Bacillary Layer Detachment in nAMD: A New Piece of the Puzzle

This recent study sheds light on an interesting finding in patients with neovascular age-related macular degeneration (nAMD): bacillary layer detachment (BLD). This detachment, observed in 7.2% of patients, seems to offer insights into disease severity and response to treatment.

Key Takeaways:

  • BLD is an optical coherence tomography (OCT) finding characterized by splitting within the photoreceptor layer.
  • Patients with BLD had worse vision, thicker maculas, and more fluid buildup compared to those without BLD.
  • Anti-VEGF therapy effectively resolved BLD in most cases, reducing fluid and improving vision.
  • However, patients with BLD never fully recovered their vision to the level of those without BLD.
  • Eyes with BLD exhibited higher fluctuations in fluid levels, suggesting more dynamic disease activity.


  • BLD could be a biomarker for more severe nAMD and worse visual outcomes.
  • Identifying BLD at the start of treatment may help tailor therapy and adjust expectations.
  • Monitoring fluid level fluctuations in BLD patients could inform treatment decisions.
  • Including/excluding BLD patients in clinical trials might be necessary depending on study goals.

Looking Ahead:

  • More research is needed to understand the causes and long-term implications of BLD.
  • Developing personalized treatment strategies for BLD patients is crucial.
  • Investigating BLD as a potential predictor of response to different anti-VEGF agents could be valuable.

Overall, this study highlights the importance of advanced imaging techniques like OCT in understanding nAMD and optimizing treatment approaches.
