PURPOSE: To report the use of three-dimensional ophthalmoscope using optical coherence tomography (OCT) in the analysis of glaucomatous optic disc damage. CASES AND METHOD: This study involved 5 normal eyes and 10 glaucomatous eyes. The observation system comprised a scanning laser ophthalmoscope (SLO) and an OCT. Near-infrared laser was used as the light source for both SLO and OCT. The optic disc was evaluated as cross-sectional image (B-scan), and as three-dimensional image (topography). The findings were compared with those by conventional OCT. RESULTS: B-scan image analysis of glaucomatous disc was possible similar to OCT regarding resolution and time of measurement. The optic disc could be displayed as pseudo-color image, giving continuous informations regarding disc cupping. CONCLUSION: Three-dimensional OCT ophthalmoscope promises to be of value in the diagnosis and follow-up of optic disc with glaucomatous damage. LA: Japanese
