Short URL: http://chandadavis.net/?p=3025
1. Choroideremia is a rare inherited disorder that causes progressive loss of vision due to degeneration of the choroid and retina. Vision loss due to choroideremia is caused by degeneration of several layers of cells that are essential to sight.
2. Amblyopia also referred to as “lazy eye,” is the most common cause of vision impairment in children. Amblyopia is the medical term used when the vision in one of the eyes is reduced because the eye and the brain are not working together properly.
3. Strabismus involves an imbalance in the positioning of the two eyes. Strabismus can cause the eyes to cross in (esotropia) or turn out (exotropia). Strabismus is caused by a lack of coordination between the eyes. As a result, the eyes look in different directions and do not focus simultaneously on a single point.
4. Cataract is a clouding of the eye’s lens and is the leading cause of blindness worldwide, and the leading cause of vision loss in the United States. Cataracts can occur at any age due to a variety of causes, and can be present at birth.
5. Glaucoma is a group of diseases that can damage the eye’s optic nerve and result in vision loss and blindness. Glaucoma occurs when the normal fluid pressure inside the eyes slowly rises.
Cataracts- when your lens’ get clouded
Glaucoma- a disease that affects the optic nerve happens when eye pressure rises
Conjunctivitis- otherwise known as pinkeye, can be bacterial or viral, only the bacterial pinkeye requires medical attention
Macular degeneration- it happens when blood vessels grow where they arent supposed to. it causes dark spots and mainly affects central vision.
Keratoconus- it affects the shape of the eye. the cornea become thinner and makes it a cone shape rather that a half circle shape.

2. Strabismus – involves an imbalance in the positioning of the two eyes. Strabismus can cause the eyes to cross in or turn out. Strabismus is caused by a lack of coordination between the eyes and the eyes look in different directions and do not focus simultaneously on a single point
3. Glaucoma – a group of diseases that can damage the eye’s optic nerve and result in vision loss and blindness. Glaucoma occurs when the normal fluid pressure inside the eyes slowly rises. However, recent findings now show that glaucoma can occur with normal eye pressure
4. Cataract – a clouding of the eye’s lens and is the leading cause of blindness worldwide, and the leading cause of vision loss in the United States. Cataracts can occur at any age due to a variety of causes, and can be present at birth.
5. Diabetic Retinopathy – (DR) is a common complication of diabetes. It is the leading cause of blindness in American adults. It is characterized by progressive damage to the blood vessels of the retina, the light-sensitive tissue at the back of the eye that is necessary for good vision
1. Myopia (nearsightedness) – People with Myopic vision usually have eyeballs that are too large for their lens and cornea to focus light properly on their retina. Eyeglasses and contact lenses can usually correct this problem.
2. Hyperopia (farsightedness) – Hyperopia vision is caused by the eyeball being too small for the lens and cornea to focus light properly on the retina. Eyeglasses and contact lenses can usually correct this problem.
3. Presbyopia (aging eyes) – As people age, they often begin to have difficulty focusing their eyes for reading or close work. It is usually corrected with reading glasses. Some people may need bifocal of trifocal lenses.
4. Astigmatism (distorted vision) – People with Astigmatism have irregularly shaped corneas. It is usually corrected with eyeglasses or contact lenses.
5. Glaucoma – This disease increases the fluid pressure inside the eye, leading to loss of side vision and eventually total blindness. The increased pressure destroys the optic nerve. With early detection, it can be kept under control with pressure reducing eye drops and surgery. Chances of developing it increase with age. There are over five million people blind from glaucoma worldwide.
Acanthamoeba Keratitis
Poor contact lens hygiene often causes this rare but serious eye infection.
Allergies
Itchy, red, swollen, tearing eyes may mean eye allergies. Get tips for relief, and read our Eye Doctor Q&A about common eye allergy symptoms.
Amblyopia (Lazy Eye)
Amblyopia (or “lazy eye”) is a vision development problem in infants and young children that can lead to permanent vision loss. Learn the symptoms, causes and treatments.
Bell’s Palsy
This condition causes sudden paralysis of one side of the face. Because of inability to blink, you may develop severe dry eye.
Blepharitis
Inflammation of the eyelids can cause chronic eye irritation, tearing, foreign body sensation and crusty debris.
