Case Study by Kyle A. Kirkland, DO 1 , Sunali Goyal, MD 1 Abstract Purpose: To describe of retinal pigment epithelium detachment (PED) and keratoconjunctivitis sicca (KCS) in a patient treated with nivolumab, an anti-programmed death-1 inhibitor (PD-1) antibody. Methods: Case report of a patient referred by oncology for severe eye irritation and blurry vision while undergoing nivolumab therapy for metastatic cutaneous melanoma. Conclusion: This is the first described case of PED in a patient on nivolumab therapy. Although KCS is readily reported in the literature, aggressive and early treatment can completely resolve ocular surface disease. Drugs in the anti-PD-1 family require extremely aggressive treatment for ocular surface disease, and we suggest screening for potential retinal involvement. Introduction Retinal pigment epithelium detachment (PED) is the separation of the retinal pigment epithelium (RPE) from Bruch’s membrane. Pigment epithelial detachment is a prominent feature in retinal diseases such as age-related macular degeneration (AMD). 1 Here we describe a case with an apparent association between nivolumab, a treatment option for metastatic melanoma, and PED. Nivolumab is an anti-programmed cell death protein-1 (anti-PD-1) monoclonal antibody that inhibits T-cell check points that normally allow tumor cells to evade the host’s immunity. 2-4 Several published cases have reported the association of ocular surface disease (OSD) with use of nivolumab. 2-6 Herein, we present a case of PED associated with nivolumab for metastatic melanoma. Case A 59-year-old male with metastatic cutaneous melanoma on treatment with nivolumab was referred to the ophthalmology clinic for bilateral red, painful eyes for about one month with noticeably decreased vision over two weeks. At the time of referral, the patient was undergoing his tenth cycle of nivolumab therapy. He denied any history of dry eye disease. On initial evaluation, the patient had best corrected visual acuity of 20/200 in both eyes. Ocular examination revealed dense punctate epithelial erosions with epithelial edema, diffuse conjunctival staining, and severe papillary reaction in both eyes. Dilated fundus examination revealed a dome-shaped elevation in the right macula. High-definition ocular coherence tomography (HD-OCT) was then performed, which revealed right perifoveal PED. (Figures A-D) The patient was started on cyclosporine 0.05% with preservative-free-artificial tears every two hours while awake and lubricating ointment three times daily for severe keratitis. The PED was managed with observation. Subsequent visits at one-month and three-month follow-up showed 1 Department of Ophthalmology, University of Arkansas for Medical Sciences, Little Rock, Ark.

Due to persistent epitheliopathy, autologous serum tears were initiated for OSD and continued observation for the PED was again elected. Three months of serum tears resulted in tremendous improvement in signs and symptoms and the patient’s uncorrected visual acuity increased to 20/25 OU. Meanwhile, after his twelfth round of nivolumab, oncology recommended stopping therapy due to systemic adverse effects and opted for serial imaging and dermatologic exams. At his next follow-up appointment of six months, the patient maintained stable vision with resolution of all signs and symptoms of ocular surface disease. Ocular coherence tomography of the macula showed nearly 50% reduction in PED in size after stopping nivolumab. 282 • The Journal of the Arkansas Medical Society www.ArkMed.org
