Summary

Optic nerve sheath decompression (ONSD) may improve vision for patients with progressive central retinal vein occlusions (CRVO). This surgical intervention showed positive outcomes, stabilizing visual loss in a small patient cohort.

Area of Science:

  • Ophthalmology
  • Neurosurgery

Background:

  • Central retinal vein occlusion (CRVO) can lead to progressive vision loss.
  • Optic nerve swelling is a recognized complication in some CRVO cases.
  • Limited treatment options exist for progressive CRVO with optic nerve involvement.

Purpose of the Study:

  • To evaluate the efficacy of optic nerve sheath decompression (ONSD) in patients experiencing progressive central retinal vein occlusions (CRVO).
  • To assess visual acuity changes and complication rates following ONSD for advanced CRVO.

Main Methods:

  • Retrospective analysis of 8 eyes from 8 patients with progressive CRVO and optic nerve swelling.
  • Optic nerve sheath decompression (ONSD) performed via a nasal approach under retrobulbar anesthesia.
  • Mean follow-up duration of 12 months.

Main Results:

  • Visual acuity improved from a mean of 20/160 preoperatively to 20/70 postoperatively.
  • Six out of eight patients experienced improved vision; two showed worsening.
  • Favorable outcomes were observed in non-ischemic CRVO, patients under 65, and those treated within 3 months.

Conclusions:

  • Optic nerve sheath decompression (ONSD) offers a potential therapeutic option for vision improvement or stabilization in progressive CRVO.
  • The procedure demonstrated a favorable safety profile with no reported complications.
  • Early intervention and specific patient characteristics may influence treatment success.
