Surgical Dosage Formulas For Convergence Insufficiency Exotropia

This dataset compares surgical outcomes for 138 patients with convergence insufficiency-type intermittent exotropia using two different formulas for monocular lateral rectus recession–medial rectus resection (RR). It contains results from a retrospective review with at least 6 months of follow-up, tracking deviation angles and success rates up to 24 months post-operation.

Use Cases

• Compare surgical success rates at 24 months between the two formula-based groups (Group 1 and Group 2).
• Analyze the reduction in near-distance difference (PD) from preoperative to 24-month postoperative measurements.
• Model the relationship between exodeviation at distance and the amount of lateral rectus recession in the symmetric RR formula (Group 2).
• Examine the temporal pattern of esodeviation at distance and near across postoperative time points (1, 3, 24 months).

Strengths

• Contains data from 138 total patients (58 in Group 1, 80 in Group 2).
• Includes longitudinal data with follow-up measurements spanning at least 6 months up to 24 months post-operation.
• Reports specific clinical metrics like deviation angles in prism diopters (PD) and statistical significance (p-values).

Limitations

• Small sample size of 138 patients limits statistical power for subgroup analyses.
• Retrospective study design may introduce selection bias compared to a randomized controlled trial.
• Dataset scope is limited to a single surgical procedure (RR) for a specific eye condition (CI-type IXT).
