Variation in intraocular pressure by sex, age, and geographic location in China: A nationwide study of 284,937 adults.

ABSTRACT:

Objective

To investigate the distribution characteristics of intraocular pressure (IOP) by sex, age, and geographic location in China and to build the corresponding reference intervals (RIs).

Material and methods

A cross-sectional, multi-centered, population-based study was conducted. All data were collected from participants without eye diseases who underwent ophthalmological examinations in 170 Health Screening Centers in mainland China in 2018. The non-contact tonometer was used to measure IOP. The age-, sex-, and province-specific RIs of IOP were investigated. The IOP of different age-sex groups was further explored by stratifying according to height, body mass index (BMI), blood pressure, altitude, and geographic area.

Results

During the study, a population-based
