ANATOMY OF THE EYE
By
dr. Yuliana, M.Biomed
SUMMARY
The eyes lie within two bony orbits, located on either side of the root of the nose. The medial walls of the orbits are almost parallel. They border the nasal cavity anteriorly and the ethmoidal air cell and the sphenoid sinus posteriorly. The lateral walls border the middle cranial, temporal, and pterygopalatine fossae. Superior to the orbit is the anterior cranial fossa and the frontal and supraorbital sinus. The maxillary sinus and the palatine air cell are located inferiorly. Seven bones make up the bony orbit such as frontal, zygomatic, maxillary, ethmoidal, sphenoid, lacrimal, and palatine. The four rectus muscles insert anteriorly on the globe along the Spiral of Tillaux. Two oblique muscles are superior and inferior oblique muscle.Six of the twelve cranial nerves (CV II-VII) directly innervates the eye and periocular tissue.

HISTOLOGY OF THE EYE
DR. RATNAYANTI
Abstract
Like any other senses, eye is our window to the external world. Eye captures image continuously and transmits it to the brain for next processing and understanding. The structure of the eye is perfectly designed to perform its course. The light reflected by object enters the eye through cornea and pupil. The amount of light permitted is regulated by iris by dilating or constricting the pupil. Then, the refractive structures, lens and vitreous body, directing the light to the retina where it translated to a signal the brain can understand and perceived as an image. The shape and structure of the other eye walls support the photoreceptor function of the eye. The rigid and opaque sclera protects the eye and maintains the spherical shape needed for precise image in the back of the eye. The uvea provides nutrition and its melanin blocks lights from other angles, thus, only light comes from cornea is received. The accessory structures of the eye also support and protect the eye. It is consist of lacrimal gland, which produce tears; conjunctiva, covered the anterior part of the eye; and eye lids, the “on and off button” of the eye.

PHYSIOLOGY OF THE EYE
By Prof.dr.I Dewa Putu Sutjana, PFK,M.Erg
INTRODUCTION
The human know the environment because they had special senses, such as visual system, auditory, smell, taste, tactile which are call five senses. The visual system was control around 90% of the daily activity. The visual system detects and interprets light stimulations. The light stimulations are in form of electromagnetic waves of lengths between 400 to 700 nm, which make up visible light. The human can be known the environment because they had:
The optic system, for reflected the light enters the eye and focuses it on the retina The retina as photoreceptors transducer light energy into an nerves impulses
The optical neural, Neural pathways from the retina to the visual cortex at occipital lob of brain.
The visual cortex of the brain process nerve impulses into visual images.
I.OPTIC SYSTEM OF THE EYE
FORMATION OF AN IMAGE ON THE RETINA
The light from the objects refracted and focused by the optics system of the eye on the retina. The image is inverted and reversed with respect to the object. However, the mind perceives objects in the upright position.
PUPILLARY DIAMETER
Like in the camera the eye had the pupil which is formed by the iris. The major function of the iris is to control the diameter of the pupil. The diameter of the pupil is control the amount of light enters the eye. The stimulation of the parasympathetic nerve increases the diameter of pupil. The change of pupil diameter followed the accommodation
ACCOMODATION
The eye can be adjusted automatically the vision changes from the near to par objects, by changes the refractive power of the eye which is known as accommodation. In human eye the accommodation is due to change the refractive power of the lens (from 20 diopters to about 34 diopters), especially in children or the young person. The ability of eye accommodation (lens refractive power) is reduced with increased of age, and than followed by presbyopia.
NORMAL VISION AND ERROR OF REFACTION
Normal vision known as an emmetropic eye, if parallel light rays from distant objects are in sharp focus on the retina, when ciliary muscle completely relaxed. If the parallel light rays are focus behind the retina is known as hyperopia, if parallel light rays focus in the front of retina known as myopia, but if the different of the curvature of the cornea is known as astigmatism. The correction of refractive error is use of lens, concave spherical lens for myopia, convex lens for hyperopia and cylindrical lens for astigmatism.
VISUAL ACUITY
Visual acuity is the ability of the person to distinguished two bright pin point spots of light 10 meters away can barely distinguished the spots as separate entities when they are 1.5 to 2 millimeters apart. Clinical method to tested the visual acuity use the Snellen’s chart, consist of letter of different sizes placed 20 feet away from the person being tested, with the formula:
V = d/D V= visual acuity, d = distant of the person can read the letter, and D=distant of normal vision can read that letter.
