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.
Iris bombe is a condition that occurs when the flow of aqueous fluid from the posterior to the anterior chamber is blocked. This leads to elevated pressure in the posterior chamber, which causes the peripheral iris to protrude forward and obstructs the trabecular meshwork.
