Population-based study. All patients 66 years of age and older in Ontario, Canada, receiving first-ever therapy for glaucoma with either LT or topical medication between April 1, 2007, and March 31,2019. Linked health care databases were used to identify patients receiving first-line glaucoma therapy and to ascertain patient-level factors potentially associated with receipt of LT versus medication. Multivariate logistic regression analyses were undertaken. Factors associated with receiving LT versus medications were evaluated using adjusted odds ratios (ORs) for age, gender, previous cataract surgery, previous corneal transplantation, previous retina surgery, level of systemic comorbidity, socioeconomic status (SES), and rural versus urban residence. In total, 194 759 patients were included. Older patients were less likely to be treated with LT versus medicati factors related to patient demographics, ocular history, and comorbidity. Many of these associations are unexpected based on efficacy data or evidence-based guidelines. These results are topical considering growing evidence supporting use of first-line LT. Our results identified patient characteristics associated with use of LT as primary therapy for glaucoma, including factors related to patient demographics, ocular history, and comorbidity. Many of these associations are unexpected based on efficacy data or evidence-based guidelines. These results are topical considering growing evidence supporting use of first-line LT.Photon-counting computed tomography (PCCT) is an emerging technology promising to substantially improve cardiovascular imaging. Recent engineering and manufacturing advances by several vendors are expected to imminently launch this new technology into clinical reality. Photon-counting detectors (PCDs) hav
