Summary

Radial-interrupted mattress sutures for scleral outfolding show greater macular translocation potential than scleral infolding. Further research is needed for age-related macular degeneration treatment.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Retinal Diseases

Background:

  • Macular translocation aims to reposition the macula to a healthier retinal area.
  • Scleral infolding and outfolding are surgical techniques to achieve macular translocation.
  • Age-related macular degeneration (AMD) with subfoveal choroidal neovascularization is a leading cause of vision loss.

Observation:

  • Comparison of scleral infolding versus outfolding techniques in human cadaver eyes.
  • Radial-interrupted mattress sutures for scleral outfolding were applied in a clinical case of AMD.
  • Measurement of internal anteroposterior retinal contour changes after each technique.

Findings:

  • Scleral infolding resulted in an average retinal contour decrease of 0.36 mm.

  • Scleral outfolding created a significantly larger average decrease of 4.61 mm (P=.0001).
  • Radial-interrupted mattress sutures for outfolding demonstrated greater potential for macular translocation.
  • Implications:

    • Radial-interrupted mattress sutures may offer superior macular translocation compared to circumferential sutures.
    • This technique holds promise for treating subfoveal choroidal neovascularization in AMD.
    • Long-term efficacy and safety require further clinical investigation.
