OCT used as a tool for pupilloplasty evaluation

OCT is based on the principle of Michelson interferometry. It uses a near infrared wavelength source for visualization of ocular structures. There are two different types of OCT systems based on type of processing: time domain and spectral domain. SD-OCT provides faster acquisition and higher resolution as compared with TD-OCT. It takes 26,000 A-scans per second with a rate of 256 to 1,024 frames per second. The depth resolution in tissue is 5 µm, and the transverse resolution is 15 µm. There have been various indications for SD-OCT in ophthalmology. (Read more...)
