Purpose: To evaluate the retinal vessel density (VD) with optical coherence tomography angiography (OCTA) in asymptomatic patients affected by Waldenström macroglobulinemia (WM) without hyperviscosity syndrome (HVS) and to highlight the presence of microvascular damage in theese clinically asymptomatic WD patients. Design: Prospective study. Methods: A total of 43 eyes from 43 WM patients (24 females, 19 males, mean age 55.1 ± 13.6 years) were enrolled from January 2023 to December 2023 in the Eye Clinic of the University of Naples Federico II. .Along with WM patients, 40 healthy subjects (HS) (20 females, 20 males, mean age 52.3 ± 15.6 years) with a normal ophthalmic examination and no history of intraocular surgery or retinal pathologic features were included as control group All patients and controls underwent OCTA. Results: The two groups were not significantly different for age and sex Visual acuity examination showed no statistically significant difference in BCVA between controls and patients Compared to HS, WD patients showed lower VD values in the SCP in the whole image (47.95 ± 5.17 % vs. 52.99 ± 2.52%; p < 0.001), as well as in the parafovea (53.01 ± 6.69 % vs. 55.30 ± 2.61%; p = 0.002), and fovea (21.38 ± 9.01 % vs. 30.31 ± 5.84 %; p < 0.001). On the other hand, in the DCP VD values were significantly higher in patients compared to controls in the whole image (55.82 ± 8.07 % vs. 50.83 ± 5.46%; p = 0.005), as well as in the parafovea (56.76 ± 6.26 % vs. 52.59 ± 5.46%; p = 0.001), and fovea (38.75 ± 8.59 % vs. 33.43 ± 8.68 %; p < 0.001). Conclusion: The finding that OCTA confirmed the presence of widespread microvascular damage in WD patients clinically silent. Thus, OCTA is a safe rapid imaging technique that could represent a valid biomarker of systemic vascular dysfunction. |
