A system of television ophthalmoscopy has been developed using commercially available colour television cameras and a specially designed high-sensitivity monochrome television camera. Funduscopy and fluoroscopy can be performed at low light levels and recorded on standard video tape for clinical evaluation and also as a teaching aid. A computerised television stereo ophthalmoscope image processor is being developed for real-time volumetric recording the volume of the optic disc cup in glaucoma.
