Landolt Table

The Landolt table is an instrument used in ophthalmology to measure the angle of strabismus. It was developed by Swiss ophthalmologist Ernst Landolt in the 19th century.

The Landolt table is a sheet of paper on which there are two lines intersecting at an angle of 45 degrees. The patient should look at the lines and try to focus on them without turning their head. The doctor then measures the angle between the lines on which the patient's eye focuses.

Using the Landolt table allows you to determine the degree of strabismus and choose the most effective treatment method. For example, if the squint angle exceeds 30 degrees, surgery may be required.

In addition, the Landolt table can be used to assess the effectiveness of strabismus treatment in children and adults. This allows the doctor to determine how successful the treatment is and what changes need to be made to the treatment program.

Thus, the Landolt table is an important tool in ophthalmological practice and allows you to accurately determine the angle of strabismus, which can help the doctor choose the most effective treatment method.

Landolt Tables is a test for determining visual acuity, which is based on the correspondence between the brightness of objects and their distance from the eyes. Landolf proposed this method of testing vision in the early 20th century, while other ophthalmologists tended to test vision using charts with symbols.

Landolft's method was tested on small groups of people with various eye diseases, after which it was concluded that it was the most effective method for determining vision. Moreover, it is easy to use and very fast in time. It became popular in Europe due to its pro-aeration effect. The Landolf tablet was introduced into medical practice to evaluate vision. But it has some disadvantages due to the fact that the pupils of the eye may differ from the norm.
