Flashers and Floaters in the Eye: What are They and What do They Mean?

November 22, 2018 by Anne Arundel Eye Center

As we age, the eye’s gel-like vitreous begins to dissolve and liquefy, creating a watery center. Occasionally some un-dissolved vitreous particles will float around the now watery center, appearing as spots or what we refer to as floaters.

Floaters in the eye are a fairly common, harmless apparition that will generally fade away in time. Yet, while these floaters are typically common, they can be the first signs of a more serious medical condition, such as retinal detachment.

If you ever see a shower of floaters (spots) accompanied by flashes of light (photopsia), then you should seek immediate medical attention. The sudden and dramatic appearance of these symptoms could indicate that the retina is either tearing or detaching.

Retinal detachments and retinal tears are both emergency conditions that require immediate medical attention. An eye surgeon must reattach or repair the retina to prevent permanent vision loss from occurring.

So if you see floaters in your eye, schedule an appointment with your eye doctor – optometrist or ophthalmologist – at your earliest convenience. Any change in your sight is a serious medical condition that requires prompt attention. If these symptoms appear rapidly and include flashes of light, call your eye doctor right away.

Corneal Disease: Explanation, Symptoms, and Treatment

October 10, 2017 by Anne Arundel Eye Center

Your cornea – the clear, protective outer layer of the eye – not only protects your eye from dirt and germs, but also plays a key role in your vision. As light enters the eye, it is focused or refracted by the shape of the cornea. If your cornea sustains damage through disease, infection or injury, the resulting scar tissue can interfere with your vision by blocking or distorting light as it enters your eye.

There are several different conditions including infections, degenerations and other disorders that affect the cornea. These include:

Astigmatism: Caused by an irregularly shaped cornea, astigmatism is a refractive error in which the eye has trouble focusing light. Astigmatism is the most common form of corneal problem. Treatment typically involves the use of glasses or contacts.

Corneal Abrasion: Caused by trauma to the eye, a corneal abrasion refers to a scratch on the outer layer of the eye. It is the second most common form of corneal distress. Treatment traditionally involves patching of the eye, though newer bandage contact lenses are beginning to see more use. These allow people to stay functional during the healing process.

Keratits: This form of corneal disease is an inflammation of the cornea that occurs with viral, bacteria or fungal infection. Symptoms of keratitis include severe eye pain, reduced visual clarity, and discharge.

Ocular Herpes (Herpes of the Eye): Similar to cold sores on the lip, this reoccurring viral infection produces sores on the surface of the cornea that, in time, can spread deeper into the cornea and eye. There is no cure for ocular herpes, but it can often be controlled with the use of antiviral drugs. You can also try using Valtrex. Valtrex (Valacyclovir) is an antiviral medication used to treat infections caused by certain viruses. It helps the body fight infection by slowing the growth and spread of the herpes virus. It is used to treat shingles (caused by herpes zoster), genital herpes, and cold sores around the mouth. Valtrex is also a treatment for cold sores in children over the age of 12 years old and as a chickenpox medication in children who are over the age of 2 years.

Herpes Zoster (Shingles): This is actually a recurrence of the chickenpox virus, since most of us have already had the disease. Symptoms of Herpes Zoster include blisters or lesions on the cornea, fever, and pain from inflamed nerve fibers.

Corneal Dystrophies

There are over 20 of these diseases that cause structural problems with the cornea. The most common forms include:

Keratoconus: This is a progressive disease in which the cornea thins and even changes shape, creating either mild or severe distortion (astigmatism) and nearsightedness (myopia).

Map-Dot-Fingerprint Dystrophy: As the basement membrane of the epithelium of the cornea grows irregularly, abnormalities resembling maps, dots and fingerprints form in the cornea. While this form of corneal disease is mostly painless and causes no vision loss, epithelial erosion may occur, exposing the nerves lining the cornea and causing severe eye pain.

Fuchs’ Dystrophy: Seemingly happening for no apparent reason – although you may have a genetic predisposition to the disease – Fuch’s Dystrophy involves the gradual deterioration of endothelial cells. As these cells thin, they can no longer remove water from the corneal stroma. This causes the stroma to swell and distort vision.

Lattice Dystrophy: This disease is characterized by the presence of abnormal protein fibers throughout the stroma. This can result in the clouding of the cornea and reduced vision and in rare cases, epithelial erosion.

Symptoms of Corneal Disease

The cornea has the ability to quickly repair itself after most injuries or diseases. However, more serious situations may result in a much more prolonged healing process. If this is the case, the following symptoms should serve as an immediate indicator of a deeper medical issue:

Eye pain
Blurred/blurry vision
Tearing
Redness
Extreme sensitivity to light
Corneal scarring

If you feel you may be experiencing any of these symptoms, schedule an appointment with your eye doctor immediately. Any sudden change in your vision is a serious medical condition that requires prompt medical attention from your optometrist or ophthalmologist.

Although corneal disease resulting from hereditary factors cannot be prevented, infectious corneal disease caused from bacteria and viruses can be avoided. You should never share eye makeup, contact solution, lens cases, and eye drops with anyone as this may increase the risk of infection.

However, if you do contract some form of corneal disease, vision can be preserved through early detection and treatment. This is just another reason why regular eye exams are so important.

Age-Related Macular Degeneration: Symptoms and Treatment

December 22, 2011 by Anne Arundel Eye Center

Age-related macular degeneration (AMD) is the leading cause of vision loss and blindness in Americans 60 years of age or older. Currently, about 1.75 million U.S. residents have advanced AMD with associated vision loss. That number expected to grow to almost 3 million by 2020.

