In aqueous misdirection, the interval between diagnosis and surgical intervention is inversely proportional to the success of the surgery. Here, we report a successful outcome of pars plana vitrectomy (PPV) with irido-zonulo-hyaloidectomy 4 years after the onset of the disease. A 34-year-old female, known to have primary angle closure glaucoma, underwent trabeculectomy with mitomycin C in the right eye for uncontrolled intraocular pressure (IOP). Six weeks after the surgery, the patient presented with a shallow anterior chamber centrally and peripheral iridocorneal touch along with a patent peripheral iridectomy. Ultrasound biomicroscopy showed a shallow AC centrally with peripheral iridocorneal touch, and the ciliary body was rotated forward confirming the diagnosis of aqueous misdirection. The patient refused surgical management and was managed medically, which was unsuccessful. Four years after the diagnosis, the patient underwent PPV with irido-zonulo-hyaloidectomy because of progressive shallowing of the AC and corneal edema. One month postoperatively, visual acuity improved from 20/200 to 20/60, and the AC maintained appropriate depth. In conclusion, PPV with irido-zonulo-hyaloidectomy may result in a complete resolution of a chronic low-grade form of aqueous misdirection.
