Higher STOP-BANG Scores Linked to Increased Intraocular Pressure among elderly: Study
A higher value of STOP-BANG score defines a higher risk of occurrence of obstructive sleep apnea (OSA). A higher degree of STOP-BANG has a positive association with increasing intraocular pressure (IOP) in a Korean adult population aged at least 40 years. Intraocular pressure is recognized as a major risk for glaucoma, which is one of the causes of vision loss among patients. A recent study was conducted by Kim and Lee published in the Journal of Glaucoma.
The study determines the association of intraocular pressure with the risk of obstructive sleep apnea among Korean adults. The primary aim was to establish whether subjects with higher STOP-BANG scores or symptoms of OSA would have a greater chance of having an elevated IOP.
This was a population-based, cross-sectional study of adults aged 40 years or older based on the Korea National Health and Nutrition Examination Survey VIII database. The sample included 6,315 subjects between 2019 and 2021. Assessments of the risk for OSA were performed by using the STOP-BANG questionnaire, and IOP measurements were obtained by a rebound tonometer. The relationship of STOP-BANG score to the top IOP quartile is established, adjusted for lifestyle, age, sex and diabetes status through logistic regression analysis.
• Those having STOP-BANG scores from 3 to 8 had a higher odds ratio of increased IOP, by 1.27 times compared with those scoring between 0 and 2 (95% CI: 1.12-1.43).
• Among the STOP-BANG factors, loud snoring, witnessed apnea, high blood pressure, and large neck circumference were associated with a 24% to 40% increased risk of IOP elevation compared with patients without these factors.
• All four together were associated with an increase of more than a twofold of the relative risk of having high IOP compared to those with no risk factors at all (OR 2.09; 95% CI: 1.26-3.46).
In conclusion, this study strongly links high STOP-BANG scores to increased IOP in people aged 40 and older. Individual OSA risk factors such as loud snoring, observed breathing interruptions, hypertension, and wide neck circumference were significantly associated with increased IOP both as single and in combination risk factors. The findings call for the control of symptoms of OSA to lower the risk of increased intraocular pressure and its sequelae on the eye.
