When hematology meets ophthalmology: Cytomegalovirus retinitis in pediatric stem cell recipients

Figure 1 Optimal timing and frequency of cytomegalovirus retinitis screening following hematopoietic stem cell transplantation in pediatric patients. This flow chart is adapted from published data and recommendations in three key sources: Larochelle et al[1], Ljungman et al[34], and Hakki et al[35], integrating current evidence on the timing of cytomegalovirus polymerase chain reaction testing, high-risk periods for reactivation, and indications for continued ophthalmic surveillance in vulnerable populations. CMV: Cytomegalovirus.
