Reproducibility-repeatability of choroidal thickness calculation using optical coherence tomography.

Purpose: To evaluate the repeatability and reproducibility of subfoveal choroidal thickness (CT) calculations performed manually using optical coherence tomography (OCT).

Methods: The CT was imaged in vivo at each of two visits on 11 healthy volunteers (mean age, 35.72 ± 13.

Effects of migration on food consumption patterns in a sample of Indian factory workers and their families.

Objectives: To study the impact of migration on food consumption among Indian factory workers and their siblings and spouses.

Design: A cross-sectional study was conducted to assess diet using an interviewer-administered semi-quantitative FFQ from which intake of 184 commonly consumed food items was obtained.

Settings: Participants recruited from factory sites in Bangalore, Lucknow, Nagpur and Hyderabad.

Objective measurement of intraocular forward light scatter using Hartmann-Shack spot patterns from clinical aberrometers. Model-eye and human-eye study.

Purpose: To apply software-based image-analysis tools to objectively determine intraocular scatter determined from clinically derived Hartmann-Shack patterns.

Setting: Aston Academy of Life Sciences, Aston University, Birmingham, United Kingdom, and Department of Optics, University of Valencia, Valencia, Spain.

Methods: Purpose-designed image-analysis software was used to quantify scatter from centroid patterns obtained using a clinical Hartmann-Shack analyzer (WASCA, Zeiss/Meditec).
