Evolution of threshold character size for single letters and isolated words. Threshold character sizes' values in logMAR, are provided for each subject. before: before SLO training; after: immediately after SLO training; three months later: three months following SLO training. Isolated letters and word length categories are considered independently. With subject GM, threshold character size for 6 and 7 and 9 and 10 letter words could not be determined before training, because he was unable to decipher the largest presented stimuli (1.5 logMAR). Therefore, in the graph, he was assigned the minimum 1.6 logMAR level. Note the invariance of the results for isolated letters, contrasting with the variability of the changes obtained for isolated words. Loss of training gains mainly occurred when deciphering longer words. In this regard, measures in subject LG are particularly illustrative, showing continuous improvement in reading single letters and 3/4-letter words, stabilized performance for 6 and 7-letters words, results which contrast with the gain loss observed for 9 and 10-letter words.
