A Study Comparing Two Optical Coherence Tomography Devices in People With Ocular Tumors

The purpose of this study is to compare two devices used for optical coherence tomography (OCT). OCT is a noninvasive imaging (scanning) method that uses reflected light to create pictures of the back of the eye, and doctors can use OCT to detect and monitor different types of cancer

Superb Microvascular Intraocular Tumor Imaging Study (SMITIS)

The diagnosis and monitoring of intraocular tumors are based on multimodal imaging in addition to the clinical examination (ultra-widefield retinal imaging, echography, angiography). Nevertheless, it may be difficult in cases of retinal hemorrhage, small tumor size or atypical presentation. The study of microvascular flow (Superb Microvascular Imaging, SMI) of intraocular tumors could improve the confidence of differential diagnosis when evaluating these suspicious lesions, or even determine whether a lesion is benign or malignant by describing the vascularization of the lesion. The investigators propose to study the microvascular flow patterns of intraocular tumors prior to proton therapy.

Intraoperative OCT Guidance of Intraocular Surgery II

The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical visualization.
