Early detection and swift intervention are paramount when it comes to retinal detachment, a potentially blinding condition affecting the delicate tissue at the back of the eye. Experts emphasize that while it may seem rare, the risk increases with age, high myopia (nearsightedness), and a family history of eye problems.
On October 10, 2025, Dr. Peh Khaik Kee and Dr. Selva Raja Vengadasalam, Consultant Ophthalmologists and Vitreoretinal Surgeons at Sunway Medical Centre in Malaysia, shared critical insights into this sight-threatening condition, outlining warning signs, risk factors, and the latest advancements in treatment.
What Happens During Retinal Detachment?
Retinal detachment occurs when the retina – the light-sensitive layer responsible for vision – separates from its normal position. Though typically painless, this separation is dangerous and, if left untreated, can lead to permanent vision loss.
Dr. Peh illustrates the process by comparing the eye to a camera, where the retina functions as the film. As we age, the vitreous jelly, a clear gel filling the eye, naturally shrinks and pulls away. This can create tears in the retina. If fluid then accumulates behind these tears, the retina can detach. “Don’t wait until the shadow reaches the centre of your vision. This can jeopardise recovery of vision,” Dr. Peh cautioned.
Recognizing the Early Warning Signs
Key indicators of a potential retinal detachment include floaters and light flashes. According to Dr. Peh, “Floaters may look like specks, cobwebs, or even ‘mosquito-like’ shapes drifting in your vision.” A sudden increase in these visual disturbances, particularly at the periphery, warrants immediate attention.
Another crucial sign is the appearance of a shadow or curtain obscuring your vision. This suggests the retina is already beginning to detach. “Even if part of the retina is detached, the patient can retain near-normal vision as long as the macula is still on. But once the macula comes off, the chances of restoring full sight drops significantly,” Dr. Peh explained, highlighting the importance of prompt diagnosis.
Who is at Risk?
While not directly linked to lifestyle or diet, retinal detachment is more common than many realize, affecting approximately 7–14 individuals per 100,000 people, with Malaysia mirroring this global trend. Dr. Selva emphasized that structural factors play a primary role.
Those at highest risk include individuals over the age of 40, people with significant myopia, those with a family history of retinal problems, and individuals who have experienced eye injuries or undergone previous eye surgeries. Dr. Selva also noted a slightly higher incidence among men and, based on clinical experience, within the Chinese community, potentially due to the higher prevalence of myopia in that population.
The Importance of Immediate Action
Although floaters and flashes are common occurrences, only 5 to 10% of cases indicate an actual retinal tear. Therefore, a comprehensive, dilated eye exam performed by a retinal specialist is crucial to determine if urgent treatment is necessary.
Dr. Selva recommends follow-up examinations within two to three months of experiencing symptoms. “Initial exams may not catch a tear right away. This is the critical window when the vitreous is most likely to pull on the retina and create a tear,” he stated.
Modern Treatment Options and Recovery
Early detection allows for the sealing of retinal tears with a laser procedure called photocoagulation. However, once the retina detaches, surgery is the only effective treatment. Procedures like vitrectomy and scleral buckling – both minimally invasive microsurgical techniques – are used to reattach the retina and restore vision.
“Modern vitrectomy uses instruments as small as 0.5 mm,” Dr. Selva explained. “It’s similar to keyhole surgery, which means smaller incisions and faster recovery.” In some instances, a gas bubble is introduced into the eye to help reposition the retina. Post-operative recovery may require patients to maintain a face-down position for several hours daily for one to two weeks.
Prognosis and Long-Term Outcomes
According to Dr. Peh, the success rate for retinal reattachment surgery is high, ranging from 80 to 95 to 97%, depending on the timing of intervention. “If the macula is still attached, patients can regain full visual function. If the macula has detached, about 70% of patients can recover enough vision for daily tasks, including driving,” he said.
It’s important to note that cataracts often develop within 6 to 24 months following retinal surgery, but these can be effectively corrected with a standard cataract operation to further enhance vision.
There is currently no preventative pill or supplement for retinal detachment, but early detection remains the most powerful tool.
“Screening is Seeing! The earlier we detect and treat a retinal tear or detachment, the better your chances of preserving clear, functional vision,” cautioned Dr. Peh.
“Retinal detachment surgery is not about enhancing your vision, it’s about saving your sight,” added 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.”
