Abstract Purpose: The aim of this prospective study was to assess choroidal morphology and vasculature in healthy young Saudi adults by spectraldomain optical coherence tomography imaging with confocal scanning laser ophthalmoscopy (OCT-SLO). Methods: Eyes with the most visible choroid–sclera junction in 110 consecutive healthy subjects (mean age = 30 ± 6.20 years; range = 20–40 years; 53 women) were imaged by one examiner using an Optos OCT-SLO system. Choroidal morphologic and vascular parameters were subjectively assessed by one experienced rater.

Purpose
The aim of this study was to determine the central corneal thickness ( CCT) of healthy Saudi
children aged 7–12 years and investigate variations in CCT according to age and sex.
Patients and methods
In this prospective study, one eye was analyzed from each of 412 healthy children. The CCT
was measured using a noncontact Nidek CEM 530 specular microscope. A regression analysis
was carried out to determine the relationship between CCT and age, and an unpaired t-test

Purpose
The aim of this study was to describe the corneal endothelial morphology of healthy Saudi
children aged 7–12 years and investigate variations on the basis of age and sex.
Participants and methods
In this prospective study of 412 healthy children, one eye was examined of each child. The
endothelial cell density ( ECD), percentage coeffi cient of variation (CV), and cell hexagonality
( Hex) were determined using a noncontact Nidek CEM 530 specular microscope. An unpaired
