Epiretinal Membrane Surgery
Epiretinal membrane (ERM) is a condition characterised by the growth of abnormal tissue across the surface of the macula, the central part of the retina.
The eye lens is like that of a camera, receiving light rays in order to transform it into images.
At the heart of this film-like lens layer is the macula, an area that allows us to see objects in sharp detail. An epiretinal membrane (ERM) is what happens when a thin layer of scar tissue forms across this macular area. Your vision might not be affected as it forms, but if the tissue later contracts, it may pull on the retina and distort your central vision. This can make reading difficult. It may also cause straight lines to appear wavy.
The best way to ‘fix’ epiretinal membranes is with a procedure called a vitrectomy. But not everyone who develops ERM will necessarily opt to have surgery. ERM treatment is often a matter of choice – and that’s something we can help you with when you come to the clinic.

Frequently asked questions
What is an epiretinal membrane and how does it affect vision?
An epiretinal membrane, often referred to as macular pucker, is a semi-translucent layer that forms atop the macula, the central portion of the retina responsible for sharp central vision. Patients may notice a gradual decline in visual acuity, including blurriness and distortion, as if looking through cellophane. Detailed images or reading small print become challenging, and straight lines may appear wavy or bent.
How is an epiretinal membrane diagnosed?
Diagnosing an epiretinal membrane involves a thorough eye examination, where Ophthalmologists at Sapphire Eye Care use high-resolution imaging technology. Optical Coherence Tomography (OCT) is the gold standard, offering cross-sectional views of the retina to confirm the presence and extent of the membrane. Visual acuity tests complement these images to assess the impact on vision, facilitating an accurate and early diagnosis which is crucial for optimal treatment outcomes.
What does epiretinal membrane surgery involve?
Epiretinal membrane surgery, or vitrectomy, is a delicate procedure performed by the skilled surgeons at Sapphire Eye Care. The surgery entails making tiny incisions through which specialised instruments are inserted to remove the vitreous gel. The surgeon then carefully peels away the epiretinal membrane from the retina’s surface. The procedure aims to restore the macula’s natural contour and relieve the traction, thereby improving visual clarity and reducing distortion. It is typically carried out under local anaesthesia. The use of intravenous sedation can be discussed with your surgeon in clinic.
What is the recovery process like after epiretinal membrane surgery?
Post-operative recovery from epiretinal membrane surgery is a critical phase managed closely by the Sapphire Eye Care team. Patients might be advised to maintain a specific head positioning to allow the air bubble, placed to facilitate retinal healing, to exert its effect optimally and is dispersed between four and eight days. Use of anti-inflammatory and antibiotic eye drops is standard to reduce swelling and prevent infection. Vision improvement is gradual and may continue to enhance over several months. A follow-up visit is scheduled to monitor the healing process and ensure the retina remains attached and heals properly.
What are the success rates and potential risks of epiretinal membrane surgery?
The success rates for epiretinal membrane surgery at Sapphire Eye Care are high, with patients experiencing a significant improvement in visual distortions and acuity. However, as with any surgical intervention, there are inherent risks, which may include cataract development, infection, or retinal detachment. Prior to surgery, a detailed discussion of potential risks and benefits is conducted to ensure patients are well-informed. Our surgeons utilise state-of-the-art techniques to minimise risks and optimise surgical outcomes.
