Introduction

Background

Acute retinal necrosis (ARN) can lead to uveitis, retinal detachment, and blindness. Acute retinal necrosis was first described in the Japanese literature in 1971 and termed Kirisawa uveitis. During the past 3 decades, acute retinal necrosis syndrome has been a source of fear, frustration, and fascination for many ophthalmologists. Unfortunately, it usually is a visually devastating condition for the patient.

Pathophysiology

Acute retinal necrosis may be a result of dormant herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), or varicella-herpes zoster virus (VZV) viral reactivation in the retina. The exact etiology of this reactivation is still elusive; however, an immunogenetic predisposition to the disease is likely.

Frequency

United States

Acute retinal necrosis accounts for 5.5% of uveitis cases over a 10-year period.1

International

In Switzerland, acute retinal necrosis accounts for 1.7% of uveitic cases.

Mortality/Morbidity

Significant visual loss may occur. Retinal detachment complicates most cases (~75%) and is a major cause of legal blindness in acute retinal necrosis.

Race

No clear racial predilection exists.

Sex

This condition appears to have a predilection for males; however, the extent is not clear.

Age

Acute retinal necrosis is a disease of young healthy individuals aged 20-50 years.

  • A bimodal age distribution possibly exists, peaking at approximately ages 20 and 50 years. This distribution may be related to differences in etiologic agents.
    • When varicella-zoster virus or herpes simplex virus type 1 is involved, the median age is 57 and 47 years, respectively.
    • When herpes simplex virus type 2 is involved, the median age is 20 years.

Clinical

History

Typically, acute retinal necrosis is a disease of immunocompetent individuals. Initially, patients may complain of the following:

  • Red eye
  • Periorbital pain
  • Hazy decreased vision
  • Other areas of previous infections
    • Primary varicella infections
    • Herpes zoster

Physical

  • Episcleritis or scleritis
  • Keratic precipitates
    • Fine
    • Granulomatous
  • Occlusive retinal vasculitis involving arteries and veins
  • One or more focus of retinitis, resulting in necrosis with discrete borders located in the retinal periphery with circumferential spread
  • Vitritis
  • Optic neuropathy
Severe vitritis with occlusive arteriolitis.

Causes

Most cases of acute retinal necrosis have been reported to be caused by the following:2

  • Varicella-zoster virus
  • Herpes simplex type 1
  • Herpes simplex type 23
