The second patient, a 66-year-old white woman with pseudophakic bullous keratopathy, multiple failed penetrating keratoplasties, and secondary glaucoma, underwent concurrent Boston KPro type 1 and pars plana tube-shunt placement. The iris was initially observed at the inferior optic margin 3 months postoperatively, but it did not cause visual obstruction, with BCVA 20/50. However, by 4½ years postoperatively, the patient's BCVA declined to 20/800, likely due to glaucoma progression and progressive central iris migration into the visual axis. The iris obstructed the inferior optical axis by 0.98 mm as measured clinically at the slitlamp and by 0.70 mm of iris–Boston KPro touch radially at the 225° meridian and 0.67 mm at the 270° meridian with 0.28-mm thickness as measured by AS-OCT (Figure 2A-C). A trial of cycloplegics to relieve the iris obstruction was unsuccessful. The patient underwent argon laser iridoplasty for visually significant optic obstruction, and less than 0.5 mm of iris remained in the visual axis clinically by slitlamp measurement and 0.29 mm of iris–Boston KPro touch remained at the 225° meridian by AS-OCT after the procedure (Figure 2B-D). The woman noted a significant improvement of both visual acuity and visual field, with measured BCVA of 20/70 and expansion of the inferior field on testing with Humphrey visual field 24-2 threshold protocol with size V stimulus (Figure 2E and F). The superior visual field was restricted secondary to upper eyelid ptosis and, at the time of writing, the patient was scheduled to receive blepharoplasty, which will likely further improve the peripheral visual field. However, although Humphrey visual field examinations were repeated with similar results, interpretation of the visual fields is limited secondary to fixation losses of 14/25 and 11/21 before and after laser use, respectively. The anterior chamber depth and angle remained stable.
