Progressive outer retinal necrosis (PORN) can mimic optic neuropathy. Steroid treatment may worsen PORN, highlighting the need for thorough retinal exams before treating presumed optic nerve issues.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Retinal Imaging

Background:

  • Progressive outer retinal necrosis (PORN) is a severe necrotizing herpetic retinopathy.
  • PORN typically affects immunocompromised individuals.

Observation:

  • Two cases presented with initial symptoms resembling optic neuropathy.
  • Vision loss occurred after methylprednisolone treatment in both patients.

Findings:

  • Post-treatment fundus examinations revealed findings consistent with PORN.
  • Steroid administration appeared to exacerbate the retinal necrosis.

Implications:

  • Emphasizes careful peripheral retinal examination in suspected optic neuropathies.
  • Suggests caution in using steroids for optic neuropathy without ruling out infectious retinitis.
