This study aimed to assess the influence of age on intraocular pressure (IOP) in a general population. The Blue Mountains eye study assessed 3654 residents aged 49+ years during 1992-1994. IOP was measured using Goldmann applanation tonometry. Subjects with glaucoma, those currently on glaucoma medications, and those with a history of cataract surgery were excluded. IOP was reliably measured in 3260 subjects. Mean IOP was 16.0 mmHg with no significant difference found between males and females (p < 0.89). In univariate analyses, age was positively associated with IOP (p < 0.05). Systolic blood pressure (SBP) was strongly positively associated with IOP (p < 0.001). After adjusting for SBP, there was a trend for IOP to decrease with increasing age (p < 0.051). After further adjusting for other potential confounders (diabetes, glaucoma family history and myopia), age was no longer significantly associated with IOP (p < 0.29). In summary, no evidence was found of an independent age affect on IOP.
