Retinal detachment may sound uncommon, but it is a real and serious risk, particularly for those over 40, individuals with high myopia (short-sightedness), or anyone with a family history of eye problems. Once it occurs, time becomes your most critical ally.
Dr Peh Khaik Kee and Dr Selva Raja Vengadasalam, consultant ophthalmologists and vitreoretinal surgeons at Sunway Medical Centre, Sunway City (SMC), share their insights on this potentially blinding condition—from early warning signs and risk factors to modern treatment options and the importance of swift medical intervention.
What Is Retinal Detachment?
Retinal detachment occurs when the retina, the delicate, light-sensitive tissue at the back of the eye, separates from its normal position. Though painless, the condition is dangerous. If left untreated, it can result in permanent blindness.
Dr Peh compares the eye to a camera, with the retina acting as the film. A clear gel called vitreous jelly fills the eye, but as we age, it begins to shrink and pull away from the retina. This tugging can cause tears, and if fluid seeps through these tears, it can lift the retina and cause it to detach.
“Don’t wait until the shadow reaches the centre of your vision. This can jeopardise your recovery,” warns Dr Peh.
Early Signs: What to Look Out For
Floaters and flashes of light are key warning signs.
“Floaters may appear as specks, cobwebs, or even ‘mosquito-like’ shapes drifting across your vision,” says Dr Peh
A sudden increase in floaters or flashes, especially at the edge of your vision, should prompt immediate medical attention.
Another red flag is a shadow or curtain creeping across your visual field, a sign that the retina may already be detaching.
“Even if part of the retina has come off, vision may remain near normal as long as the macula is still attached. But once the macula detaches, the chances of full recovery drop significantly,” Dr Peh explains.
Who Is at Risk?
According to Dr Selva, retinal detachment is more common than many realise, occurring in roughly 7–14 cases per 100,000 people, and Malaysia is no exception. It is not caused by lifestyle or diet but by structural factors within the eye.
Those at greatest risk include:
- Individuals over 40 years old
- People with high myopia (short-sightedness)
- Those with a family history of retinal problems
- Individuals who have suffered eye injuries or undergone previous eye surgeries
“Retinal detachment is also slightly more common among men,” notes Dr Selva. “In my clinical experience, I have observed a higher number of cases among the Chinese community, possibly due to the greater prevalence of myopia.”
The Importance of Timely Diagnosis
“Symptoms like floaters and flashes are common, but only around 5–10 percent of these cases involve an actual retinal tear,” says Dr Selva.
That’s why a dilated eye examination by a retinal specialist is crucial to determine if urgent treatment is required.
He recommends follow-up checks two to three months after the onset of symptoms.
“An initial exam may not detect a tear immediately. This period is critical because the vitreous is still pulling on the retina and could create a tear,” he explains.
Treatment Options and Recovery
If a tear is detected early, it can often be sealed using a laser procedure known as photocoagulation. However, once the retina detaches, surgery is the only effective treatment.
Depending on the severity, patients may undergo vitrectomy or scleral buckling, both microsurgical techniques that reattach the retina and restore vision.
“Modern vitrectomy uses instruments as small as 0.5 millimetres,” says Dr Selva. “It’s similar to keyhole surgery, meaning smaller incisions, shorter recovery times, and better outcomes.”
In some cases, a gas bubble is inserted into the eye to help press the retina back into place. During recovery, patients may need to maintain a face-down position for several hours each day over one to two weeks to aid healing.
Prognosis and Visual Outcomes
According to Dr Peh, the success rate for retinal reattachment surgery ranges between 80 and 97 percent, depending on how early it is performed.
“If the macula is still attached, patients can regain full visual function. If it has detached, around 70 percent of patients can still recover enough vision for daily tasks such as reading and driving,” he says.
However, most patients develop cataracts within six to 24 months after retinal surgery. This can be easily corrected through a standard cataract operation, often improving vision even further.
Don’t Wait to Save Your Sight
No pill or supplement can prevent retinal detachment, but early detection can make all the difference.
“Screening is seeing! The earlier we detect and treat a retinal tear or detachment, the better the chances of preserving clear, functional vision,” stresses Dr Peh.
“Retinal detachment surgery isn’t about improving your vision. It’s about saving your sight,” adds Dr Selva. “It’s a time-sensitive condition. If you’re at risk or notice sudden changes in your vision, don’t delay. See a specialist immediately.”
