibres &
hyaluronic acid molecules is attached to adjacent structures at the
following locations :
1- At the ligament of Wieger along the posterior capsule of the lens.
2- At the vitreous base at the ora serrata.
3- At the funnel of Martegiani (approximately 10 μm wide) surrounding the
periphery of the optic disk.
The FUNCTIONN of the vitreous body is to stabilizes the globe
although the eye can remain intact without the vitreous body .

41Pg. 2 3
The retina is the innermost of three successive layers of the globe. It
comprises two parts:
1- A photoreceptive part (pars optical retinae), comprising the first nine of
the 10 layers of retina .
2- A nonreceptive part (pars caeca retinae), forming the epithelium of the
ciliary body and iris .
Thickness of the retina different from part to another , thinnest at ora
serrata & thickest at optic nerve .
Moving inward along the path of incident light, the individual layers of
the retina are :
←Back

Pg. 421 3
1. Inner limiting membrane (glial cell fibers separating the retina from the vitreous body).
2. Layer of optic nerve fibers (axons of the third neuron).
3. Layer of ganglion cells (cell nuclei of the multipolar ganglion cells of the third neuron).
4. Inner plexiform layer (synapses between the axons of the second neuron and dendrites of
the third neuron).
5. Inner nuclear layer (cell nuclei of the bipolar nerve cells of the second neuron, horizontal
cells, and amacrine cells).
6. Outer plexiform layer (synapses between the axons of the first neuron and dendrites of the
second neuron).
7. Outer nuclear layer (cell nuclei of the rods and cones = first neuron).
8. Outer limiting membrane .
9. Layer of rods and cones (the actual photoreceptors).
10. Retinal pigment epithelium (a single cubic layer of heavily pigmented epithelial cells).
11. Bruch’s membrane (basal membrane of the choroid separating the retina from the choroid).

431Pg. 2
The most sensitive section in the retina is THE
MACULAR :
The macula lutea (yellow spot); is a flattened oval area in the
center of the retina approximately 3–4mm(15 degrees)
temporal to and slightly below the optic disk with (1.7–2 mm)
diameter.
In its center; (the avascular fovea) , the sharpest visual
perception , which contains only cones cell .

41Pg. 2
The retina is the sensitive film of the eye , which receive the visible light
spectrum (wavelengths of 380–760 nm) to send it to the brain as Electric
signals .It has 4 types of Perceptions : Contrast, color, light and shape.
The retina has two types of photoreceptors :
1- The Rods (110–125 million rods) responsible for twilight and night vision,
they are about 500 times more photosensitive than the cones .
2- The Cones (six to seven million cones) responsible for say light vision ,
resolution, and color perception & there are three types of cones:
1- Blue cones, 2-Green cones, 3- Red cones.
* There are nearly 20 rods to every cone.

The optic nerve extends from the posterior pole of the eye to the optic
chiasm with total length of (35–55mm) . The nerve consists of :
1- An intraocular portion (Optic Disk) .
2- An intraorbital portion.
3- An intracranial portion.
The optic disk normally has oval shape with area (approx. 2.7mm²) &
diameter (approx. 1.8mm) with yellowish orange color .
The optic cup is eccentric cavitation of the optic nerve with oval shape.
It is the brightest part of the optic disk.
The FUNCTION of the optic nerve is to send the electric signals of
light to the brain & suspend the globe in its place in the orbit .

The eye adnexa is that parts whish surrounded the eye globe .
It consists of :
The adjacent eye adnexa very important for the safety of the
eye & its movement .
* The Eye Lids * The Lacrimal
System
* The Conjunctiva * Extra-Ocular
Muscles

The anatomy of an eyelid can be simplified into four layers :
1- Skin, which is formed by the epidermis and dermis .
2- Striated muscle, formed by the orbicularis oculi to close the eyelids.
3- Tarsal plate which gives the eyelid firmness and shape and
containing the Meibomian glands .
4- Conjunctival mucosa .
On the upper eyelid, approximately 150 eyelashes are arranged in three
or four rows; on the lower eyelid there are about 75 in two rows. As
eyebrows,the eyelashes help prevent dust and sweat from entering the eye.
Different types of muscle groups specialize in eyelid movements, whose
closing takes three forms:
- By blinking, - By reflex, - And consciously.
The superficial
layer
The deep
layer

21Pg.
Normal width of the palpebral fissure ( the eye opening ) :
- The upper lid covers the superior margin of the cornea by about
(2mm).
- The lower lid close to the inferior margin of the cornea .
- The distance between upper & lower lids is normally (6–10mm) .
- The distance between the lateral and medial angles is (28–30mm) .
The FUNCTION of the eye lids is :
1- protect the eye globe .
2- It contains tear film, which is significant for corneal moisture & healthy
that distributed over the anterior surface by blinking .

1Pg. 2
The conjunctiva is a vascular mucous membrane that covers
the surface of the globe and the lids.
Anatomically, the conjunctiva has continuous regions consist
of :
1-The palpebral conjunctiva : lines the posterior surface of the eyelids.
2-The forniceal conjunctiva : the link between palpebral & bulbar conj.
3-The bulbar conjunctiva : is loosely attached to the anterior of sclera .
4-The limbal conjunctiva : attached strongly to about 3mm from the
cornea .
←Back

21Pg.
Histologically, the conjunctiva consist of :
1- The epithelium layer : contains basal, wing, and superficial cuboidal
layers . & contains goblet cells (mucous glands), langerhans cells, and
melanocytes cells .
2- The stroma : contains nerves, blood vessels, and lymphatic .
The FUNCTION of the conjunctiva is to facilitate the movements of
the globe and lids while protecting the orbital contents from the external
environment.

1Pg. 2
The lacrimal system consists of two sections :
* Structures that secrete tear fluid ( lacrimal gland, Krause and Wolfring glands ).
* Structures that facilitate tear drainage (drainage system ).
The lacrimal gland lies above the outer corner of the eye beneath the
superior temporal margin of the orbital bone in the lacrimal fossa. The
accessory Krause and Wolfring glands located in the conjunctival fornices.
Anatomically, the lacrimal drainage system consists of :
1- The punta (2mm) : lie in papillae at the medial ends of the eyelids.
2- Canaliculi (8mm) : 70% of tears drain through the inferior and 30% through the
superior canaliculus .
3- The lacrimal sac : lies in the lacrimal groove formed by the lacrimal bone and the
frontal process of the maxilla.
4- Nasolacrimal duct (NLD) : is directed downwards, laterally and
backwards to empty into the inferior meatus of the nasal cavity.

21Pg.
The Tear Film :
Is a protein layer consists of three layers :
1- The outer oily layer (approx. 0.1 μm) : produced meibomian glands
and the sebaceous glands and sweat glands of the margin of eye lids . This
layer very important to stabilize the tear film and prevent evapration.
2- The middle watery layer (approx. 8 μm ) : is produced by the lacrimal
gland and the accessory lacrimal glands . It is important for sterilization,
cleaning the surface of the cornea & facilitation of blinking .
3- The inner mucin layer (approx. 0.8 μm) : is secreted by the goblet cells
of the conjunctiva and the lacrimal gland. It helps to stabilize the tear film
and protect the corneal epithelium .

The external ocular muscles (4 rectus, and 2 oblique) lie in the
fat of the orbit and help to move the eyeball in different
directions.
All the recti muscles attach to the eyeball anterior to the
equator (inserted into the sclera 5-8mm from the limbus) while
the oblique muscles attach behind the equator.
