Obstructive sleep apnea patients having surgery are less associated with glaucoma

Area of Science:

• Ophthalmology
• Sleep Medicine
• Public Health

Background:

• Obstructive sleep apnea (OSA) is a prevalent condition with known systemic health implications.
• Glaucoma is a leading cause of irreversible blindness worldwide.
• The association between OSA and glaucoma risk requires further investigation, particularly concerning treatment strategies.

Purpose of the Study:

• To examine the relationship between obstructive sleep apnea (OSA) and the risk of developing glaucoma.
• To evaluate how different OSA treatment strategies (no treatment, surgery, CPAP, multiple modalities) influence glaucoma risk in a Taiwanese population.

Main Methods:

• A population-based retrospective cohort study utilizing the Longitudinal Health Insurance Database 2000.
• Inclusion of 2528 OSA patients and 10112 matched controls without OSA.
• Multivariable Cox regression analysis adjusted for relevant comorbidities to estimate hazard ratios (HR) for glaucoma.

Main Results:

• OSA patients exhibited a significantly increased risk of glaucoma (adjusted HR = 1.88).
• Untreated OSA patients had a higher glaucoma risk (adjusted HR = 2.15).
• Continuous positive airway pressure (CPAP) treatment was associated with a slightly increased glaucoma risk (adjusted HR = 1.65), while other treatments did not show significant differences compared to controls.

Conclusions:

• Obstructive sleep apnea (OSA) is independently associated with an elevated risk of glaucoma.
• Surgical intervention for OSA may offer a slight protective effect against glaucoma development.
• The impact of CPAP treatment on glaucoma risk warrants further investigation.
