ABLASIO

ABLASIO

  1. DEFINITION This disease is a state of loss of sensory retina from the retinal pigment epithelium (RIDE).
Neural networks that form part of the light-sensitive retina form a thin membrane that attaches tightly to the proponent of the underlying network. If the two layers are separated, then the retina can not function and if not re-united permanent damage can occur.
Detachments can be started in a small area, but if untreated, the entire retina can be detached. In one form of detachment, retinal tear really experienced. This form of detachment usually occurs in people with myopia or patients who have undergone surgery or patients with eye injuries katark.
On the other detachments, the retina is not torn but separate from the underlying tissues. This separation occurs when the movement of fluid in the eyeball pull the retina or if the fluid that collects between the retina and retinal tissue beneath encouraging.
2. CAUSE
 Most of retinal detachments occur due to one or more tears or holes in the retina, known as retinal detachments regmatogen (Rhegmatogenous Retinal Detachment). The retina is a transparent membrane at the back of the eye that processes the image that is focused on the retina by the cornea and lens.
Retinal detachments are often associated with a tear or hole in the retina, so that the fluid inside the eye seeps through a tear or hole and cause the release of the retina from underlying tissues. # This can happen due to: Trauma # Process aging # Diabetes weight # Diseases of inflammation, but retinal detachments often occur spontaneously.
In premature infants, can occur due to retinal detachments due to retinopathy of prematurity.
During the process of retinal detachment, bleeding from small retinal blood vessels can cause cloudiness in the inside of the eye is normally filled with vitreous humor. If the release of the macula, central vision will be impaired visual field.
Risk factor for retinal detachment are: - Rabun close - A family history of retinal detachments - Uncontrolled diabetes - Trauma.
3. SYMPTOMS Symptoms are often complain about the invisibility of objects usually hover, a flash of light, a sharp decline in sight and there is a parabolic light curtain that rises slowly from the start the bottom of the eyeball and eventually close. Retinal detachment is painless, but can cause irregular shapes picture floating or flashing lights, and cause blurred vision.
Loss of visual function initially only occurs in one part of the visual field, but then spread out in line with the development of detachments.
If the detached macula, is imminent visual impairment and vision becomes blurred.

4. DIAGNOSIS Diagnosis based on symptoms and eye examination results.
# Some checks are performed to determine the integrity of the retina: direct and indirect ophthalmoscopy # Sharpness of vision # Test refraction # Response pupillary reflex # Impaired color recognition # Slit lamp examination # Intraocular pressure, / I> # Ultrasound eye # Angiography fluorescence # Elektroretinogram.
5. TREATMENT Laser surgery can be used to cover a hole or tear in the retina that is usually found before the occurrence of detachment.
With kriopeksi (giving ice cold with a needle) will form scar tissue that attach the retina to the underlying tissue. This technique is used in conjunction with the injection of air bubbles and the head is maintained at a certain position to prevent re-accumulation fluid behind the retina.
Re-attachment of the retina through surgery consists of making grooves on the sclera (white part of eye) to reduce the pressure on the retina so that the retina back against.
6. PREVENTION Use protective glasses to prevent trauma to the eye.
People with diabetes should control their blood sugar levels closely.
If you have a lifetime risk for developing retinal detachment, eye check at least once a year.
