Glaucoma is the second most common cause of blindness worldwide. The rate of glaucoma progression is highly variable; some individuals progress very slowly over many years, while others show rapidly progressing aggressive disease.
Appropriate treatment can slow disease progression and preserve vision, so early identification is essential. However, this is often challenging due to difficulties in discriminating between true change and measurement variability or natural age-related decrease in visual function. Another challenge is the lack of widely accepted and efficient gold standard criteria for establishing glaucoma progression.
Because retinal ganglion cell damage cannot be directly detected in a clinical setting, clinicians must rely on indirect methods of cell evaluation. This Focal Points
issue describes methods including standard automated perimetry, short-wavelength automated perimetry, stereo photography, optical coherence tomography (OCT) and more.
Upon completion of this Focal Points
issue, you should be able to:
- Discuss the challenges of detecting glaucoma progression
- Describe currently available clinical methods used to identify glaucoma progression and their advantages and disadvantages
- Appreciate the importance of using both functional and structural measurements in assessing glaucoma progression
Focal Points issues are practical, hands-on discussions of the clinical challenges you face daily. Each issue delivers high-quality, trusted ophthalmic information written and reviewed by leading experts.
