This study reviewed 102 decisions on error reports in ophthalmic health care in Sweden between March 2017 and October 2018. The study included children, adults, women and men. We found that there was a clear association between long waiting times for ophthalmic health care and negative visual outcomes. As a result of care delay, 71 percent of the patients had moderate vision loss and 17 percent of the patients experienced severe vision loss. Patients with glaucoma and wet macular degeneration accounted for the majority of the patients with negative outcomes. Timely follow-up and prompt treatment are critical to patients' visual outcomes.
