Many variations occur, but scintillating scotoma usually begins as a spot of flickering light near or in the center of the visual field, which prevents vision within the scotoma area. It typically affects both eyes, as it is not a problem specific to one eye. [5] [6] The affected area flickers but is not dark. It then gradually expands outward ...
The retina lines the inside of the eye. It is light-sensitive and communicates visual messages to the brain. If the retina detaches, it moves and shifts from its normal position. This can cause photopsia, but can also cause permanent vision loss. Medical attention is needed to prevent vision loss.
The experience of amaurosis fugax is classically described as a temporary loss of vision in one or both eyes that appears as a "black curtain coming down vertically into the field of vision in one eye;" however, this altitudinal visual loss is not the most common form. In one study, only 23.8 percent of patients with transient monocular vision ...
Retinal migraine is associated with transient monocular visual loss in one eye lasting less than one hour. [1]During some episodes, the visual loss may occur with no headache and at other times throbbing headache on the same side of the head as the visual loss may occur, accompanied by severe light sensitivity and/or nausea.
Dry eyes (due to loss of corneal moisture). [24] A sense of irritation, discomfort, or pain in the eyes. A tingling sensation behind the eyes or the feeling of grit or sand in the eyes. Excessive tearing that is often made worse by exposure to cold air, wind, or bright lights. Swelling or redness of the eyes. Stare; Lid lag (Von Graefe's sign)
In an eye examination, light-colored spots on the retina are seen. Complete loss of visual acuity may happen [citation needed] The name of the condition comes from the small light-colored fundus spots on the retina, scattered in a pattern like birdshot from a shotgun, but these spots might not be present in early stages. [citation needed]
Hair loss is part of the natural three-phase hair growth cycle, which involves the anagen (growth) phase, the catagen (declining) phase and the telogen (resting) phase.
Visual auras can be simple or complex. Simple visual symptoms can include static, flashing, or moving lights/shapes/colors caused mostly by abnormal activity in the primary visual cortex. Complex visual auras can include people, scenes, and objects which results from stimulation of the temporo-occipital junction and is lateralized to one hemifield.
