Abstract

To describe a case of netarsudil-associated honeycomb keratopathy in a patient with iridocorneal endothelial (ICE) syndrome.
A 43-year-old male with a history of Cogan-Reese variant ICE syndrome presented with ocular irritation, foreign body sensation, blurred vision, photosensitivity, and discharge in the right eye 2 weeks after initiating topical netarsudil 0.02% for secondary angle-closure glaucoma. Slit lamp exam and anterior segment optical coherence tomography demonstrated diffuse reticular epithelial cysts, consistent with netarsudil-induced honeycomb keratopathy. Three weeks after netarsudil cessation, slit lamp exam showed complete resolution of corneal edema.
Endothelial cell dysfunction in ICE syndrome may be a risk factor for patients to develop reversible netarsudil-induced honeycomb keratopathy. Ophthalmologists should exercise caution when prescribing netarsudil for glaucoma management in patients with pre-existing corneal pathologies, including those with ICE syndrome.
