<unk>  presentation in individuals can be characterized by two separate phases as listed below.<unk>  Herpetic Phase The<unk>  herpetic phase is characterized by when viral particles infiltrate the retina and vitreous causing an inflammatory reaction. Together, the viral particles and mononuclear cells in the vitreous cause the retina to become opaque. In response to all this, lymphocytes and plasma cells diffuse into the vitreous as well. Late Cicatricial Phase The late cicatricial phase of<unk>  includes changes in the way the vitreous is organized due to the cellular infiltration seen in the previous phase. In the vitreous and on top of the thinned necrotic retina, contractile membranes may form. If left untreated, 50 to 75% of patients with<unk>  will experience detachment of their retina in the affected eye.
