Objective:

To identify measurable indicators that increase the risk of vision loss due to geographic atrophy (GA) and to discuss current interventions aimed at mitigating these risks.

Approach:

Key Findings:

• Larger GA lesions and multifocal lesions have higher progression rates.
• Patients with drusen near the fovea have a significantly increased risk of developing advanced AMD.
• Reticular pseudodrusen (RPD) and internal hyperreflective foci (IHRF) are associated with increased risk of GA progression.
• Lifestyle factors such as diet, exercise, and smoking cessation can influence GA progression.
• New treatments like avacincaptad pegol and pegcetacoplan show promise in slowing GA progression.

Interpretation:

Identifying biomarkers and understanding risk factors can facilitate early intervention and management of GA, potentially reducing vision loss and improving patient outcomes.

Limitations:

• The study may not encompass all potential biomarkers or risk factors, particularly emerging ones.
• Long-term effects and efficacy of new treatments require further research to validate their benefits.

Conclusion:

Early identification of GA biomarkers and appropriate interventions can significantly impact patient outcomes and slow the progression of vision loss, underscoring the need for proactive management strategies.
