Screening of Glaucoma: Consensus and Directions.

Purpose

Glaucoma is a leading public health concern globally. This summary discusses barriers to glaucoma screening and novel strategies for a cost-effective glaucoma screening.

Methods/results: We discuss barriers to glaucoma screening and recent advancements in glaucoma detection and care, including targeted screening approach as well as telemedicine, genetic testing, and artificial intelligence (AI). A major barrier to glaucoma screening is the cost-effectiveness of case finding resulting from the low prevalence of the disease and the complexity of the diagnosis. Targeted-screening, as well as multi-level screening, can reduce the false positive rate and increase the cost-effectiveness of the program. Telemedicine, availability of genetic testing and polygenic risk scores, and AI provide the opportunity for novel glaucoma screening programs in primary care, portable, and home-based settings and will be helpful for lowering the costs, identifying patients in need of urgent treatment and enabling timely diagnosis and early intervention.

Conclusions

Screening of glaucoma is challenging and changing. Recent advancements in digital technology and genetics have led to the development of tools that are promising for novel screening methodologies. Clinical trials are needed to demonstrate the long-term effect of targeted screening on the burden of glaucoma worldwide.
