Ongoing Effect of Expansion Prisms Following the Discontinuation of Use on Visual Field Enlargement and Retrograde Ganglion Cell Degeneration in Homonymous Hemianopia Patients

The goal of this observational study is to learn about the long-term effects of Pelli prism in Hemianopia patients who take Prisms for awareness of the area they cannot see. The main question it aims to answer is: Does the field enlargement observed with the prism continues after the prism is removed? Participants already using Peli prisms as part of their regular medical care for Hemianopia, in the upcoming routine controls their field of vision enlargements will be examined.
