Purpose: To estimate the proportion of racial and ethnic disparities observed in glaucoma surgical outcomes that can be eliminated by curbing differences in socioeconomic status (SES).
Design: Retrospective cohort study.
Subjects: The entire population of 2016-2018 California (CA) fee-for-service Medicare beneficiaries with a claim for incisional glaucoma surgery (trabeculectomy, tube shunt, or EX-PRESS shunt).

Increasing age and elevated intraocular pressure (IOP) are the two major risk factors for glaucoma, the most common cause of irreversible blindness worldwide. Accumulating evidence is pointing to metabolic failure predisposing to neuronal loss with advancing age and IOP injury. Many neurotransmitters are synthesized from endogenous metabolites and are essential for correct cell to cell signaling along the visual pathways.

Muscle contraction is driven by myosin motors from the thick filaments pulling on the actin-containing thin filaments of the sarcomere, and it is regulated by structural changes in both filaments. Thin filaments are activated by an increase in intracellular calcium concentration [Ca] and by myosin binding to actin. Thick filaments are activated by direct sensing of the filament load.
