Night Blindness

Night Blindness is the inability to distinguish surrounding objects in dim light or at night. This condition develops as a result of damage to the rods of the retina, which are responsible for vision in dim light. The cause may also be a deficiency of vitamin A in the body.

If vitamin A deficiency is not corrected in time, the condition can worsen significantly. Dangerous diseases such as xerophthalmia and keratomalacia may develop.

Night blindness can also be associated with other retinal diseases, such as retinitis pigmentosa.

The medical name for this condition is nyctalopia.

Unlike night blindness, day blindness affects the ability to see in bright light.

Night blindness is the inability to distinguish surrounding objects at night or in low light. It can be caused by various reasons, such as damage to the retinal rods responsible for dark vision, or vitamin A deficiency. If left untreated, this problem can lead to serious consequences such as xerophthalmia and keratomalacia. Night blindness may also be associated with other retinal diseases, including retinitis pigmentosa.

The blind spot is the largest tumor I have ever seen in the clinic. Its dimensions are 3x2 centimeters, the shell is light brown in color, from which a fetid odor emanates, the eyes protrude from their sockets. The patient refused many operations due to fear of death. When the tumor was removed, it was discovered that many vessels had been cut. The patient did not recover.

Dezveglia, Nikolai Lvovich, page 612 The article describes the practice of surgical removal of a tumor complicated by blindness in a patient. The conclusion that the author draws from practice is the inability to trust medicine in your own life, including your health. According to Nikolai Lvovich, the surgical method at this stage of development of medicine is far from the only one. This is due to the fact that the operation often leads to complications.

Mikhail Sergeevich Segal. Blindness. The name of the city is not mentioned. Medicine as a mortal danger The author describes the case of a blind woman and a doctor who decides to undergo surgery to remove a tumor. However, during the operation itself, the author describes the behavior of a nurse who, after taking anesthesia, removes the sponge. Mikhail Sergeevich is a supporter of other treatment methods.
