[Photocoagulation-induced macular scotoma and automated perimetry (Octopus)].
The size of macular scotomata is determined numerically by a series of parallel F2 programs of the Octopus Perimeter. As long as useful foveolar fixation is maintained, the results are reproducible within the limits due to fluctuation of the retinal sensitivity. The scotomata can be mapped on a fundus photograph either by direct calculation or after perimetric determination of a reference distance, e.g., foveola-disc or between angioscotomata. This method furnishes useful information which can facilitate evaluation of different types of lasers in macular photocoagulation.
