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
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
