![Page 17: Strategies for Working with Clients with Vision Loss and Acquired Brain Injury Renee Man, CVRT/COMS Alicia Golden, OTR/L](https://reader036.vdocument.in/reader036/viewer/2022062801/56649e465503460f94b3b13d/html5/thumbnails/17.jpg)
Homonymous Hemianopsia• Field loss on the same side in both eyes– Inner half of one eye and outer half of the other– Damage to right side of brain causes vision loss on
left and vice versa– Can present as reduced acuity or complete lack of
vision and anywhere in between
![Page 18: Strategies for Working with Clients with Vision Loss and Acquired Brain Injury Renee Man, CVRT/COMS Alicia Golden, OTR/L](https://reader036.vdocument.in/reader036/viewer/2022062801/56649e465503460f94b3b13d/html5/thumbnails/18.jpg)

Other common deficits
• Dry eye– Due to slower blink rate or incomplete closure of
eye when blinking– Risk of corneal abrasions
• Double vision– May occur when eyes have trouble working
together – Dizziness often results from double vision limiting
ability to participate in therapies
