Acute retinal necrosis: Difference between revisions

Latest revision as of 15:45, 15 February 2021

Background

Definition:
- Well-demarcated retinal necrosis on peripheral retina
- Rapid progression of necrosis
- Circumferential spread
- Occlusive vasculopathy
- Vitreal and aqueous inflammation
On the spectrum of necrotizing herpetic retinopathy, with progressive outer retinal necrosis on the other end of the spectrum

Differential Diagnosis

Most commonly HSV and VZV, though CMV also possible

Clinical Manifestations

Starts as anterior uveitis (painful, red eye with vision loss) that progresses to retinal necrosis
High rates of retinal detachment and blindness

Management

Directed by causative organism
Involvement of Ophthalmology
Typically requires intravenous ± intravitreal acyclovir, stepped down to oral valacyclovir after 7 to 14 days, to complete 3 months
- Sometimes intravitreal ganciclovir or foscarnet is added
May require steroids, usually added after 24 hours of antiviral therapy
May require vitrectomy or laser therapy
