Medical Video: 10 Great Exercises to Improve Your Eyesight
What is your minus glasses score? We recommend that you start to consider undergoing LASIK if your minus is high. The reason is, the higher the minus you are, the higher the risk that the retina can be released from the eyeball. This condition is called the retinal detachment, which can cause sudden blurred vision - maybe even sudden blindness. Retinal detachments include medical emergencies. The risk of retinal detachment is found to be highest in the eye minus 8 and more. How come?
What is retinal detachment?
The retina is a thin layer of cells located on the back of the eyeball that is responsible for capturing light. The received light will stimulate the nerves of the eye to process it into electrical signals that will be sent to the brain so that we can see the image.
Retinal function is more or less the same as the function of the film or sensor on the camera. The camera sensor functions to capture light, then translates it into an image. When the camera sensor is damaged, the resulting image will be disturbed or even have no image at all. Likewise if the retina is damaged. As a result, vision will be blurry and may not even be able to see.
Retinal detachment is the condition of detachment of the retina from the surrounding supporting tissue behind the eyeball. Retinal detachment results in sudden blurred vision. This can also cause other symptoms, such as flashes of light like a camera flash, blinking continuously, a gray curtain that covers some vision,floaters, until sudden blindness.
Retinal absorption is more common in elderly adults. However, children and young adults who have a high minus eye or nearsightedness are very severe, especially at high risk of experiencing this.
Why are the eyes higherminus, risk retinal detachmentincrease?
Nearsightedness occurs because the eyeball is too long or the cornea is curved too steeply, so the light that should fall right on the retina is in front of the retina of the eye.
Well, people who have severe nearsightedness (a minus score of 8 or even more) have a high risk of experiencing retinal detachments.This is caused by increasingextension of the eyeball to the front which forcibly depletes retinal peripherals.
Depletion of the retina layer can cause the retina to tearso that the vitreous (fluid in the center of the eyeball) will seep into the gap between the retina and the layer behind it. This liquid then accumulates and causes the entire retinal layer to detach from the base.
The risk of retinal detachment in severe nearsightedness can be 15-200 times higher than people with normal vision.
Apart from the minus eye height, what are the causes of the retinal detachment?
Some causes that can cause retinal tears include:
- The retina is thinning and becomes brittle due to age
- Eye injury
- Diabetes complications
- Reduced production of vitreous, so the vitreus will shrink. This shrinking of the vitreus will pull the retina from the base, causing tearing.
In addition to eye minus height, there are several other factors that increase a person's risk of experiencing retinal detachment, namely:
- Have had previous retinal detachment.
- Having a family member with retinal detachment.
- Have had eye surgery or severe eye injury.
- Have had other eye diseases or inflammation.
See a doctor immediately if you experience symptoms of retinal detachment or have risk factors, before the condition worsens and endangers your vision.
