Ocular side effects of checkpoint inhibitors

The incidence and impact of ocular side effects in patients treated with checkpoint inhibitors are not clearly defined. We reviewed prospective phase III clinical trials of checkpoint inhibitors applied in lung cancer, renal cell cancer, and melanoma. Case reports of the occurrence of ocular toxicities in patients receiving immune checkpoint inhibitors were also included. Of the 35 articles corresponding to phase III clinical trials with checkpoint inhibitors, ocular toxicity was described in four. Forty-six clinical cases of ocular toxicity after therapy with checkpoint inhibitors have been reported. The most frequently described ocular toxicities are uveitis, inflammatory orbital disease, and alterations of the ocular surface. Ocular toxicity is underestimated in checkpoint inhibitors clinical trials. Early ophthalmic examination and treatment with corticosteroids may improve the visual prognosis in these patients.

Ocular toxicities in patients treated with checkpoint inhibitors are not clearly defined and are often underestimated in clinical trials. Early ophthalmic examination and treatment with corticosteroids may improve the visual prognosis for these patients.
