Summary
- You should consider treatment for an epiretinal membrane if vision distortion, blurring, or difficulty with daily visual tasks start affecting your quality of life.
- An eye specialist can help monitor retinal changes and determine whether treatment or observation is needed.
Epiretinal Membrane: When Is Treatment Needed?
Driving places continuous demands on vision. You need to detect hazards quickly, judge distance accurately, and adapt to varying light conditions. As you age, changes in eye health can gradually affect these abilities. That’s why eye exams are crucial as you age in Singapore.
Read on to know the risks you’ll be avoiding and how these factors into driver’s license requirements as you age.
What Is an Epiretinal Membrane?
An epiretinal membrane is a thin, transparent layer of fibrous tissue that develops on the surface of the retina, most commonly over the macula—the area responsible for sharp, detailed central vision.
As this membrane forms and gradually contracts, it can create subtle wrinkling or distortion of the underlying retina. This may lead to symptoms such as blurred vision, distorted straight lines (metamorphopsia), or reduced visual clarity, especially when reading or focusing on fine details.
ERM usually develops slowly. You may not notice symptoms at first, especially if the membrane is still thin and stable.
However, as it thickens or tightens, it can gradually distort your central vision. While ERM does not usually cause complete vision loss, it can make detailed visual tasks more difficult.
How ERM Affects Central Vision
ERM mainly affects central vision rather than peripheral vision. Your side vision usually remains normal because the macula is responsible for detailed visual tasks.
You may start noticing:
- Difficulty reading small text
- Trouble seeing fine details on your phone or computer
- Faces appearing slightly blurred or unclear
- Lines appearing slightly curved or distorted
These changes can develop slowly, which is why many people only seek help once symptoms start interfering with daily routines.
Mild Versus Severe ERM Changes
If your ERM is mild, vision changes may be barely noticeable. You may only experience slight blurring or occasional distortion. In these cases, your eye specialist may recommend monitoring your condition with regular eye checks.
If your ERM becomes more severe, the membrane may pull harder on your retina. This can cause more obvious distortion, worsening blurring, and difficulty with visual tasks like driving. At this stage, your specialist may discuss treatment options.
Why Epiretinal Membrane Develops
Cataracts are one of the most common age-related eye conditions affecting older adults and a leading cause of vision impairment worldwide.
Cataract is a significant but often under-recognised risk factor for reduced driving safety as it develops gradually. Many elderly driver may unknowingly adapt to declining vision, unaware that their visual performance no longer meets the demands of safe driving.
Age-Related Vitreous Changes
As you age, the gel-like substance inside your eye, called the vitreous, begins to shrink and pull away from the retina, a natural process known as posterior vitreous detachment. This can sometimes trigger scar tissue growth on the retinal surface.
You may not feel this process happening because it is usually painless, but subtle vision changes can develop gradually over months or years.
ERM After Eye Injury or Retinal Conditions
You may also develop ERM after:
- Eye trauma
- Previous eye surgery
- Retinal tears or retinal detachment treatment
- Diabetic retinopathy
- Retinal vein occlusion
These conditions can trigger healing responses inside your eye, which sometimes lead to scar tissue formation.
Inflammation and Eye Health Factors
As you age, the gel-like substance inside your eye, called the vitreous, begins to shrink and pull away from the retina, a natural process known as posterior vitreous detachment. This can sometimes trigger scar tissue growth on the retinal surface.
You may not feel this process happening because it is usually painless, but subtle vision changes can develop gradually over months or years.
When ERM Treatment is Needed
You should consider treatment for an epiretinal membrane when vision changes start affecting how you live and work. You don’t have to wait until symptoms become severe.
Vision Distortion or Wavy Sight
ERM often causes straight lines to look curved or wavy when looking at text, screens, buildings, or patterned surfaces.
This distortion may make it difficult for you to read books, use your phone, or focus on straight edges. If this persists, an eye examination can help assess retinal changes.
Reduced Clarity for Detailed Vision Tasks
ERM can make central vision less sharp, making it harder to read small text, recognise faces, or perform detailed tasks such as writing or close work.
You may find that you need brighter lighting or more time to focus on fine details. When this happens, you should consult an eye specialist.
Gradual vs Sudden Vision Changes
ERM usually develops slowly. However, sudden vision loss, flashes of light, or a rapid increase in floaters require urgent eye assessment, as these symptoms may suggest other retinal conditions.
OCT Evidence of Retinal Traction
If you’re experiencing worsening symptoms of ERM, your eye specialist may use optical coherence tomography (OCT) scans to examine your retina. These scans help show whether the membrane is pulling on your retina and affecting retinal structure.
If you notice persistent vision distortion, book an eye screening at Angel Eye and Cataract Centre. Our eye specialist will assess your retina to determine whether treatment or monitoring is needed.
How ERM Affects Central Vision
If treatment becomes necessary, your eye specialist may recommend a vitrectomy, which is performed as keyhole surgery.
During this procedure, the surgeon makes very small openings in the eye to remove the vitreous gel and gently peel away the epiretinal membrane (“ERM/ membrane peeling”) from the retina using specialised microscopic instruments. Because the surgery is minimally invasive, healing is usually faster, and you can return home on the same day.
After surgery, your vision should improve gradually over several weeks or months. However, recovery depends on how long the membrane was present and how much retinal distortion occurred before treatment.
When Treatment May Not Be Required
You may not need treatment if your ERM remains stable and symptoms are mild.
Mild and Stable Symptoms
If your vision remains stable over time, your eye specialist may recommend monitoring rather than immediate intervention. Regular eye checks help ensure the condition does not worsen unnoticed.
Minimal Vision Impact
If ERM does not affect your ability to work, drive, or perform daily activities, regular monitoring may be sufficient. Many people live comfortably with mild ERM without needing surgery.
Consult an Eye Specialist in Singapore
Epiretinal membrane is different for everyone. At Angel Eye and Cataract Centre in Singapore, our eye specialist, Dr Allan Fong, will assess your retina carefully to monitor any changes and help determine whether treatment or regular observation is needed.
