Abstract
The purpose of this narrative review is to study the problems in assessing visual acuity in deaf-mute children. We identified various methods of Visometry, published articles and patents for the inventions based on the assessment of visual acuity in deaf-mute children in the Russian Federation and parts of countries formerly part of the Soviet Union, in order to identify shortcomings and search for solutions. According to the total number of 126 cited scientific papers, the most common methods for assessing visual acuity in deaf–mute patients included Golovin-Sivtsev table (89.1%) and new JEI/JEI technique (8.9%). However, 2% of the doctors used tables of "illiterate" E, Teller Acuity cards with hand gestures, combining Teller Acuity cards with hand gestures to trigger reactions, Lea symbols with visual cues enabling visual cues or pointing to stimulate recognition and Graphic tables with sign language. In the presence of signs of hearing and speech disorders in patients, it is recommended to consider the use of cards duplicating optotypes to the table for assessing visual acuity
