Occlusaalisia

Occulsaalisia is a term that describes a specific type of visual impairment. It refers to a condition where an individual has difficulty seeing or perceiving objects when they are in their peripheral vision. This means their ability to detect things that are not directly in front of them is significantly reduced. It is not a general blindness but rather a limitation in the visual field.

The causes of occulsaalisia can vary. It might be congenital, meaning a person is born with the condition. In other cases, it can be acquired later in life due to damage to the parts of the brain that process peripheral visual information or damage to the retina's peripheral areas. Conditions like glaucoma, retinitis pigmentosa, or stroke can sometimes lead to occulsaalisia.

Symptoms include a tendency to bump into objects on the sides, difficulty navigating crowded spaces, and a potential for accidents when crossing streets or driving. Individuals may compensate by frequently turning their heads to scan their surroundings. Diagnosis typically involves visual field testing by an ophthalmologist or optometrist. While there is no cure for the underlying cause in many instances, strategies such as adaptive aids, environmental modifications, and specific training can help individuals manage the challenges associated with occulsaalisia.
