The Influence of Tomographic Corneal Characteristics on Epithelial Thickness Profile.

Purpose To understand the influence of tomographic corneal characteristics on the epithelium of normal eyes. Methods We scanned a total of 98 eyes of 98 individuals using anterior segment tomography and a spectral-domain optical coherence tomography (OCT) epithelial mapping tool. Only eyes with no previous pathology were included, with a refractive range of +5 diopters (D) to -6 D, intraocular pressure of < 22 mmHg, and no evidence of dry eye (Schirmer's test 2 value > 5 mm).

Wide Stromal Mapping Using an Anterior Segment Optical Coherence Tomography.

Purpose: To quantify and assess the reproducibility of the corneal stromal thickness profiles captured by the SD-OCT. Secondly, we correlated the zonal thicknesses to the age, gender and axial length.

Methods: We included 227 normal eyes of 227 patients with a maximum hypermetropia of +5 and myopia of -6 diopters (D).

Assessing reproducibility and the effects of demographic variables on the normal macular layers using the Spectralis SD-OCT.

Purpose: To quantify and view the possible influence of demographic variables on normal macular layers. Additionally, we wanted to assess the reproducibility using the Spectralis SD-OCT.

Methods: A Spectralis SD-OCT machine using a commercially available algorithm was used to scan 242 healthy subjects in an outpatient setting.
