Summary
In advanced primary open-angle glaucoma, the 24-hour IOP rhythm shifts to peak at night rather than during the day, and this phase shift correlates strongly with retinal ganglion cell loss, suggesting that circadian disruption is a marker of disease severity. For lighting and healthcare design, this underscores the importance of maintaining robust light-dark cycles to support circadian integrity, which may be relevant to IOP regulation and glaucoma management.
Key Findings
- IOP rhythm in advanced POAG peaked during the night, opposite to the daytime peak in stable POAG (p < 0.0001)
- 24-hour IOP phase correlated significantly with retinal ganglion cell loss (p < 0.0001)
- Internal phase shift between IOP rhythm and body temperature rhythm increased progressively with POAG progression (p < 0.001)
- Study included 115 participants: 65 stable POAG and 50 advanced POAG, with IOP and temperature measured over a 72-hour span
- ACE I/D gene polymorphism identified as a candidate genetic factor influencing circadian IOP variability in advanced glaucoma
