Eye trauma refers to damage caused by a direct blow to the eye. The trauma may affect not only the eye, but the surrounding area, including adjacent tissue and bone structure.
There are many different forms of trauma, varying in severity from minor injury to medical emergencies. Even in cases where trauma seems minor, every eye injury should be given medical attention.
What Causes Eye Trauma?
When the eye is hit with blunt force, it suddenly compresses and retracts. This can cause blood to collect underneath the hit area, which leads to many of the common symptoms of eye trauma.
Symptoms of Eye Trauma
Symptoms of eye trauma may include:
Treatments for Eye Trauma
Every eye injury should be given medical attention; do not touch, rub or try to remove any object in the eye. If the eye has been cut or there is an object in the eye, rest a protective shield – such as a paper cup – on the bone around your eye. Make sure there is no pressure on the eye itself. Seek immediate, professional medical attention.
In minor cases of trauma, such as a black eye from a sports injury, applying cold to the affected area can help bring swelling down, and allow the affected area to heal faster. However, even in cases where trauma seems minor, every eye injury should be given medical attention.
The best way to avoid eye trauma is to prevent it by using protective eyewear while doing things that may put them at risk. Activities include home repair, yard work, cleaning, cooking, and playing sports. In most cases of injury, people report not properly protecting their eyes – which shows that proper precautions may prevent an eye injury.
Age-Related Macular Degeneration
Age-Related Macular Degeneration
If you’ve been diagnosed with Age-related Macular Degeneration (commonly abbreviated as AMD), you’re not alone. More than 10 million people in the US are affected by this condition. In fact, it’s the leading cause of blindness in people over the age of 65.
AMD is a condition that affects the center of the retina, called the macula. The macula is the part of the eye responsible for our most acute vision, which we use when reading, driving, and performing other activities that require fine, sharp, or straight-ahead vision. Typically, changes in the macula from AMD are gradual, but in some cases, vision loss is faster and more noticeable.
There are two different types of AMD:
Dry macular degeneration: about 90% of people diagnosed with AMD have dry AMD. This condition occurs when the tissues of the macula begin to age and thin. Dry AMD is also associated with tiny yellow deposits called drusen that form beneath the retina. People with dry AMD typically experience a less severe degree of vision loss, and it develops slowly. Early AMD always starts out as dry, but in about 10% of cases it can develop into wet AMD.
Wet macular degeneration: occurs when delicate, abnormal blood vessels form under the retina. These fragile vessels leak blood and fluid beneath the retina, causing it to distort or scar. This is the reason for loss of sharp vision in people with wet AMD. Wet AMD progresses far more rapidly than dry AMD, with more severe effects—potentially including complete central vision loss. Although this type of AMD affects only about 10% of people with the disease, it is responsible for 90% of severe vision loss associated with AMD.
Risk factors for AMD
While the causes of AMD may be unknown; age, lifestyle and nutrition appear to play a role. Things like:
Dry Eye Treatment
Dry eye is the loss or reduction of the eye's ability to produce normal tears. It is one of the most frequent causes of visits to an eye care professional. A variety of factors may cause or contribute to this problem; some are age-related, some are related to the environment. It is a common and treatable condition.
Causes of Dry Eye
Diminished tear production may be associated with certain medications, such as antihistamines, birth control pills, diuretics, high blood pressure medicines, heart medicines, pain relievers, and anti-inflammatories, and certain medical conditions, such as diabetes, rheumatoid arthritis, or thyroid problems.
Signs and Symptoms of Dry Eye
Regardless of the cause of dry eye, the signs and symptoms are similiar. An eye care professional can diagnose dry eye through a comprehensive exam, observing tear flow and quality, as well as examining the ocular surface and eyelids for the following:
Dry eye is treated in a number of ways, to help soothe the symptoms or treat the underlying cause. The most common forms of treatment for dry eye include:
