Hemianopia, refers to the loss of vision in either the entire left or right half of the visual field. Common causes of this condition include stroke side effects, brain tumors, and traumatic injuries. This vision loss can lead to various challenges in daily life, such as difficulty with movement, accidental collisions with objects, increased risk of falls, unexpected mishaps, and struggles with reading.
Findings from the National Health and Nutrition Examination Survey (1988-1994) revealed that 1 out of every 1000 individuals examined had Hemianopia. Moreover, approximately one-third of individuals undergoing stroke rehabilitation experience either homonymous Hemianopia or spatial neglect.

Intervention
The Peli Lens™ stands out as the latest and most effective prism technique, offering a significantly wider stroke visual expansion field compared to other options: originally 20˚ and now an expanded 30˚ in the latest design. These advancements are supported by clinical trials.
Vision therapy focusing on training for scanning.
Based on clinical studies, patient success rates, the expansion characteristics of the stroke visual field, and cost-effectiveness, the Peli Lens™ emerges as the primary choice for most individuals with Hemianopia. However, the other methods mentioned remain viable alternatives should the patient not adapt well to the Peli Lens™.

A person with Hemianopia, having vision only on the left side of both eyes, might easily stumble upon a hidden obstacle, like a trash bin, since it’s not visible within their blind field. If there were a way to signal the presence of such obstacles in the blind field, they could be avoided.
The “EP” or Expansion Prism system
The “EP” system aims to assist in identifying obstacles, particularly during movement, rather than serving as a tool for reading support. The fitting process for the patient is straightforward and economical, following the provided fitting protocol and making necessary adjustments while the patient walks during training. After this, the patient is sent home to make further adjustments for approximately one month.

Optometrists label themselves as behavioural because vision issues can affect behaviour, causing avoidance of tasks like reading due to fatigue and headaches. They’re called developmental optometrists because they assess and treat the progression of visual skills like focusing and comprehension through vision therapy.
Functional vision problems can significantly affect a child’s performance in reading, writing, and arithmetic. These issues are often not detected by standard school vision screenings but can greatly impact a child’s academic and social life. Vision problems can hinder a student’s ability to recognize and remember numbers and letters, affecting comprehension. It may also lead to difficulties in deciphering decimals and signs in math, and challenges in writing in a straight line or distinguishing similar-shaped letters. To identify these issues, it is recommended to seek advice from a developmental optometrist for a comprehensive functional vision assessment.
Functional vision issues, which involve the brain, eyes and visual pathways working together, can cause difficulties in reading and writing for children. These problems may not be detected by conventional eye examinations and can include poor convergence, laterality, form discrimination, span of recognition, visualization, tracking, orientation, and focusing. Vision therapy, involving exercises and various tools, is an effective treatment for improving these underperforming visual skills.
