Aqueous Outflow Facility & Intraocular Pressure Equilibrium

Intraocular pressure is not fixed — it is the steady-state output of a fluid circuit: aqueous humor secreted continuously by the ciliary body, drained through the resistance of the trabecular meshwork into the episcleral veins, with a smaller pressure-independent bleed through the uveoscleral pathway. This simulator renders that circuit as a real particle system inside a 3D eye cross-section and computes live IOP from the Goldmann equation, IOP = (F − F_u)/C + P_v, as you adjust production rate, trabecular outflow facility, episcleral venous pressure and uveoscleral outflow — including preset glaucoma and medication scenarios that show why lowering meshwork resistance (not just cutting production) is the target of most first-line therapy.
