Herpetic Viral Retinitis

Human Herpes Virus (HHV) is a DNA virus and is the most important viral pathogen causing intraocular inflammation. HHV is classified into types 1-8. Among these types, HHV-1, HHV-2, HHV-3 Varicella Zoster Virus (VZV) and HHV-5 Cytomegalovirus (CMV) are known to cause herpetic viral retinitis, including acute retinal necrosis and CMV retinitis. Herpes viral retinitis can be diagnosed from characteristic ocular findings and viral identification by PCR of the aqueous humor. Recently, therapy has become more effective than in the past. Herpes viral retinitis gradually progresses if appropriate treatment is not provided with regard to the patient’s immune status. Further advances in diagnostic methods and treatment are required in the future.
