Hypothesis
To illustrate the potential and limitations of spectral domain optical coherence tomography (SD-OCT) in imaging retinal diseases.
Conclusion
SD-OCT imaging technology provides high-resolution images that can help in diagnosing retinal diseases with greater confidence.
Supporting Evidence
- SD-OCT revealed structural retinal changes not visible by conventional techniques.
- High-resolution images allow better visualization of retinal structures.
- SD-OCT can provide 3D images that help track changes in retinal morphology over time.
Takeaway
This study shows that a special type of eye scan can help doctors see tiny details in the eye that they couldn't see before, which can help them figure out what's wrong.
Methodology
Four selected cases of retinal diseases were imaged using SD-OCT and compared with digital fundus photography and clinical assessments.
Limitations
SD-OCT may lose details of underlying retinal structures due to shadowing from hyperreflective lesions and major retinal vessels.
Participant Demographics
The cases included patients aged 51 to 81, with histories of diabetes and hypertension.
