Challenges in HIV-Negative Cytomegalovirus Retinitis - case report.

We present the case of a 20-year-old girl with severe combined seronegative immunodeficiency who developed a bilateral decrease in visual acuity due to retinal necrosis. After further investigations, increased serological viral levels of Cytomegalovirus (CMV) were detected and confirmed the diagnosis of CMV retinitis in both eyes. After three weeks of systemic therapy with oral valganciclovir, her condition improved, with the best corrected visual acuity of the most affected eye changing from finger counting at presentation to 6/ 12. Although financial matters determined her to discontinue the antiviral treatment after three months, her ophthalmological status remained stable, and she resumed therapy after four weeks of pause. At the four months follow-up, despite an unchanged visual function, her general condition deteriorated. In the absence of appropriate treatment for her immunodeficiency both the patient's ophthalmological and systemic prognosis were poor.
