Assessment of retinal, choroidal and peripapillary microvascular changes in patients with chronic myeloid leukemia.
Observational study in Japanese journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo quantitatively assess the microvascular alterations and structural parameters in the optic disc, retina, and choriocapillaris of chronic myeloid leukemia (CML) patients devoid of leukemic retinopathy, while also examining the correlation between these parameters and serum laboratory results. STUDY
designProspective, cross-sectional, observational clinical study
methodsThis study included 30 eyes from 15 patients diagnosed with CML and 30 eyes from age 15- and gender-matched healthy individuals (control group). All participants underwent comprehensive ophthalmologic assessments, including optical coherence tomography angiography (OCTA). Statistical analyses, including Student's t-test and the Mann-Whitney U test, were conducted to compare structural and vascular parameters between CML patients and controls. Spearman's correlation was used to evaluate the relationship between OCTA measurements and serum parameters.
resultsThe analysis of macular vessel density revealed significant reductions in all assessed parameters in the patient group compared to the control group. These parameters include whole image superficial vessel density (wisVD, p=0.005), parafoveal superficial vessel density (pfsVD, p=0.002), perifoveal superficial vessel density (pefsVD, p=0.007), whole image deep vessel density (widVD, p=0.005), parafoveal deep vessel density (pfdVD, p=0.004), and perifoveal deep vessel density (pefdVD, p=0.005). Higher white blood cell levels were associated with lower optic nerve head whole image VD, wisVD, pfsVD, pefsVD, widVD, and pefdVD. Higher platelet levels were correlated with lower widVD. Additionally, hemoglobin showed a positive correlation with choriocapillaris vessel flow density, while it exhibited a negative correlation with superior and inferior macular ganglion cell complex thickness.
conclusionSubclinical retinal perfusion loss was observed in CML patients, and this perfusion loss was associated with hematological parameters. The marked reduction in macular perfusion could be valuable for understanding the pathogenesis of the disease and predicting potential retinal complications such as hypoxia and ischemia in more advanced stages. Further studies are needed to investigate the functional and prognostic significance of the changes we observed.
