A fibrocellular proliferative membrane on the macular retinal surface that can cause traction, leading to metamorphopsia and vision loss.

Common Symptoms
Focus on the most useful decision cues first: common symptoms, the patients or situations that usually prompt review, and any signs that need faster assessment.
Common Symptoms
Signs patients often notice before evaluation
Metamorphopsia (straight lines appear wavy)
Gradual vision decline
Blurred vision
Macropsia or micropsia
When to Seek Evaluation
Typical patients and situations that warrant review
Adults over 50
Previous retinal detachment surgery or laser treatment
Post-intraocular inflammation
Progressive worsening of metamorphopsia
Vision decline affecting daily activities
Epiretinal membrane detected on OCT
Treatment Approaches
Observation (mild membrane with good vision)
Vitrectomy with membrane peeling (when membrane affects vision and quality of life)
What usually shapes the treatment plan
Clinical Assessment
These are the main areas doctors usually review first. If you already have relevant test or imaging reports, bring them to speed up the assessment. They are helpful but not required, and the same workup can also be completed in China.
OCT (assess membrane thickness, traction degree, and macular structural changes)
Visual acuity testing
Amsler grid
Fundus photography
Before You Travel
Bring recent OCT reports
Document progression of metamorphopsia
Planning Notes
Pre-Assessment Required
Detailed OCT assessment of membrane characteristics and macular structural changes is needed, combined with visual acuity and symptoms to determine surgical necessity.
Remote Pre-Assessment
OCT images and visual acuity records can be submitted remotely for surgical necessity assessment.
Multidisciplinary Assessment
Medical History Important
