Objective: To focus on the visual function and outcomes of the patients with some residual vision implanted with the Argus II Retinal Prosthesis.
Materials and Methods: Two groups of patients were identified (patients without and with some residual vision) and the functional vision of the two groups were measured with two visual function tests (Square Localization and Direction of Motion) that were designed to evaluate a patient’s ability to locate an object and determine the direction of an object moving in the visual field. Daily life’s outcomes of these two groups of patients were based on the Functional Low-Vision Observer Rated Assessment (FLORA).
Results: The analysis focused on patients implanted with residual vision compared to patients without residual vision and the results show that the Argus II system gives benefits to both group of patients in terms of performances on the visual function tests and also in terms of mobility and daily living.
Discussion: The investigation demonstrates that patients with residual vision are able to combine the artificial vision and their own residual vision, allowing them to have better performances than patients with no residual vision in their daily living.
