Glaucoma following penetrating keratoplasty (PKP) remains the leading cause of blindness following PKP. Patients with post-PKP glaucoma can be managed medically and surgically. Evidence studying glaucoma surgical techniques following PKP is limited, but suggests the possibility for high-risk complications, including graft failure. Minimally invasive glaucoma surgeries offer an alternative. We report the first case of post-PKP glaucoma managed with gonioscopy-assisted transluminal trabeculotomy (GATT). The patient was a 33-year-old man with a history of keratoconus who underwent PKP in his right eye. On presentation, his visual acuity was 20/60 and intraocular pressure was 48 mm Hg OD. He underwent GATT and cataract phacoemulsification. Following 22 months of follow-up, the patient's visual acuity was 20/30 and intraocular pressure 13 mm Hg, off all glaucoma medications. This case demonstrates GATT may be a good surgical option for post-PKP glaucoma, given the ability to perform future incisional surgery and avoidance of high-risk complications associated with traditional glaucoma surgeries.
