Retinal Detachment Surgery & Emergency Retinal Care
A Retinal Detachment occurs when the retina, the light-sensitive layer of the eye, lifts and separates from the underlying tissue that nourishes it. This contact is critical for normal function, and the part that becomes affected starts causing blurred vision.
Most retinal detachments begin with a retinal break, often shaped like a horseshoe tear. Retinal breaks most frequently arise following a Posterior Vitreous Detachment, a normal age-related process where the vitreous gel that fills the eye moves away from the retina. In some cases, the traction during this process can create a break, allowing fluid to pass underneath the retina and cause detachment.
Retinal detachments most commonly progress and enlarge quickly and without treatment can lead to visual loss, particularly when the central part of the retina, the macula becomes involved.
Less common causes of retinal detachment include small holes that most frequently occur in short-sighted people, and retinal dialysis, a type of retinal break where the retina separates from its most forward edge inside the eye, often as a result of a blunt trauma.
Symptoms of retinal detachment vary, but you should seek urgent attention if you notice:
– Sudden new floaters or a shower of black spots
– Flashes of light
– A shadow, curtain or veil across your vision
– Blurred or distorted central vision
Retinal detachment is a time-critical condition. Early diagnosis and prompt treatment offer the best chance of protecting or restoring vision.
Retinal detachment is a serious condition that usually requires prompt treatment to preserve vision. The choice of treatment depends on several factors including the type and size of the detachment, the location of the retinal tears, the condition of the vitreous gel, and individual patient circumstances.
Laser or Cryotherapy
When a retinal tear or break is detected before the detachment develops, it can often be sealed using laser retinopexy or freezing treatment (cryopexy). These treatments create a strong scar adhesion around the tear, preventing fluid from passing underneath the retina, and reducing the risk of progression to retinal detachment.
However, once the retina has detached, surgery is required
Vitrectomy with Gas or Silicon Oil Tamponade
Vitrectomy is the most commonly performed operation for retinal detachment. During the keyhole surgery, the vitreous gel is removed to release traction on the retina. The retina is then carefully repositioned, and laser treatment is applied to secure the tear. A gas bubble, or in more complex cases silicon oil, is placed inside the eye to support the retina while it heals.
This approach is highly effective and allows precise treatment of both simple and complex retinal detachments.
Scleral Buckle Surgery
A scleral buckle involves placing a soft silicon band around the outside of the eye. This gently supports the retinal tear from the outside, allowing it to seal naturally. Buckle surgery is adequate for almost every detachment, and particularly effective in selected cases, such as younger patients, retinal dialysis, or detachments without significant vitreous traction (without posterior vitreous detachment). It may be used alone or combined with vitrectomy when appropriate.
Pneumatic Retinopexy
In carefully selected cases, a gas bubble can be injected into the eye without full surgery. The bubble rises to press against the retinal tear while laser or cryotherapy is applied. This technique is less invasive, but only suitable for specific types of retinal detachment, and requires strict positioning afterward.
A retinal detachment can feel alarming, but effective treatment is available and outcomes are often very good when managed promptly.
Surgery can become complex, but modern techniques offer excellent success rate.
Your surgeon will guide you through the most appropriate option for your eye, explain the expected recovery, and support you throughout your treatment.
Your questions answered
Is retinal detachment an emergency?
Yes. A retinal detachment usually requires urgent assessment and treatment. Prompt care significantly improves the chance of preserving vision, particularly if the central part (macula) is still attached.
Can cataract surgery increase the risk of retinal detachment?
Cataract surgery slightly increases the risk of retinal detachment. However, the overall risk remains low.
Will I need to position my head after surgery?
Posturing after surgery is normally required to position the gas bubble in contact with the breaks.
Your surgeon will provide clear guidance tailored to your procedure.
Will I be able to fly after surgery?
If a gas bubble is used during surgery, flying and high-altitude travel must be avoided until the bubble has fully dissolved.
Your surgeon will advise when it is safe to travel again.
How long does vision take to recover after retinal detachment surgery?
Structural repair is often achieved quickly, but visual improvement can continue over weeks. The final visual function depends on several factors including the duration of the detachment.
Can retinal detachment happen again?
While surgery is highly effective, there is a small risk of recurrence. New detachment long after the initial repair is also possible, but very low risk.
Early assessment of new symptoms is important.
