Retinal Detachment: Definition, Symptoms, and Treatment

December 1, 2018 by Anne Arundel Eye Center

A retinal detachment refers to a separation of the retina – the light-sensitive membrane in the back of the eye – from its supporting layers. This serious medical condition is typically caused by trauma, diabetes or an inflammatory disorder.

Symptoms of Retinal Detachment

• Flashes of light (Especially in peripheral vision)

• Blurred/blurry vision

• Floaters in the eye. Also referred to as shadows or spots

• Blindness in a portion of the visual field

The sudden and dramatic appearance of these symptoms is a strong indication that the retina is either tearing or detaching. If you feel you may be experiencing any of the above 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.

Treatment of Retinal Detachment

Most cases of retinal detachment require one of the following surgeries.

• Freezing (cryopexy): The application of intense cold to the area with an ice probe to form a scar, which holds the retina in place.

• Laser Surgery (photocoagulation): This is used to seal the tears or holes in the retina.

• Pneumatic Retinopexy: The placing of a gas bubble in the eye to help the retina float back into place. Then a laser is used to fix the retina in place.

More extensive cases require more invasive procedures, including:

• Scleral Buckle: This is done to indent the wall of the eye, relieving the tugging of the vitreous on the retina.

• Vitrectomy: This is done to remove gel or scar tissue that may be pulling on the retina.

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.

Eye Floaters, Flashes and Spots

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. Read the full article here: anti-viral-meds.com

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.

Your Cornea: Conditions, Symptoms and Treatments

An Overview of the Different Types of Glaucoma

October 11, 2016 by Anne Arundel Eye Center

The term Glaucoma actually refers to a group of eye conditions that lead to intraocular pressure (IOP) and damage the optic nerve, the nerve that carries visual information from the eye to the brain. This pressure comes from a buildup of normal fluid called the aqueous humor, which is naturally and continuously produced in the front of your eye.

The different types of glaucoma include:

Primary Open-Angle Glaucoma: Affecting around one percent of all Americans (mainly those individuals age 50 or older), it is the most common form of glaucoma. And because this form of glaucoma develops slowly, it rarely ever presents any symptoms and often goes undetected without regular screenings.
Normal Tension Glaucoma: Also known as Low-Tension Glaucoma, this form is characterized by progressive optic nerve damage and visual field loss with a statistically normal IOP. The lack of blood flow and the decrease in oxygen to the optic nerve is directly related to this form of glaucoma.
Angle-Closure Glaucoma: This form of glaucoma is related to narrow angles. And with several subcategories – including Intermittent and chronic Acute Angle-Closure or Narrow Angle-Closure – this form affects nearly 500,000 Americans, but is most common in people of Asian descent or those individuals with farsightedness (hyperopia). Unlike POAG where the IOP increases gradually, Angle-Closure Glaucoma is characterized by a sudden increase in IOP, often in only a matter of hours. This dramatic increase in IOP can cause severe eye pain, nausea, vomiting, blurry vision and headache. An acute attack is an emergency condition. Long-term effects of Angle-Closure Glaucoma include: scarring of the trabecular meshwork, resulting in chronic glaucoma; cataracts; damage to the optic nerve; permanent vision loss.
Pigmentary Glaucoma: This form is a type of inherited open-angle glaucoma, which develops more frequently in men than in women and is most prevalent in individuals in their twenties and thirties. Pigmentary Glaucoma is associated with near-sightedness (myopia).
Trauma-Related Glaucoma: A blow to the eye, chemical burn, or penetrating injury may lead to the development of either acute or chronic glaucoma.
Childhood Glaucoma: Also referred to as Pediatric Glaucoma, the approach to treatment is slightly different than with glaucoma in adults and almost always requires immediate surgery to relieve IOP. Approximately 80-90 percent of babies who receive prompt surgical treatment, long-term care, and monitoring of their visual development will do well, and may have normal or nearly normal vision for their lifetime. However, if the disease is not caught early more permanent vision loss will result.

