Although AMD can be a significant visual disability, it is almost never completely blinding. There are two forms: dry form, and wet form. The dry form of macular degeneration is characterized by yellow deposits, called drusen in the macula. A few drusen may not cause change in vision, as they grow and increase in size and number it may lead to diming or distortion of vision most noticeable when reading. In more advanced stages, there is also a thinning of the light-sensitive layer of cells in the macula leading to atrophy, or tissue death.
Etiology Retinal detachment can occur as a result of: * Shrinkage or contraction of the vitreous-the gel-like material that fills the inside of your eye. This can create tugging on the retina and a retinal tear, leading to a retinal detachment. * Injury * Advanced diabetes * An inflammatory eye disorder How retinal detachment occurs Retinal detachment can occur when the gel-like material (vitreous) leaks through a retinal hole or tear and collects underneath the retina. Reasons for holes or tears include: * Aging or retinal disorders can cause the retina to thin. Retinal detachment due to a tear in the retina typically develops when there is a sudden collapse of the vitreous, causing tugging on the retina with enough force to create a tear.
There can also be changes in colour perception, a yellowing of vision, and a tendency towards long sightedness as the lens becomes thicker, stiffer, denser and moves forward in the eye. 1 Figure 1 shows the main causes of visual impairment in the UK. These are refractive error (31.6%), AMD (36.2%), cataract (24.5%), glaucoma (7.9%) and diabetic eye disease (2.3%). Other conditions included vascular occlusions and myopic degeneration. 2 Figure 1.
A pink eye is the most obvious symptom of conjunctivitis, so the term "pink eye" often is used for this common eye problem that can have many different causes. A pink eye, along with itching, burning, stinging, irritation, pain, grittiness, crusting or light sensitivity, are all symptoms that provide clues about the type of conjunctivitis you could have. Contagious forms of pink eye are usually linked to bacterial or viral infections. Non-contagious pink eye can occur when eye irritants such as allergens, dust and smoke are in the environment. Coughing and sneezing can spread contagious pink eye by spraying tiny droplets from infected mucus into the air.
It is an analgesic. 8. Echocardiogram is a test that uses sound waves to create a moving picture of the heart. 9. Erythema (multiforme) is a skin disorder that comes from an allergic reaction or infection.
Second is the color of the laser light being more highly absorbed by the tattoo pigment than the surrounding skin. Thirdly, the time duration (pulse duration) of the laser energy must be very short, so that the tattoo pigment is heated to fragmentation temperature before its heat can dissipate to the surrounding skin. Otherwise, heating of the surrounding tissue can cause burns or scar. Lastly, sufficient energy must be delivered during each laser pulse to heat the pigment to fragmentation. If the energy is too low, pigment will not fragment and no removal will take place.” There are side effects to laser tattoo removal.
* Smokers have 22% risk of cataract extraction, causing blind spot directly in line of sight. * Smoking can cause damage to Macula this is the retina of eye, the macula is used when looking directly at a item or person as well as reading. * Smoking constricts blood vessels killing the Macula. This happens when blood vessels weaken or new abnormal blood vessels grow and cause bleeding. * Once blind it cannot be reversed.
Abstract Inheritance of Marfan syndrome: Age of onset associated with Marfan syndrome, gene locus and mutations, disorders attributed with Marfan syndrome, and the common treatments for those affected with Marfan syndrome. MARFAN SYNDROME 3 Marfan syndrome Marfan syndrome is a familiar heritable disorder that affects the fibrous connective tissue with remarkable pleiotropism and clinical variability. (McKusick, 1991) The cardinal signs of Marfan syndrome are discernible in the eye, causing near sightedness from an increased curve of the retina related to the changes that occur with the connective tissue in the globe of the eye. As a result there is an increased risk for retinal detachment, and early cataract formation. The skeletal and connective tissue system include; bone overgrowth and loose joints this causes the arms and legs to become abnormally long and thin.
According to Jensen (1989, p. ) “the iris of the eye can show acute, sub-acute, chronic, and destructive stages in the body”. The iris can also show inherent weaknesses that can be treated or used to understand existing conditions (Jackson, 1993, p. According to Jenson (1989, p 4) there are 90 areas of the iris that correspond to different areas of the body, including every organ, tissue, gland and system. Once these areas are understood, Iridology is then able to analyse the various marks, colours and signs to ”identify weaknesses or overactivity in the body so that future problems can be avoided (Priesnitz, 2003, p 8). The exact reason why these marking appear in the eye at all is still being understood fully, however Jensen ( 1975, p. 17) summarises it as being directly related to the “rate of vibration or a nerve impulse that is carried to the brain area which registers a picture and transmitting it to the iris of the eye”. While the principles of Iridology have been traced back as far as Barbarians (Duncan, 2007) the
Signs and Symptoms - Signs and symptoms to watch out for Tinea Versicolor include the obvious spots of discoloration of the skin. They start of small in areas of the skin that receive the most heat and humidity (or sweat). The splotches may be white, red or pink but the small discolorations are a sign as well as the major symptom of Tinea Versicolor. The spots can appear anywhere on the body and can be dry and scaly (usually not the case). The spots become more noticeable as the skin tans because the yeast prevents the skin from tanning but does not affect the surrounding skin.
