Clinical and Virological Characteristics and Prognostic Factors in Viral Necrotizing Retinitis.

Clinical factors including advanced age, immunocompetence, low BCVA and high vitritis grade at baseline were associated with a poor prognosis. New virological factors were predictive of a poor outcome: high baseline VL and the "slow responder" status. Sequential intraocular fluid sampling might help prognosticate the outcomes of VNR.
