Impact of Environmental Factors on Glaucoma Progression: A Systematic Review
Almarzouki NClinical Ophthalmology 2024; 18: 2705-2720
BACKGROUND: Glaucoma, a leading cause of irreversible vision loss, is characterized by progressive degeneration of retinal ganglion cells. Intraocular pressure (IOP) remains a well-established risk factor, but recent research suggests environmental and lifestyle factors may also play a role. OBJECTIVE: This review aimed to evaluate the current evidence on the impact of environmental factors on glaucoma progression. METHODS: We conducted a systematic review following PRISMA guidelines, searching various databases for studies on environmental factors and glaucoma progression. RESULTS: Our review identified several key findings. IOP remains the most crucial modifiable risk factor. Aerobic exercise and mindfulness practices may lower IOP and provide neuroprotection. Lifestyle modifications like smoking cessation and balanced diets were also emphasized. Studies suggest air pollution exposure, particularly PM2.5, may be associated with an increased risk of glaucoma. However, the studies were primarily observational, and more research is needed to establish causality and elucidate underlying mechanisms. CONCLUSION: This review highlights the multifaceted nature of glaucoma, emphasizing the interplay between established risk factors (IOP) and emerging environmental influences (air pollution). Environmental factors hold promise as potential targets for glaucoma prevention and management strategies. Future research should focus on well-designed studies to investigate causal relationships and biological mechanisms.
