The block in flow of  aqueous from  the posterior to the anterior chamber will lead to a condition known as Iris bombe. In this condition,  pressure in the posterior chamber rises, resulting in anterior bowing of the peripheral iris and obstruction of the trabecular meshwork.
The blockage of aqueous flow between the posterior and anterior chambers results in Iris bombe. In this scenario, increased pressure within the posterior chamber causes the peripheral iris to bulge forward and impede the trabecular meshwork.
