Purpose:
To report a case of bilateral anterior uveitis undergoing atezolizumab treatment for advanced non-small cell lung cancer (NSCLC).
Observations:
A 64-year-old man was receiving atezolizumab for metastatic programmed cell death ligand 1 (PD-L1) positive NSCLC as first line therapy. Three weeks after first atezolizumab administration, he complained of blurry vision in both eyes and was referred to our clinic. At initial presentation, slit lamp examination revealed bilateral Descemet membrane folds, fine keratic precipitates, and anterior chamber cells 2+. Dilated fundus examination showed no abnormal findings. A complete laboratory evaluation ruled out infectious or autoimmune causes of the uveitis and he was diagnosed with uveitis caused by atezolizumab. Atezolizumab was suspended, administration of topical corticosteroid was initiated, and the anterior uveitis was resolved within one month.
Conclusion And Importance:
This is the first case report of bilateral anterior uveitis associated with atezolizumab and that PD-1 and PD-L1 inhibitors cause uveitis.
