Common surgical techniques include scleral buckle, pneumatic retinopexy, and vitrectomy. The choice of surgery depends on the type and severity of retinal detachment.
Laser surgery can be effective in treating certain types of retinal detachment. Its success depends on various factors such as the size and location of the detachment. In some cases, other surgical interventions may be necessary.
"Retinal detachment" is the usual medical term. The condition is most commonly due to a tear in the retina especially in people who are short sighted (myopic). This is a technically a rhegmatogenous retinal detachment. The rip allows fluid from the vitreous cavity to pass beneath the retina so the retina progressively separates from the retinal pigment epithelium beneath. Ultimately the entire retina can detach called a total detachment. This is sometimes also called a "funnel detachment" because the retina remains attached to the optic nerve at the back of the eye. There are other types such as "tractional retinal detachment" in patients with severe diabetic eye disease or "exudative detachments" due to inflammatory conditions.
DefinitionRetinal detachment is a separation of the light-sensitive membrane in the back of the eye (the retina) from its supporting layers.Causes, incidence, and risk factorsThe retina is a transparent tissue in the back of the eye. It helps you see the images that are focused on it by the cornea and the lens. Retinal detachments are often associated with a tear or hole in the retina through which eye fluids may leak. This causes separation of the retina from the underlying tissues.Retinal detachment often occurs on its own without an underlying cause. However, it may also be caused by trauma, diabetes, an inflammatory disorder. It is most often caused by a related condition called posterior vitreous detachment.During a retinal detachment, bleeding from small retinal blood vessels may cloud the interior of the eye, which is normally filled with vitreous fluid. Central vision becomes severely affected if the macula, the part of the retina responsible for fine vision, becomes detached.The risk factors are previous eye surgery, nearsightedness, a family history of retinal detachment, uncontrolled diabetes, and trauma.SymptomsBright flashes of light, especially in peripheral visionBlurred visionFloaters in the eyeShadow or blindness in a part of the visual field of one eyeSigns and testsTests will be done to check the retina and pupil response and your ability to see colors properly. These may include:Electroretinogram (a record of the electrical currents in the retina produced by visual stimuli)Fluorescein angiographyIntraocular pressure determinationOphthalmoscopyRefraction testRetinal photographyTest to determine your ability to see colors properly (color defectiveness)Visual acuitySlit-lamp examinationUltrasound of the eyeTreatmentMost patients with a retinal detachment will need surgery, either immediately or after a short period of time. (However, surgery may not be needed if you do not have symptoms or have had the detachment for a while.)Types of surgery include:Cryopexy (intense cold applied to the area with an ice probe) to help a scar form, which holds the retina to the underlying layerLaser surgeryto seal the tears or holes in the retinaPneumatic retinopexy (placing a gas bubble in the eye) to help the retina float back into placeLaser surgey is performed after pneumatic retinopexy to permanently fix it in place. This is often done in a doctor's office.More extensive detachments may require surgery in an operating room. Such procedures include:Scleral buckle to indent the wall of the eyeVitrectomy to remove gel or scar tissue pulling on the retinaSee also: Retinal detachment repairExpectations (prognosis)What happens will depend on the location and extent of the detachment and early treatment. If the macula has not detached, the results of treatment can be excellent. Most retinal detachments can be repaired, but not all of them.ComplicationsThe unsuccessful reattachment of the retina results in loss of vision.Calling your health care providerA retinal detachment is an urgent problem that requires medical attention within 24 hours of the first symptoms.PreventionUse protective eye wear to prevent eye trauma. Control your blood sugar carefully if you have diabetes. See your eye care specialist at least yearly, especially if you have risk factors for retinal detachment.ReferencesCostarides AP.

The two major RVO types are central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO).
Yes there are actually a few risks to consider when deciding whether or not to have surgery to correct your astigmatism. Your vision could actually get worse if not done correctly, it can become infected or you could lose your sight completely.
its not lasers are Diffractions it is refractions
There are many different types of bariatric surgies. In fact new forms of surgery are being found everyday. You can go tot he website www.lapband.obeseinfo.com/Bariatric-Surgery-Chart.htm to find a comparision of all these surgeries.
There are many different types of plastic surgery. Some of which can be traced back to the Ancient Romans. As we know it today, the surgery was discovered in 1891.
Bariatric surgery consists of different types of surgeries used to help individuals suffering from obesity to lose weight. Some of these types of surgeries include the Lap-Band System and Gastric Bypass surgery. The best bariatric surgery may be debatable amongst those who have undergone bariatric surgery. While each of the different types of bariatric surgery has its own list of pros and cons, all of these surgeries are performed with the intent to benefit the patient by helping them to lose weight and maintain a healthier life.
Laser surgery is one form of hair removal surgery. They also have electrolysis and plastic surgery. I have tried laser and it is wonderful. It's painful but not worse than surgery or electrolysis.
Gastric banding and gastric bypass surgery are the two main types of baruatruc surgery. Gastric banding is a process to lessen your food intake by placing a band around your stomach. Gastric bypass surgery lessens your food intake by removing a portion of your stomach.
There are several different types of laser surgery for treating different types of glaucoma. Some types of glaucoma do not require laser surgery and can be treated with medication. Inquiring with the doctor over the case should establish this. If the glaucoma has become severe laser surgery is often the last option before actual invasive surgery. It is rare that there is a loss of eye site due to this type of surgery. It should be noted that this surgery can not return eyesight that has already been lost nor can it cure glaucoma. As such, consistent careful monitoring after the surgery is necessary. This will decrease the chances of severe side effects as well.
