There have been other factors that have been associated with the problem more recently, but the severity of illness and the amount of time spent on oxygen seem to be the largest predicting factors. In other words, the infants that are the sickest and the smallest when they are born are the ones that have the highest risk of ROP, and also the ones that have the highest risk for the most serious stages of the disease. Interestingly enough, babies that are African-American appear to be less likely to experience ROP on a level that is considered severe (www.emedicine.com,2002).
During gestation, retinal vasculature usually begins developing around the 16th week. This vasculature grows in a circumferential pattern and does not become fully mature until the baby has reached full term. When a baby is born too early, the vasculature stops maturing. Many of the blood vessels then constrict and some of them are also obliterated. Naturally, this also slows down or stops the progression of normal development of the blood vessels. When the retina continues to grow it often does not get enough blood supply and retinal hypoxia...
There are, however, surgeries that can be performed on these infants. Ablative therapy that involves cryotherapy or laser surgery is one of the most popular methods for care today. Once this takes place, however, the infant will need follow-up care in order to see whether the disease has actually been stopped, as it is sometimes necessary to perform more surgeries. Follow-up care will also be needed for the life of the infant as it grows older (www.emedicine.com,2002).

("Topic Overview," Glaucoma: Yahoo Health, para on "What are the Symptoms?") Diagnosis Glaucoma is diagnosed by an ophthalmologist through a comprehensive eye exam that includes a visual acuity test, which measures the eyesight at various distances; a visual field test to measure the peripheral vision; tonometry, to measure the pressure inside the eye; dilated eye exam for examining the retina and optic nerve for signs of damage by putting special dilatory
Glaucoma is one of the health conditions that have generated significant attention in the health care sector because it is the second-leading cause of blindness. This disease is a major challenge because it progresses or develops without symptoms until it successfully damages the optic nerve. As a result, approximately 50% of people with this condition remain undiagnosed while nearly one in every ten people aged 80 years or more are
Friedrich Wilhelm Ernst Albrecht von Grafe, or Graefe, was born on May 22, 1828 and died July 20, 1870. Graefe He was considered by many, a Prussian pioneer and founding father of 19th century ophthalmology. (Daroff and Aminoff) Father to Albrecht von Graefe and son to Karl Ferdinand von Graefe, he was born in Finkenheerd, Brandenburg. In Berlin, he studied anatomy, natural sciences, logic, and philosophy, going abroad to study
Already, "lawmakers in at least three states are considering joining the 13 states that have legalized pot for medical purposes. Massachusetts voters last fall decided to decriminalize possession of an ounce or less of pot; there are now a dozen states that have taken such steps." (Crary, 1) And as demonstrated by the Appendix B contained below, there is a clear penetration of legalization in every region of the U.S.,
Marijuana Should Not Be Legalized Physical Health Concerns According to a Harvard University Law School document, it would be "…fallacious to conclude that because the chemicals in marijuana have been found to present fewer dangers…" than cocaine, heroin, alcohol and tobacco, that the recreational use of marijuana "is safe" (Harvard). In fact, even though many states authorize the use of cannabis for medical purposes (for AIDS sufferers and for those experiencing harmful
Societal Interventions in Genetic Diseases: Genetic diseases are among the most common diseases that occur or affect a huge portion of the world's population. The main cause of the diseases is attributed to the mutations in genes that are fundamental for the usual functioning of the organism's cells. Following the mutation of a gene, the encoded protein fails to function properly and certain cellular processes are likely to go skewed resulting
