Translation of Eye Movement Reading Training to Clinical Practice

In the proposed study, the investigators will examine whether these training exercises are effective when practiced at home. There are two specific aims in this project: Aim #1 (Year 1): to develop a web-based meta program that will administer the training exercises. For convenience, in this proposal, the investigators will refer to this platform as PAECT (Platform for Administering Eye movement Control Training). The PAECT meta program will incorporate all of the exercises that the investigators have developed and validated over the course of our previous Merit Review grants (Seiple, Szlyk et al., 2005, 2011). The PAECT platform will be designed to allow patients to easily run the training exercises in their homes and to practice at their convenience. The PAECT will employ an executive component that will keep track of the exercises that are practiced and record performance. Each time a subject opens the platform, it will choose the exercise for that subject based upon previous training and performance. The development of the software and the design of the hardware interface for administering the system will take place during the first year of the project. This will be done through a series of software/hardware iterations based upon feedback derived from direct patient testing of the system. The investigators will recruit ten patients with AMD to test and comment on the system during this phase of the project. Aim #2 (Years 2-4). To compare the effects of PAECT training on reading outcomes in two training situations: (1). training done in the clinic with feedback on performance provided by a trained low-vision therapist, and (2) training done at-home with expanded opportunity for practicing the exercises, but with no therapist feedback. Patients will be assigned to one of two groups: Patients in Group 1 ("Clinical") will undergo weekly two-hour training sessions for three months using the software/hardware system. This training will be conducted in the low-vision clinic using the PAECT, with feedback on performance provided by a trained low-vision therapist. Patients in Group 2 ("At-home") will practice all of the exercises at home using the PAECT system over a three-month period. The subjects will be encouraged to use the system as often as possible, but no less than two hours per week. Sixty patients (30 in the clinical setting and 30 at home) will be tested for each of three years.
