Dr. Lievens is joined by Dr. Jim Williamson, who shares his journey into retinal interest and OCT technology, starting from his residency in the late ’90s. Dr. Jim Williamson discusses the evolution of OCT from the time domain to the spectral domain and swept source technologies, highlighting the significant improvements in imaging quality and diagnostic capabilities.

  • Historical Perspective: Dr. Williamson reminisces about the early days of retinal imaging, the limitations of time-domain OCT, and the transformative impact of spectral-domain OCT.
  • Technological Advancements: The conversation contrasts the older time-domain technology with the current spectral domain and swept source technologies, emphasizing enhanced image clarity and the ability to see vitreous, retina, and choroid structures in greater detail.
  • Clinical Applications: Dr. Williamson provides insights into using OCT for diagnosing and managing retinal conditions such as macular edema, epiretinal membranes, and neovascularization. He discusses how OCT technology has expanded to include peripheral retinal scans and its use in anterior segment imaging.
  • Patient Management: The discussion includes strategies for monitoring patients with partial PVD and other conditions, emphasizing the importance of regular follow-ups and patient education.
  • Future Directions: Dr. Williamson highlights the potential for further advancements in OCT technology, including the integration of multi-spectral imaging and OCT angiography (OCTA) for a more comprehensive understanding of retinal health.

Dr. Chris Lievens concludes the podcast by stressing the importance of continuous learning and staying updated with technological advancements to provide the best care for patients. He encourages listeners to explore the full capabilities of their OCT devices and to seek out educational resources to enhance their diagnostic skills.
