Inclusion criteria

Inclusion criteria: 1.Aged between 18 and 60 years, regardless of sex. 2.Best-corrected visual acuity >= 0.3 in both eyes. 3.Normal cognitive and intellectual function, with no intellectual developmental disorder or limb motor dysfunction. 4.For healthy participants, there should be no ocular diseases that may affect the visual field, such as macular degeneration or retinal detachment; no known history of brain diseases, such as epilepsy, brain tumors, or cerebrovascular diseases; and no history of major surgery or severe trauma. 5.For patients with tubular visual field loss, they should be clinically diagnosed with tubular visual field loss, or severe peripheral visual field defects such as hemianopia, and their condition should have remained stable for at least 6 months. 6.Voluntarily sign the informed consent form, understand the study content, and be willing to cooperate with the study procedures.

Exclusion criteria

Exclusion criteria: 1.Age outside the range of 18–60 years. 2.Patients who are unable to cooperate with the required examinations and have a best-corrected visual acuity of less than 0.3. 3.Intellectual developmental disorder, cognitive impairment, abnormal limb movement, or motor dysfunction. 4.Patients whom the investigator considers unsuitable for participation in this study.
