Loss to follow-up and increase in cup-to-disc ratio among glaucoma patients in the IRIS Registry.

Key Points

• The aim is to examine the relationship between loss to follow-up and changes in the cup-to-disc ratio among patients with primary open-angle glaucoma.
• Analyzed data from the IRIS Registry
• Identified patients with primary open-angle glaucoma
• Monitored changes in cup-to-disc ratio over time
• Computed incidence of loss to follow-up
• Patients experiencing loss to follow-up showed a higher rate of increase in cup-to-disc ratio.
• Loss to follow-up was confirmed as an independent risk factor for worsening cup-to-disc ratio.
• Significant correlation between follow-up continuity and maintaining stable cup-to-disc ratios.
