From: A technique to train new oculomotor behavior in patients with central macular scotomas during reading related tasks using scanning laser ophthalmoscopy: immediate functional benefits and gains retention

Figure 5

The development, with SLO training, of a progressive uncovering strategy for reading isolated words. The figure shows three uninterrupted sequences of eye movements while reading an isolated word presented in 1.5 logMAR as seen on SLO images. Recordings were obtained in subject MT (A) before SLO training, (B) immediately after SLO training and (C) three months later. In each reading sequence images are numbered in chronological order. Before training, the subject was unable to read entirely the word "maison". He read only "mais". Immediately following SLO training, he became able to read entirely the word "horloge", performing successive eye movements uncovering segment by segment the entire word with the same retinal area (). Three months following completion of the training process, however, the subject could not anymore read entirely the word "liaison". The vertical arrow indicates the retinal area presumably being employed, here exclusively the initial PRL (). MT was, in the study, the only subject of the experiment to lose both SLO training gains, and modification of the eye movement pattern. Note that, on the SLO image, an upside down inversion of positions allows the word and the presented reading strategies to be viewed normally.