FLUID SYSTEM OF THE EYE
For normal vision, the eye filled with intraocular fluid, which maintains sufficient pressure in the eyeball to keep it distended. The fluid can be divided into two portions: aqueous humor, which lies in front of the lens and vitreous humor, which is between the posterior surface of the lens and the retina. The aqueous humor is a freely flowing fluid, whereas the vitreous humor sometimes called the vitreous body, is gelatinous mass. Both water and dissolved substances can diffuse slowly in the vitreous humor but there is little flow of fluid. Aqueous humor is continually being formed and reabsorbed. The balance between formation and reabsorption of aqueous humor regulates the total volume and pressure of intra ocular fluid.
RECEPTOR AND NEURAL FUNCTION OF THE RETINA
millimeter. The central fovea only 0.3 millimeters in diameter is composed almost entirely of cones. Outer of the center fovea located by rods.
PHOTORECEPTOR
RHODOPSIN-RETINAL VISUAL CYCLEAND EXCITATION OF THE RODS
When light energy is absorbed by rhodopsin the rhodopsin begins to decompose within a very small fraction, cause photoactivation of electron, and then re-formation of rhodopsin again, which is call rhodopsin-retinal cycle. In that cycle vitamin A more important for normal vision, but if vitamin A is not enough, the night blindness occurs.
PHOTOCHEMISTRY OF COLOR VISION BY CONES
Photo chemicals in the cones have almost same to the rhodopsin at the rods. The difference is the protein portions, call the opsins (photopsins). According to the Young-Helmholtz theory, there are three type of color pigment in the cones cells (blue, green, red): blue sensitive pigment, green sensitive pigment, and red sensitive pigment. So different cones (three type of cone) are sensitive to different colors of light.
Color blindness. When a single group of color-receptive cones is missing from the eye, the person is unable to distinguish some colors from others, call color blindness. If the person loss of red cones it is called a protanope, if lacks of green called deuteranope. Red green color blindness is a genetic disorders, that at the female X chromosome. So that the color blindness almost in males.
NEURAL FUNCTION OF THE RETINA
Neural organization at the retina is more complex. The function of the neural pathways is to transmit the neural impulse from the retina (rods and cone) through the optic nerve to the brain. It is different at the peripheral retina and in the center foveal retina. That is way the center foveal retina for detail and color vision

PHYSIOLOGY OF THE EYE – Visual Pathways
dr. I Made Krisna Dinata, M.Erg
Abstract
The Visual Pathways
The visualnerve signals leave the retinas through the opticnerves. At the optic chiasm, the optic nerve fibersfrom the nasal halves of the retinas cross to theopposite sides, where they join the fibers from theopposite temporal retinas to form the optic tracts. The fibers of each optic tractthen synapse in the dorsal lateral geniculate nucleus of the thalamus, and fromthere, geniculocalcarine fibers pass by way of the optic radiation (also called thegeniculocalcarine tract) to the primary visual cortex in the calcarine fissure areaof the medial occipital lobe. Visual fibers also pass to several older areas of the brain:
From the optic tracts to the suprachiasmatic nucleus of the hypothalamus,
presumably tocontrol circadian rhythms that synchronize various physiologic changes of the body with night and day
Into the pretectal nuclei in the midbrain, to elicit reflex movements of the eyes to focus on objects of importance and to activate the pupillary light reflex
Into the superior colliculus, to control rapid directional movements of the two eyes Into the ventral lateral geniculate nucleus of the thalamus and surrounding basal regions of the brain, presumably to help control some of the body’s behavioral functions.
The visual pathways can be divided roughly into an old systemto the midbrain and base of the forebrain and a new system for direct transmissionof visual signals into the visual cortex located in the occipital lobes. Inhuman beings, the new system is responsible for perception of virtually allaspects of visual form, colors, and other conscious vision.
Function of the Dorsal Lateral Geniculate Nucleusof the Thalamus
The optic nerve fibers of the new visual system terminate in the dorsal lateralgeniculate nucleus, located at the dorsal end of the thalamus and also calledsimply the lateral geniculate body, as shown in Figure 51–1. The dorsal lateralgeniculate nucleus serves two principal functions: First, it relays visual informationfrom the optic tract to the
visual cortex by way of the optic radiation(also called the geniculocalcarine tract). This relay function is so accurate thatthere is exact point-to-point transmission with a high degree of spatial fidelityall the way from the retina to the visual cortex.
