For examining the normality of human eyes, the medical teams have the procedure of pupil examination. Human eyes consist of many parts and organs. One of the most important parts is the pupil. It works as a gate for light to enter the eyes which then will be directed to the brain for constructing the image we see. Any abnormality can cause in vision degradations. This means the pupils have a very important role in being a human’s most vital organs. Without eyes, the human will not be able to see the surrounding world. In medical terms, there is also a simple procedure in examining the pupils’ normality.
Before you understand about the examination for a pupil in one’s eyes, you have to also know the basic information about pupils. Its size is about 2 to 6 mm and both pupils on both eyes have the same size. But, in this world, there are about 15% of people who have the smaller pupil in one eye. This condition is called as anisocoria. But, there are also some conditions in which people develop different pupil sizes in both eyes. For example is on the people who have blinded in one eye. This will effect on how the pupil works and its basic condition.
For people who are the experts in eye medication, conducting the pupil examination is actually easy. The key is on how the eyes will react to the light. In this case, the exam conductor will see the reaction of someone’s eyes pupils. The pupils will be examined by using the size measurements in the light and dark condition. This is important to understand because examining the pupils will be successful when done in the different light condition to see its reactivity. The examination conducted on different lighting will also be a first step in diagnosing the anisocoria on a patient.
The reaction of light will also give insight on someone’s ability in accommodating the eye vision. In this case, the conductor can bring the light beam from the outer corner of the eye to the pupil. If the pupil reacts, it means that the pupil is still in normal condition. The examination conductor will also check for Relative Afferent Pupil Defect or RAPD. For understanding whether someone’s eyes are normal or not, always take the note that the normal pupils have PERL (Pupils Equal and Reactive to Light) and no RAPD (Relative Afferent Pupil Defect).
These examinations can figure out someone’s normality in the term of eyes’ pupil condition. But there is a note for anyone who is examining the pupils’ normality on someone’s eyes. In this case, the people who suffer blindness and someone who has been under the knife for cataract surgery procedure will have a problem in the pupillary reaction. The people who are in medication for eye problems will also get the effect of pupils’ abnormality. The abnormality will not only affected by that condition, as some very rare conditions may lead to those abnormalities. By understanding this, thus you will know the basic procedure for pupil examination.
Pupil Reaction to Light is narrowed but the pupils will widen when they see the darkness. Cataracts are eye diseases caused by white stains in the lens of the eye. Normal eye lens has oxygen and water so that light can penetrate the eye easily. The eye lens will always form a new cell. There are many factors that cause the lens of the eye to be solid, rough, hard, and opaque. Abnormal eye lenses cannot provide light to the retina and are sent to the optic nerve in the brain. The disease is present in tropical countries. Cataracts can cause permanent blindness. It is supported by many factors such as illness, health level, vitamin deficiency, nutrition, ultraviolet radiation, and age. Cataracts will affect the change in the lens of the eye that looks clear. Patients with cataracts may experience symptoms such as light-sensitive, and blurred vision. The light that the patient sees is a pseudo-circle. This disease will form a white stain in the middle of the lens in a short time. Patients with cataracts cannot receive light into the retina and the retina will produce a blurred image. Usually, this disease affects patients with 50 years old and over. Cataracts can affect infants due to disability and mothers who are infected with rubella virus.
Cataracts Pupil Reaction Light
Cataracts can be detected by performing an eye exam. Usually, the examination requires keratometer, Snellen cards, and slit lamp checks. Cataracts can be treated by surgery. Cataracts can be caused by cigarettes. Cigarettes contain free radicals that cause you to suffer from cataracts. Free radicals are electrons that have no pairs. Cadmium can also cause cataracts. Free radicals can produce malondialdehyde compounds that form crosslink’s between lipids and proteins. This bond causes the cell to become damaged. Cadmium is present in the cigarette and accumulates with the membrane to make your eyes damage. This substance can inhibit the performance of antioxidant enzymes so that the lens can experience obstacles. This substance will form a turbidity causing cataracts in your eyes for perrla eyes.
Cataract Pupil Reaction
Cataracts cannot react to light because the lens of the eye is covered by clouds. Cataracts can be prevented by giving vitamin E and C to make your eyes get clear vision. Vitamin E and C are natural antioxidants that will make your eyes experience oxidative damage. Adults who take these vitamins regularly can reduce cataract disease by about 60%. The results showed that high blood plasma concentrations can reduce the risk of cataract disease. Glutathione enzyme levels may be affected by riboflavin. This enzyme can recycle glutathione so it can make free radicals neutral.
Cataracts can be treated by performing surgical techniques with sophisticated technology. Good surgical results reached 95%. Cataract surgery has a small risk and this is rare. If the surgery is successful, the vision may increase to two lines. The examination uses a Snellen chart with certain calculations. There are some people who can be exposed to high-risk cataracts. You must stay away from the cause of cataracts. You can distinguish cataracts by looking at the color of the person’s eyeball. Cataracts can be treated through the treatment of medical and traditional experts. You can eat carrots to cure cataracts. This disease should not be considered trivial because cataracts can be a severe disease for your eyes. That’s the explanation of cataracts and Pupil Reaction To Light.
