Fluorescence ophthalmoscopy.

FLUORESCENCE ophthalmoscopy is an important manoeuvre that can provide a great deal of information about certain pathological lesions of the retina and choroid, but simple observation of the fundus appearances after intravenous fluorescein injection has tended to be neglected in favour of photographic recordings. The apparatus required for the latter is expensive and time-consuming, and often requires a special technician or trained worker. It is also, at the present stage of its development, unsuitable for small children.
