Stromal Curvature, Power and Corneal-Stromal Curvature Ratios From a Hybrid AS-OCT in Eyes With Keratoconus. [PDF]
Clin Exp OphthalmolABSTRACT Background To characterise stromal curvature and curvature ratios in keratoconus (KCN) using anterior segment OCT, and to evaluate the implications of using single‐, two‐, and three‐surface refractive models for corneal power estimation in ectatic eyes. Methods Retrospective observational study.

Optical coherence tomographic findings in optic nerve hypoplasia
Indian Journal of Ophthalmology, 2013 We investigated a case of unilateral optic nerve hypoplasia using spectral domain optical coherence tomography (SDOCT). Optical coherence tomography was done on both eyes using 5-line Raster scan for the fovea to analyze the retinal nerve fiber layer ...

Role of Optical Coherence Tomography on Corneal Surface Laser Ablation [PDF]
, 2012 This paper focuses on reviewing the roles of optical coherence tomography (OCT) on corneal surface laser ablation procedures. OCT is an optical imaging modality that uses low-coherence interferometry to provide noninvasive cross-sectional imaging of ...
