Purpose: To describe the patient characteristics and the clinical course of an unusual reticular pattern of bullous epithelial corneal edema in a series of patients treated with netarsudil.
Design: Retrospective case series.
Methods: Case series at a single academic center where treatment with netarsudil produced a particular pattern of bullous epithelial corneal edema.
Results: Six episodes of reticular bullous epithelial corneal edema were identified in 5 eyes of 5 patients treated with netarsudil. A total of 4 of 5 patients had a history of corneal edema in the affected eye, and the fifth patient had risk factors for corneal edema including a history of anterior uveitis and an anterior chamber glaucoma drainage device. In 4 of 6 episodes, corneal edema was present, typically in the corneal stroma at the time of netarsudil initiation. In 5 of 6 cases, visual acuity worsened with onset of bullous epithelial edema, and in all cases, visual acuity stabilized or improved following discontinuation of netarsudil. In all cases, the reticular bullous epithelial edema improved or resolved after discontinuation of netarsudil.
Conclusions: The patient characteristics and natural history of a particular pattern of reticular bullous epithelial edema in a series of patients treated with netarsudil once daily is reported. Most patients had a history of corneal edema or predisposing risk factors for corneal edema. All patients demonstrated improvement in bullous epithelial edema after netarsudil discontinuation. Visual acuity improved in most patients within weeks after discontinuation of netarsudil, although 2 patients also underwent surgical interventions that might have contributed to improved visual acuity.
