Association between regular hypnotic use and age-related macular degeneration

Area of Science:

• Ophthalmology
• Pharmacology
• Public Health

Background:

• Retinal benzodiazepine receptors are known.
• Hypnotic use may alter retinal function and increase maculopathy risk.
• Association between hypnotic medications and age-related macular degeneration (AMD) requires clarification.

Purpose of the Study:

• To investigate the association between hypnotic medication use and the risk of developing age-related macular degeneration (AMD).
• To analyze the specific risks associated with benzodiazepines and Z-meds in relation to AMD.
• To leverage UK Biobank data for a robust epidemiological study.

Main Methods:

• Assessed regular use of benzodiazepines and Z-meds (non-benzodiazepine hypnotics).
• Employed propensity score matching (PSM) to control for confounding variables.
• Utilized Cox proportional hazards regression to calculate hazard ratios (HR) and 95% confidence intervals (CI).

Main Results:

• Prolonged Z-meds use was significantly associated with an elevated AMD risk (HR: 2.15, 95% CI: 1.23-3.74).
• Regular benzodiazepine use showed no significant association with AMD risk (HR: 0.97, 95% CI: 0.73-1.30).
• Sensitivity and subgroup analyses confirmed these findings.

Conclusions:

• Prolonged use of Z-meds may increase the risk of developing age-related macular degeneration (AMD).
• Given the widespread prescription of Z-meds for insomnia, potential ocular risks warrant consideration.
• Increased monitoring for ocular health is recommended for patients on Z-meds.
