The lens within the eye is initially composed of crystaline proteins that are transparent. As one ages these proteins harden and opacify and lead to a reduction of vision and a common symptom of glard. Most cataracts are age related, affecting those from 50-90 years of age. However, cataracts can also be caused by trauma, radiation, and medications. There can be a genetic component. When symptomatic treatment is accomplished with lens removal and placement of an Intraocular lens to restore vision.
Glaucoma is a leading cause of blindness and visual impairment in the United States. Glaucoma, known as the "sneak thief of sight," can affect patients of all ages. Many people affected with glaucoma do not experience any symptoms and may not be aware that they have the disease until they have lost a significant amount of vision. With early detection and treatment, eyes can be protected against the serious loss of vision or blindness.
Macular degeneration, also known as age-related macular degeneration (AMD) is a common condition in older adults and the leading cause of vision loss in people over the age of 50. Macular degeneration affects the macula, the part of the retina responsible for the crisp, detailed central vision needed for reading or driving. As we age, the tissue in the eye responsible for vision slowly begins to deteriorate which can significantly affect a patient's quality of life.
Dry eye is a common condition that occurs when the eyes are insufficiently moisturized, leading to itching, redness and pain from dry spots on the surface of the eye. The eyes may become dry and irritated because the tear ducts don't produce enough tears, or because of a chemical imbalance in the tears.
This is a disorder affecting regulation of blood sugar. The major long-term complications of diabetes are due to damage of blood vessels. Specifically the blood vessels around the eyes, heart, kidney, and peripheral nerves. In short the blood vessels leak causing diabetic retinopathy, which is the leading cause of blindness in adults.
Flashes and Floaters
While flashes and floaters occur in most people with healthy or merely nearsighted eyes, they can be symptoms of more serious problems that occur as a result of injury or retinal and posterior vitreous detachments.
- Flashes in vision are caused by pressure on the retina, the bundle of nerves in the back of the eye where images are detected and transmitted to the brain. Patients who have flashes in vision complain of seeing flashing lights or lightning streaks.
- Floaters are seen when fibers move within the vitreous humor, the gelatinous substance made of water and protein fibers that fills the eye. Patients symptoms include seeing small specks or dots that against clear backgrounds. Serious vision loss can occur if the retina or vitreous detach within the eye.
Blepharitis is the chronic inflammation, or infection, of the eyelids and the eyelash follicles along the edge of the eyelid. Blepharitis, which is not contagious, affects patients of all ages. There are several reasons for the occurrence of blepharitis, some of them are: Seborrheic dermatitis, Acne, Bacterial infection, Allergic reaction, Poor eyelid hygiene, and Rosacea.
Over 35 million Americans wear contact lenses, according to the American Optometric Association. Unlike glasses, contact lenses move with your eyes so you can enjoy a larger field of vision with fewer distortions. You also don't have to deal with frames hovering in your peripheral vision or external lenses that fog up on cold days or get wet in the rain. There are many different kinds of contacts, including: Rigid gas permeable, Extended wear, Disposable wear, Daily-wear, Bifocal or multifocal.
Allergic Eye Disease
Allergic conjunctivitis is the inflammation and swelling of the tissue lining the eyelids and the white of the eye, the conjunctiva, in reaction to allergy causing conditions. The allergy may be seasonal, often occurring alongside hay fever, or it may occur throughout the year, known as perennial, as a result of exposure to allergens such as dust mites, mold or animal dander.
A vision condition that imparts blurred vision due to either the irregular shape of the cornea or lens within the eye, This can be corrected with spectacles, hard contact lens, or a specialized toric soft contact lens. It can also be corrected surgically.
A vision condition which imparts blurred near vision requiring use of reading spectacles. This is typically age related and most noticeable starting at age 40-45. Anatomically this is due to a changing electricity of the crystaline lens and loss of muscle strength.
