Progressive outer retinal necrosis (PORN) syndrome is a form of chorio-retinitis, an infection in the retina, the back of the eye. The disease is most commonly caused by the Varicella zoster virus and is found almost exclusively in patients with HIV/AIDS (acquired immunodeficiency syndrome) Progressive outer retinal necrosis (PORN) syndrome is a form of chorio-retinitis, an infection in the retina, the back of the eye. The disease is most commonly caused by the Varicella zoster virus and is found almost exclusively in patients with HIV/AIDS (acquired immunodeficiency syndrome). Progressive outer retinal necrosis is the second most common opportunistic retinal infection in North. Progressive Outer Retinal Necrosis Etiology Progressive outer retinal necrosis, or PORN, is a destructive, rapidly progressing necrotizing herpetic retinopathy with features distinct from those of ARN. As with ARN, PORN represents reactivation of a latent VZV or HSV infection

Retinal Necrosis Infectious forms of uveitis associated with retinal vasculitis can be associated with necrosis of retinal layers. This is commonly seen in eyes with toxoplasmosis, [39] viral infections such as varicella zoster [40] or herpes simplex, [41] cytomegalovirus [42] and human T-cell lymphoma virus type 1. [43 Patches of retinitis may become confluent and are often associated with a vasculitis and vascular occlusion. Syphilitic retinitis may resemble acute retinal necrosis or progressive outer retinal necrosis, however unlike these mimics syphilitic necrotizing retinitis is only slowly progressive and shows a robust response to intravenous penicillin The progressive outer retinal necrosis syndrome.

Intravitreal antivirals in the management of patients with acquired immunodeficiency syndrome with progressive outer retinal necrosis People with the condition usually display redness of the eye, white or off-white colored patches that are patches of retinal necrosis. ARN can progress into other conditions such as uveitis, detachment of the retina, and ultimately can lead to blindness. The disease was first characterized in 1971, in Japan

Progressive outer retinal necrosis (Definition/Background Information) Acute Retinal Necrosis (ARN) is a debilitating eye condition involving the retina, which can cause blindness, if left untreated.

Acute retinal necrosis is a relatively newly described entity. It was initially reported in 1971 by Urayama et al in otherwise healthy young Japanese adults.

  1. Progressive outer retinal necrosis consists of a retinitis, often in the posterior pole, that is not usually associated with an inflammatory reaction. However, the two diseases can occur simultaneously, one eye having ARN and the other progressive outer retinal necrosis. 106 Both necessitate intraocular and systemic antiviral treatment
  2. Less common findings are retinitis, progressive outer retinal necrosis or multifocal choroiditis. Diagnosis of herpes zoster virus is based largely on clinical findings and laboratory testing is not required. Acute herpes zoster virus is treated with oral antivirals, and anterior uveitis is managed with corticosteroids..
  3. In cases of retinal whitening, the physician should consider acute retinal necrosis, progressive outer retinal necrosis, cytomegalovirus retinitis, toxoplasmosis, and other posterior uveitic conditions. Diagnosis can sometimes mistake myelinated nerve fiber layer, retinal astrocytic hamartoma, and regressed retinoblastoma for a CWS

Acute retinal necrosis is usually caused by infection with herpes simplex or varicella zoster virus. Morphological distinction of these viruses can be difficult in retinal biopsies, and polymerase chain reaction (Box 9-6) or in situ hybridization (Box 9-7, Fig. 9-6) may be more helpful in providing an accurate diagnosis Less frequently choroiditis, retinitis (acute retinal necro-sis and progressive outer retinal necrosis), optic neuritis or nerve palsies can occur.
