Summary
A novel OCT Ophthalmoscope combines optical coherence tomography and confocal ophthalmoscopy to generate en face OCT images. This system offers new diagnostic information for retinal diseases beyond conventional imaging methods.
Area of Science:
- Ophthalmology
- Medical Imaging
- Biomedical Engineering
Background:
- Optical coherence tomography (OCT) is a key imaging modality in ophthalmology.
- Confocal ophthalmoscopy provides en face imaging of retinal structures.
- Combining these techniques may offer enhanced diagnostic capabilities.
Purpose of the Study:
- To introduce a new OCT Ophthalmoscope system.
- To demonstrate its capability of producing en face OCT images.
- To explore its potential in diagnosing retinal diseases.
Main Methods:
- A prototype OCT Ophthalmoscope was utilized.
- The system integrates OCT and confocal ophthalmoscopy, acquiring transversal OCT and confocal images simultaneously.
- Scans were performed using a super luminescent diode (820 nm).
Main Results:
- Over 800 patients with retinal conditions were scanned.
- Illustrative cases of macular diseases, including macular hole and central serous retinopathy, were presented.
- Simultaneous en face OCT and confocal imaging was achieved.
Conclusions:
- The OCT Ophthalmoscope provides novel information compared to conventional OCT.
- Future possibilities and current challenges of the en face OCT ophthalmoscope are discussed.
- The system shows promise for enhanced retinal disease diagnosis.
