OBJECTIVE: To conduct a systematic review focusing on the impact of various relaxation techniques on the intraocular pressure of patients with glaucoma. METHODS: A systematic literature search was performed through CINAHL, MEDLINE, EMBASE, ClinicalTrials.gov, ProQuest Dissertations and Theses Global, and conferences until July 2022. Covidence software (Veritas Health Innovation, Melbourne, Australia) was used to conduct the systematic review. The screening was done by 2 independent reviewers, and a risk-of-bias assessment was completed after data extraction. Stata Statistical Software, version 14 (StataCorp LLC, College Station, Texas) was used to conduct a meta-analysis. RESULTS: Twelve articles (596 subjects) were included for qualitative analysis and 5 articles (332 subjects) for quantitative analysis. One hour of daily mindfulness meditation for 3 weeks resulted in the most significant reduction in intraocular pressure (IOP) at 31.8%. Meditation consistently caused long-term reductions in IOP (standardized mean difference = -2.02; range, -3.16 to -0.89). Autogenic relaxation exercises showed a trend toward reducing IOP acutely but a significant reduction in the long term. Ocular relaxation exercises combined with visual imagery of aqueous humour drainage showed both acute and long-term reductions in IOP. The effects of yoga on IOP could depend on the positions being practiced. CONCLUSION: Various relaxation techniques, such as meditation, visual imagery, autogenic relaxation exercises, and ocular relaxation exercises, seem to cause significant reductions in IOP. Future randomized, controlled trials should be carried out to further explore the utility of these techniques for patients with glaucoma.
