Optic disc and peripapillary tumors

This review covers the tumors either originating or seen close to the optic disc in the peripapillary area. Most of the optic disc tumors are diagnosed on clinical examination. In a few atypical cases, ancillary imaging, such as optical coherence tomography, fluorescein angiography, and ultrasonography, may be required to demonstrate characteristic features. The majority of these tumors have systemic associations, and hence, a multidisciplinary approach involving ocular oncologists, neurophysicians, radiation oncologists, and medical oncologists is the need of the hour. The treatment of optic disc tumor is challenging due to its proximity to critical areas such as optic nerve and macula, which could be a limiting step when compared to conventional treatments such as laser photocoagulation and surgical excision.