1. eye herpes- a viral infection caused by the type 1 herpes simplex virus. Causes inflamation and scarring of the cornea, also referred to as a cold sore of the eye. 400,000 Americans have experienced some form of ocular herpes with 50,000 new cases a year. Ranging from a simple infection to blindness. Symptoms include swelling of the eye, tearing, irritation, eye redness and soreness and sensitivity to light.
2. Glaucoma- refers to dangerous buildup of internal eye pressure which can cause damage to the eye’s optic nerve that transmits visual information to the brain. If untreated, it can cause peripheral vision loss and eventually blindness. Open-angle glaucoma is the most common type.
3. Retinitis Pigmentosa- rare inherited disease in which the light sensitive retina of the eye slowly degenerates. Early symptoms are poor night vision and narrow field vision. During later stages, only a small area of central vision remains along with slight peripheral vision.
4. Keratoconus- Progressive eye disease in which the round cornea thins and begins to bulge into a cone like shape. This shape deflects light as it enters the eye on the way to the retina, causing distorted vision. It can occur in both or one eye and begins in the early teens or early 20s. It causes progressive nearsightedness and irregular astigmatism to develop.
5. Conjuctivitis(pink eye)- A pink eye is the most common symptom, along with itching, burning, stinging, pain, grittiness, crusting or light sensitivity. Contagious forms of pink eye are linked to bacterial or viral infections. Non contagious forms are caused by allergens. Coughing and sneezing can spread contagious pink eye. Pink eye most often affects young children.
1. Keratoconus is a condition when the normally round cornea becomes thin and develops a cone-like bulge.
2. Eyelid spasm or twitching, which is also called blepharospasm, is an abnormal, involuntary blinking or spasm of the eyelids.
3. Diabetic retinopathy is a common diabetic eye disease caused by changes in retinal blood vessels.
4. Conjunctivitis is swelling of the conjunctiva — the thin, filmy membrane that covers the inside of your eyelids and the white part of your eye (sclera).
5. Cataract is a clouding of the eye’s normally clear lens, causing vision problems.
1. Cataracts – clouded lenses
2. Glaucoma – damage to the optic nerve from too much pressure in the eye
3. Retinal disorders – problems with the nerve layer at the back of the eye
4. Conjunctivitis – an infection also known as pinkeye
5. Age-related macular degeneration (AMD) – causes central vision loss
1.Night Blindness:Night blindness is the inability to see well at night or in poor light. It is due to a disorder of the cells in the retina that are responsible for vision in dim light.It has many causes, including:Myopia,Glaucoma ,medications that work by constricting the pupil.
2.Cataracts: A cataract is a clouding of the lens in your eye. It affects your vision. Cataracts are very common in older people. Its Common symptoms are
Blurry vision,Colors that seem faded,Glare and Frequent prescription changes in your eye wear.
3.Glaucoma: It is an eye disease in which the optic nerve is damaged in a characteristic pattern. This can permanently damage vision in the affected eye and lead to blindness if left untreated. It is normally associated with increased fluid pressure in the eye (aqueous humour).
4.Myopia: It is also called shortsightedness. It is a refractive defect of the eye in which light produces image focus in front of the retina.This causes the image that one sees when looking at a distant object to be out of focus but in focus when looking at a close object.It is corrected through the use of glasses or contact lenses.
5 Hypemetropia: It is also known as farsightedness,longsightedness, is a defect of vision caused by an imperfection in the eye causing difficulty focusing on near objects. It is usually corrected by contact lenses or glasses.
Cataract-Clouding in the lens of the eye that causes restricted lighting in the eye. Occurs in old age or soon after birth. Caused by ionizing radiation exposure to the eye.
Glaucoma-When the optic nerve is damaged in a characteristic pattern. Can permanently damage eyes and cause blindness if left untreated. Usually caused by high-pressure in the eye.
Color blindness-When certain colors or perception or harder to view with the eye. Sex-linked gene, more likely to occur in males due to X chromosome. Can be inherited from a mutation.
Strabismus-Also known as lazy eye. When one eye is not matched with the other, caused by weakness in extraocular muscles. Can be corrected by surgery.
