H53: Visual disturbances

Visual disturbances represent a group of conditions that affect the normal way a person sees. They have various causes, such as issues with the brain, eyes, or the nerves connecting them. These conditions can change vision in numerous ways; some alter the visual field resulting in restricted or 'tunnel' vision, while others may cause blurring or dimness. Some people with visual disturbances might see flashes of light, spots, or floating objects. The progression of these conditions varies greatly; few disturbances are temporary and resolve on their own, although others may progressively worsen or become chronic. It's crucial to realize that visual disturbances can be signs of other health problems, such as migraines, retinal detachment, or neurological issues.
