Common Eye Conditions

The human visual system is an amazing network of anatomical structures. Even minor changes in the structure or function of a component of the eye can significantly affect visual acuity. Because we rely so heavily on our visual system to receive and process information, it is essential to keep the eyes functioning properly. Visit your eye care provider regularly for a vision check-up to ensure any of these common eye conditions are diagnosed and treated properly.

If you experience any change in vision, visit an eye care provider immediately. An eye exam is essential to monitoring eye health, preserving your vision for life.

Age-Related

Presbyopia

As we age, our eyes—like the rest of our bodies—begin to lose flexibility and strength. When this happens to the lens of the eye and its surrounding muscles, your lens will become stiff. This makes it harder to see close objects clearly because the eyes can't focus properly. It's a...

Macular Degeneration

One of the most important reasons for regular examinations by your eye care provider is evaluate for the development of macular degeneration. According to the Bright Focus™ Foundation, this condition is the primary cause of loss of vision and blindness in older individuals ages 60 and above...

Glaucoma

Glaucoma is the second leading cause of blindness in the United States, making it an important public health priority. Although there are several factors that cause glaucoma, all types of glaucoma are characterized by damage to the optic nerve. This damage prevents the brain from receiving...

Cataracts

Many body parts begin to change as you age, and your eyes are no exception. One of the most common age-related eye changes is the development of cataracts. Although cataracts do not occur exclusively in older adults, they affect approximately half of all Americans by age 80.

Changes in Appearance

Subconjunctival Hemorrhage

Similar to a bruise under the skin, a subconjunctival hemorrhage happens when a small blood vessel located between the sclera (white portion of an eye) and the conjunctiva (lining on the surface of an eye) breaks and covers the sclera with blood. Unlike broken blood vessels located under the skin...

Pinguecula and Pterygium (Surfer's Eye)

Characterized by a yellowish raised part of the scleral conjunctiva (the lining of the white part of the eye), a pinguecula usually develops near the cornea (colored part of the eye), but does not extend past it. Similar to a callus on the skin, changes in tissues lead to the buildup of calcium,...

Cognitive and Acquired

Uveitis

Uveitis refers to the inflammation of the eye's middle layer, which consists of the iris, ciliary body, and choroid. Several fungal, viral, or bacterial infections lead to uveitis, as do certain autoimmune (systemic) and inflammatory conditions. In most cases of uveitis, however, the exact cause is...

Computer Vision Syndrome

Almost everyone uses computers in the modern world, whether for recreation, employment, education or any combination of the three. Unfortunately, our increased use of computers in almost every aspect of our lives -- even using a smartphone to make a telephone call -- requires our eyes to read a...

Strabismus

Commonly called crossed eyes, strabismus is a condition in which eyes do not work together, failing to maintain proper alignment. While one eye focuses on an object, the other does not. The failure of the eyes to work together causes double vision, and if untreated can lead to an extreme...

Sjogren's Syndrome

Pronounced SHOW-grins, Sjogren's syndrome is a disorder of the immune system, or an autoimmune disease, which causes the body's immune system to attack and harm the body's glands. Your glands are responsible for the production of saliva, tears, and other lubrication necessary for the proper...

Optic Neuritis

Also known as demyelinating optic neuritis, optic neuritis refers to the inflammation of the optic nerve due to the loss of or damage to a protective covering called myelin, which surrounds the optic nerve. The myelin is essential to the function of the optic nerve. A more general term, optic...
More

Nystagmus

Nystagmus is a vision condition characterized by repetitive, uncontrolled eye movements. These involuntary eye movements may be side-to-side, up and down, or in a circular pattern, which hinders the eyes’ ability to focus on a steady object. Individuals with nystagmus may hold their heads in...
More

Macular Hole

The condition known as a macular hole refers to a tiny break in the macula that results in blurry or distorted vision. To fully understand the condition, one must understand eye anatomy. The macula is a spot located in the center of the retina (the back portion of the eye). Located where light...
More

Eye Occlusions

An eye occlusion is a blockage in one of the arteries or veins supplying blood to the retina and/or optic nerve. These blockages can cause severe and sudden vision loss. Contact your eye care professional immediately if you experience sudden vision loss, and follow up right away with your family...
More

Astigmatism

Many correctable vision problems are caused by abnormal eye anatomy. Very few people have perfectly shaped eyes that facilitate ideal vision. Rather, most people have some degree of abnormal curvature or other anatomical irregularities that cause slight visual changes. Astigmatism is one common...

Eye Lids

Stye

A stye, sometimes spelled as "sty," is a red, painful bump near the edge of the eyelid. It may look like a pimple or abscess, and it can form on the inside or outside of the eyelid. A stye is actually a localized infection that usually disappears by itself after a few days, although in rare cases,...

Chalazion

A chalazion is the medical term for a slowly developing lump on the eyelid that occurs due to an oil gland blockage. At first, the eyelid may appear to be red, tender and swollen. After several days, the chalazion will form on the eyelid, appearing as a slow growing lump. While it is initially...

Blepharitis

Stinging, irritated eyes, and blurred vision may indicate nothing more than a case of blepharitis -- an unpleasant but, in most cases, relatively harmless condition. Blepharitis is a chronic eyelid inflammation caused by a variety of irritants and/or the inability to maintain proper eye lubrication...
More

Bell's Palsy

If you suffer from Bell's palsy, a paralysis of one side of the face caused by nerve inflammation, you may lose control over your eyelids. This eyelid paralysis can create problems for the sensitive cornea that protects the eye's lens and helps focus light waves into clear images. Fortunately, an...

Injury & Irritation

Ocular Rosacea

Ocular rosacea, an inflammation of the eye and/or eyelid, occurs in conjunction with rosacea of the skin. A chronic inflammatory condition, rosacea primarily affects the face, cheeks, forehead, and chest area. When rosacea affects the eyes and/or eyelids, the condition is known as ocular rosacea.
