Aqueous humor dynamics and the iris
Mark HHMedical Hypotheses 2003; 60: 305-308
Solutes concentration in the aqueous humor of the eye is highest near the ciliary processes in the posterior chamber (PC)and lowest near the trabecular meshwork in the anterior chamber (AC). The high osmotic gradient across the semipermeable iris causes it easily to move forward at this location and occasionally occlude the iridocorneal angle. Vector analysis of the forces generated by miosis helps explain on osmotic grounds why it reduces the intraocular pressure while, at the same time, the analysis elucidates the reason for the higher frequency of angle closure glaucoma when the anterior chamber is shallow.
