Crystalline keratopathy following long-term netarsudil therapy

Abstract

Purpose: This case report highlights a possible association between netarsudil use and crystalline keratopathy. Observations: Presented here is the case of a 72-year-old woman with primary open-angle glaucoma (POAG) who developed corneal crystalline keratopathy after taking netarsudil for 24 months. The patient's medical history was significant for dry eye syndrome, bilateral ptosis with surgical repair, and atopy (including asthma and various ocular and systemic allergies). The patient had previously undergone surgical repair for bilateral ptosis as well. During the interval between two routine visits, this patient experienced worsening vision with associated eye irritation. Further examination revealed crystal deposits on the anterior corneal surface in the left eye, the only eye undergoing netarsudil treatment. Conclusions and importance: Long-term netarsudil use may be associated with crystalline keratopathy in the anterior stroma, with the potential to cause sight-threatening vision loss if located in the visual axis.
