Anterior Segment Optical Coherence Tomography Study of the Cornea and Anterior Segment in Adult Ethnic South Asian Indian Eyes

Abstract

The authors have described useful baseline anterior segment parameters from this population-based study of ethnic South Indian adults. These data may be useful for corneal and anterior segment procedures such as endothelial keratoplasty and anterior chamber intraocular lens insertion.

En face optical coherence tomography angiography for corneal neovascularisation

“…The ‘en face’ mode produces C-scans that are orientated to the frontal plane and gives transverse slices of a corneal lesion and neovascularisation—which is more intuitive to untrained operators, as opposed to the traditional cross-sectional OCT ‘B-scans’ that resemble histology slides, and are more useful for studying anterior segment anatomy 26 27. The coronal reconstruction allows for an instant overview of the corneal pathology and changes to the length, calibre and area of corneal neovascularisation, which was previously not possible with B-scan OCT views 28.…”

Imaging in myopia: potential biomarkers, current challenges and future developments

“…However, many of these reported associations have been inconsistent, as they have been confounded by varying patient selection, variability in definitions of myopia and the use of different imaging techniques 59. Although most of the refractive error associated with myopia comes from the axial length, it is increasingly recognised that changes of the anterior segment in high myopia lead to significant optical and higher order aberrations 60.…”

Optical Coherence Tomography Angiography for Anterior Segment Vasculature Imaging

“…1 It also has been established as a useful tool in providing rapid, noncontact evaluation of the cornea and anterior segment. 2,3 Further technological developments also have increased the imaging capabilities of OCT in terms of speed, image resolution, and, more recently, evaluation of vascular flow. 4 These new OCT imaging techniques have been described for noninvasive evaluation of vessels within the retina and optic disc.…”
