Optical coherence tomography an emerging technology
Many ophthalmologists are aware of the uses of optical coherence tomography (OCT)1 in diagnosing glaucoma and retinal pathologies such as macular hole and cystoid macular edema. However, anterior segment OCT imaging2 is still rarely used because of lack of dedicated commercial instrumentation. Maldonado et al. have shown that the commercial OCT retinal scanner (Zeiss Humphrey Systems, Dublin, CA) can be used to image corneal anatomy after LASIK.3 This has sparked an interest in developing dedicated anterior segment OCT systems.
