Abstract:
Critical flicker fusion frequency (CFF) is a dynamic visual function test that measures the minimum frequency at which a flicker source is perceived by the visual system as continuous light. The measurement method is convenient, the inspection time is short, and it can be effectively evaluated in the case of refractive interstitial opacity. Although CFF has many advantages, its application in the field of ophthalmology has not received sufficient attention. The pathway of CFF involves the pathway from the retina to the lateral geniculate body to the primary visual cortex, where the macrocellular pathway is sensitive to temporal resolution and responsible for transmitting rapidly changing information. Its measurements typically use red, green, or yellow light as a flashing light source to detect the functional integrity of the macular region. As a subjective test, the results of CFF can be affected by a variety of factors, such as drug use, fatigue, and luminous intensity. In order to improve the repeatability of the measurement, it is necessary to follow standardized measurement steps. CFF has important application value in the diagnosis of optic nerve diseases. It can assist in diagnosing the presence of optic neuropathy, evaluating the conduction function of the optic nerve, and monitoring the progression of the disease and the effect of treatment. As a convenient and efficient visual function evaluation tool, CFF has great potential in the diagnosis of optic nerve diseases and visual function monitoring. In view of its application prospects in the field of ophthalmology, this study calls for more attention and support from ophthalmologists, and carry out related basic and clinical research to further explore the application value of CFF in different disease conditions.
