Abstract

Introduction: Intraocular pressure (IOP) is the pressure sustained by the aqueous humor within the eyeball [1]. IOP is of inherent physiologic importance in maintaining the structure and function of the eye [2]. Intraocular pressure is the easily modifiable risk factor in the treatment of glaucoma and its value can be influenced by the central corneal thickness. Identifying the pattern of IOP and CCT in a population with respect to age and gender is important as these vary in different populations.

Methods: A population-based descriptive cross sectional study conducted among adult Nigerians aged 18 years and older. Multi-staged random sampling technique was used to select eligible subjects for the study. All participants had optical pachymetry, applanation tonometry, fundus examination and visual acuity measurement done.

Results: Age and sex distribution of study population: A total of four hundred and eighty subjects participated in the study. There were 212 males (44.2%) and 268 females (55.8%) giving a male to female ratio of 1: 1.3. The mean age of the study population was 43.0±14.2 years. Age ranged from 18 to 91 years.
