Vitreomacular Traction (VMT)

Question 1

Describe vitreomacular traction?

Answer 1

• Vitreous abnormally adheres to macula, causing elevation +/- distortion
• Traction on macula caused as vitreous separates from retina – leading to elevation & distortion of fovea
• Usually, asymptomatic
  o May lead to FTMH in a few pxs
• May cause metamorphopsia/blurring – so some pxs may be v symptomatic
• V commonly seen on OCT
• Uncommon for px to require treatment

Question 2

Vitreomacular traction management?

Answer 2

• If asymptomatic:
  o None as does not need treatment
  o Do not refer
• If symptomatic:
  o Vitrectomy & peel
  o Ocriplasmin (Jetrea): £2500 per injection, less effective than vitrectomy, complications are both rare & understood