Visual Field
The field of vision is the visual area seen by an eye at agiven instant. The area seen to the nasal side is calledthe nasal field of vision, and the area seen to the lateralside is called the temporal field of vision.Each called monocular visual field . The area which are seen by two eyes is called binocular visual field
To make the visual perceptions more meaningful, thevisual images in the two eyes normally fuse with eachother on “corresponding points” of the two retinas.The visual cortex plays an important role in fusion. Itwas pointed out earlier in the chapter that correspondingpoints of the two retinas transmit visual signals todifferent neuronal layers of the lateral geniculatebody, and these signals in turn are relayed to parallelneurons in the visual cortex. Interactions occurbetween these cortical neurons to cause
interferenceexcitation in specific neurons when the two visualimages are not “in register”— that is, are not precisely“fused.”
Case
A woman, 65 yo, came to physician with complainthat hervisual doesn’t work properly. The examination found that she had bipolar hemianopia.
Learning Task
Which area in visual pathways had been damage in that patient? Describe the transmit of visual impulse from retina to the brain What is called the monocular and binocular visual field
Differentiate the nasal and temporal visual field, and what tool for evaluation of the visual field
Describe how the visual image can be fusion

OCULAR PHARMACOLOGY
By Dr. dr. I Made Jawi, M.Kes
Abstract
topical solutions with permeation and viscosity enhancers. Also, it includes development of conventional topical formulations such as suspensions, emulsions and ointments. Various nanoformulations have also been introduced for anterior segment ocular drug delivery. On the other hand, for posterior ocular delivery, research has been immensely focused towards development of drug releasing devices and nanoformulations for treating chronic vitreoretinal diseases. These novel devices and/or formulations may help to surpass ocular barriers and associated side effects with conventional topical drops. Also, these novel devices and/or formulations are easy to formulate, no/negligibly irritating, possess high precorneal residence time, sustain the drug release, and enhance ocular bioavailability of therapeutics. An update of current research advancement in ocular drug delivery necessitates and helps drug delivery scientists to modulate their think process and develop novel and safe drug delivery strategies. Systemic administration of a drug to treat eye disease would require a high concentration of circulating drug in the plasma to achieve therapeutic quantities in the aqueous humours, with the increased risk of side effect. Three important factors have to be considered when attempting drug delivery to the eye: (1) how the blood-eye barrier (systemic to ocular) or cornea (external to ocular) is crossed to reach the site of action; (2) how to localize the pharmacodynamic action at the eye and minimize drug action on other tissues; (3) how to prolong the duration of drug action so that the frequency of drug administration can be reduced. Many of the pharmacological agents commonly used for the treatment of eye disorders have been discussed in other blocks, such as anti bacterial, anti viral, anti allergy and anti inflammation agents. A number of antibacterial antibiotics have been formulated for topical ocular use. Natamycin is the only ophthalmic antifungal in use. Autonomic agents have several uses in ophthalmology, including diagnostic evaluation of anisocoria, as adjunctive therapy in laser and incisional surgeries, and in the treatment of glaucoma. Glaucoma is a condition of the eye in which there is an increase in the intraocular pressure (IOP), causing progressive atrophy of the optic nerve with deterioration of vision. Drugs reduce IOP either by increasing outflow of aqueous humour, by decreasing aqueous production (beta-adrenergic blocking drugs, alpha-adrenergic agonists, and carbonic anhydrase inhibitors), or transiently reducing the volume of intraocular fluids (osmotic agents).

ABSTRACT / SUMMARY OF LECTURE
The eye change refractive power to focus on near object by a process call it accommodation. Emetropia is absence of refractive errors and ammetropia is the present of refractive errors.
Light rays are focused on the retina to create sharp image. The light has to pass trough refractive media of the eye such as cornea, lens and vitreous body to reach retina. Some equipment are needed to examine refraction as follows Snellen chart, Trial lenses, trial frame, pupil distance ruler, lensometer, astigmatism chart, streak retinoscopy and autorefractor. The technique used in subjective refraction is trial and errors technique, while Astigmatic Clock Dial technique and Jackson Cross Cylinder technique were used to find astigmatism of the patient. Emmetropia is term used for eye with parallel light from distant object focused on retisna without accommodation of the eye. Ametropia is condition where parallel light is not focused on retina without eye accommodation. Classification of ammetropia is myopia, hypermetropia and astigmatism.
Miopia is a refractive error in which focus for light rays from a distant object is anterior to the retina. Hypermetropia is a refractive error in which the focus of light rays from a distant object is behind the retina. Astigmatism is a refractive error that prevents the light rays from coming to a point focus on the retina because of different degrees of refraction in the various meridians of the cornea or crystalline lens. Presbyopia (“old sight”) is a physiologically blurred near vision, commonly evident soon after age 40, due to reduction in the power of accommodation.
