Observation
Mild, stable symptoms can be followed with repeat vision checks and OCT imaging.
Macular conditions
Macular pucker (epiretinal membrane)
An epiretinal membrane is a fine layer of tissue on the macula that can wrinkle the retina and distort central vision.
Understanding the concern
A clear diagnosis comes before a treatment plan
A macular pucker, also called an epiretinal membrane, forms on the surface of the macula. Mild membranes can be found incidentally and may not need treatment. Others cause increasing distortion, blur or difficulty using the two eyes together.
OCT imaging shows the membrane and its effect on retinal structure. The decision to observe or operate is based on symptoms and function rather than the scan appearance alone.
What patients notice
Symptoms that may occur
These features can overlap with other eye conditions. Examination is needed to establish the cause.
- Straight lines appearing wavy
- Blurred or distorted central vision
- Objects appearing a different size between the eyes
- Difficulty reading fine print
- Double or mismatched vision when both eyes are open
Specialist assessment
What the consultation may involve
The examination distinguishes an epiretinal membrane from macular hole, swelling, AMD and other causes of central distortion.
01
OCT scan
OCT maps the membrane, traction and retinal thickness and provides a baseline for monitoring.
02
Vision and distortion testing
Visual acuity and patient-reported distortion help establish how much the membrane affects daily tasks.
03
Dilated retinal examination
The peripheral retina, lens and other macular structures are reviewed before any treatment decision.
Treatment planning
Observation or membrane surgery
Not every membrane needs treatment. Surgery is considered when symptoms are significant enough to justify the risks and recovery.
Vitrectomy and membrane peel
The vitreous is removed and the membrane is carefully peeled from the macular surface. Visual improvement can be gradual and may be incomplete.
Cataract planning
Vitrectomy can influence cataract progression. Lens status and any cataract symptoms are considered as part of the surgical discussion.
From first assessment to follow-up
- 01Document distortion and its effect on daily life
- 02Confirm the membrane and retinal structure with OCT
- 03Compare observation with the likely benefits and risks of surgery
- 04Proceed with membrane surgery only when the balance is appropriate
- 05Review retinal anatomy and visual adaptation over time

Deciding when a macular pucker needs treatment
Prof. Amer Awan's vitreoretinal work includes epiretinal membrane assessment and macular surgery. The decision to monitor or operate depends on distortion, visual function, OCT findings and the likely benefit for the individual eye.

Questions patients ask
About Macular pucker
Is macular pucker an emergency?
It usually develops gradually and is not typically an emergency. Sudden loss of vision, flashes, many new floaters or a curtain still require urgent assessment for other retinal problems.
Can drops or glasses remove the membrane?
No. Glasses may optimise focus, but the membrane itself is only removed surgically. Mild cases often do not need removal.
Will distortion disappear completely after surgery?
No complete outcome can be promised. Improvement is often gradual and depends on how long the retina has been distorted and its underlying health.
