What treatment strategy does the PrONTO AMD study show leads to fewer injections without compromising visual acuity outcomes?

The PrONTO AMD study demonstrated that OCT-guided treatment can effectively reduce the number of injections required while maintaining visual acuity outcomes for patients with age-related macular degeneration (AMD). This approach involves the use of optical coherence tomography (OCT) to monitor the progress of the disease and tailor injections based on the individual patient's needs. By assessing the anatomical changes in the retina, clinicians can decide to administer injections based on specific criteria rather than on a fixed schedule. This flexible strategy helps to prevent overtreatment and minimizes the burden of frequent visits for patients, ultimately leading to fewer injections without sacrificing visual acuity.

In contrast, fixed dosing relies on a predetermined injection schedule that may not consider the patient's changing condition, potentially leading to unnecessary treatments. Monthly injections represent a more traditional approach that may not be as efficient in reducing treatment burden. While emergency intervention refers to immediate treatment in acute cases, it does not pertain to the ongoing management illustrated in the PrONTO study. Thus, OCT-guided treatment stands out as the most effective method according to the study's findings.
