Choroidal vascular and oropharyngeal morphological indicators in predicting CPAP treatment efficacy in severe OSAS patients: a prospective cohort study

In the Poor response group, the longest apnea duration (LAD), percentage of time with oxygen saturation < 90% (TS90%), and apnea-hypopnea index (AHI) were all significantly higher than those in the Good response group. The lowest arterial oxygen saturation (LSaO2) was notably lower in the Poor response group compared to the other one (P < 0.05). The area under the curve (AUC) values of SF-CT, CC-VD, and CVI for predicting the outcome of IBD patients were 0.835, 0.805, and 0.910, respectively. The AUC values of PNS-Me, HMD, and PNS-P1 were 0.897, 0.937, and 0.898, respectively. In addition, the nomogram prediction model constructed with choroidal vascular and oropharyngeal morphology indicators had high accuracy. CONCLUSION: Choroidal vascular and oropharyngeal morphological indicators have a good predictive effect on CPAP treatment efficacy in patients with severe OSAS.
