Abstract
Disclosed are improvements in an illuminating system for an ophthalmoscope of the type employing transillumination through the sclera of the eye. One or more fiber optic bundles convey light from a source to the sclera. Each fiber optic bundle has a physically separated tip portion of relatively small size (e.g., less than one inch long) and mass supported in a fitting. The tip portion is biased in a direction away from the main fiber optic bundle, is optically aligned therewith, and has a maximum separation therefrom of approximately 0.160 inch (4 mm). With this arrangement, a light biasing force applied to the tip portion can absorb any movement of the tip portion as it is placed in contact with the eye. The small force thus applied to the eye, even if there is minor over-exertion of pressure by the instrument operator, reduces the possibility of damage to the eye.
