Warning signs of a serious eye problem

Eyes aren't exempt from the wear and tear of aging. Some of the age-related changes in the eyes are annoying but not serious — for example, it can become difficult to focus on near objects, and eyelashes may thin out a bit. But other changes can threaten vision.

With age, the eyes' ability to stay lubricated starts to wane. This can leave eyes feeling irritated, sticky, dry, or gritty. The lens of the eye can become less elastic. Night vision may also start to suffer, which can pose problems when driving at night. In contrast, cataract, macular degeneration, and diabetic retinopathy can rob you of your sight.

Product Page - The Aging Eye
As the eyes age, problems with vision become more common. Learn how to recognize the risk factors and symptoms of specific eye diseases — cataract, glaucoma, age-related macular degeneration, and diabetic retinopathy — and what steps you can take to prevent or treat them before your vision deteriorates.

A new study found that between 1998 and 2013, the rate of bicycle injuries rose by 28% and the rate of people admitted to the hospital because of bike injuries rose by 120%.

5 truths about protecting your eyes

Of your five senses, which one are you most afraid of losing? If you're like most people, your answer is your ability to see. Because our eyesight is so precious, it's no wonder that myths abound about what can damage our eyes — and what can protect them. Here, we debunk five common myths — and tell you how to truly keep your eyes healthy.

Myth: Doing eye exercises will delay the need for glasses.

Fact: Eye exercises will not improve or preserve vision or reduce the need for glasses. Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly altered with eye exercises.

Myth: Reading in dim light will worsen your vision.

Fact: Dim lighting will not damage your eyesight. However, it will tire your eyes out more quickly. The best way to position a reading light is to have it shine directly onto the page, not over your shoulder. A desk lamp with an opaque shade pointing directly at the reading material is ideal.

Myth: Carrots are the best food for the eyes.

Fact: Carrots, which contain vitamin A, are indeed good for the eyes. But fresh fruits and dark green leafy vegetables, which contain more antioxidant vitamins such as C and E, are even better. Antioxidants may even help protect the eyes against cataracts and age-related macular degeneration. Just don't expect them to prevent or correct basic vision problems such as nearsightedness or farsightedness.

Myth: It's best not to wear glasses or contact lenses all the time. Taking a break from them allows your eyes to rest.

Fact: If you need glasses or contacts for distance or reading, use them. Not wearing your glasses will strain your eyes and tire them out instead of resting them. However, it will not worsen your vision or lead to eye disease.

Myth: Staring at a computer screen all day is bad for the eyes.

Fact: Using a computer does not damage your eyes. However, staring at a computer screen all day can contribute to eyestrain or tired eyes. People who stare at a computer screen for long periods tend not to blink as often as usual, which can cause the eyes to feel dry and uncomfortable.  To help prevent eyestrain, adjust the lighting so it doesn't create a glare or harsh reflection on the screen, rest your eyes briefly every 20 minutes, and make a conscious effort to blink regularly so that your eyes stay well lubricated.

The Process Of Prostate Cancer Staging

By Nancy Gardner

Staging of tumors helps the doctor to tell how extensive the disease is. However, several scans have to be done and tests carried out for a proper diagnosis. From the results, management plans can then be drawn. This is why professionals in the medical field emphasize on prostate cancer staging.

The cancer of the prostate is staged using TNM stages. This is in the international standard of staging. It assesses the tumor, lymph nodes and the degree of spread. If the tumor is said to be in T1, it means that the area affected is too small and thus a diagnosis cannot be made through palpation or scans. A needle biopsy has to be done in order to pick this up.

Tumors in stage T2 are classified into three categories. The first one is T2a which indicates that only one lobe of the prostate gland is affected. In T2b, more than half of gland is affected and in T2c stage the entire lobe is affected. On the other hand, if the tumor has left the prostate gland to affect the capsule but has not spread further is said to be in stage T3. This stage has two categories. T3a and T3b where the malignancy has reached the capsule and seminal vesicles respectively.

The final stage in tumor classification is T4 stage in which the tumor is found in various body organs. The nearby organs are mostly affected including the rectum, muscles, bladder and the pelvic cavity sides. The fourth and third stages are the most difficult to manage.

In lymph node staging, the guiding factor is the severity of the condition in the lymph nodes. They are said to be positive if they contain cancer cells. This makes them to swell. In NX stage, it is not possible to check them and in N0 stage the lymph nodes adjacent to the prostate have no cancer cells. However, in N1 stage, the malignancy has reached the lymph nodes.

When classifying according to the degree of spread, the first stage is M0 which signifies that the tumor is confined just within the pelvis. In M1, the cancer has finally got out of the pelvis. It has sub stages. The first one is the M1a where the lymph nodes next to the pelvis have been affected and M1b means the skeletal system has been affected by the tumor. In M1c, the malignancy has eventually spread to the rest of a body. A couple of factors are considered in doing the staging.

Locally advanced type of prostate cancer extends just to the capsule of this gland but the metastasizing type spreads to many of body organs. Mainly, the victims of this spread are the bones and lymph nodes. This is why early detection is stressed to prevent such complications.

Metastasis can occur when the tumor is still in its initial stages. That is why people are advised to regularly go for blood tests and scans for early diagnosis. If some cancerous cells are found in other body organs, immediate action should be taken to control the spread.
