Area of Science:

  • Ophthalmology
  • Medical Technology

Background:

  • Vitreous membranes can impair vision.
  • Neodymium: YAG (Nd:YAG) laser vitreolysis is a potential treatment.

Observation:

  • 20 eyes with vitreous membranes underwent Nd:YAG laser vitreolysis (1985-1987).
  • Average power: 27 mJ; Maximum power: 65 mJ.

Findings:

  • 18 eyes (90%) showed relief from vitreous strands.
  • Vision improved in 11 eyes, unchanged in 8, and worsened in 1.
  • Complications included lens opacification (2 eyes), retinal hemorrhage (2 eyes), and retinal hole (1 eye).

Implications:

  • Nd:YAG laser vitreolysis is effective for organized vitreous membranes near the optical axis.
  • Success depends on appropriate contact lenses and patient selection.
  • Further research may optimize outcomes for vitreous membrane treatment.
