The Isker spot is an optical phenomenon that was described by Russian ophthalmologist Konstantin Konstantinovich Iskersky in the early 20th century. This phenomenon was named after the scientist who first described it.
The spot is a bright spot of light that appears against a dark area. It can be caused by various reasons such as eye fatigue, lack of sleep, stress, etc. However, in most cases, the spark spot is not a sign of any disease.
In order to see the spark spot, you need to close one eye and look at some object, for example, at a wall or ceiling. Then you need to open one eye and close the other. After this, you can see a bright spot against the background of a dark space.
The Ickerian spot can be a useful tool for diagnosing certain eye diseases, such as glaucoma or cataracts. However, in order to accurately determine the cause of the isker spot, you need to consult an ophthalmologist.
Overall, the spark spot is an interesting optical phenomenon that can be useful in diagnosing certain eye diseases. However, do not forget that it is not the only indicator of eye health.
The Isker spot (Ikersky beam) is a hypothetical object, the existence of which can be assumed if the human eye had an extremely high resolution and its pupil was very wide. This hypothetical light source occurs when rays coming from different parts of the retina are imaged at the level of the macula, the last area of the visual cortex responsible for image resolution.

Around this bundle in the macula there are circuits that may be associated with information processing. On the right side, vision should be improved through the use of filtering and greater activation of neural activity and therefore active processing of the data transmitted by this bundle. While on the left, the neural pathways are activated only by almost completely suppressed data due to the proximity of the papillary fossa and some phenomena of ocular binocular effects. Thus, cortical activity is higher on the right side, which is supported by many studies designed to create visual networks and optimize visual processing.
Thus, this beam of light can serve as an experimental example of the effect of papillary and concentric cavitation.
