Ocular tumors

Abstract

Advances in ophthalmic imaging improved diagnosis and management of ocular tumors. Optical coherence tomography (OCT) is a powerful imaging technique that provides cross-sectional imaging of the internal microstructures of biological tissues (Huang et al. 1991). Spectral domain OCT (SD-OCT) has replaced traditional time domain OCT providing high-resolution, high-sensitivity, and high-speed imaging (up to 40,000 scans per second). Such implementations enable noninvasive and noncontact visualization and measurement of the microstructures of the human eye. Recently, software upgrades and new imaging techniques have improved the ability to better evaluate intraocular tumors by allowing longer scan lengths, enhanced depth imaging (EDI), and three-dimensional reconstruction. In ocular oncology, OCT provides tools for diagnosis, treatment planning, and monitoring response.
