The television ophthalmoscope is no longer a new instrument; the first such device was demonstrated by Ridley nearly 10 years ago.¹ Nor is the idea of ophthalmoscopy with restricted wave lengths a novel concept. The extensive investigations of Vogt with "red-free light"² and the later Work of Kugelberg³ and Kornerup⁴ utilizing photography or a photomultiplier tube have explored some of the qualitative aspects of this approach. However, the combination of television ophthalmoscopy and monochromatic illumination offers unique and hitherto unexploited possibilities for new findings particularly when the line-selector technique (vide infra) is used to obtain quantitative data. The details of equipment and procedure for such determinations together with some preliminary results are contained in the present paper.
