G. Strasser, VIDEO-STEREO-PHOTOGRAPHY OF THE OPTIC DIS C - ITS APPLICATION TO CLINICAL-PRACTICE, Klinische Monatsblatter fur Augenheilkunde, 210(3), 1997, pp. 8-9
Video documentation of the posterior pole using a camera installed in
the ocular part of a slitlamp provides visualization of the optic disc
from two different angles by changing the ocular part with the camera
from the right to the left. Using the appropriate video printer progr
am (split 4) two pictures of the right optic disc are stored on the up
per half, one shooting from the right the other from the left. The low
er half of the print is reserved for the left optic disc. Thus stereos
copic perception of the optic discs can be achieved. By this means a s
imple procedure has been provided for improved follow up of glaucoma p
atients.
