What is Detached Retina?<\/h2>\n

Retinal detachment is a condition when the retina or tissue layer of the eye lugs away from the underlying tissue that which nourished and provides it with oxygen.\u00a0 It is an emergency situation wherein a delay in treatment can lead to oxygen deprivation in the cells of retina subsequently permanent vision damage or blindness.<\/p>\n

Retinal detachment occur without ethnic background predilection affecting both male and female while the incidence is more in adults between the ages of 40 to 70 years with the aging process being implicated.\u00a0 Children and young adults however, can also get affected with detached retina which is due more on the activities engaged that ca accidentally traumatize the eye potential for retinal detachment.<\/p>\n

Retina is a multi layer tissue found at the back of the eye which is sensitive to light and covers about 65 percent of the interior surface of the eye.\u00a0 Retina act as photo receptor of optic of the eyes in which it focuses on the images captured by the front of the eye while the retina transmits the signals to the brain for interpretation as visual images.\u00a0 The chemical and electrical transmission of the retina prompts impulses of the nerves via the optic nerve fibers to send visual images to the visual core of the brain for interpretation.\u00a0 The retina is spherical in shape with a diameter of approximately 22mm and contains millions of cones and rods.\u00a0 Both the rods and the cones produce excitation in pattern and work together with parts of the brain to make representation of images mirrored in the external environment of the eye or the images captured on the front of the eye.<\/p>\n

Detached Retina Symptoms<\/h2>\n

Retinal detachment is an emergency situation that prompt treatment is necessary to evade oxygen deprivation of the cells in the retina.\u00a0 The necessity to prompt treatment is tantamount to prevention of permanent visual damage and blindness.\u00a0 The incidence of detachment of the retina fortunately does not occur abruptly and without warning signs.<\/p>\n

Floaters and flashing of lights or photopsia are the initial manifestation of retinal detachment.\u00a0 The eyes will suddenly see visions of debris, strings, spots and other minute debris that seems to float before the eyes.\u00a0 Floaters seen are the result of small solidification of vitreous gel while flashings are due to vitreous gel hitting the retina when it loosened or pulled the retina.\u00a0 The appearance of floaters and flashings are not associated with detachment resulting from retinal tear.<\/p>\n

A vision of shadow or curtain perceive in a portion of visual field occurs while the retinal detachment is progressing.\u00a0 The shadow or curtain vision initially begins in the peripheral side of vision then progresses gradually towards the central vision.\u00a0 This kind of vision is usually associated with a retinal tear progressing to detachment of the retina and should be a warning sign to seek immediate medical attention.<\/p>\n

Causes<\/h2>\n

The separation of retina from its underlying tissue can be implicated to numerous factors with retinal tear as the common cause in most cases of detached retina.<\/p>\n

Detachment of retina is classified into three basic types according to the mechanism and cause of detachment.<\/p>\n

Rhegmatogenous retinal detachment is the most common type of retinal detachment and occurs as a result of hole, tear or dialyses in the neuronal layer.\u00a0 The mechanism of separation of retina is the result of leakage of fluid seeping into the retinal cavity resulting to separation of retinal pigment epithelium.\u00a0 The hole and tear in the can be associated with age advancement and other disorders and condition that causes the retina to thin.\u00a0 Enough force applied on the thinning retina can create hole subsequently a collapse in the vitreous then detachment of the retina.<\/p>\n

Exudative or secondary retinal detachment is the result of fluid accumulation underneath the retina as a result of injury, inflammation and vascular abnormalities.\u00a0 This type of retinal detachment is rare and may also be caused by a tumor growth in the choroid of the retina.<\/p>\n

Tractional retinal detachment occurs when the retinal sensory is pulled from the retinal pigment epithelium as a result of fibrous tissue development due to injury and inflammation.\u00a0 Proliferative diabetic retinopathy is the common cause of this type of retinal detachment including penetrating trauma.<\/p>\n

Other factors are also being considered to contribute for predisposition of retinal detachment and these include the following:<\/p>\n
