Strabismus A camera lens focuses patterns of light onto film which records the image exactly. If the lens is out of focus or partially covered, a b lurry or obscured picture will result. The film is a recording device, it does not interpret and select what it portrays. Images from a camera are objective in a very literal sense. Seeing, however, is not such a seamless process. Our eyes work similarly to a camera in that they have a lens which focuses a real image on our retina, a light sensitive

I performed preliminary tests on geriatric and pediatric patients. Performing these exams gave me joy knowing that I assisted in the perfecting of patients vision. Also, I observed patients who suffer with glaucoma, diplopia, and keratoconus ocular disease. This broadened my view on how such eye conditions can limit a person’s ability in life. To enhance my knowledge, I continued to purse this career and worked as an ophthalmic technician and currently working as an

Although they bear some superficial similarities and differences between a Licensed Practical nurse (LPN) and Registered Nurse (RN) are well-defined. LPNs and RNs have many differences and similarities that many people are unaware of. Registered nursing and LPN are both types of nursing, but often have two different roles. Schooling, job duties, places of work and salary are all different when it comes to RNs and LPNs. The basic life support (BLS) had predicted 22% job growth for LPN between 2010
A cerebrovascular accident is known as a stroke. A Stroke is a major illness that affects many people within minutes. It happen when the blood supply to part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen and nutrients. This is an emergency that can’t wait too long to get treatment. The brain needs a consistent supply of blood, which carries the oxygen and nutrient it needs to function. Every artery in the brain works hard to supplies blood to the brain. A stroke
Kelcy Shackelford Visual Impairment Media Rough Draft Visual Impairment Outline I. Intro- Visual impairment is when a person has sight loss that cannot be fully corrected using glasses or contact lenses. Many people will have some type of visual problem at some point in their lives. For example some may not be able to see objects far away or others may have problems reading small print. A. Centers for Disease Control and Prevention (CDC) believe visual impairment is the functional limitation of
Nasopharynx is located at the top of the pharynx, posterior to the nose and above the soft palate. The nasopharynx is lined by a thin layer of respiratory epithelium and most nasopharyngeal carcinoma arises from these cells, that are large polygonal cells with a syncytial composition. The nasopharynx is a part of the pharynx together with the oropharynx and hypopharynx. The main function of the nasopharynx is respiration as it connects the nose to the rest of the pharynx (Marieb & Hoehn, 2007). This

Multiple Sclerosis (MS) is a debilitating disease that affects approximately 400,000 Americans. It occurs two to three more times in women than in men and is most prevalent in women in their early thirties which makes researcher believe hormones play a significant role in developing MS. Patients can go through periods of relapse and remission with the possibility of the symptoms getting progressively worse with each occurrence.

Chapter 29: Introduction to the lens, cataracts and surgery Introduction The human eye is one of the most complex organisms in the human body and the lens is one of the most impressive structures within it! Despite being slightly over two centimeters in diameter, the human eye has over two million moving parts. Sight is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. The lens is a key component of the eye which, coupled with
Nervous System and Diseases Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS)

walleyes are produced when both eyes do not work together because of weakness of the eye muscles. The images formed on the two retinas are so unlike that they cannot be blended in the brain. Thus, a double image is perceived. The condition is known as diplopia, or double vision. Prismatic lenses are prescribed to correct this defect.Imperfections in the cones of the retina, resulting from heredity or disease, cause defective color vision. This is known as color blindness, or Daltonism. In total color blindness
referred to a neuro-ophthalmologist includes visual system disorders, which include optic neuritis, optic neuropathy, brain tumors or strokes. Other efferent visual system disorders that are commonly found in patients who see a neuro-ophthalmologist are diplopia, ptosis, and nystagmus. Neuro-ophthalmologists initially complete a residency in either neurology or
Botulism is a rare but very serious paralytic illness that is caused by the botulinum toxin that is produced by the bacterium Clostridium botulinum. C. botulinum is a gram positive, anaerobic, spore forming bacterium that is naturally occurring in soil. Botulism dates back to the eighteenth century when the first food borne botulism was documented. During this time many people were doing home fermented sausages and this was thought to be the cause of botulism. This is how the toxin got its name
