VITREOUS VIDEOGRAPHY USING THE SCANNING LASER OPHTHALMOSCOPE (REPRINTED WITH PERMISSION FROM AMERICAN-MEDICAL-ASSOCIATION, COPYRIGHT 1995)

To establish the method of vitreous videography using the scanning las er ophthalmoscope, we observed the vitreous in patients with age- or d isease-related vitreous changes. We compared the results using four la ser wavelengths. The detailed structures of the posterior vitreous cor tex, a premacular defect, and a prepapillary glial ring were clearly s hown under direct laser illumination. A short wavelength laser was fou nd to be superior to a long wavelength laser for observing the posteri or vitreous cortex. Vitreous opacities were clearly shown as dark spot s under retroillumination using any of the four laser wavelengths. In vivo visualization of the vitreous was achieved using this new techniq ue, which is superior to conventional biomicroscopy because of its mon ochromatic laser delivery system and confocal light detection capacity .