AMD is an eye disease that affects the part of the retina (the macula) responsible for sharp, central vision. As a result, AMD can make it difficult to perform every day tasks, such as reading and driving.

Symptoms of Age-Related Macular Degeneration

Gradual loss of ability to see objects clearly
Objects appear distorted in shape. Straight lines look wavy or crooked.
Loss of clear color vision
A dark or empty area appears in the center of vision.

If you feel you may be experiencing any of the above symptoms, schedule an appointment with your eye doctor as soon as possible. Any sudden change in your vision is a serious medical condition that requires prompt medical attention from your optometrist or ophthalmologist.

AMD can advance so slowly that individuals initially notice little change in their vision. Other times, AMD progresses more rapidly and may even lead to vision loss in both eyes. This is why regular eye exams are so important. They can help detect the eye disease before it causes significant vision loss.

Age-Related Macular Degeneration Treatment

There are two types of AMD, “dry” macular degeneration and the less common “wet” macular degeneration.

Dry AMD: With this form of AMD, the tissue of the macula gradually becomes thinner and stops functioning properly. There is currently no cure for dry AMD and any vision loss associated with the disease cannot be restored, even with treatment.
Wet AMD: This form of AMD is caused by fluid that leak from newly formed blood vessels under the macula, resulting in blurred central vision. With wet AMD, vision loss can be rapid and severe, but if detected early, this form of AMD can be treated with photocoagulation (laser treatment).
Other potential treatment options include:
Anti-angiogenesis drugs: These medications block the development of new blood vessels and leakage from the abnormal vessels within the eye that cause wet macular degeneration.
Vitamins: A recent study found that vitamins C, E, beta carotene, zinc and copper can decrease the risk of vision loss in patients with intermediate to advanced dry macular degeneration.

Photodynamic laser therapy: A two-step treatment in which a light sensitive drug is used to damage the abnormal blood vessels. A doctor injects the drug into the bloodstream to be absorbed by the abnormal blood vessels in the eye. The doctor then shines a cold laser into the eye to activate the drug, damaging the abnormal blood vessels.

While AMD treatment cannot restore your vision, it can help to slow further vision loss.

The Importance of Regular Eye Exams

December 8, 2011 by Anne Arundel Eye Center

Regularly scheduled eye exams – regardless of your age or physical fitness – are an important part of your overall health, not just your vision.

Eye exams for adults are needed to keep your eyeglasses prescription current. Even if you primarily wear contact lenses, having a current eyeglasses prescription is still very important. If something were to happen to your contacts,it is necessary to have a pair of up-to-date backup glasses handy. During your eye exam, your eye doctor will also check for early signs of eye disease and other health-related disorders. Did you know that eye doctors (optometrists orophthalmologists) are often the first healthcare professionals to detect chronicsystemic diseases, like high blood pressure or diabetes?

Eye exams for children, meanwhile, are important for normal vision development and academic achievement. Vision is closely linked to the learning process and poor vision will often result in poor academic performance. And since the effected child does not know what normal vision looks like, he/she is unable to articulate the problem to their teachers or parents. That is why regularly scheduled eye exams are important even if your child does not complain of poor or blurry vision.

What does an Eye Doctor Check for during an Eye Exam?

Your eye doctor will not only evaluate your prescription for eyeglasses or contact lenses,but he/she will also inspect your eyes for common eye diseases and other problems thatcould lead to vision loss. Your eye

doctor will look for the following:

Refractive Errors: These errors, which include nearsightedness, farsightedness, andastigmatism, are corrected with eyeglasses, contacts, or eye surgery.

Glaucoma: The term Glaucoma refers to a group of eye conditions that lead to damage the optic nerve, usually resulting from a rise in intraocular pressure (IOP). The optic nerve carries visual information from the eye to the brain.

Cataracts: A cataract is clouding of the eye’s lens, which is located behind the iris and pupil. Cataracts do not damage the health of your eye in any way; they just result in blurry vision.

Amblyopia: This occurs when one eye has a much different prescription than the other or when the eyes are turned, resulting in the brain “shutting off” the image from the effected eye. Failure to address this disorder can result in permanent vision loss. Amblyopia is often treated with drops or by patching the stronger eye for a period of time.

Strabismus: Also known as crossed eyes or turned eyes, Strabismus can cause problems with depth perception and can even lead to Amblyopia.

Corneal Disease: There are several different conditions including infections, degenerations and other disorders that affect the cornea.

Diabetic Retinopathy: This is the most common progressive eye disease resulting from long-term diabetes.

Why Are Eye Exams Important?

November is National Diabetic Eye Disease Month

November 4, 2011 by Anne Arundel Eye Center

There are roughly 29 million Americans that suffer from diabetes, about 8% of the total population. And because diabetes presents with few symptoms, almost a third of these individuals are unaware they have the disease.

Without knowing they are diabetic, this 1/3 is at an increased risk to develop Diabetic Retinopathy, the leading cause of blindness in American adults. They are also over 40% more likely to develop glaucoma, the second-leading cause of vision loss in U.S. And because diabetic retinopathy and glaucoma rarely presents any symptoms, regular eye exams and early detection remain your best options for fighting these diseases.

This is why November was named National Diabetic Eye Disease Month.

The longer these diseases go untreated, the more likely they will result in permanent vision loss. Because of this, it is extremely important for those with diabetes to not only seek regular medical care, but also regular eye exams (at least once a year), as well. If caught early enough, Diabetic Retinopathy and Glaucoma are treatable.

If you do experience any symptoms – like blurred/blurry vision – schedule an appointment with your eye doctor immediately. If this change in vision is extreme or if any eye pain is involved, consider having a family member or friend drive you to the emergency room.

Any change in your sight is a serious medical condition that requires immediate attention.
