Abstract
- introduction A non-contrast method based on the low-coherence interferometer is the idea of optical coherence tomography (OCT). OCT’s high axial resolution shows improved delineation of the corneal surface. Systems that use spectral-domain anterior segment OCT (AS-OCT) can offer both epithelial mapping and pachymetry. It is well known that the corneal epithelium may remodel, concealing underlying stromal abnormalities. Imaging and analysis of the corneal stroma and epithelium each separately will surely lead to new discoveries that will deepen our knowledge of keratoconus. Regarding corneal remodeling in ectatic conditions, epithelium changes come first then topographic changes happen. Epithelial mapping-based modalities are trying to find epithelial based diagnostic methods for early detection of early corneal ectasia. - aim The aim of this study was to detect the role of epithelial thickness mapping in high corneal astigmatism using anterior segment OCT (MS-39). Patients and methods The study was an observational study, which included 34 eyes of patients with corneal astigmatism more than 2.00 D. Inclusion criteria: • Age from 6 to 35 years old. • Patients with high corneal astigmatism more than 2.00 Diopters. Exclusion criteria: • Patients with corneal pathology, dry eye or previous corneal surgery. • Other ocular diseases as uveitis, cataract or glaucoma. • Pregnancy and lactation.
