Aneurysms are dilatations of the arteries due to a fault in the vessel wall which triggers an increase in diameter and carries the risk of rupture and Aneurysms are dilatations of the arteries due to a fault in the vessel wall which triggers an increase in diameter and carries the risk of rupture and massive internal bleeding. Most cerebral aneurysms are congenital, but can also be traumatic, tumor cause, arteriosclerosis, by common infectious cause or drug consumption. Depending on the shape of the aneurysm are divided into secular, fusiform, and use as side; They may also be classified by size. All aneurysms may be complicated by rupture of the vessel and cause bleeding in the brain, causing a stroke acidente, which can cause irreversible nerve damage. Aneurysms are asymptomatic, symptoms only when they break, causing intense headaches, nausea, vomiting, stiff neck, seizures or sudden loss of consciousness. For diagnosis, several tests such as angiography or CT are used, and the treatment depends on the size of the aneurysm and associated risk factors. There are several alternatives for both conservative and surgical treatment, which must evaluate a neurosurgeon. ...

The epiterretiniana membrane is an eye disease that involves the development of a fibrous membrane area and high vision sensitivity of the retina, th The epiterretiniana membrane is an eye disease that involves the development of a fibrous membrane area and high vision sensitivity of the retina, the macula. When this membrane shrinks and wrinkles produces a series of malfunctions in the retina with consequent alterations in sight. The most common symptoms are progressive visual loss (blurred vision) and distortion in reading images or text. This eye disease occurs in people over 50 years and appears unknown cause. In cases in which no symptoms are evident removal is not necessary (track through regular checks done alone), but in the most severe vitreoretinal surgery should be assessed. ...
Intravitreal injection is an injection of medication into the eyes. The vitreous humor is the fluid which is formed inside the eye. During the ophtha Intravitreal injection is an injection of medication into the eyes. The vitreous humor is the fluid which is formed inside the eye. During the ophthalmologist intravitreal injected the drug into the vitreous humor, in the back of the eye, near the retina. The drug is recommended to treat certain eye and vision problems. Generally, it is a short appearance of between 15 and 30 minutes. First apply a few drops to dilate the pupils, the eyes and eyelids are cleaned, apply a few drops a device with analgesic and keep your eyes open. Later the medicine with a small needle is injected. The patient feels no pain but may feel a slight pressure. Intravitreal injection is usually done in cases with macular degeneration, diabetic retinopathy or retinal vein occlusion. Although there are no risks after surgery, it is possible that the patient may feel pressure or roughness, but no pain. There may also be a small bleeding, will disappear, or seeing floaters, which will improve with time ...
Acute ischemia is the reduction or elimination of the blood supply in an area or organ. The causes may be varied: outside the glass, compression, tumors, scars, etc; or internal, such as thickening of the vessel wall by chronic inflammation, tumor thrombus ... In any case, the three most important causes of this clinical picture are thromboses, embolisms and trauma. Clinically manifested by a sudden and intense pain that does not respond to usual painkillers. It occurs more frequently in the lower extremities, but can affect any area of the body. Ultimately, the lack of blood nutrition can trigger gangrene of ischemic tissue. ...
The macula is the part of the eye responsible for providing a clear view. As we grow faculties it loses its function, causing macular degeneration, also known as AMD. This is a fairly common ailment after 60 years and can occur at various levels, resulting imperceptible in some cases. Conversely, it can also develop much more virulent causing total and progressive loss of sight. Although there is still no definitive treatment to repair the effects of macular degeneration, it is important to make an early diagnosis to slow its progression. Also, it has been found that consumption of antioxidant vitamins and zinc can contribute to this. ...
We say that someone has a macular hole when the patient suffers a break in the macula, or na very small part of our eye that is located in the center of the retina. The macula is responsible for central vision and provide allows us to capture the details in order to perform such everyday activities like reading. Two types of macular holes that affect the function of a partial or full thickness retina way. On the one hand, there are those that affect the entire retina, called lamellar macular holes and, on the other, those affecting our retina partial way, post-traumatic macular holes. ...
Optic neuritis is inflammation of the optic nerve that can be manifested in its outer form and the inner, which is why sometimes it is difficult to diagnosis. Since this is a disease that affects the nerve responsible for transmitting visual information from the retina to the brain, could cause visual loss and injury to the sheath surrounding nerve fibers of the eye. This is a condition caused, often caused by autoimmune diseases, or respiratory viral infections, and, especially multiple sclerosis. Therefore recovery is closely linked to the improvements regarding the disease that has caused. His recovery can also be achieved through corticosteroids administered orally or intravenously. ...
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. ...
Ultrasound is a diagnostic imaging procedure that allows you to view organs and soft structures within the body. It is made using high-frequency sound waves that are emitted by a transducer that captures the echo of different amplitudes which occurs bounce off the organs. These signals, when processed by a computer, give a series of images of the tissues examined. Today may be two-dimensional, three-dimensional or 4-dimensional images. Ultrasound is a noninvasive technique, in which no radiation used and thus is used to visualize fetuses that are being formed. This procedure can differentiate clearly the shape and size of each structure within the body. In medicine it is used to see the heart, kidneys, liver and blood vessels, among other organs. ...
Vision problems encompass a host of pathologies. The most common are refractive comprising: the nearsightedness or myopia, hyperopia, astigmatism and presbyopia. Its causes may be genetically different, due to aging or other diseases such as macular degeneration caused by diabetes. ...
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. ...