The management of refractive errors could be glasses, contact lens and refractive surgery. Contact lens could be used to treat refractive errors, theraphy for some ocular pathologies as well as cosmetic or prosthetic use. Some complication could be developed regarding the inappropriate handle and use of contact lens, such as allergic, Keratitis and corneal ulcer.

ABSTRACT / SUMMARY
The external eye is the most crucial part of the body exposed to outside word. The normal structure and function of the healthy eye rely on homeostasis of the entire body for protection against an adverse environment. Genetic and nutrition determine the embryogenesis and growth of the eye. Intact vascular and nervous systems stable metabolism, and immune system maintains surveillance.
protected entrance for light that is to be processed by the visual pathways through the central nervous system.
Understanding the eye's innate defenses requires study of ocular histology and biochemistry and observation of many people, both healthy and ill. The practice of corneal and external eye disease builds on this understanding and extends from clinical examination to clinic-pathologic problem solving, molecular medicine, and microsurgery. The student should become familiar with ocular embryology, anatomy, physiology and biochemistry, ocular immunology, and ophthalmic pathology.
Although the protections of the eye are very strong but the eye still can also be infected by bacteria, virus, fungi, and parasites.
A detailed history and physical examination are essential to proper diagnosis of external eye infections or inflammatory etiology. The patient's chief complaint and a complete systemic and ocular history, including the presence of risk factors for infections of the external eye, should be noted. A complete eye examination should included special attention to skin of the face and eyelids, the preauricular lymph node, the globe-orbit relationship, ocular discharge, and conjunctiva and corneal morphology. Diagnostic tests are chose to differentiate between likely diagnostic entities and to assist in therapy. (eg. Antimicrobial sensitivity testing in microbial keratitis.)
Blepharitis
Blepharitis is inflammation of the eyelid
The chronic anterior blepharitis is very common cause of ocular discomfort and irritation. Involvement is usually bilateral and symmetrical. Blepharitis may be subdivided into anterior and posterior although there is overlap and both are often present. The poor correlation between symptoms and signs, the uncertain etiology and mechanism of the disease process all conspire to make management difficult.
Hordeolum and Chalazia
Hordeolum is infection of the glands of the eyelid. It could involve meibomian gland (internal hordeolum) or Zeis's or Moll's glands (external hordeolum or stye). Pain, redness, and swelling are the principal symptoms. Most hordeola are caused by staphylococcal infections, usually Staphylococcal aureus. Treatment consists of warm compresses three or four times a day for 10-15 minutes, antibiotic ointment applied to the conjunctival sac every 3 hours. If the process does not begin to resolve within 48 hours, incision and drainage is indicated.
A chalazion is an idiopathic sterile chronic granulomatous inflammation of a meibomian gland, usually characterized by painless localized swelling. Surgical excision is performed via a vertical incision into the tarsal gland from the conjunctival surface followed by curettement. Intralesional steroid injection maybe usefull for small lesions.
Conjunctivitis
Conjunctivitis is inflammation of the conjunctiva. It is the most common eye disease worldwide. There were several causes of conjunctivitis, such as bacterial, chlamydial, viral, rickettsial, fungal, parasitic, immunologic (allergic), chemical (irritative), systemic disease, secondary to dacryocystitis or canaliculitis, or unknown etiology. The important symptoms of conjunctivitis are foreign body sensation, a scratching or burning sensation, a sensation of fullness around the eye, itching, and photofobia. The signs of conjunctivitis are hyperemia conjunctiva, tearing, exudation, pseudoptosis, papillary hypertrophy, chemosis, follicles, pseudomembranes and membranes. Specific therapy for conjunctivitis depends on the causes.
Scleritis & Episcleritis
irritation or discomfort. The condition is benign, and the course is generally self-limited in 1-2 weeks. Others therapy was needed in special causes.
Scleritis is an uncommon disorder characterized by cellular infiltration, destruction of collagen, and vascular remodeling. These changes may be immunologically mediated or less commonly, the result of infection. Laboratory studies are often helpful in identifying associated systemic disease. There were 2 types of scleritis, anterior and posterior. Initial treatment of scleritis is with systemic nonsteroidal anti-inflammatory agents. If there is no response in 1-2 weeks, or if vascular closure becomes apparent, oral prednisone, 0.5-1.5 mg/kg/d, should be started.
