A Case of Honeycomb Corneal Epitheliopathy Induced by Netarsudil 0.02% Ophthalmic Solution

초록

Purpose To document the clinical presentation and progression of corneal epitheliopathy, with its characteristic honeycomb pattern, associated with topical Netarsudil 0.02% use in a patient with neovascular glaucoma (NVG).<br /> Case summary A 60-year-old man presented with left ocular pain and headache, with an intraocular pressure (IOP) of 37 mmHg in the left eye. After a diagnosis of NVG, he was treated with intravitreal anti-VEGF injection and topical anti-glaucoma medications. On the fifth day after adding Netarsudil, central corneal epithelial edema was noted. By day 7, a diffuse epithelial haze with a honeycomb-like appearance had developed. IOP measured by rebound tonometry was 47 mmHg, while Goldmann applanation tonometry underestimated the value at 22 mmHg, likely due to irregularities at the corneal surface. Netarsudil was discontinued and replaced with latanoprost, leading to rapid improvement. Due to persistent elevated IOP, Ahmed glaucoma valve implantation was performed, resulting in stable IOP and complete normalization of the corneal surface.<br /> Conclusions While Netarsudil is effective for lowering IOP, it can infrequently lead to reversible corneal epithelial edema characterized by a honeycomb-like pattern, particularly in patients with compromised corneal integrity. Therefore, close monitoring of corneal status is necessary when using Netarsudil in high-risk patients.
