What is the difference between selective and non-selective beta blockers for glaucoma treatment?

What is the difference between selective and non-selective beta blockers for glaucoma treatment?

Beta 1 receptors are in the heart and blocking them can cause the heart to slow down causing tiredness, irregular heart beat and shortness of breath....One of the drawbacks of timolol. Selective beta blockers such as betoptic (betaxolol) are supposed to have less of an effect of this type but are best avoided if a patient is sensitive to beta blockers. ...Read more

Since bystoilc is selective beta blocker(works on the heart only), can it still lower ocular pressure in glaucoma or does non selective bb is better ?

Since bystoilc is selective beta blocker(works on the heart only), can it still  lower ocular pressure in glaucoma or does non selective bb is better ?

Yes: Systemic beta blockers(bb) can lower iop, but not as effectively as when a topical ophthalmic preparation is used. Selective vs non- selective bbs very in their potency at blocking beta receptors in the eye & heart. Non-selective bbs block both types of receptors(b1 & b2) and lower iop more than selective type( b1). The later type is thought to be a safer medication with less pulmonary side effect. ...Read more
