β1 (eg metoprolol is a β1 blocker) & β2 (eg albuterol is a β2 agonist) receptors work by Gs (AC -> cAMP -> PKA), while α1 (eg terazosin is an α1 blocker) work by Gq (PLC -> PIP2, IP3 -> Ca2+, DAG -> PKC. Besides the heart, β1 receptors are used for aqueous humor production.

Gonioscopic examination of a traumatic angle recession shows widening of the ciliary body band.  Separation between the longitudinal and circular muscle of the ciliary body (commonly caused by blunt injury to the eye)  Incidence of intraocular pressure elevation appears to be directly related to the extent of angle involvement (may require at least 180 or 270 degree involvement)  Clinical features:  Symptoms:  May be asymptomatic  In the acute phase following injury, early onset glaucoma may…
