Calcium channel blockers are associated with a lower risk of stroke and may confer neuroprotective effects on neurons undergoing apoptosis or necrosis.

The impact of calcium channel blockers on glaucoma remains a topic of debate, with some studies suggesting they may increase the risk of glaucoma and others indicating a protective effect.

In this study published in Ophthalmology Glaucoma researchers observed a potential protective association between calcium channel blocker use and visual field deterioration. But they suggested the need for further investigation.
