Cat's Eye

Retinoblastoma Retinoblastoma is a cancer on the retina of the eye. The retina is the inside layer of the eye that has the nerves needed for sight. This type of cancer can be found in one or both eyes. Multiple cancerous tumors can develop in one or both eyes. Retinoblastoma is a rare cancer and it is more common in children. If a child has retinoblastoma, he or she is often born with it. However, it is rarely diagnosed at birth. It is usually noticed when a photograph is taken of the face and the

each histogram are separate charts that depict the amount of time the eye was deprived in each kitten, shown in months but measured in days. The numbers running across the bottoms of both of the (larger) histograms, refer to the ocular dominance groups, which tells us which groups of cells are driven by the contralateral, or the non-deprived eye (in this case, the left), and which are driven by the ipsilateral, or deprived eye (in this case, the right). There are seven ocular dominance groups, and

and heavy footsteps, it was pretty much confirmed. Here comes Armina. She burst into the bunk room and ran towards me. As she came closer, I could see her stormy eyes swirling with an oncoming tempest. This only promised some form of mischief would soon unfold. You could almost see it brewing in her mind just behind those gunmetal eyes. It was going to be a super-cell. Easy to judge, by the near maniacal way she grinned. That and her lack of time or consideration to shout my name. She still wore

to play games. It's what new, what everyone wants and sometimes needs. So no matter what, you will see people playing video games and you can’t stop it. So why are video games good for you? Video games especially violent ones help vision and hand eye coordination. Crime rates in the U.S have gone down significantly since video games have gotten more and more popular. The U.S government cannot link violent behavior of people to the playing of violent video games. Many kids and adults have

The central theme of Bladerunner is the relationship between humanity and nature. More specifically it has a purpose in showing how science can negatively influence this fragile relationship. Set in Los Angeles of 2019 we see the decadence of western society into an inhumane harsh impersonal, technology-dominated realm. The inhabitants who fight for their daily survival are in desperate want for nature, contact with which is denied to them by the unrestricted scientific progress and the consequent

result of a condition called presbyopia, also referred to as "old eye" (Goldstein, 2014). Old eye describes when the distance of the near point increases as a person ages. According to Goldstein (2014), "The near point for most 20-year-olds is at about 10 cm, but it increases to 14 cm by age 30, 22 cm at 40, and 100 cm at 60" (p. 25). Generally, this change occurs because the lens hardens with age and the ciliary muscles in the eye become weaker, causing great difficulty in vision when looking at

PHYSICS PROJECT TO STUDY THE OPTICAL LENS OF A HUMAN EYE Eyes are organs that detect light, and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals;

Pathophysiology: Dementia Dementia, also known as Alzheimer’s disease (AD), is a progressive, chronic, and degenerative. 60% of dementia occurs in people over the age of 65. Dementia causes loss of judgment, memory, change in personality, and visuospatial perception. Severe cognitive impairment can occur over time, as well as physical deterioration and death. The brain changes in size and weight as a person ages. There is also a narrowing of the gyri, enlargement of the ventricles, and widening

At the time of responding to this question it is perfectly timed, as finally we have some lovely weather after the extended winter caused by a cold and wet spring. So sunshine, blue skies and starry nights along with higher temperatures are finally with us in the south west. Some Brits will have already made plans to seek warmer weather and the almost guaranteed sun with warm breezes that come with booking a holiday in hot spots. Over the years I have had some pretty fabulous holidays overseas and
