The symptoms of strabismus are somehow clear-cut and you can ordinarily tell is a person has it by just observing their eyes. The condition also known as squint, lazy eye, crossed eye, boss eye, cock eye and wall eye. It is marked by eyes that are not correctly aligned with each other, because of lack of coordination of the extraocular muscles that manipulates the movement of the eye. Here are the symptoms of strabismus that can help you tell if the person is affected by the condition.
One of the symptoms of strabismus is that the eyes are not able to look in the same direction concurrently. The reason for this is that the extraocular muscles may be weak and therefore are unable to coordinate the movement of the eyes. This brings about to an impaired binocular vision causing the person to have a lessened field of view and problems in depth perception.

Seniors are less likely to be depressed if they sip four or more cups of green tea daily. In a study involving both men and women, all of whom were over 70, Japanese researchers found that those subjects who drank more than four cups of green tea were 44 percent less likely to report symptoms of depression than those who drank less than four cups daily. The effects of green tea held true even after the researchers factored in gender, social and economic status, diet, history of medical problems and antidepressant use. No such association with depression was found for black or oolong tea or coffee. More studies are needed to confirm that drinking green tea really does have an anti-depressant effect, but the investigators noted that the amino acid theanine found in green tea may play a role in the benefits they saw. The study was published in the December 2009 issue of the American Journal of Clinical Nutrition.
Sound far-fetched? The British researchers who found the link between giving kids daily sweets - candy and chocolate - and violent behavior when the youngsters grow up suggest that the "instant gratification" of treats on demand may teach kids that impulsiveness pays off, and perhaps foster aggression later in life. This was a large study with more than 17,000 participants; data on their health, education, social and economic circumstances and consumption of sweets was collected when the kids were five and 10 years old and later when they were 26, 30, 34 and 42.
The study showed that of the participants who had eaten sweets daily as children 69 percent had violent tendencies by the age of 34, while these behaviors were seen in only 42 percent of those who didn't get daily sweets. While the researchers said that their findings need further attention, they suggested that improving youngsters’ diet may enhance their health and make them less prone to aggression. The study was published in the October 2009 issue of the British Journal of Psychiatry.
Rainy season is one season that is loved by all. But when it approaches, it shows its effects on skin and hair. Skin tends to lose its moisture and luster while the hair tends to become frizzy. The combination of oil and sweat makes the condition even worse. In rainy season, it is essential to have clean scalp as humidity and oil may cause infections.
Investigators there gave lab rats green tea to drink and then tested their eyes to see if the tea's catechins had any beneficial effect. They found that the antioxidants reduced oxidative stress in the animals' eyes for up to 20 hours. Based on these findings, the Chinese researchers suggested that catechins are absorbed by the lens, retina and other parts of the eyes, although they don't yet know how the antioxidants get to the eyes from the gastrointestinal system.
Based on their findings, the investigators said that catechins might protect the eyes from oxidative stress and, in humans, might help prevent such common eye diseases as glaucoma. The researchers noted that other antioxidants capable of protecting the eyes include vitamin C, vitamin E, lutein and zeanxanthin. The green tea study was published in the February 10, 2009, issue of the Journal of Agricultural and Food Chemistry.