The most common symptoms of glaucoma include:

Vision loss (most commonly tunnel vision – the gradual loss of peripheral or side vision)
Severe eye pain
Nausea and vomiting
Sudden onset of visual disturbance
Blurred or blurry vision
Halos around lights
Reddening of the eye

If you feel you may be experiencing any of these symptoms, schedule an appointment with your eye doctor immediately. These symptoms are serious and require prompt medical attention from your optometrist or ophthalmologist.

However, many people do not experience any symptoms until they begin to lose their vision. At this point, the damage is irreversible. This is why regular eye exams are so important. While there is no cure for glaucoma, early detection and treatment are your best options to slow or even prevent further vision loss brought on by the disease. Without treatment, glaucoma can lead to permanent vision loss.

Glaucoma is the second-leading cause of vision loss in the United States behind only cataracts.

Keratoconus Signs and Symptoms :: Keratoconus Treatment Options in Maryland

May 24, 2012 by Anne Arundel Eye Center

Keratoconus is a degenerative eye disorder affecting the shape of the cornea, the clear structure covering of the front of the eye (similar to the glass faceplate on a watch). Over time, in Keratoconus, the normally round cornea begins to bulge into a cone-like shape, deflecting light entering the eye and causing distorted vision.

The cause of Keratoconus is currently unknown, although several researchers believe allergies and excessively rubbing one’s eyes may play a role.

Signs and Symptoms of Keratoconus

The cornea becomes more irregular in shape
Subtle blurring of the vision
Causes progressive nearsightedness and irregular astigmatism
Glare and light sensitivity may occur
Frequent changes in eyeglass prescription

If you are experiencing 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.

Keratoconus Treatment

The primary treatment option for Keratoconus patients remains the use of contact lenses, including:

Custom soft contact lenses specially designed to correct mild-to-moderate forms of this eye disease.
Rigid gas permeable (RGP or GP) contact lenses, which, with their rigid shape, replace the irregular shape of the cornea with a smooth refracting surface.
Some eye care professionals recommend “piggybacking” two different types of contact lenses on the same eye to increase the wearer’s comfort.

Other Keratoconus treatment options include:

Collagen cross-linking, which is still in clinical trials, is a technique that uses UV light and a photosensitizer to strengthen chemical bonds in the cornea to halt progressive and irregular changes in corneal shape.
Severe cases of Keratoconus may require corneal transplantation. Still, even after a transplant, you will likely need glasses or contact lenses for clear vision.

Your eye doctor will be able to better inform you of your treatment options.

More on Corneal Collagen Crosslinking: The Methods

Collagen crosslinking, an investigational treatment in the United States, was first performed in Europe in the late 1990s for the treatment of ectatic corneal conditions. The treatment combines riboflavin and ultraviolet A (UVA) light, allowing the formation of reactive oxygen species, with the goal of halting the progression of corneal disease.[1-4]

For riboflavin to act as a catalyst in this process, it must first be absorbed into the corneal stroma. Because the corneal epithelium acts as a barrier to riboflavin absorption, it can be removed before treatment with UV light.

The Dresden technique, or “epi-off” crosslinking, is initial removal of the central 9 mm of epithelium, followed by 30 minutes of riboflavin administration. Subsequently, UVA light is applied for 30 minutes, followed by bandage contact lens placement. Epi-off crosslinking can be effective in reducing keratometry readings.[1,3-5] The potential risks of this procedure include initial worsening of vision in the first month, pain, haze, corneal melt, and infection.[6]

Dr. Brian Boxer Wachler was the first to perform transepithelial crosslinking, or “epi-on” crosslinking, in 2004. Because the epithelium is not removed, riboflavin loading requires more time than with epi-off techniques. Epi-on crosslinking has several distinct advantages: faster visual recovery; reduced pain; and reduced risks for delayed epithelial healing, infection, and visually significant corneal haze.
