Key takeaways:
- Glaucoma may be a result of two pressures: IOP and intracranial pressure.
- When one pressure is high and the other is low, it results in ganglion cell proptosis, leading to glaucoma.
KOLOA, Hawaii — Intracranial pressure may be just as critical of a factor in the progression of glaucoma as IOP, according to a speaker here at Hawaiian Eye 2025.
“We spend a lot of time arguing about the facts, but not trying to discover the truth,” John P. Berdahl, MD, said in a presentation that earned him Speaker of the Day. “The common belief is that glaucoma is a one-pressure disease … I would submit that the more likely truth is that glaucoma is a two-pressure disease: A balance between intraocular pressure and intracranial pressure, or [cerebrospinal fluid (CSF) pressure], across the optic nerve head.”….
