Trial with red filter in the treatment of eccentric fixation.

Abstract

FOLLOWING the preliminary reports of Brinker and Katz (1963) and Binder, Engel, Ede, and Loon (1963) on the possible use of a red filter in the management of eccentric fixation, we tried this method of treatment in a series of eighteen cases, ten of which completed the investigation. Six of these were cases of eccentric fixation of the paramacular type, two of the parafoveal type, and two were cases of fixation loss. Our results are compared with those of the authors named above and with the results of a recent survey on pleoptic treatment. No attempt was made to differentiate between eccentric fixation and eccentric viewing in any of these investi- gations or in our own work.
