etinal Detachment

Retina Specialist in Delhi

If you notice some spots and flashes of light while looking at some distance, you may be experiencing the warning signs of a Detached Retina. As a result, your vision might become blurry, or you might experience poor vision. Also, you might see a shadow or a curtain descending from the top of the eye.

A Detached Retina is a serious and sight-threatening event. It occurs when the retina becomes separated from its underlying supportive tissue. The retina cannot function when these layers are detached. And unless the retina is reattached soon, it may result into permanent loss of vision.

Retinal Detachment could be a result of an eye or face injury, cataract surgery, tumors, or eye diseases. But diabetes may also cause Retinal Detachment. It usually occurs when a tear or hole in the retina allows the liquid vitreous to get under the retina and accumulate. The retina separates from the back wall of the eye. This detachment causes symptoms of a gradually enlarging veil or dark shadow in the peripheral visual field. When the detachment extends into the central part of the retina (macula) the central vision is lost.

Retinal Detachment should be fixed immediately to prevent complete loss of vision. Ideally, the Retinal Detachment should be repaired prior to the involvement of the macula. If the macula becomes detached, the vision is unlikely to be as good as it was prior to the Retinal Detachment even with successful surgical reattachment.

Retinal Management


If you experience any warning signal, report to a retina specialist without much delay. At Sharp Sight Group of eye hospitals, our skilled surgeons can treat the retinal tear by welding the retina around it firmly to the eye wall, generally with laser. This welding secures the tear. So as to prevent retinal tears in future, or to avoid any further damage to the eye, visit our team of retina specialists in Delhi, India.

In case of a full-blown Retinal Detachment, where the eyesight is partly or totally lost, a timely surgery is required for the Retinal Detachment Treatment and to retain eyesight. Sharp Sight Centers, known for Retina Treatment in Delhi has modern and state-of-the-art equipments, which enhances the success rates of the surgery.

Causes, incidence, and risk factors

The retina is the clear tissue in the back of the eye. It helps you see the images that are focused on it by the cornea and the lens.

  • The most common type of Retinal Detachment is often due to a tear or hole in the retina. Eye fluids may leak through this opening. This causes the retina to separate from the underlying tissues, much like a bubble under wallpaper. This is most often caused by a condition called posterior vitreous detachment. However, it may also be caused by trauma and very bad nearsightedness (high minus power). A family history of Retinal Detachment also increases your risk.
  • Another type of Retinal Detachment is called tractional detachment. This is seen in people who have uncontrolled diabetes, previous retinal surgery, or have chronic inflammation.

When the retina becomes detached, bleeding from blood vessels may cloud the inside 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.

Symptoms

Retinal Detachment is generally preceded by the formation of holes or tears in the retina; symptoms of which may include sudden onset of flashes and floaters -multiple black spots or cobweb like floating objects in front of the affected eye.

  • When detachment occurs, appearance of curtain falling in front of the eye, decreased vision or total obscuration of vision may happen.
  • Bright flashes of light, especially in peripheral vision is felt
  • Blurred vision
  • Floaters in the eye
  • Sudden appearance of shadow or blindness in a part of the visual field of one eye is experienced v

Tests and Examinations

You will have your vision tested followed by a comprehensive eye examination including a detailed retinal evaluation. Eye drops are put into both your eyes to make the pupils bigger, which helps the ophthalmologist to examine the back of the eye clearly. The effect of these drops will wear off after a few hours, but your vision will be blurred temporarily preventing you from reading and driving.

Avoid driving yourself to hospital or to the local railway station whenever you come to have your retina examined because the pupil of your eye will always be dilated.

.

If you are diagnosed with a Retinal Detachment, you will be advised to have surgery as soon as possible to reattach the retina. Because a delayed surgery reduces the probability of good recovery of vision.

Tests will be done to check the retina and pupil response and your ability to see colors properly. These may include:

  • Visual acuity
  • Slit-lamp examination
  • Ultrasound of the eye
  • Fluorescein angiography
  • Intraocular pressure measurement
  • Indirect Ophthalmoscopy
  • Refraction test
  • Retinal photography/Fundus Photography
  • Test to determine your ability to see colors properly

Treatment

Most people with a Retinal Detachment will need a surgery. Surgery may be done immediately or within a short period of time.

Surgery may not be needed if you do not have symptoms or have had the detachment for a while and retinal scarring has occurred.

Some types of early Retinal Detachment Surgery can be done in your doctor's office. Especially if a small Retinal hole or Tear is seen.

  • Lasers may be used to seal tears or holes in the retina before a major Retinal Detachment occurs.
  • Laser - the retinal hole can be heat sealed (like spot welding) by directing a laser beam of light through the pupil of the eye. The scar produced thus seals the hole.
  • Cryotherapy – Sometimes a freezing treatment applied by a pen shaped probe to the outside of the eye. This freezes promotes scar tissues as a seal.
  • These above procedures may be a little uncomfortable but not painful, and are usually performed under a local anaesthetic as an outpatient procedure. However, they are only effective for retinal holes or tears, without any detachment. But more severe detachments may require surgery in a hospital operating room. Such procedures are based on the severity of Detachment.
  • If you have a small Retinal Detachmnet, the doctor may place a gas bubble in the eye. This is called pneumatic retinopexy. It helps the retina to float back into place. The hole is later sealed with a laser. In addition to the above treatment a detached retina will need a surgical procedure such as application of an encircling band or sponge to support the detached retina with or without drainage of sub-retinal fluid.
  • In patients with old detachment where retina is fixed and immobile, complicated vitreous surgery is generally required to put the retina back to its normal position.
  • Scleral buckle to gently push the eye wall up against the retina.
  • Vitrectomy to remove gel or scar tissue pulling on the retina, used for the largest tears and detachments.This is a time consuming surgery and takes 2-3 hours. Usually silicone oil or gas is injected inside the eye to stabilise the retina.

Expectations (Prognosis)

How well you do after a Retinal Detachment depends on the location and extent of the detachment and how soon you reach out for the right treatment. If the macula (central part of retina) is not damaged, the outlook with treatment can be excellent.

Most Retinal Detachments can be repaired, but not all of them! You may not get back all of your vision after surgery.

Complications

Retinal Detachment usually if untreated causes loss of vision. Surgery to repair it may help restore some or all of your vision, only if performed in time.
