What is this summary about?
This is the summary of an article published in Ophthalmology Retina. This summary presents results from a study that used information from a United States (US) healthcare database to look at how intravitreal injections (injections into the eyeball) of anti-vascular endothelial growth factor (anti-VEGF) may affect vision for patients with either neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME). The study focused on maintaining driving vision over 4 years.
What happened in this study?
Researchers looked at information in the Vestrum Health database to identify patients diagnosed with nAMD or DME between January 1, 2014 and June 30, 2019 and had medical records that showed how their vision changed while they were receiving anti-VEGF treatment.
What were the results?
Vision improved for both nAMD and DME patient groups in the first year of anti-VEGF treatment but then got worse over the next 3 years. Patients with nAMD or DME who had more anti-VEGF injections in the first year of treatment had a higher chance of maintaining their driving vision. Both groups of patients were more likely to lose their driving vision if they were older or had worse vision before starting treatment.
What do the results mean?
These results show that starting anti-VEGF treatment early and having frequent injections is important for keeping driving vision in patients with nAMD or DME. Currently, patients with nAMD or DME may not be getting injections early and often enough to maintain their driving vision over the long term.
