Inclusion criteria
Inclusion criteria: Totally Blind Group (30 participants): 1. Individuals who have undergone bilateral enucleation, have bilateral ocular atrophy, or have no light perception in both eyes for more than 3 years; 2. Visual acuity testing shows no light perception in both eyes; 3. Visual field testing shows no detectable field in both eyes; 4. Visual Evoked Potentials (VEP) in both eyes show no clear waveform; 5. Direct and consensual pupillary light reflexes are absent in both eyes (for those with eyes present); 6. Imaging confirms the absence of both eyes (for those with bilateral ocular atrophy or enucleation); 7. Age 18-60 years. Normal Control Group (30 participants): 1. Corrected visual acuity of both eyes >= 0.8; 2. Visual field and VEP within normal range in both eyes; 3. No history of ocular organic disease or surgery; 4. Age 18-60 years.
Exclusion criteria
Exclusion criteria: 1. Severe or poorly controlled systemic diseases, such as diabetes, hypertension, etc.; 2. Subjects unsuitable for this project due to psychological or sleep rhythm assessments; 3. Patients with a history of neurological disorders.