Retinopathy-Non-inflammatory related damage to the eye. Can be caused by several diseases, including diabetes and sickle cell anemia. Many types of retinopathy can result in blindness.
1. Blepharitis is a common eyelid inflammation that sometimes is associated with a bacterial eye infection, symptoms of dry eyes or certain types of skin conditions such as acne rosacea.
2. Amblyopia, also known as lazy eye, is a vision development disorder in which an eye fails to achieve normal visual acuity, even with prescription eyeglasses or contact lenses. Amblyopia begins during infancy and early childhood. In most cases, only one eye is affected.
3.Bell’s palsy is a temporary weakness or paralysis of the facial nerve known as the seventh cranial nerve. This nerve controls facial expressions, eyelid movement and the muscles of the forehead and neck.
4.A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. Cataracts are the most common cause of vision loss in people over age 40 and is the principal cause of blindness in the world.
5. Acanthamoeba eye infections in contact lens wearers are rare but serious, and they often start because of improper lens handling and poor hygiene.
1.Red or pink eye
is cused from a viris that iratas the eye and your eye makes over the natril amount of eye crust.
2.Bump on eye (any color)
papilloma, pinguecula, pterygium is a cers from viril ifecshon as well
3.Dry eyelid
blepharitis, dry skin this is coused from your eyes not making enof eye flowed.
4.Zigzag in vision
See: floater in vision, wavy lines in vision afecis the vison diretly
5.White ring around iris is a comin for some people.
1. Cataracts- the leading cause of blindness
2. Myopia- eyeballs to large for the lens and cornea
3. Hyperopia- eyeball being to small for the lens and cornea
4. Presbyopia- difficulty reading or focusing
5. Astigmatism- irregular shaped corneas
1. Pink Eye (conjuctivitis): a bacterial infection resulting in the eye to become pink due to the conjunctiva.
2. Eye stye: a condition where the hair follicle of an eyelash is inflamed, often resulting from bacteria.
3. corneal abrasion: a condition in which the the transparent corneal layer is damaged or scratched by a foreign particle such as dust, leaf particles or smoke resulting in sensitivity to light, swelling of the eyes, blurred vision, and constant tearing.
4. Keratitis: it is a painful and serious corneal disease which is caused due to fungus. The symptoms of this disease include red eyes, sudden blurred or fuzzy vision, sensitivity to light, pain inside and around the eyes, and excessive discharge from the eyes.
5. Glaucoma: a group of eye conditions that leads to damage in the optic nerve, often resulting in blindness.
1, Macular degeneration slowly destroys the macula, which is a part of the retina that allows very sharp vision (or central vision). It’s usually a gradual process and there’s no noticeable pain. It’s the leading cause of blindness in men and women over 60.
2. Cataracts is a very common disease of the eye. They are a gradually clouding of the lens; it impairs vision. Luckily, cataracts are very treatable.
3. Floaters is a condition in which tiny clumps of cells or fibers form within the vitreous humor. They cast shadows on the retina, which makes a person believe that there are small dots in their line of sight, even though the problem is within their eyes. Some floaters are harmless and disappear over time, but others are dangerous, usually because they’re the result of a retinal tear.
4. Hemianopia is the condition of blindness or reduced vision in one half of the visual field. It’s caused by damage to the optic pathways to the brain. This damage is usually caused by a stroke.
5. Glaucoma is a condition in which the optic nerve becomes damaged due to too much fluid pressure in the vitreous humor. Oral medication can help your bloodstream fix the pressure, but a lot of the time, surgery is required.
Glaucoma refers to a category of eye disorders often associated with a dangerous buildup of internal eye pressure (intraocular pressure or IOP), which can damage the eye’s optic nerve that transmits visual information to the brain.
If untreated or uncontrolled, glaucoma first causes peripheral vision loss and eventually can lead to blindness.
According to the American Academy of Ophthalmology (AAO), the most common type of glaucoma — called primary open-angle glaucoma — affects an estimated 2.2 million people in the United States, and that number is expected to increase to 3.3 million by 2020 as the U.S. population ages.
Also, open-angle glaucoma is three times more likely to affect African-Americans, compared with non-Hispanic whites in the United States, and blindness from glaucoma is at least six times more prevalent among African-Americans than non-Hispanic whites. Studies also suggest open-angle glaucoma affects Hispanics and Latinos at comparable rates to African-Americans.
