Glaucoma, a disease that can easily cause visual field defects in the eyes. In the past, glaucoma screening depended on the patient's subjective response and feelings, and lacked objective testing equipment.
Brain-puter interface (BPI) technology has unlimited potential for detecting glaucoma
Recently, a computerized brainwave reading technology has emerged in the tech industry, which is also referred to as a "brain-puter interface", and a team of researchers at the University of California, San Diego and National Chiao Tung University have collaborated to apply this technology to glaucoma. A team from the University of California, San Diego Dental School and National Chiao Tung University collaborated to apply this technology to glaucoma detection. The results of the study show that the brain-computer interface technology seems to have a lot of potential if it is applied to glaucoma screening and detection.
Traditional glaucoma screening relies on a subjective response from the patient
The authors of the study point out that glaucoma is a type of optic neuropathy, in which the degeneration of the optic nerve cells and axons causes abnormalities in the optic nerve disk, and the patient's field of vision begins to deteriorate. Traditionally, glaucoma has been assessed using a standardized automated visual acuity (SAP) test, but this test relies on a subjective response from the patient, and most of the time it is only available in medical institutions, and the patient may not necessarily recognize it as a routine test, which can lead to a delayed diagnosis of glaucoma.
Portable brain machines are portable and objective
Compared to traditional screening machines, portable brain machines are not only portable, but also objective. In this case-control study,*** 33 glaucoma patients and 17 healthy adults participated in the study, and all subjects were diagnosed with optic nerve disk stereophotography. All subjects were diagnosed with optic nerve disk stereoscopy and underwent standardized computerized autoradiography and portable encephalography over a 3-month period.
Differences in equipment, but the results were similar
In the study, the portable brain machine was a wearable, wireless device that included systems for EEG, electrooculography, and a set of head-mounted displays, which operated on a cell phone, to help detect potential responses triggered by vision ***. The study showed that the differences in the test results presented by the two groups of devices, whether conventional or portable, were not statistically significant.
Portable Brain Machine Identifies Differences Between Glaucomatous and Healthy Eyes
The authors of the study suggest that the portable brain machine may be able to assess glaucomatous visual deficits through the response to electrical currents in the brain. The device could be useful for glaucoma screening, and it could also recognize the difference between healthy eyes and glaucomatous optic neuropathy when compared with equipment used in traditional medical centers. More research is needed to see if the portable brain machine can be used for home testing, or if it can detect changes in visual field over long periods of time.
