PURPOSEWe report a case of posterior globe collapse of an eye after initial recovery from uncomplicated cataract surgery in a patient with high myopia and discuss the course of management involving recognition and emergent air injection with globe reformation. CASE REPORTA 64-year-old functionally monocular male with a history of high myopia presented for follow-up after uncomplicated cataract surgery. Uncorrected distance visual acuity (UCDVA) at postoperative day 1 was 20/150 with an intraocular pressure (IOP) of 19 mm Hg. At the week 1 visit, UCDVA had decreased to 20/200 with an IOP at 9 mm Hg. After preliminary exam, the keratome site suture was removed, after which the patient reported vision changes. A dilated fundus exam was performed revealing posterior scleral wall collapse. A clinical diagnosis of hypotony was made and a pars plana injection of 1 mL air was performed. This resulted in immediate subjective improvement of vision. Exam the next day revealed UCDVA 20/50 with pinhole improvement to 20/30 and IOP 15 mm Hg. CONCLUSIONThis case demonstrates postoperative hypotony in a patient with pathologic myopia, following cataract surgery. Pathologically myopic eyes may have greater propensity to collapse in the setting of reduced IOP.
