Surgical interventions for traumatic optic neuropathy (TON) lack evidence from randomized controlled trials. Current data suggests spontaneous visual recovery is common, and surgery may carry risks without proven benefit.

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Trauma Care

Background:

  • Traumatic optic neuropathy (TON) causes severe vision loss after head trauma.
  • Secondary retinal ganglion cell loss is attributed to optic nerve swelling or bone compression.
  • Optic nerve decompression via steroids or surgery is proposed to improve outcomes.

Purpose of the Study:

  • To review the efficacy and safety of surgical interventions for managing traumatic optic neuropathy (TON).

Main Methods:

  • Searched multiple databases (CENTRAL, MEDLINE, EMBASE, etc.) and references for relevant trials.
  • Included only randomized controlled trials comparing surgical intervention (with or without steroids) to steroids alone or no treatment.
  • Two authors independently screened studies; no trials met the inclusion criteria.

Main Results:

  • No randomized controlled trials were identified that met the inclusion criteria for this review.
  • The available evidence is limited to small, retrospective case series, making comparisons difficult.

Conclusions:

  • There is no evidence that surgical decompression of the optic nerve offers additional benefit in TON, despite spontaneous visual recovery rates.
  • Surgery for TON carries risks, including cerebrospinal fluid leaks and meningitis.
  • The decision for surgical intervention in TON remains controversial, necessitating individual case assessment and highlighting the need for high-quality randomized controlled trials.
