BACKGROUND

Cytomegalovirus retinitis (CMVR) is a well-described complication of CMV disease in immunocompromised hosts. While robust data exists for CMVR in patients with acquired immunodeficiency syndrome (AIDS), the incidence and risk factors for CMVR in solid organ transplant recipients (SOTR) with CMV viremia are less defined.

METHODS

We performed a retrospective cohort study of SOTR who had CMV viremia and underwent routine ophthalmologic examination between 1/1/2018 and 3/16/2022. Univariate statistics were performed to evaluate risk factors for development of CMVR.

RESULTS

Overall, 38 patients were included, primarily kidney (78.9%), heart (7.9%), and liver (7.9%) transplant recipients. Five patients (13.2%) developed CMVR during the study period. CMVR was diagnosed an average 281 days after index transplantation, 84 days from the most recent rejection episode, and 69 days from onset of viremia. Only 1 patient (20%) had symptoms at the time of CMVR diagnosis. CMVR was associated with preceding allograft rejection as well as transplanted organ type.

CONCLUSION

While CMV tissue disease more commonly manifests in other organs, CMVR occurred relatively frequently in this group of high-risk SOTR with CMV viremia. As most of the patients in our study did not have ocular symptoms at the time of diagnosis, routine ophthalmologic screening should be considered in SOTR with CMV viremia.
