Retinal detachment?
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.

Are possible retinal detachment it's the weekend what steps should you take until you can see a doctor?
Immediately contact a retinal specialist. Look in the phone book for your area, or call your optometrist or opthamologist or regular doctor. Retinal specialists have "after hours" answering services who will contact them with your name, number and symptoms. The "on call" opthamologist will call you back and set up a time, either within a few hours or the next day, for you to come in for a thorough retina exam. Because the retina peels like wallpaper, it's very diffidcult to reattach it. There is no glue...but, there are at least 3 other possible routes to get it reattached and anchored. if it peels up to and over the macula, or center of the eye, possible loss of central vision will occur once the retina is reattached. So! Time is precious if you want the least amount of vision loss and the least invasive reattachment procedure. Read all you can about retina detachment on the internet. Good luck!
Retinal detachment repair?
DefinitionRetinal detachment repair is eye surgery to place a detached retina back into its normal position.A detached retina means the light-sensitive tissue in the back of the eye has separated from its supporting layers.Alternative NamesScleral buckling; Vitrectomy; Pneumatic retinopexy; Laser retinopexyDescriptionMost detachment repair operations are urgent. A detached retina lacks oxygen, which causes cells in the area to die. This can lead to blindness.If holes in the retina are found before a detachment occurs, an opthalmologist can close the holes using a laser. This is usually done in the doctor's office.If the retina has just started to separate, a procedure called pneumatic retinopexy may be done to repair it. Pneumatic retinopexy (gas bubble placement) is also usually an office procedure. The health care provider injects a bubble of gas into your eye. You will be positioned so the gas floats up against the hole in the retina and pushes it back into place. The surgeon will use a laser to permanently seal the hole.More severe detachments require more advanced surgery. The following procedures are done in a hospital or outpatient surgery center:The scleral buckle method bends the wall of the eye inward so that it meets the hole in the retina. Scleral buckling can be done under local or general anesthesia.The vitrectomy procedure uses very small instruments inside the eye to pull the retina forward. Most vitrectomies are done under local anesthesia.For some complex detachments, both procedures may be done during the same operation.Why the Procedure Is PerformedRetinal detachments do not improve without treatment. Repair is necessary to prevent permanent vision loss.The urgency of the surgery depends on the location of the detachment. If the detachment has not affected the central vision area (the macula), surgery should be done quickly, usually the same day. This is necessary to prevent further detachment of the retina.If the macula detaches, the surgery can still be done, but the vision result will not be as good. If the macula has already detached, there is less urgency. Surgeons can wait a week to 10 days to schedule surgery.RisksRisks for retinal detachment surgery may include:Detachment not completely fixed (may require additional surgeries)Increase in eye pressure (elevated intraocular pressure)BleedingInfectionGeneral anesthesia may be required. The risks for any anesthesia are:Reactions to medicationsProblems breathingAfter the ProcedureThe chances of successful reattachment of the retina depend on the number of holes, their size, and whether there is scar tissue in the area.Most of the time, the retina can be reattached with only one operation, although some people need several surgeries. Less than 10% of detachments cannot be repaired. Failure to repair the retina always leads to poor or no vision in the eye.After surgery, the quality of vision depends on where the detachment occurred:If the central area of vision was not involved, vision will usually be very good.If the central area of vision was involved for less than 1 week, vision will usually be improved, but not 20/20 (normal).If the central area of vision was detached for a long time, vision will return, but it will not be sharp.Outlook (Prognosis)The procedures usually do not require an overnight hospital stay.You will need to limit activities for some time.If the doctor repaired the retina using the gas bubble procedure, you must keep your head face down or turned to one side for several weeks. It is important to maintain this position so the gas bubble pushes the retina in place. Patients with a gas bubble in the eye may not fly.ReferencesYanoff M, Duker JS, Augsburger JJ, et al.

What causes a bright spot in the direct line of vision?
They vary in cause, but sometimes they are caused by dead blood cells clumping in the vitreous fluid around your eye. Sometimes though they can be caused by retinal detachment. But this is not likely, because retinal detachment is very rare.
What is the receptor for equilibrium?
The Macula is the receptor for static equilibrium.

What courses the central retinal artery?
It pierces the optic nerve close to the eyeball, sending branches over the internal surface of the retina, and these terminal branches are the only blood supply to the larger part of it. The central part of the retina where the light rays are focussed after passing through the pupiland the lens is a circular area called the macula. The center of this circular area is the fovea. The fovea and a small area surrounding it are not supplied by the central retinal artery or its branches, but instead by the choroid
When you are blind what part of the eye is injured?
It could be damage to the retina, macula, optic nerve or loss of blood supply. The vertebrate retina is the light sensitive inner layer of the eye. Two of its three types of photoreceptor cells, rods and cones, receive light and transform it into image-forming signals which are transmitted through the optic nerve to the brain. If that is damaged such as retinal detachment then blindness can occur. Structures in the macula are specialized for high acuity vision. Within the macula are the fovea and foveola which contain a high density of cones (photoreceptors with high acuity). Whereas loss of peripheral vision may go unnoticed for some time, damage to the macula will result in loss of central vision, which is usually immediately obvious. The progressive destruction of the macula is a disease known as macular degeneration and can sometimes lead to the creation of a macular hole. Macular holes are rarely caused by trauma, but if a severe blow is delivered it can burst the blood vessels going to the macula, destroying it. The small photoreceptors of the retina (the inner surface at the back of the eye) sense light and transmit impulses to the optic nerve. The optic nerve from each eye carries impulses to the brain, where visual information is interpreted. Damage to an optic nerve or damage to its pathways to the brain results in loss of vision. At a structure in the brain called the optic chiasm, each optic nerve splits, and half of its fibers cross over to the other side. Because of this anatomic arrangement, damage along the optic nerve pathway causes specific patterns of vision loss.
