“…Simultaneously, our study found that when at accommodation-relaxed status, the IOPs of progressing myopes and emmetropes were not significantly different. This result was consistent with some previous studies, 11,12 but different from others. 8,10 That might be because factors influencing IOP values were very complicated (eg, central corneal thickness, corneal curvature, measuring time point, and measuring position of subjects [26][27][28][29] ) and different studies used various research methods.…”

“…9,[11][12][13] Some researchers 9,11 reported a significant association between IOP and myopia progression, whereas others 12,13 found no certain relationship between them. However, unlike the uncertainty of the relationship between static IOP values and myopia progression, IOP variations had been demonstrated to cause refraction and AL changes in many studies.…”

Purpose To investigate the changes of intraocular pressure (IOP) and anterior eye segment biometric parameters under different accommodative statuses in progressing myopes and emmetropes. Methods Forty-six progressing myopes and 40 emmetropes participated in this study. All the subjects had their IOP and anterior eye segment biometric parameters (including corneal thickness, anterior chamber depth, anterior chamber angle width, and lens thickness) measured using iCare rebound tonometer and VisanteTM anterior segmentoptical coherence tomography while accommodative stimuli of 0, 3, and 6D were presented. Results There was no significant difference in IOP between progressing myopes and emmetropes when no accommodation was induced (16.22 ± 4.11 vs 17.01 ± 3.72, respectively, t ¼ À 0.93, P40.05). However, IOP significantly increased with accommodation in progressing myopes (mean change þ 1.02±2.07 mm Hg from 0D to 6D, F ¼ 5.35, Po0.01), but remained unchanged (mean change À 0.76±3.22 mm Hg from 0D to 6D, F ¼ 1.46, P40.05) in emmetropes. Meanwhile, we found that their anterior chamber depth decreased (Po0.01), anterior chamber angle narrowed (Po0.01), and lens thickened (Po0.01) significantly with accommodation, both in progressing myopes and emmetropes. Conclusions Although no difference was detected between the IOPs of progressing myopes and emmetropes without accommodation, accommodation could induce transient IOP elevation in progressing myopes. Simultaneously, we found that their anterior chamber depth decreased, anterior chamber angle narrowed, and lens thickened with accommodation. Although emmetropes showed the similar anterior eye segment structure changes, their IOPs did not increase with accommodation. Our study indicated that IOP elevation with accommodation in progressing myopes might be related to myopia progression.

“…Shiose (1984Shiose ( , 1990 indicated that IOP is positively correlated with blood pressure (BP), obesity and other cardiac risk variables, but negatively with age. Intraocular pressure has been positively correlated with body mass index (BMI) after adjusting for age, gender and BP (Mori et al 2000), and also with increasing degrees of myopia after adjusting for age, central corneal thickness (CCT) and other related factors (Nomura et al 2004). However, these previous studies carried out in Japan measured IOP using non-contact tonometry (NCT), which has relatively low accuracy and is more likely to be affected by CCT than is Goldmann applanation tonometry (GAT) (Moseley et al 1989;Rouhiainen & Terasvirta 1990;Mackie et al 1996;Recep et al 2001;Tonnu et al 2005).…”

“…A number of studies have attempted to identify risk factors associated with higher IOP (Armaly 1967;Colton & Ederer 1980;Klein & Klein 1981;Shiose 1984Shiose , 1990David et al 1987;Shiose et al 1991;Sommer et al 1991;Klein et al 1992;Leske et al 1997;Bonomi et al 1998;Nomura et al 1999Nomura et al , 2002Nomura et al , 2004Mori et al 2000;Hashemi et al 2005;Lin et al 2005;Mitchell et al 2005;Nakano et al 2005;Xu et al 2005;Suzuki et al 2006). It is well known that IOP increases with age ) the other important risk factor for glaucoma ) among Black, White and Iranian populations (Armaly 1967;Colton & Ederer 1980;Klein & Klein 1981;David et al 1987;Klein et al 1992; Leske et al 1997;Bonomi et al 1998;Hashemi et al 2005).…”

. Purpose: To investigate the distribution of intraocular pressure (IOP) measured by Goldmann applanation tonometry (GAT) and factors correlating with IOP, with special attention to age, in a large sample of ophthalmologically normal Japanese subjects. Methods: A total of 7313 subjects (2847 male, 4466 female) were selected as a normal Japanese sample. The following exclusion criteria applied: abnormal results suggestive of any eye diseases in slit‐lamp examination, fundus photography or visual field testing using frequency‐doubling technology; corrected visual acuity < 0.7, and contact lens wear within 1 week of study examinations. All subjects were sourced from the Eye Disease Screening Service in Tajimi City, which carried out a screening programme between September 2000 and October 2001. All data, including subject age, gender, body mass index (BMI), systolic blood pressure (BP), laterality, refraction, corneal radius and IOP measured with GAT were collected from subject records. Central corneal thickness (CCT) was measured by SP‐2000P specular microscopy. Levels of IOP and correlating factors were statistically analysed. Results: Average IOP was 14.1 ± 2.3 mmHg (mean ± standard deviation; n = 7313 × 2). Mean IOP levels in male and female subjects were 14.1 ± 2.3 mmHg and 14.1 ± 2.2 mmHg, respectively. There was no difference in IOP between male and female subjects. Multiple regression analysis indicated that IOP had negative correlations with age, corneal radius and refraction (p < 0.0001), and positive correlations with CCT, systolic BP and BMI (p < 0.0001). Conclusions: In a large‐scale population of ophthalmologically normal Japanese subjects, IOP measured by GAT was significantly and negatively correlated with age. It was also negatively correlated with corneal radius and refraction, and positively with CCT, systolic BP and BMI.

“…Myopia, a very common condition in Japan [21], is often accompanied by higher IOPs [22][23][24][25][26], abnormal optic nerve head morphology [27][28][29], parapapillary atrophy [30], thin lamina cribrosa [31], and impaired retinal microcirculation [32,33]. All of these factors are closely associated with the development of glaucoma, and myopia has been considered an important risk factor for the development and progression of POAG [7,13,25,[34][35][36][37].…”

The relationship between intraocular pressure and refractive error adjusting for age and central corneal thickness

Abstract: Our results confirm the positive association between IOP and increasing degrees of myopia. This finding would support the hypothesis that the relationship between glaucoma and myopia might be pressure mediated.
