Which technique is used to relocate the image to a healthier retinal area?

• A. Hearing aid fitting
• B. Laser therapy
• C. Glaucoma surgery
• D. Eccentric viewing or image relocation with prism

Answer: (D)

Relocating the image to a healthier retinal area is achieved by using eccentric viewing combined with prism-assisted image relocation. When the central retina (fovea) is damaged, people can learn to fixate with a different, healthier retinal region called a preferred retinal locus. Eccentric viewing trains the person to consistently use that healthier area for daily tasks like reading. Adding prisms in glasses shifts the light so the image that lands on the damaged retina is redirected toward the healthier part, effectively moving the image to a usable retinal region. This approach is a foundational strategy in low-vision rehabilitation because it makes the most of residual vision.

Hearing aid fitting has to do with hearing, not vision. Laser therapy can treat certain retinal diseases but doesn’t relocate the image to a healthier retina. Glaucoma surgery changes intraocular pressure and aims to preserve vision, not reposition the image on the retina.
