Color Blindness

Color blindness - a person does not see colors and tones. Among diseases that deprive vision completely (hemianopsia), color blindness is the most common. The disease occurs as a result of a decrease or disappearance of color perception. A patient who is blind with color vision, due to the lack of visual information about objects, perceives the world around him in the bright colors that are familiar to him. Sometimes, with such a pathology, the patient can judge and talk about some object, but this only means some of its quality or property, mostly by sound or by taste or smell. Disorders of the functions of gnosis, praxis and ideas remain relatively intact. **Clinic.** Diseases that cause color blindness are quite common. To diagnose color discrimination, you need to examine the patient's vision using the most complex tests. Despite the fact that the main research is retinoscopy and ophthalmoscopy, they still do not give a complete picture of how much color discrimination is reduced in the person being studied. It is much more important to conduct comprehensive color tests. Therefore, for an accurate diagnosis of color, the biochemical properties of rhodopsin, as well as other indicators, should be determined. During the examination of the patient, visual acuity must be measured, and it may be necessary to evaluate vision under different conditions.
