Anterior Segment Optical Coherence Tomography

 

Sight is one of the most important senses that we use and need in daily living. My team used Anterior Segment optical coherence tomography (the AS-OCT) during our clinical placement and realised the resolution of captured images can really affect clinicians' judgment and diagnosis. Agent injection was used to improve the contrast of the intraocular structures but we wanted to develop a non-invasive technique that is patient-friendly. Knowing that dA has been applied in OCT images of the posterior pole which is the back of the eye, we decided to use the same method for OCT images of the anterior part of the eye and enhance the image.

Domain Expertise:
Optometry
  • Toby Chan is studying optometry at PolyU, which is the domain knowledge of eye care, vision testing, and ocular health.
Anterior Segment Optical Coherence Tomography
  • Toby and his team conducted research using AS-OCT, a new technology used in clinical practice to examine the anterior ocular structure non-invasively.
Image Enhancement
  • Toby's research project focused on the effect of image enhancement on the accuracy of evaluating anterior chamber angle (ACA) in AS-OCT images. This domain knowledge involves techniques to improve the quality and resolution of digital images.
Ocular Structure Evaluation
  • Toby's research project aimed to improve the evaluation of ocular structures, particularly the anterior chamber angle, using AS-OCT images. This requires understanding the anatomy and characteristics of the eye's anterior segment.
Digital Technology in Medicine
  • Toby's research involved applying digital image enhancement techniques to medical imaging, which is a domain knowledge that intersects optometry with digital technology and medical image processing.

 

Lifelong Learning Excellence:
Research and Information Literacy
  • Toby engaged in a research project on the effect of image enhancement on the accuracy of evaluating anterior chamber angle (ACA) in anterior segment OCT (AS-OCT). He and his team conducted research, collected data, and analyzed the results, gaining valuable experience in the research process.
Critical Thinking and Problem-solving
  • Toby mentioned that he had to manage his time effectively to balance the research project with other academic commitments like clinical placement, practical exams, and written exams. He created a time schedule and set deadlines for completing tasks, allowing him to stay on track.
Project Management and Teamwork
  • Toby encountered difficulties during the project, including deciding on the research topic, recruiting subjects during the COVID outbreak, and learning computerization and digital enhancement. He and his team had to address these challenges through problem-solving and effective decision-making.
  • Toby emphasized the importance of teamwork in completing the research project successfully. Collaborating with his teammates allowed them to share responsibilities, pool their strengths, and complete the project smoothly.
Continuous Improvement and Learning from Mistakes
  • Toby acknowledged that the research project took him out of his comfort zone, as it involved topics not covered in their optometry courses. Despite the challenges, he was willing to learn and adapt, gaining knowledge beyond his specialization.
Communication and Presentation Skills
  • Though not explicitly mentioned, effective communication is implied as Toby had discussions with his team members and supervisors, and they patiently guided him throughout the project.
