Abstract:From 1990s, optical coherence tomography(OCT)can diagnose more diseases as early as possible. It's visible, quantified, noninvasive, painless, high resolution and so on. In recent years, refractive errors have an increasing incidence and the age of onset becomes younger. More and more researchers focus on the problem using technology in refractive error study. It can find small changes in retinal and choroidal thickness early. If we take immediate actions, it may build a foundation for further study. This article summarizes the application of optical coherence tomography in refractive error.
