A case of non-necrotising herpetic retinitis

Abstract

In developed countries, the main etiology of posterior uveitis is of infectious origin, Herpes is the most common viral agent as it has a wide spectral of ocular manifestations. These manifestations could depend on the patient's immunologic state, ranging from a mild focal form of non-necrotizing herpetic renitis (NNHR) to a severe form of Acute retinal necrosis (ARN). We present a case of NNHR by VHS 2 and the different differential diagnostics previous to its diagnosis: atypical ocular toxoplasmosis, ocular tuberculosis and ARN. During its evolution, it presented a drastic drop in the visual acuity despite of the antiviral treatment, and with systemic corticoids and the injury's clinical improvement. This event led to reevaluate the suspected entities, establishing the NNHR as a definitive diagnostic by exclusion that constituted a challenging diagnostic.
