Statins and lower glaucoma risk: an association, not a prevention prescription
At 07:34 Beijing time on October 7, Eric Topol asked whether statins prevent glaucoma, linking a British Journal of Ophthalmology study. It compares existing TriNetX records retrospectively, without randomly assigning medication.
After matching, the incidence analysis retained 210,701 people in each group, over 40 with ophthalmological records. At five years, new diagnoses numbered 4,771 (2.3%) among statin users and 5,491 (2.6%) among controls. The hazard ratio was 0.85 (95% confidence interval 0.82–0.89). The relative association is not a 15-percentage-point reduction; the crude proportions differ by about 0.3 points.
Matching cannot remove unrecorded confounding such as adherence and dose. Eye pressure, visual fields and optic-nerve images were unavailable; treatment escalation in a separate analysis does not directly measure progression. The authors call for prospective randomized trials. The morning discussion provides no new indication to start a cholesterol drug for glaucoma prevention.