Keratitis
Keratitis is an inflammation of cornea. The specific symptoms are pain and photophobia. Examination is often fascilitated by instillation of a local anesthetic. Fluorescein staining can outline a superficial epithelial lesion that might otherwise be impossible to see. A patient's history is important in corneal disease. A history of trauma, corneal disease, and local medications should be investigated.
Anterior Uveitis (Iritis & Iridocyclitis)
Anterior uveitis is most common and is usually unilateral and acute in onset. Typical symptoms include pain, photophobia, and blurred vision. Examination usually revealed circumcorneal redness with minimal palpebral conjunctival injection or discharge. The pupil may be miosis or irregular due to the formation of posterior synechiae. Inflammation limited to the anterior chamber is called "iritis"; inflammation involving both anterior chamber and the anterior vitreous is called "iridocyclitis".
Dry Eye Syndrome & Keratoconjunctivitis sicca
Dryness of the eye may result from any disease associated with deficiency of the tear film components (aqueous, mucin, or lipid), lid surface abnormalities, or epithelial abnormalities. Patients with dry eyes complain most frequently of a scratchy or sandy (foreign body) sensation. Other common symptoms are itching, excessive mucus secretion, inability to produce tears, a burning sensation, photosensitivity, redness, pain, and difficulty in moving the eyelid. The most characteristic feature on slitlamp examination is the interrupted or absent tear meniscus at the lower lid margin. Tenacious yellowish mucus strands are sometimes seen in the lower conjunctival fornix. The bulbar conjunctival loses its normal luster and may be thickened, edematous, and hyperemic. Diagnosis and grading of the dry eye conditions can be achieved with good accuracy using the following diagnostic methods, such as schirmer test, tear film break-up time, ocular ferning test, impression cytology, fluorescein staining, rose Bengal staining, tear lysozyme assay, tear osmolality, and lactoferrin. The treatment is according to the gradation of the dry eye.
SCENARIO
A 79-year-old woman complains of red eyes that constantly tear and burn. She also feels foreign-body sensation and reports that her vision is not clear as before. The vision varies with tear blink. She has noticed this condition over past several years. On exam find a poor tear film filled with debris.

A 35-year-old complained of pain in his left eye for several days, watery discharge, and blurred vision. He thinks he has the same symptoms before. He admits to stress on the job as well as a recent cold sore.
What is the diagnosis?
What are you looking for on fluorescein staining? What are the signs of the herpes simplex keratitis? What is the complication of herpes simplex keratitis? How should the patient be treated?
A 30-year-old man presents with severe phtophobia, pain, tearing, and decreased vision in his right eye for two days. This condition has occurred several times before. He says that it was better by using drops. On exam, his vision 20/50 in the right eye and 20/20 in the left eye. His pupil is poorly reactive on the right and miotic. The right eye is diffuse injected, especially the limbus. The anterior chamber is deep, but cell and flare are present with few fine keratic-precipitates.
What is the diagnosis?
What is the etiology of anterior uveitis?
What are differences between nongranulomatous anterior uveitis and granulomatous anterior uveitis?

ABSTRACT / SUMMARY
Glaucoma is a group of eye disorders characterized by progressive optic nerve damage causing typical visual field defects, and increase of intraocular pressure (IOP) as one of risk factors. Glaucoma can be classified into primary, secondary, congenital and absolute glaucoma. Glaucoma also can de differentiated into acute and chronic glaucoma based on their onset. Visual acuity examination, IOP measurement, Gonioscopy, Ophthalmoscopy and Visual field examination are required to establish glaucoma diagnosis. Primary acute angle closure glaucoma (PACG) occurs when sufficient iris bombe develops to cause occlusion of the anterior chamber angle by the peripheral iris. This blocks aqueous outflow and the intraocular pressure rises rapidly, causing severe pain, redness, and blurring of vision. Angle closure is likely to develop only in eyes with preexisting anatomic narrowing of the anterior chamber angle usually when it is exacerbated by enlargement of the crystalline lens associated with aging. The acute attack is often precipitated by papillary dilatation. This occurs spontaneously in the evenings when the level of illumination is reduced.
Primary open angle glaucoma (POAG) / chronic glaucoma is the most common form in blacks and whites. The chief pathologic feature of POAG is a degenerative process in the trabecular meshwork, including deposition of extra cellular material within the meshwork and beneath the endothelial lining of Schlemm’s canal. The consequence is a reduction in adequate drainage leading to a rise in intraocular pressure. The major problem in detection of (POAG) is the absent of symptoms until relatively late in the disease.