Globally, glaucoma is the second leading cause of blindness (behind cataracts), according to the World Health Organization.
A pink eye is the most obvious symptom of conjunctivitis, so the term “pink eye” often is used for this common eye problem that can have many different causes.
A pink eye, along with itching, burning, stinging, irritation, pain, grittiness, crusting or light sensitivity, are all symptoms that provide clues about the type of conjunctivitis you could have.
Contagious forms of pink eye are usually linked to bacterial or viral infections. Non-contagious pink eye can occur when eye irritants such as allergens, dust and smoke are in the environment. Coughing and sneezing can spread contagious pink eye by spraying tiny droplets from infected mucus into the air. Shared towels also can be infected, as well as table tops, counter spaces and bathrooms.
Pink eye can occur in adults, but most often affects young children through epidemics that spread rapidly in classrooms and day care centers. Particularly in these communal settings, you need to take extra precautions to prevent pink eye, such as frequent hand washing by adults and children.
In fact, when pink eye symptoms are present, it’s a good idea to keep a can of disinfectant spray handy and use it often.
Because a reddish or pink eye can be a symptom of many different types of eye problems — some that can be quite serious — make sure you consult with your eye doctor.
Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision.
Keratoconus can occur in one or both eyes and often begins during a person’s teens or early 20s.
Macular dystrophy is a relatively rare eye condition that recently made headlines when Fox News commentator Glenn Beck announced he was going blind because of the disease.
Linked to inherited genetic mutations, macular dystrophy causes deterioration of the inner back lining of the eye where the retina and light-sensitive cells (photoreceptors) are found.
As the name implies, the macula of the retina is affected in macular dystrophy. The macula is the central area of the retina that contains photoreceptors responsible for central vision and color perception. When the macula is damaged or scarred due to macular dystrophy, your central vision is affected — and this can lead to blindness in some cases.
While macular degeneration generally is associated with aging eyes, an inherited form known as Stargardt’s disease can affect children and young adults.
Stargardt’s disease, also called juvenile macular degeneration, affects approximately one in 10,000 people and is characterized by central vision loss early in life. The condition sometimes is called fundus flavimaculatus, but some researchers believe a distinction should be made between the two terms, because they say each describes a different variant of the eye disease.
1. Glaucoma- An eye disease caused by increasing fluid pressure. This pressure can damage the optic nerve, which in turn can cause decreased vision or blindness in the individual.
2. Blindness- A complete loss of vision. This can be caused through a variety of reasons, such as eye problems, brain problems, diseases, genetics, or a multitude of other problems.
3. Color-blindness- A disease in which the individual has trouble discerning certain colors. This is a sex linked disease, meaning only males can get it. There are certain degrees of color-blindness, such as partially or fully color- blind.
4. Xerophthalmia- A disease in which the body cannot produce tears. This is generally associated with vitamin A deficiency. If allowed to progress, the disease can dry the eye and cause a large variety of problems, even blindness.
5. Macular degeneration- Damage to the retina resulting in a damage in central vision. This can be caused by detachment of the retina in the central area, leading to partial or full loss of vision.
Eyes diseases:
1. Cataracts are small cloudings on the eye, usually caused by either prolonged exposure to ultraviolet light, aging, or as a side effect of certain chromosomal disorders. They cloud a person’s vision and can even lead to a complete loss of vision.
2. Astigmatism is a deformation of the eye caused by build-up of aqueous humor behind the cornea. This causes a swelling and misshapenness of the eye, and can cause irritability and increased sensitivity in the eye.
3. Color blindness is an inability to see certain hues or shades of the color spectrum caused by the inheritance (in males) of a gene that impairs the cones of the eye.
4. Glaucoma is a disease of the eye caused by damage and deterioration to the optic nerve. This can lead to unresponsiveness and loss of sight in the affected eye.
5. Conjunctivitis is a disease caused by viral or bacterial infections, along with certain allergens and irritants. This disease causes a swelling and inflammation of the conjunctiva, and is usually identified by the bright red color of an eye with conjunctivitis.

2. Cataracts- where the lenses in the eyes become cloudy and vision is blurred. This is often fixed with the removal of the old lens, later being replaced with a new one.
