Topical netarsudil for treatment of glaucoma with elevated episcleral venous pressure: A pilot investigation in sturge-weber syndrome

Abstract

Purpose

Topical netarsudil 0.02% may reduce intraocular pressure (IOP) by decreasing episcleral venous pressure (EVP), which carries theoretical utility for glaucoma associated with elevated EVP. A role for netarsudil in patients with elevated EVP is evaluated in a pilot investigation using a cohort of individuals with Sturge-Weber syndrome (SWS).

Methods

Retrospective study of patients with SWS and glaucoma who were treated with netarsudil. Five patients (six eyes) were identified. Data collected included demographics, visual acuity, IOP, glaucoma medical and surgical treatments, and adverse effects of netarsudil.

Results

Mean age was 13.6  ±  8.5 years. EVP elevation was presumed based on clinical stigmata and/or historical features. Mean number of baseline glaucoma medications was 3.3  ±  1.2. There was a significant reduction in the IOP at netarsudil initiation (mean 26.2  ±  4.5 mmHg) to 1 month of netarsudil therapy (mean 20.2  ±  3.8 mmHg, p  =  0.0283) and latest IOP on netarsudil (mean 17.6  ±  1.4 mmHg, p  =  0.0034). Mean duration of netarsudil therapy was 18.7  ±  11.8 months. Three patients required additional glaucoma procedures; one patient required an additional glaucoma medication. Three eyes (50%) developed conjunctival hyperemia. One patient discontinued netarsudil at 29 months, to reduce drop burden.

Conclusions

Netarsudil can effectively reduce IOP in patients with SWS, even when used as a fourth or fifth glaucoma medication. A possible role for netarsudil in the management of patients with elevated EVP is suggested pending further future investigations.
