Summary:
- A retinal tear occurs when the vitreous pulls away from the retina, creating a break that allows fluid to accumulate underneath, potentially leading to detachment.
- Symptoms such as new floaters, flashes of light, or a shadow across your vision warrant a same-day assessment.
- A tear caught before detachment is typically treated with a 15-to-20-minute outpatient laser procedure; a detachment requires surgery with a less predictable outcome.
- If the macula is involved in a detachment, the vision loss can be severe and permanent. Early treatment is the only reliable way to prevent it.
You notice a few new floaters drifting across your vision. Maybe a flash of light at the edge of your eye. It is easy to put it down to tiredness, screen time, or simply getting older.
But in some cases, these are the first signs of a retinal tear, and what happens next depends almost entirely on how quickly you act. This article explains what a retinal tear is, why it matters, and what the consequences of leaving it untreated can be.
What Is A Retinal Tear, And Why Does It Matter?
A Quick Look At Retinal Anatomy
Picture the retina as a sheet of wallpaper stretched across the inside back wall of your eye. It is packed with millions of photoreceptor cells that detect light and relay visual information to the brain via the optic nerve.
Sitting just in front of it is the vitreous, a clear gel-like substance that fills the middle of the eye. In a healthy eye, the vitreous rests gently against the retina without putting any strain on it.
How A Retinal Tear Forms
As you get older, the vitreous gradually shrinks and becomes more liquid. For most people, this process, known as posterior vitreous detachment (PVD), happens without any issues.
However, sometimes the vitreous pulls too hard on the retina as it peels away, and that force creates a small retinal tear in the tissue. Once the tear is there, fluid from inside the eye can sneak underneath the retina, which may lead to serious problems.
Who Is At Higher Risk Of A Retinal Tear?
Some people are more vulnerable than others. You may be at higher risk if you have:
- Short-sightedness (myopia), particularly at high levels
- Had a previous eye injury
- Had cataract surgery
- A family history of retinal tears or detachment
- Turned 50 or older
People with very high myopia carry a particularly elevated risk because their eyeballs are longer than average, placing greater mechanical strain on the retina.
Concerned about your risk? If you have high myopia, a family history of retinal conditions, or have had cataract surgery, book a retinal screening at Asia Retina to get a clear picture of what’s happening.
What Are The Symptoms Of A Retinal Tear?
Floaters, Flashes, and Shadows
Watch for these warning signs:
- New floaters: spots, threads or squiggly lines drifting across your vision
- Sudden flashes of light, particularly at the periphery
- A dark shadow or curtain creeping in at the edge of your visual field
Seek a same-day assessment if any of these appear suddenly or in combination. These happen because the vitreous is tugging on the retina, and in some cases, because blood or debris has entered the vitreous after the tear.
Why Symptoms Are Easy To Dismiss
Floaters and the occasional flash of light are common in middle age and usually mean nothing. That familiarity makes it tempting to ignore them.
But when these symptoms appear suddenly, multiply quickly, or come with a shadow in your vision, you need to get it checked that day.
Noticing new floaters or flashes? Do not wait to see if they settle. Book a same-day assessment at Asia Retina.
Retinal Tear vs Retinal Detachment: What Is The Difference?
| Retinal Tear | Retinal Detachment | |
| What it is | A break in the retinal tissue | The retina lifts away from its underlying tissue |
| Cause | Vitreous pulling on the retina | Fluid entering through a tear |
| Symptoms | New floaters, flashes of light | Shadow or curtain across vision, floaters, flashes |
| Treatment | Outpatient laser procedure | Surgery required |
| Recovery | Same day | Longer, variable |
| Visual outcome | Generally good if caught early | Variable; worse if the macula is involved |
Why The Distinction Matters For Your Treatment
What Happens If A Retinal Tear Goes Untreated?
The Progression From Tear To Detachment
Fluid continues to pass through the untreated tear, gradually lifting the retina away from the tissue beneath it. The result is a retinal detachment. Some tears take weeks to reach that point. Others get there within days.
Can An Untreated Retinal Tear Cause Permanent Vision Loss?
Yes. Once the retina detaches, the photoreceptor cells begin losing their blood supply and can sustain damage that does not reverse, even after successful surgery.
If the macula (the central part of the retina responsible for sharp, detailed vision) is involved, the impact on your sight can be severe and permanent.
Patients treated before the macula detaches tend to have considerably better visual outcomes than those treated after.
How Quickly Can Things Worsen?
How Is A Retinal Tear Treated In Singapore?
If a retinal tear is caught before it becomes a detachment, a retinal surgeon in Singapore can typically treat it quickly in an outpatient setting.
| Treatment | What it involves | When it is used |
| Laser retinopexy | Laser burns seal the tear with scar tissue | Retinal tear, before detachment |
| Cryopexy | Freezing treatment applied to the outer eye wall | Alternative or addition to laser, depending on tear location |
| Scleral buckle | Band placed around the eye to push the wall inward | Retinal detachment requiring surgery |
| Vitrectomy | Vitreous gel removed and retina surgically reattached | Retinal detachment requiring surgery |
Laser Treatment For Retinal Tears (Laser Retinopexy)
The most common laser treatment for a retinal tear is laser retinopexy, where a retinal specialist uses a focused laser to create tiny burns around the tear.
Those burns form scar tissue that welds the retina back to the underlying layer, stopping fluid from getting through. The procedure is done in a clinic under local anaesthetic eye drops, typically takes around 15 to 20 minutes, with no overnight stay required.
If a retinal detachment has already started, retinal surgery in Singapore may be needed. Your retinal specialist may recommend a scleral buckle or vitrectomy (a procedure to remove the vitreous gel and reattach the retina).
What Does Retinal Tear Treatment Cost In Singapore?
Retinal tear treatment costs in Singapore vary depending on the clinic, the complexity of your case, and whether Medisave or insurance coverage applies.
In general, treatment costs range from S$500 to S$4,000. More complex cases requiring additional procedures can exceed S$4,000.

Why A GP Referral May Not Be Fast Enough
A general practitioner (GP) can refer you for further assessment, but retinal tears require specialist equipment and expertise to be diagnosed accurately.
Waiting several days for a referral appointment when symptoms are active is a risk that is worth avoiding. If your symptoms are sudden and significant, going directly to a retinal specialist in Singapore is often the safer route.
What A Retinal Specialist Can Assess That A GP Cannot
A retinal specialist uses equipment such as an indirect ophthalmoscope and slit-lamp with a wide-field lens to examine the peripheral retina in detail. This level of examination is not available in a standard GP setting.
Only a full dilated fundus examination (a procedure where eye drops widen the pupil so the retina can be inspected thoroughly) can reliably identify a retinal tear and assess its severity.
How Quickly Should You Seek Treatment?
If you develop a sudden increase in floaters, new flashes of light, or any shadow in your vision, seek assessment within 24 hours. Do not wait for symptoms to worsen or resolve on their own. The window between a treatable tear and a surgical detachment can be very short.