3. Dry eye- where the eye does not produce enough tears to properly lubricate the eye. Anti-inflammatory medication can be given to treat this and cause a greater production of tears.
4. Astigmatism- the abnormal shape of the cornea which results in poor vision. This can be treated with glasses, contacts, or surgery.
5.Presybopia- the change of where an image focuses on the retina with age. The image is typically focused too far rather than right on the retina. The only ways to treat this are with corrected vision.
Cataracts- clouding of the eye’s usually clear lens and is the leading cause of blindness in the world.
Age-related macular degeneration- disease that damages the eye’s macula, located in the center of the retina, causing a loss of sharp, central vision needed for tasks like reading and driving.
Glaucoma- disease that gradually damages the optic nerve that carries visual signals from the eye to the brain.
Retinal diseases (diabetic retinopathy and retinitis pigments)- group of hereditary disorders in which the rod and cone cells in the retina deteriorate causing impaired or loss of vision.
Strabismus- refers to the condition of the eyes being misaligned so that only one eye at a time fixes on the visual target. If left untreated, it will produce monocular visual disability or blindness.
1.Amblyopia (Lazy Eye)-poor vision in an eye that did not develop normal sight during childhood. Lazy eye is also called amblyopia.
2.Astigmatism-an imperfection in the curvature of your cornea — the clear, round dome covering the eye’s iris and pupil — or in the shape of the eye’s lens, causing blurry or distorted vision.
3.Bacterial Keratitis-an infection of the cornea, often due to improper care and cleaning of contact lenses or from injury to the cornea.
4.Glaucoma-Glaucoma is a disease that damages the eye’s optic nerve.
5.Fuchs’ Dystrophy-a progressive eye disease affecting the cornea, causing certain cells to deteriorate and die off, making corneal cells swollen and cloudy.

Cataracts – clouded lenses
Glaucoma – damage to the optic nerve from too much pressure in the eye
Retinal disorders – problems with the nerve layer at the back of the eye
Conjunctivitis – an infection also known as pinkeye
Dry Eye-Dry eye occurs when the eye does not produce tears properly, or when the tears are not of the correct consistency and evaporate too quickly
1. Glaucoma
Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve.
There are 4 major types of glaucoma: open-angle, angle-closure, cogenital, and secondary. In most cases of glaucoma, intraocular pressure is is high. Open-angle glaucoma is the most common type of glaucoma.
2. Retinal detachment
Retinal detachment occurs when the retina becomes separated from the back of the eye as a result of the spreading of a small tear. Without treatments, patients can go completely blind. Retinal detachment can be classified into 2 types: primary and secondary. symptoms include: diminishing vision, floating spots or specks and flashes of light, disappearance of segment of the visual field.
3.Uveitis
This is the inflammation of a part or all of the uvea or uvela tract. The uvea includes the choroid, ciliary body and iris of the eye. It occurs when microilariae penetrate the sclera and enter the eyeball. Symptoms include: light sensitive, blurry vision, severe pain in the eye, severe redness of the eye, diminishing vision.
4.Dry Eye
If the tear production is reduced it will result in hot, dry, burning eyes. Wet eye is a reaction to the dry eye. Dry eye may be treated with isotonic artificial tears. Closure of the lacimal puncti with thermal cautery can prevent drainage of tears and the increased tear film will moisten the ocular surfaces improving dry eye symptoms.
5.Cataract
The clouding of the normally transparent lens in the eye. It lowers the degree of transparency and thus the objects seen will become blur. Cataract is a common cause of poor vision, they account for as much as 50% of the worlds mass blindness and it is one of the worlds leading causes of blindness.
1.Cataract-It is the clouding of the normally transparent lens in the eye. It lowers the degree of transparency and thus the objects seen will become blur.
2.Glaucoma-It is an ailment that includes any eye diseases which cause an increase in pressure in the eye.
3.Retinal Detachment-Retinal detachment occurs when the retina becomes separated from the back of the eye as a result of the spreading of a small tear.
4.Uveitis-This is the inflammation of a part, or all of the uvea, or uvela tract.
5.Diabetic retinopathy-It is caused by diabetes, a group of disease in which the body is unable to regulate the amount of sugar ( glucose ) in the blood.
