Overview
Optical coherence tomography provides micrometer scale cross sectional images. It is widely used in ophthalmology and increasingly in other specialties. OCT reveals microstructure and supports quantitative analysis.
Ophthalmic Applications
Retinal OCT assesses macular edema and degeneration. Anterior segment OCT evaluates corneal and angle anatomy. OCT angiography visualizes retinal and choroidal vasculature without dye.
Non Ophthalmic Uses
OCT is explored for dermatology cardiology and gastroenterology applications. It can image mucosal and vascular microstructure in research settings. Translation to clinical practice requires validation and workflow integration.
Future Directions
Higher speed and resolution systems expand OCT capabilities. Multimodal imaging combines OCT with fluorescence and other contrasts. Quantitative biomarkers support diagnosis and monitoring.
