Reunalistus

Reunalistus is a term that describes the phenomenon of seeing peripheral or marginal visual phenomena that are not objectively present. This can manifest as a variety of visual disturbances, including seeing shadows, flickers of light, or even vague shapes in the corner of one's eye. These experiences are often fleeting and can be difficult to pinpoint.

The exact causes of reunalistus are not fully understood and can be attributed to several factors. In many cases, it is a normal physiological occurrence related to how the eyes and brain process visual information. The periphery of the visual field is less sensitive to detail and color than the central field, and the brain may sometimes "fill in" or interpret ambiguous stimuli in a way that creates these illusory perceptions. Fatigue, stress, and changes in lighting conditions can also exacerbate reunalistus.

However, reunalistus can occasionally be indicative of underlying medical conditions. Ocular issues such as retinal detachment, glaucoma, or optic nerve problems can sometimes present with peripheral visual disturbances. Neurological conditions affecting the visual pathways in the brain, like migraines with aura, or even more serious conditions, might also be associated with these types of visual experiences. If reunalistus is persistent, accompanied by other symptoms like pain or vision loss, or causes significant distress, it is advisable to consult a healthcare professional for a proper diagnosis and evaluation.
