Schematic comparison of routine follow-up strategies and follow-up based on analysis of VEGF concentrations.

In the routine strategy, most of the nonresponders can be identified after several anti-VEGF injections several months later, during which time devastating, irreversible vision loss can occur. Based on P-ELISA or other point-of-care (P-O-C) diagnostics, VEGF concentrations within the eye can provide the ophthalmologist with valuable information and facilitate decision-making regarding treatments options.
