Sectoral Changes in Neuroretinal Rim Pallor Across Refractive Error.

ABSTRACT:

Purpose

To investigate the association between spherical equivalent refraction (SER) and pallor in different neuroretinal rim (NRR) sectors.

Design

Population-based cross-sectional study.

Participants

Normal eyes of 24 057 healthy participants aged 40 to 70 years from the UK Biobank.

Methods

Pallor in different NRR sectors was quantitatively derived from color fundus photographs using automated software. We first examined the association between SER and pallor in each NRR sector-controlling for age, sex, ethnicity (White vs. non-White), intraocular pressure, and mean blood pressure. We then incorporated disc-fovea distance (the shortest distance from the center of the disc to the fovea) and temporal arterial/venous concavity (extent to which the temporal artery
