Ongoing Effect of Expansion Prisms Following the Discontinuation of Use on Visual Field Enlargement and Retrograde Ganglion Cell Degeneration in Homonymous Hemianopia Patients
Sponsor: Okan University
Summary
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.

Peli prism for hemianopia
Peli prism uses high-powered prisms (40 Dioptre) that expand a hemianopic patient's awareness of their blind side. This awareness enables patients to better detect obstacles and navigate around them. Effect of the prism considered as temporary We investigated whether the effect persists after the prism is removed.To understand the persistence of the effect, we examined the changes in the visual field with CVF (Computerized visual field examination)before the prism was applied, with the prism and 1 week after the prism was removed.
