A case of non-necrotising herpetic retinitis.

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.

A case of non-necrotising herpetic retinitis. / Un caso de retinitis herpética no necrosante.

In developed countries, the main origin of posterior uveitis is an infection. Herpes is the most common viral agent, as it has a wide spectrum of ocular manifestations. These manifestations may depend on the immunological state of the patient, and range from a mild focal form of non - necrotising herpetic retinitis (NNHR) to a severe form of acute retinal necrosis (ARN). A case of NNHR due to Herpes simplex virus type 2 (HSV-2) is reported, along with the different differential diagnostics prior to its diagnosis: atypical ocular toxoplasmosis, ocular tuberculosis, and ARN. During its course, despite the antiviral treatment, systemic corticoids and the clinical improvement of the injury, there was a drastic drop in the visual acuity. This event led to the re-evaluation of the suspected entities, establishing the NNHR as a definitive diagnostic by exclusion, which was a diagnostic challenge.
