Abstract
PURPOSE
To study the posterior segment complications (PSC) and the risk factors in patients after allogeneic hematopoietic stem cell transplantation (HSCT).
METHODS
This cross-sectional, case-control study enroled 143 patients who received allogeneic HSCT. Comprehensive ocular examinations were performed to evaluate PSC and ocular Graft-versus-Host Disease (oGVHD). PSC was diagnosed based on the characteristic fundus findings and auxiliary examinations. Visual-evoked potential was examined in patients with unexplained visual loss and suspected visual pathway pathology (VPP). Ocular surface disease index, corneal fluorescein staining, conjunctival injection and Schirmer's test were scored to diagnose oGVHD.
RESULTS
PSC was detected in 36 (25.2%) patients, while 107 (74.8%) patients were not. Among them, 102 (71.3%) patients were diagnosed with oGVHD. The most common PSC included cytomegalovirus retinitis (13/143, 9.1%) and VPP (7/143, 4.9%). Central nervous system relapse of leukaemia was detected in four out of seven cases of VPP. Patients with PSC had worse visual acuity, lower prevalence and milder severity of oGVHD, and more donors from unrelated and human leucocyte antigen (HLA)-mismatch (all P < 0.05). PSC was associated with transplant from unrelated (OR = 6.494, 95% CI: 1.635-25.794, P = 0.008) and HLA-mismatched (OR = 7.193, 95% CI: 2.829-18.291, P < 0.001) donor but not with the occurrence of systemic GVHD or oGVHD.
CONCLUSIONS
PSC in post-HSCT patients was more common than previously noted, deserving the concern of ophthalmologists, especially in patients with unrelated or HLA-mismatched donors.
