Inclusion criteria
Inclusion criteria: 1. Diagnostic Criteria:?? Patients must be diagnosed with concomitant strabismus by a professional ophthalmologist, with detailed strabismus angle measurements and ocular examination results serving as diagnostic evidence; 2. Age Range:?? Study participants must be aged 1 to 80 years; 3. Gender:?? No restrictions; both male and female patients may participate; 4. Eye Involvement:?? Patients with unilateral or bilateral strabismus are eligible; 5. Surgeon Classification:?? Surgeons are categorized by experience: ?Expert Group:?? >10 years of surgical experience; ?Intermediate Group:?? 5–10 years of surgical experience; Novice Group:?? <5 years of surgical experience; 6. Surgical Protocol:?? All procedures must be planned based on preoperative strabismus angle measurements and ocular examinations, including: recession or resection of lateral rectus muscle, recession or resection of medial rectus muscle and disinsertion of inferior oblique muscle; 7. Anesthesia:?? Anesthesia methods are unrestricted (e.g., general anesthesia or target-controlled anesthesia). Detailed records of anesthesia type, dosage, and patient response are required; 8. Patients were excluded if they had severe ocular comorbidities (e.g., glaucoma, severe retinopathy, ocular trauma, etc.), underwent ophthalmic surgery within the past year, had systemic diseases, or were unable to cooperate with postoperative follow-up.
Exclusion criteria
Exclusion criteria: 1. Insufficient Image Clarity:?? Exclude video segments with persistent blurring, severe defocusing, or inadequate lighting that obscure details, ensuring overall visual clarity; 2. Compromised Integrity:?? Remove videos rendered discontinuous due to corruption, data loss, or transmission errors, guaranteeing completeness from start to finish; 3. Abnormal Playback Rate:?? Exclude all videos subjected to non-standard speed alterations (e.g., fast-forwarding, slow motion), preserving consistent and accurate time progression; 4. Evidence of Editing/Tampering:?? Employ technical methods to detect and exclude videos with signs of cutting, content splicing, or artificial modifications, maintaining data authenticity; 5. Improper Framing:?? Exclude videos where subjects persistently deviate from the frame center or critical parts frequently exit the visible area, ensuring analyzed targets remain fully observable within the frame; 6. Visual Occlusion Issues:?? Exclude videos with prolonged obstructions (e.g., tears, foreign objects) affecting key areas like the eye—not limited to severe bleeding; 7. Missing Initial/Final Actions:?? Ensure videos comprehensively capture the entire process from operation/event initiation to conclusion, with explicit emphasis on retaining the first and last critical actions; 8. Extraneous Visual Interference:?? Exclude videos containing superimposed elements (e.g., subtitles, timestamps, watermarks, graphical markers) that may impede analysis—unless uniformly present and non-obstructive across all videos.
