Purpose Acute macular neuroretinopathy (AMN) is a visual-deteriorating rare clinical entity with an uncertain etiology. We aimed to report a case of AMN and underlying disease of acute myeloid leukemia (AML). Case presentation A thirty-five-year-old female patient with bone marrow biopsy confirmed AML, and bicytopenia, under chemotherapy, complained of sudden paracentral visual field defect in her right eye was referred. Visual acuity was 20/20 in both eyes. Posterior segment evaluation revealed multiple Roth’s spots. Optical coherence tomography (OCT) demonstrated hyper-reflectivity band, in the outer nuclear layer and outer plexiform layer, nasal to the fovea of the right eye, and hyperreflective patch in outer retina segmentation en-face OCT, suggestive of the diagnosis of AMN. Nine days after AMN diagnosis, dyspnea, malaise, and cough was initiated. Ground glass opacities in lung CT scan, beside reverse transcription polymerase chain reaction of severe acute respiratory syndrome coronavirus-2, was conclusive of coronavirus disease 2019 (COVID-19). The patient deceased after 6 days. Conclusion We report a rare case of AMN following AML. Our findings support the role of ischemia in the outer retina, of which AML may contributed to the pathophysiological process. The patient has deceased less than 2 weeks from AMN initiation.

Background: Breast and pelvic cancers are the most prevalent cancers among women globally. Several studies have reported on the effect of cell adhesion molecules on the growth, multiplication, invasion, and metastasis of tumor cells as well as inflammatory biomarkers, which are responsible for harmful inflammatory processes. Objectives: The purpose of the current study was to assess the serum levels of adhesion molecules intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin in patients with cancer before and after radiotherapy, compare these with the levels of healthy subjects, and consider the relationship of these levels with the tumor origin. Methods: The present case-control study investigated 14 patients with breast cancer and 14 patients with pelvic cancer who had been referred to Omid Teaching Hospital’s oncology clinic, Mashhad, Iran between 2015 and 2017. Evaluated by the ELISA method for ICAM-1, VCAM-1, and E-selectin were the serum samples of these 28 cancer patients before and after their course of radiotherapy treatment and the serum samples of the 28 healthy subjects who had no history of cancer, radiotherapy or the risk factor of coronary artery disease. Results: The ICAM-1, VCAM-1, and E-selectin serum levels of all patients with cancer before and after a course of radiotherapy were significantly higher than those of the control group (P value ≤ 0.5). There was no significant difference between the two cancer groups before and after radiotherapy (P value ≥ 0.05). Conclusions: The current study demonstrated that the serum levels of adhesion molecules in patients with cancer before and after radiotherapy increase significantly regardless of the initial location of the tumor.
