Epi-retinal Membrane (Macular Pucker)
Overview
Epi-retinal
membrane (ERM) or macular pucker is a
cellophane-like membrane that forms
over the macula.
It is typically a slow-progressing problem that affects the central
vision by causing blur and distortion. As it progresses, the
traction of the membrane on the macula may cause
swelling.
ERM is seen most often
in people over 75 years of age. It usually occurs for unknown
reasons, but may be associated with certain eye problems such as:
diabetic retinopathy,
posterior vitreous detachment,
retinal detachment,
trauma, and many others.
Signs and Symptoms
Detection and Diagnosis
The doctor is able to
detect ERM with ophthalmoscopy
during an examination of the
retina. It has a glistening,
cellophane-like appearance. The affect of ERM on the patient's
central vision is assessed with a
visual acuity test and the Amsler
Grid. If the doctor suspects macular swelling, he may
order fluorescein
angiography.
Treatment
A procedure called a
membrane peel is performed when vision has deteriorated to the point
that it is impairing the patient's lifestyle. Most
vitreo-retinal surgeons recommend waiting for treatment until vision
has decreased to the point that the risk of the procedure justifies
the improvement.
The membrane peel is
performed under a local anesthesia in an operating room. After
making tiny incisions The membrane peel is often done in conjunction
with a procedure called a
vitrectomy.
