Abstract

fetched live from OpenAlex

PURPOSE: To evaluate the effects and safety of travel by land through high mountainous elevations after surgery in patients who have undergone pars plana vitrectomy with intraocular gas. METHODS: A retrospective cohort study of 75 patients post pars plana vitrectomy with intraocular gas who traveled by land through mountain elevations of up to 3895 feet above sea level within 1 day of surgery. RESULTS: The average rate of ascent through the mountains was 29 ft/min and the maximum theoretical ocular compensation was 0.57 cubic centimeters (cc), which occurred at 4259 feet above sea level. A statistically significant change in postoperative intraocular pressure was found when compared with preoperative (P = 0.010), with two factors influencing this change: the type of gas (C3F8, P = 0.038) and lens status (pseudophakic, P = 0.010), with a mean final intraocular pressure still within the safe range. There were no cases of retinal vascular occlusion, acute elevations of intraocular pressure requiring surgical intervention, or symptomatic visual field loss attributable to elevated intraocular pressure. CONCLUSION: It seems that patients with a complete fill of intraocular gas after pars plana vitrectomy may travel safely by land through mountains with a peak ascent of 3895 feet, final ascent of 2787 feet, and a mean rate of 29 ft/min. These findings can significantly impact patient costs and convenience.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
