Heteronymous Hemianopia is a medical condition causing the loss of half of the visual field on different sides in both eyes. It is typically caused by a tumor on your pituitary gland exerting pressure on the Chiasma Opticum, the area above the gland where both optic nerves converge to send signals to the brain. This is a major highway for all visual stimuli, so anything that affects it will have major implications for the visual field, despite the relatively small size of the pituitary gland.
A new article from NovaVision, the vision rehabilitation division of Vycor Medical, explains how a pituitary tumor can cause major disorders like Heteronymous Hemianopia. The article goes into detail on what the disorder may look like to those that are afflicted by it and how it can affect a patient’s daily life. Several images are included to better highlight how vision is affected by this condition.
The article also gives some examples of different types of Heteronymous Hemianopia, as there are variants that affect different visual fields. While debilitating for those affected, the article concludes by saying that these symptoms typically subside after successful tumor treatment. However, if vision loss symptoms remain even after treating the tumor, NovaVision’s Vision Restoration Therapy could be the tool needed to bring that vision back to the levels they should be.
