PURPOSE: Immunotherapy has become an important addition to oncology treatment plans in recent years. As these therapies become more widely employed, many unique side effects have been reported. In ophthalmology the most well-documented side effects of immune checkpoint inhibitors (ICI) include uveitis, macular edema and dry eye syndrome. This manuscript describes a rare case of bilateral choroidal effusions and secondary angle narrowing in the setting of systemic capillary leak syndrome (SCLS) from an HLA-directed vaccine and an ICI, pembrolizumab, for the treatment of stage IV squamous cell carcinoma (SCC) of the lung. OBSERVATIONS: A 67-year-old male with a history of stage IV SCC of the lung status-post pneumonectomy presented to the emergency department due to functional decline, anasarca, and dyspnea after receiving an HLA-directed vaccine in combination with pembrolizumab. Extensive workup revealed that his symptoms were secondary to SCLS. Ophthalmology was consulted due bilateral choroidal detachments seen on magnetic resonance imaging. B-scan ultrasound and ultrasound biomicroscopy revealed large, non-appositional choroidal effusions with anterior rotation of the ciliary body. Given minimal response to oral steroid therapy, sub-Tenon's triamcinolone acetonide, atropine, and intraocular pressure-lowering eyedrops were initiated with a good response. CONCLUSIONS AND IMPORTANCE: Choroidal effusions and secondary angle closure can be rare complications of SCLS in the setting of ICIs. Clinicians must be aware of the potentials side effects of ICI therapy, as these medications become more commonly used.
