Background: We report the long-term outcome of uveitis associated with cancer immunotherapy (CIT). Methods: This retrospective review included serial patients with CIT-associated uveitis treated using various regimen. Results: Eight patients treated with rituximab (anti-CD20), nivolumab (anti-PD-1), ipilimumab (anti-CTLA-4), vemurafenib and dabrafenib (anti-BRAF), trametinib (anti-MEK) and ibritunib showed uveitis with hypopion (one patient), macular edema (five patients) and choroiditis (two patients). Various regimens of corticosteroid therapy showed a favorable ophthalmological outcome, whether the CIT was continuing or suspended. Conclusion: Local corticosteroid injections in combination with CIT could be suggested as a first-line treatment. This could help to preserve the quality of life without threatening the vital prognosis.

This article describes the ocular phenotype associated with the identified Casitas B-lineage lymphoma (CBL) gene mutation and reviews the current literature. This work also includes the longitudinal follow-up of five unrelated cases of unexplained fundus lesions with visual loss associated with a history of hepatosplenomegaly. Wide repeated workup was made to rule out infections, inflammatory diseases, and lysosomal diseases. No variants in genes associated with retinitis pigmentosa, cone–rod dystrophy, and inherited optic neuropathy were found. Molecular analysis was made using next-generation sequencing (NGS) and whole-exome sequencing (WES). The results included two cases sharing ophthalmological signs including chronic macular edema, vascular leakage, visual field narrowing, and electroretinography alteration. Two other cases showed damage to the optic nerve head and a fifth young patient exhibited bilateral complicated vitreoretinal traction and carried a heterozygous mutation in the CBL gene associated with a mutation in the IKAROS gene. Ruxolitinib as a treatment for RASopathy did not improve eye conditions, whereas systemic lesions were resolved in one patient. Mutations in the CBL gene were found in all five cases. In conclusion, a detailed description may pave the way for the CBL mutation ocular phenotype. Genetic analysis using whole-exome sequencing could be useful in the diagnosis of unusual clinical features.
