“…35 Other recent population-based studies have also used rebound tonometry, and we anticipate others will opt for this method in the future. 37,38 This study has limitations. Although household visits were made to increase the response rate, the proportion of eligible people captured was about 72.5%, and nonparticipation was greater among the oldest age group.…”

“…For example, GAT measurements have been shown to be preferentially recorded as even as opposed to odd numbers, and the results of the first eye likely influences the measurement of the second eye, probably because of the belief that IOP should be symmetric between the two eyes 35 . Other recent population-based studies have also used rebound tonometry, and we anticipate others will opt for this method in the future 37,38 …”

Précis: Intraocular pressure decreased with age in a population-based study in Nepal, from a mean of 14.1 mm Hg among 60–64-year-olds to 13.0 mm Hg among ≥80-year-olds. Purpose: Few studies have assessed the distribution of intraocular pressure (IOP) from the Indian subcontinent, despite its large population and high burden of glaucoma. The objective of this study was to assess the distribution of IOP measurements from adults living in a lowland region of Nepal. Methods: In a population-based cross-sectional study, all individuals aged 60 years and older from an area of lowland Nepal were invited for IOP assessment with a rebound tonometer. Results: Of 160 communities (28,672 people aged ≥60 y) enrolled, 79 (13,808 people aged ≥60 y) were randomly selected for IOP testing. Of those eligible, 10,017 (72.5%) individuals underwent tonometry. Mean IOP decreased monotonically over 5-year age groups, from 14.1 mm Hg (SD 3.6) among the 60–64-year-olds to 13.0 mm Hg (SD 4.2) among those ≥80 years. The 97.5th percentile IOP measurement was 21.0 mm Hg for all age groups. In adjusted analyses, younger age, self-reported diabetes, and higher population density were each associated with higher IOP and self-reported cataract surgery was associated with lower IOP. Conclusions: Mean IOP was lower among older individuals in Nepal, consistent with many studies from East Asia and in contrast to many studies from western populations. These results suggest that ethnic background might be a consideration when diagnosing ocular hypertension.

“…that age was not a significant predictor of IOP. 31 Results from human studies are also variable, with some reports indicating higher IOP, 32 lowerIOP, 33,34 or no IOP association 35,36 in older individuals relative to younger individuals. Finally, we found a positive association between IOP and weight, which is in agreement with expectations and previous research.…”

Purpose: Rhesus macaques (Macaca mulatta) are the premier nonhuman primate model for studying human health and disease. We aimed to investigate if age was associated with ocular features of clinical relevance in a large cohort of free-ranging rhesus macaques from Cayo Santiago, Puerto Rico. Methods: We evaluated 120 rhesus macaques (73 males, 47 females) aged from 0 to 29 years old (mean±SD: 12.6/6.4) from September to December, 2021. The ophthalmic evaluation included IOP assessment, corneal pachymetry, anterior segment biomicroscopy, A-Scan biometry, automated refraction, and fundus photography after pupil dilation. The effects of age on the outcome variables were investigated through multilevel mixed-effects models adjusted for sex and weight. Results: On average, IOP, pachymetry, axial length, and automated refraction spherical equivalent were 15.47±2.47 mmHg, 474.43±32.21 micras, 19.49±1.24 mm, and 0.30±1.70 D, respectively. Age was significantly associated with pachymetry (Coef.= -1.20; 95%CI: -2.27 to -0.14; p=0.026), axial length (Coef.= 0.03; 95%CI: 0.01 to 0.05; p=0.002), and spherical equivalent (Coef.= -0.12; 95%CI: -0.22 to -0.02; p=0.015). No association was detected between age and IOP. The prevalence of cataracts in either eye was 10.83% (95% CI: 6.34 - 17.89%) and was significantly associated with age (OR= 1.20; 95%CI: 1.06 - 1.36; p=0.004). Retinal drusen in either eye was observed in 15.00% (95% CI: 9.60 - 22.68%) of the animals, which was also significantly associated with age (OR=1.14; 95%CI: 1.02 - 1.27; p=0.020). Conclusions: Rhesus macaques exhibit age-related ocular associations similar to those observed in human aging, including decreased corneal thickness, increased axial length, myopic shift, and higher occurrence of cataract and retinal drusen.
