I work at a contact lens company. I get to see all sorts of fun things while working on the website.
Progressive Outer Retinal Necrosis (PORN)
PORN is secondary to the herpes zoster virus with many patients having a recent history of dermatological vesicular lesions. Clinically PORN presents with multifocal yellowish white patches in the deeper (outer) retinal layers. These areas can become confluent leading to full thickness necrosis with subsequent multiple retinal detachments. Unlike ARN, there is minimal to no vitritis and macula involvement with a cherry red spot presentation is common. Progression is rapid and visual prognosis is poor even with medical treatment.
