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.

Traumatic Brain Injury (TBI), specifically concussions, is a major health problem in Malaysia, particularly among young adults. After a concussion, individuals often experience Post Trauma Vision Syndrome (PTVS), which can cause symptoms such as dizziness and difficulty coordinating the eyes due to brain damage. PTVS can impact reading skills, balance, and result in headaches or migraines, as well as problems with eye movement, focusing, and convergence. Neuro-Optometric Vision Rehabilitation is a treatment program that assists patients in improving their visual function by addressing these issues.
Children with reading and writing difficulties may be misdiagnosed with dyslexia when the issue is actually related to their eyesight. Dyslexia affects reading abilities in intelligent individuals, but some children may have both dyslexia and vision problems, while others only have issues with their eyesight. Three common eye problems can mimic dyslexia symptoms: difficulty with left and right directions, visual fatigue, and poor eye movement control. Experts in both dyslexia and eye problems should evaluate the child to accurately differentiate between the two. In some cases, a child may have both dyslexia and an eye problem, requiring separate solutions. Consult professionals specializing in dyslexia and eye therapy for the correct diagnosis and treatment.
Researchers at Saarland University have developed a new therapy for “binocular fusion dysfunction,” a condition that disrupts the brain’s ability to merge images from both eyes, causing vision problems. This condition affects around 20% of stroke patients and up to 50% of those with brain injuries. The therapy involves a six-week training program that helps improve coordination between the eyes. After the training, all participants showed significant improvement in merging images and depth perception. The findings also suggest that damaged brain areas could recover with appropriate therapy.
