Consider These Facts
If Your Child
- In Americans aged 12 to 54 years, the prevalence of myopia has almost doubled to over 40% in the past 30 years (Vitale et al, 2009).
- High myopia is strongly linked to a higher risk of cataracts, retinal detachment, and myopic maculopathy (Flitcroft, 2012). Increasing rates of vision impairment and blindness due to the latter are already evident in Asian countries (Iwase et al, 2006; Wu et al, 2011).
With Keratoconus the normally round cornea becomes thin and irregular (cone) shaped.
Keratoconus is a vision disorder that occurs when the normally round cornea (the front part of the eye) becomes thin and irregular (cone) shaped. This abnormal shape prevents the light entering the eye from being focused correctly on the retina and causes distortion of vision. In its earliest stages, keratoconus causes slight blurring and distortion of vision and increased sensitivity to glare and light.
Blurred side vision may be an indication of diabetic retinopathy. Blurred central vision may be an indication of diabetic retinopathy.
If detected and treated early, crossed-eyes can often be corrected with excellent results. Strabismus occurs when one or both of your eyes turns in, out, up or down, and is usually caused by poor eye muscle control. This misalignment often first appears before age 21 months but may develop as late as age 6.
This is one reason why the American Optometric Association recommends a comprehensive optometric examination before 6months and again at age 3. There is a common misconception that a child will outgrow strabismus. This is not true. In fact, the condition may get worse without treatment.
Acanthamoeba is one of the most ubiquitous organisms in the environment, but rarely causes infections. When infection does occur, however, it can be extremely serious and vision threatening.
Recently, there have been multiple reports of increasing incidence of Acanthamoeba keratitis. Co-infection with a bacterial keratitis is common both in the contact lens case and on the cornea, complicating prevention, diagnosis and treatment.
Most spots are not harmful and rarely limit vision. But, spots can be indications of more serious problems.
Spots (often called floaters) are small, semi-transparent or cloudy specks or particles within the vitreous, which is the clear, jelly-like fluid that fills the inside of your eyes. They appear as specks of various shapes and sizes, threadlike strands or cobwebs. Because they are within your eyes, they move as your eyes move and seem to dart away when you try to look at them directly.
People with hyperopia have difficulty seeing closer objects.
Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus.
Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly.
The first sign of retinitis pigmentosa is often night blindness followed by a slow loss of side vision. Retinitis pigmentosa (RP) is a group of inherited diseases that damage the light-sensitive rods and cones located in the retina, the back part of our eyes. Rods, which provide side (peripheral) and night vision are affected more than the cones that provide color and clear central vision.
Presbyopia is a natural part of the aging process of the eye. Presbyopia is a vision condition in which the crystalline lens of your eye loses its flexibility, which makes it difficult for you to focus on close objects.
Retinoblastoma (Rb) is a rapidly developing cancer which develops in the cells of the retina, the light detecting tissue of the eye. In the developed world, Rb has one of the best cure rates of all childhood cancers (95-98%), with more than nine out of every ten sufferers surviving into adulthood. Retinoblastoma is a very treatable cancer.
People with myopia have difficulty seeing objects further away. Nearsightedness, or myopia, as it is medically termed, is a vision condition in which near objects are seen clearly, but distant objects do not come into proper focus. Nearsightedness occurs if your eyeball is too long or the cornea has too much curvature, so the light entering your eye is not focused correctly.
Is a chronic or long-term inflammation of the eyelids and eyelashes. It affects people of all ages. Among the most common causes of blepharitis are poor eyelid hygiene; excessive oil produced by the glands in the eyelid; a bacterial infection (often staphylococcal); or an allergic reaction.
Astigmatism is a vision condition that occurs when the front surface of your eye, the cornea, is slightly irregular in shape. This irregular shape prevents light from focusing properly on the back of your eye, the retina. As a result, your vision may be blurred at all distances.
A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are found in persons over age 55, but they are also occasionally found in younger people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery.
The lens of the eye is made mostly of water and protein. Clouding of the lens occurs due to changes in the proteins and lens fibers. Age-related cataracts tend to form gradually.
Some symptoms of Anterior uveitis include a red, sore and inflamed eye, and a small pupil. Anterior uveitis is an inflammation of the middle layer of the eye, which includes the iris (colored part of the eye) and adjacent tissue, known as the ciliary body.
If untreated, it can cause permanent damage and loss of vision from the development of glaucoma, cataract or retinal edema. It usually responds well to treatment; however, there may be a tendency for the condition to recur.
Early diagnosis increases the chance for a complete recovery. Lazy eye, or amblyopia, is the loss or lack of development of central vision in one eye that is unrelated to any eye health problem and is not correctable with lenses.
The infectious type of Conjunctivitis, commonly called "pink eye", is caused by a contagious virus or bacteria.
Conjunctivitis is an inflammation of the conjunctiva, the thin, transparent layer that lines the inner eyelid and covers the white part of the eye.
The three main types of conjunctivitis are infectious, allergic and chemical.
