Transient Reticular Cystic Corneal Epithelial Edema With Topical Netarsudil: A Case Series and Review

LoBue, Stephen A; Moustafa, Giannis A; Vu, Anderson; Amin, Mira; Nguyen, Thanh; Goyal, Himani
PURPOSE:To describe cases in which netarsudil ophthalmic solution 0.02% precipitated reversible, reticular cystic epithelial edema. METHODS:A retrospective case review at the Brooklyn Veteran's Association Hospital of patients with corneal stromal edema that were treated with netarsudil and subsequently developed cystic epithelial edema. RESULTS:Four male patients with a mean age of 72 ± 8.0 years developed a reticular, honeycomb-like pattern of epithelial edema located in the interpalpebral and inferior cornea. In 3 of 4 patients, epithelial edema arose within 1 month compared with 2 months in 1 patient. New epithelial cysts did not correlate with worsening central corneal thickness and best spectacle-corrected visual acuity in every patient, which was likely due to the location of the cysts. Two of 4 patients developed increased central corneal thickness with worsening best spectacle-corrected visual acuity. In comparison, 1 patient had improvement in both parameters, whereas 1 patient had no significant change. In all cases, there was resolution of the epithelial cysts after discontinuation of netarsudil. CONCLUSIONS:Although rho-kinase inhibitors have been suggested to improve endothelial function, we have documented worsening epithelial cysts in a subset of patients with pre-existing corneal edema. These effects of netarsudil were transient and resolved after discontinuing treatment within 2 weeks in most patients. We hypothesize that the incidence of this adverse finding is more common than previously believed. Nevertheless, large-scale studies are needed to accurately report on the incidence and clinical significance of this novel finding.

Case report: The use of netarsudil to improve corneal edema after laser peripheral iridotomy and Descemet's membrane endothelial keratoplasty [Case Report]

Chen, Sabrina L; LoBue, Stephen A; Goyal, Himani
Purpose/UNASSIGNED:To report a case in which netarsudil ophthalmic solution 0.02% improved refractory corneal edema after laser peripheral iridotomy (LPI) and Descemet's membrane endothelial keratoplasty (DMEK). Observations/UNASSIGNED:A 63-year-old female presented with decreased vision due to corneal edema secondary to iatrogenic endothelial cell loss from previous YAG and argon laser peripheral iridotomy. Initial treatment with topical sodium chloride 5% solution was unsuccessful in resolving the edema. As a result, topical netarsudil was initiated off-label. Improvement in corneal thickness and visual acuity was noted, but after a few months, the left eye decompensated with worsening edema. Cataract surgery with DMEK was performed. Surgery was prolonged and intraoperative floppy iris was encountered. Post-operatively, the patient's best-corrected visual acuity (VA) fluctuated between 20/30 to 20/70 with persistent corneal edema. The central corneal thickness (CCT) ranged from 758 to 779 three months after surgery. Topical netarsudil was started again off-label for cornea edema once nightly. Over the next two months, visual acuity and CCT improved to 20/25 and 650, respectively. Stabilization of visual acuity and cornea edema has been maintained for eight months after initiation of topical netarsudil. Conclusions/UNASSIGNED:Netarsudil, a commercially available rho-kinase inhibitor, may be an effective, non-invasive adjunctive therapy for refractory corneal edema. Our case demonstrates improvement in BCVA and CCT using topical netarsudil, which has been maintained without any vision threatening side effects.
