Abstract
Routine phaco-emulsification in an eye with Ahmed glaucoma valve(AGV) in place can lead to blockage of the valve by nucleus material or viscoelastic or dye. This can lead to post operative intra ocular pressure(IOP) peaks which can be disastrous for a glaucoma patient. After years of successful IOP control with valve, patient experiences raised IOP post cataract surgery and can have deterioration in glaucoma control.We performed a technique called as “Angular rotation of Tube” in which we rotated the intraocular portion of the AGV tube with an iris hook into the angle by carefully creating an entry into anterior chamber at an acute angle to the tube. There was no blockage of the tube and the intraocular pressure post phaco emulsification remained within desired limit.
