Fluorescein angioscopy: techniques of partial fluorescence, permanent drawing record and photocoagulation.
Fluorescein angioscopy with the indirect ophthalmoscope might be the preferred technique for evaluating and treating certain lesions, particularly those in the retinal periphery. Three techniques which are helpful in extending the advantages of angioscopy are described. (1) Partial fluorescence is achieved with careful adjustment of the cobalt blue filter which relates the fluorescence to retinal landmarks, ie, color angioscopy. (2) A permanent record of angioscopy in different phases can be made with tracing paper over the retinal drawing. (3) Correct localization of lesions to be coagulated is achieved with blue filters over the coagulator beam following fluorescein injection. The filter is removed during coagulation.[1]References
