Bilateral CMV Retinitis in a Patient with Relapsed Non-Hodgkin Lymphoma on Oral Metronomic Chemotherapy: Case Report and Review of Literature

Cytomegalovirus (CMV) retinitis is one of the common complications in profoundly immunosuppressed patients such as those with acquired immune deficiency syndrome. It has been rarely reported in patients with lymphoma on aggressive chemotherapy. We encountered a patient with bilateral CMV retinitis who developed this vision-threatening complication while on low-dose palliative metronomic chemotherapy with oral drugs (cyclophosphamide, procarbazine, etoposide, and prednisolone). Though the infection resolved with treatment, there was residual vision loss. This case is presented to sensitize clinicians to the possibility of unusual infections in patients on long-term oral chemotherapies.
