Glaucoma screening: current perspectives and future directions

Abstract

Introduction: Glaucoma is an optic neuropathy with characteristic progressive optic nerve degeneration. Early detection and treatment may prevent blindness; however, the value of glaucoma screening has been debated.

Methods: Articles pertaining to glaucoma screening were reviewed.

Results: In reviewing the glaucoma literature, there is a lack of a sensitive and specific screening test and concerns over cost-effectiveness. Methods of screening include population-based screening and opportunistic case finding, which both have advantages and disadvantages.

Conclusions: Additional research is needed to better understand glaucoma progression as well as to identify improved screening tests. Consideration must be given not only to the feasibility of performing a glaucoma screening, but also to the follow-up and long-term care for glaucoma patients.
