Overview
Natural History
- Symptoms of Acute retinal necrosis (ARN) develop rapidly upon onset of pathogenic infection.[1]
- Initial signs and symptoms include conjunctivitis, vision loss and photophobia, and eye pain and pressure.
- The natural progression of ARN depends on whether the case is mild or fulminant.
- Mild cases of ARN presents with white-yellow necrotic lesions that do not coalesce or lead to retinal detachment; the disease is self-limited.[2]
- Fulminant cases of ARN will lead to progressive necrosis of retinal tissue, leading to pigmentation scarring, vitreous debris, and retinal detachment
- There is a much greater chance of blindness in the affected eye.
- Without treatment, ARN will usually progress to Bilateral acute retinal necrosis (BARN) within weeks to a few months.[3]
Complications
- Complications resulting from Acute retinal necrosis occur due to retinal tissue damage and subsequent infection from the causative pathogen, including the following:[1][5]
- Retinal detachment
- Neurological conditions, such as encephalitis[6] or meningitis
- Optic neuropathy
- Occlusive retinal vasculopathy
- Proliferative vitreoretinopathy[7]
- Macular pucker[8]
- Vitreous hemorrhage
- Neovascularization[9]
- Phthisis bulbi[9]
Prognosis
- Without treatment, the prognosis for Acute retinal necrosis (ARN) varies:[1]
- Mild ARN: Usually self-limited and will resolve itself without treatment; risk of permanent vision loss is very low.
- Fulminant ARN: Will usually progress to complications such as progressive outer retinal necrosis and has a worse prognosis.
- Retinal detachment will usually occur without treatment, leading to permanent vision loss.
- Spread of infection through the anterior chamber to the brain has particularly poor prognosis if encephalitis or meningitis develops.
- With treatment, the prognosis for ARN is good if the therapy is administered in the early stages and sustained until symptoms resolve.
- Uncommonly, prognosis can worsen if the patient is immunocompromised and experiences a subsequent infection due to vulnerability from prolonged topical corticosteroid use.
