Different fixation alternatives marked on a computor screen.Abstract.

The MoviText method has been developed and tested on individuals with absolute central scotomas as a pre-optical reading training method. The ZoomText computer screen magnification software with its DocReader feature has been used in reading training to show the effect of moving the text during reading. The user reads with his or her selected eccentric angle viewing in order to acquire the new eccentric reading behavior more easily, before optical devices are introduced. Nine subjects in this study used microscopic lenses from 6X to 13X magnification as reading devices. The subjects, all with very large central visual field losses, achieved a significant improvement in reading rate when using the microscopic lenses after training with the new MoviText method.
