Diabetic retinopathy involves an ocular disorder caused by diabetes, which is caused by damage to blood vessels of the retina. This defect often Diabetic retinopathy involves an ocular disorder caused by diabetes, which is caused by damage to blood vessels of the retina. This defect often causes leakage of fluid or blood in the eye, and if the disease progresses important visual disturbances such as blurred vision proliferation occur. The best way to prevent this disorder is to control diabetes (using insulin or other medications), a periodic eye exam (every one to two years), and exercising and maintaining a healthy diet to prevent the occurrence of the diabetes. When the disorder is in an advanced stage it should be treated by applying argon laser of existing lesions in order to prevent loss of vision. ...
Retinitis pigmentosa is considered a serious eye condition caused most common hereditary retinal degeneration. Progressive causes decreased vision du Retinitis pigmentosa is considered a serious eye condition caused most common hereditary retinal degeneration. Progressive causes decreased vision due to the death of photoreceptors, eye retina cells. So it can end up causing blindness. Its first symptoms are lack of capacity to adapt to the dark nocturna- blindness and decreased visual field, causing tunnel vision. As the disease progresses, symptoms worsen, so it is important to know the development of the disease in close relatives to know how it will affect the patient. Although there is currently no specific treatment for this disease, consumption of vitamins, minerals and other ingredients may help slow its evolution. In addition, vision therapy is also advised, conducting exercises monitored by an ophthalmologist to improve the visual conditions of the patient. ...
Retinopathy is the common name of any non-inflammatory disease of the retina, the innermost layer of the eyeball responsible for receiving and sending Retinopathy is the common name of any non-inflammatory disease of the retina, the innermost layer of the eyeball responsible for receiving and sending images of the eye to the brain. That is why the term encompasses a range of conditions, the most common and known diabetic retinopathy, which occurs due to elevated blood glucose levels in these patients. The symptoms are not evident during the early stages of this type of retinopathy, which can lead to vision loss, so it is important that diabetics undergo regular eye examinations. Its main treatment is photocoagulation, laser surgery to repair abnormal blood vessels that have been created in the retina. Finally, in the case of blood that has entered into the vitreous humor, a vitrectomy is used, a type of surgery used only if the bleeding has been very generous. ...
The vitreous humor is located between the inner surface of the retina and the posterior surface of the lens. It is a formed by 99%, water clear, gela The vitreous humor is located between the inner surface of the retina and the posterior surface of the lens. It is a formed by 99%, water clear, gelatinous liquid. The remaining 1% are proteins, hyaluronic acid, collagen, chloride, sodium, glucose and potassium. Its function is to protect the retina making its surface remains uniform, getting a correct view. Sometimes this becomes opaque gelatinous mass making viewing difficult. When this happens it is necessary to resort to surgery of the vitreous, also known as vitrectomy. This involves removing the vitreous damaged, replacing it with a saline solution. It is a resource used only when vision has decreased considerably and prevents follow a normal rhythm of life for the patient. Besides, this procedure can cause some complications, such as infection, intraocular bleeding and retinal detachment. ...
Diabetes is a disease characterized by a significant increase in blood glucose levels (hyperglycemia ), whose symptoms are usually fatigue, emaciation produced in a short time, excessive thirst and urination extreme ( even at night ). This pathology is caused by an alteration of the action of insulin, either because it does not exist or because the patient's pancreas no longer make it. This last case is what causes diabetes mellitus or insulin-dependent (type I diabetes), which appears in childhood. In the case of people with diabetes type I, substitute this lack of insulin treatment to be followed for life, proper diet that allows greater control of blood glucose levels throughout the day and about good habits of physical exercise. In contrast, type II diabetes is a consequence of hypertension, high cholesterol, obesity, among other causes. Requires more control over diet that is done and sometimes treatment with oral antidiabetic (pills ). Besides, during gestation can also see the unbalanced blood glucose levels, which causes the called gestational diabetes. ...
