Lazy Eye (Amblyopia): causes and symptoms

September 3rd, 2010

Amblyopia, also known as lazy eye, is a unique disorder. It is a poor vision in an eye that did not develop normally during childhood. It commonly affects one eye but may also involve both eyes.
- It is not correctable by glasses or contact lenses.
- It is not due to any eye disease.
- The brain does not fully acknowledge the images seen by the amblyopic eye.

Causes of Lazy Eye

Amblyopia is caused by various conditions which prevent the brain from using both eyes together.
- Constant strabismus : it is the constant turn of one eye.
- Anisometropia : It is the different vision or prescriptions in each eye.
- Blockage of an eye due to cataract, trauma, lid droop, etc.
- A condition in which the brain to avoid double vision ignores the image from the deviating eye which leads to poor visual development.
- Amblyopia can occur due to the causes for stimulus deprivation like ptosis, cataract, glaucoma, patching or any other obstacle that blocks the vision in the eye.

Signs and Symptoms of Lazy Eye

- A lazy eye is not always easily recognized.
- A child may not even be aware that one of his eyes is not working with the other.
- Photographs that show milky white spots in a child’s eye, rather than the more common red spots, may indicate the early development of cataracts.
- If your child routinely closes one eye while reading or watching the television, the vision in that eye may be impaired.
- If your child is not performing well in school, consult an eye-doctor before questioning his/her learning ability.
- Consult an eye doctor if your child’s eyes don’t appear to be working in unison when he or she focuses on an object.
- Avoidance of activities such as athletics or indoor activities such as reading or coloring may be a sign of vision problems.

September 1st, 2010

Blepharitis is the inflammation of the eyelid margins that causes severe discomfort to a person. The disorder usually starts in childhood and may continue throughout life. It causes red, irritated, itchy eyelids, and the formation of dandruff-like scales on the eyelashes.

Types of Blepharitis

- Anterior blepharitis : It affects the area where the eyelashes are attached i.e. the outside front of the eyelid.
- Posterior blepharitis : The moist inside part of the eyelid is affected. It is caused by problems with the Meibomian glands in this part of the eyelid.

Causes of Blepharitis

- Blepharitis frequently occurs in people who have a tendency toward oily skin, dandruff or dry eyes.
- Blepharitis occurs when the small oil glands near the base of the eyelashes don’t work properly.
- The cause is overgrowth of the bacteria that is normally found on the skin.
- Blepharitis is usually caused by seborrheic dermatitis or a bacterial infection, and sometimes it is a combination of both.
- Allergies and eyelash infestation with lice may also cause blepharitis.

Symptoms of Blepharitis

- Watering of eyes.
- Whitish and yellowish material deposits at eyelid margins.
- Burning, itching in eyes.
- In some extreme cases, lid margin gets thickened.
- Falling of eyelashes but it is replaced quickly.

Bladder Cancer – Symptoms – 2 types of Bladder Cancer

August 22nd, 2010

Bladder cancer is of two types. Invasive bladder cancer and superficial bladder cancer. Superficial bladder tumors usually appear on the urinary epithelium in the form of bladder warts, papillomas or papillary tumors. Invasive tumors as the name suggests appear deeper in the urinary epithelium. In some cases they may extend into the surrounding tissues or muscle layers. They may also spread into near by organs like the sigmoid colon, prostate gland, rectum, uterus, bones of the pelvis and the lymph glands.
Bladder cancer is more common in men as compared to women and is usually diagnosed around the age of 65. Cigarette smoking is one of the main causes of bladder cancer. Exposure to cancer causing substances used in synthetic dyes, rubber, leather, cable and printing may also by high risk causes.

Symptoms: Bladder cancer can be very painful and if one experiences the following symptoms, you should get it checked immediately:

- Hematuria – blood in the urine
- Burning sensation or pain while urinating when you are not suffering from any kind of urinary tract infection.
- A radical change in bladder habits. Often you may want to use the toilet because of a strong urge to urinate but you may not produce too much urine.

These symptoms do not necessarily suggest that you may be suffering from bladder cancer. They are non specific and could be an indication of something else altogether. However if you are suffering from any of the above mentioned symptoms, you should consult a doctor right away.

Old men who experience blood in the urine and are heavy smokers should consult a medical professional immediately as smokers are at high risk of getting bladder cancer. Blood in the urine is the first warning sign and it should not be ignored.
However it is also important to note that the blood in the urine is often not visible to the naked eye. A simple urine test can prove the presence of microscopic hematuria. You can also know for a fact that there is blood in your urine, if it changes color. If your urine takes on a pinkish or orange color, it’s a sign of hematuria.
Like many other cancers, even bladder cancer is difficult to detect and causes little or no symptoms till it has reached an advanced stage. At an advanced stage it is difficult to cure and can be very painful. People who are smokers are usually at a higher risk and as they age they should speak to their doctors and consider going in for regular cancer screening to check whether they are alright.
These are just a few symptoms of bladder cancer. The condition can be very painful if left undetected. However it is difficult for an individual to understand that he or she is suffering from bladder cancer as the symptoms take too long to surface.
However it is essential that every individual as they age should keep a track on their lifestyle, avoid smoking and drinking and also follow a good diet and exercise regimen if they want to stay healthy. A sedentary lifestyle will only make the condition worse. People who are smokers should keep an eye out for the signs and should not waste any time if any of the symptoms surface. Tests and trips to the doctor may cost you some money but it is worth it if the cancer is detected at an early stage. Treating the cancer at a later stage is difficult and can cause a lot of pain to the entire family, therefore staying precautious is the only way of staying safe and healthy.
