Loss in productivity due to attendance of appointments was 4.4±1.7 hours per month, with additional time lost by caregivers. Financial strain was incurred by direct medical costs associated with intravitreal assessment and injections at an average of AU$199.2±$83.1 per month. Indirect costs incurred averaged $64.8±$79.7 per month. Qualitative indirect costs due to loss of productivity for the patient, unpaid caregivers, and loss of productivity due to premature mortality were also a considerable burden. Overall mean Visual Function Questionnaire and EuroQol 5D-3L scores were correlated with visual acuity and demonstrated patients’ subjective decline in quality of vision.Conclusion: Management of nAMD carries a substantial burden on patients and caregivers. These results provide important information in understanding the effect of anti-VEGF therapy among patients with nAMD. Together with the quality-of-life burden on the patients, the management of nAMD has a significant societal impact.
