Summary:
A retinal tear is often treatable by specialists in Singapore if detected early.
Treating a tear may reduce your risk of retinal detachment, but it does not fully prevent it.
Even without symptoms, eye checks from around age 40 can help monitor retinal health.
Maintaining Clarity: The Value of Early Retina Support
Mediacorp actor Elvin Ng first noticed a dark circular shadow at the bottom corner of his right eye in the early hours of the morning. It stayed in place even when he moved his eye. By noon, he went for an eye check, and by evening, he was scheduled for retinal detachment surgery after the shadow had spread further across his vision.
How does a condition like retinal detachment develop over such a short span of time? How is it linked to myopia, and what are the early changes in vision that should prompt you to visit a retina specialist in Singapore?

Understanding the Retina and How It Changes Over Time
The retina is a thin layer of tissue at the back of the eye that works in a similar way to film in a camera, capturing light and converting it into signals that the brain processes as images.
For vision to remain clear, the retina needs to sit in the right position, closely lining the inner wall of the eye. You can think of it like wallpaper that’s attached to a wall.
Retinal detachment happens when this layer lifts or pulls away from the surface. When that occurs, the retina is no longer able to function as it should, and the eye cannot process visual information in the same way.
Depending on how much of the retina is affected — and whether the central area responsible for detailed vision is involved — this can lead to changes in how you see, including reduced clarity in the centre of your vision.
Early Signs That Your Retina May Need Support
Retinal changes do not usually cause pain. In her CNA938 Rewind interview, Dr Clarissa Cheng from Lumin Eye Specialists notes these three key signs associated with retinal changes:
- Floaters that appear suddenly – These may look like small specks, threads, or shadows drifting across your vision. Unlike occasional floaters, these tend to appear abruptly and may continue moving even when your eyes are still.
- Flashes of light – Dr Cheng describes this as brief sparks or flickers, often at the edge of your vision. You may see the flashes even in dim or dark environments.
- A shadow or curtain in the field of vision – This may appear as a dark patch or area where vision is reduced, and it does not shift or clear with blinking.
While these signs are commonly linked to retinal tears or detachment, not all retinal conditions present in the same way. Some may develop more gradually and affect how clearly or comfortably you see over time.
Beyond these, you may also experience:
- A general sense that part of your vision is missing or blocked
- Blurred or distorted vision that does not improve with rest
- Straight lines appearing slightly bent or uneven
- A gradual reduction in clarity, particularly if central vision becomes involved
If something in your vision feels different from your usual baseline and does not go away, you should get it checked. You can clarify what you’re experiencing and find out whether it needs monitoring or treatment.

Who Should Be Especially Vigilant About Retina Health?
While retinal conditions can occur in anyone, the level of risk is not the same across the board. If you have myopia (short-sightedness), your retina has likely been under more strain over time due to how the eye has developed.
Myopia is common in Singapore, regarded as the “myopia capital of the world”, with about 80 to 90% of adults affected. It often starts in childhood and progresses over the years.
In myopia, the eyeball grows longer from front to back. As it elongates, the retina has to stretch to cover a larger surface area. Over time, this can make it thinner and more fragile, especially if you have moderate to high myopia.
You may also want to be more mindful if you’re:
- Over 40 years old
- Have a family history of retinal conditions
- Have had previous eye issues
- Have undergone eye surgery, including cataract or retinal procedures
- Have experienced eye trauma or injury
- Have diabetes or other systemic conditions that can affect the retina
While this article focuses on retinal tears and detachment, other conditions — such as age-related macular degeneration or diabetic eye disease — can also affect the retina over time.
Why Early Retina Support Matters
The retina plays a central role in how you see, particularly when it comes to clear, detailed vision. When it remains in place but begins to show early changes, such as thinning or small tears, there may be opportunities to manage these before they affect vision more significantly.
If these changes progress to retinal detachment and are not treated in time, they can lead to lasting or permanent loss of vision in the affected area.
Your vision may be stable by the end of the second month. If you need glasses, your final prescription can be determined during this period.
While minor glare or night halos may persist for some patients, these often improve gradually over time.
How Early Retina Support Works
Early retina support usually starts with a detailed examination of the back of your eye. This allows a retina specialist to check if the retina is still in place and to look for any areas that may be thinner or under strain.
In some cases, a retinal tear may be found. This is a small break in the retina. You may not notice it straight away, but it can allow fluid from inside the eye to seep underneath and gradually lift the retina.
If a tear is detected early, it can often be treated. One common approach is laser treatment, which creates a seal around the tear. This helps the retina stay in place and lowers the chance of it developing into a detachment.
Practical Steps to Support Your Retina
Supporting your retina often comes down to staying aware of changes in your vision and going for regular checks when needed.
A comprehensive eye examination — especially from around age 40, or earlier if you have moderate to high myopia — usually starts with a dilated eye exam, which allows the doctor to examine the retina more closely.
Depending on what’s found, additional tests such as retinal scans or imaging may be done to look at the structure of the retina in detail or to monitor specific areas over time.
Frequently Asked Questions
Can you fully prevent retinal detachment?
No, retinal detachment cannot be completely prevented. However, early detection of retinal tears or weak areas can reduce the risk, as these can often be treated before they progress further.
Does retinal detachment happen suddenly?
It can feel sudden, but it often begins with earlier changes that may go unnoticed. In some cases, symptoms can develop over hours or days, which is why you should take changes in your vision seriously.
What are the first signs of a retinal tear?
The first signs are often sudden floaters, flashes of light, or a shadow in your vision. These may not affect your sight immediately, but they can indicate a change in the retina that should be assessed.
Why would you go to a retinal specialist in Singapore?
Retinal specialists are trained to assess the retina in detail and identify conditions like retinal tears or detachment that may not be visible in a general eye check.
Schedule a Retina Assessment at Lumin Eye
If you notice changes such as new floaters, flashes of light, or a shadow that does not go away, you should see a retina specialist in Singapore.
Even without symptoms, periodic eye examinations from age 40 onwards can help keep track of your retinal health. If no concerns are found, you may not need to return immediately. You’ll be advised on how frequently you should go for eye assessments, based on your individual risk.
