Summary

Nasal limited macular translocation (LMT) effectively displaced the fovea in a patient with age-related macular degeneration and subfoveal choroidal neovascularization. This surgical approach improved vision by ablating the neovascularization.

Area of Science:

  • Ophthalmology
  • Retinal Diseases
  • Surgical Innovation

Background:

  • Age-related macular degeneration (AMD) can cause subfoveal choroidal neovascularization (CNV), leading to significant vision loss.
  • Management of large subfoveal CNV, especially when occult, remains challenging.
  • Limited macular translocation (LMT) is a surgical technique aiming to reposition the macula.

Observation:

  • A case report details a 77-year-old male with vision loss due to a large, temporally centered subfoveal CNV from AMD.
  • The patient underwent nasal LMT, involving punctate retinotomy and chorioscleral infolding, with specific postoperative head positioning.
  • Successful LMT achieved a foveal displacement of 1400 micrometers.

Findings:

  • The surgical intervention resulted in effective nasal foveal displacement, moving the macula away from the CNV.

  • Postoperative laser photocoagulation successfully ablated the entire subfoveal CNV.
  • The patient experienced significant visual improvement, with vision recovering to 20/40 six months after the procedure.

    • Implications:

    • Nasal LMT is a feasible surgical option for select patients with subfoveal CNV.
    • This technique may be particularly beneficial when CNV is centered temporally relative to the fovea.
    • Successful LMT can lead to substantial visual recovery in patients with AMD-related CNV.
