“…Numerous studies in the last decades have shown that IOP in humans undergoes circadian variations, with higher peaks in the morning and lower ones in the afternoon and evening. [1][2][3] It is also well known that IOP varies with the body position. IOPs have been reported to be higher when the patient's body is in the supine position (SUP) than in the upright position (UP).…”

“…2 Diurnal variations can affect the reliability of IOP measurements, and thus also influence diagnosis and follow-up of ocular hypertension and the corresponding therapeutic strategy, which is very important to clinical practice and research activity. [3][4][5] However, other cornea-related properties could be implicated as one source of IOP measurement variation, including the biomechanical properties of the cornea.…”

The present study confirms that intraoffice hour values of CH and corneal resistance factor are quite stable among a population of young healthy adults. However, average changes in these parameters over time correlate well with the changes in IOP values obtained with the same instrument, suggesting that diurnal variations of IOP could be at least in part related with changes in the biomechanical behavior of the cornea against the mechanical stimuli used by current non-contact tonometers. The most stable period to measure IOP and biomechanical parameters with ORA was in the afternoon.

“…11,12 The relationship of IOP with the systemic parameters need a special concern as raised IOP is the only modifiable risk factor for glaucoma. 13 The development of optic nerve damage and visual field defects are more likely associated with the raised IOP. 14 Most of the available data about prevalence of glaucoma in India is from the south and the north India.…”

Background: Raised intaocular pressure is considered as a major risk factor for developing optic neuropathy. Intraocular pressure (IOP) depends on various systemic and local factors and it has been postulated that IOP increases proportionately with increase in systolic blood pressure and increase in degree of obesity. The aim of this study was to compare the Body Mass Index (BMI) and Intraocular Pressure (IOP) in adult population.Methods: Four hundred ninety nine participants (284 male, 215 female) aged between 20 to 70 years were included in the cross-sectional study. On the basis of BMI subjects were divided into four categories i.e. underweight, normal weight, overweight and obese as per revised body type classification for Indian population recommended by Ministry of Health and Diabetes foundation of India. The mean IOP difference was 14.6±1.8 as compared amongst the four categories.Results: The participants were divided into six categories according to age and the mean IOP of different age groups was calculated. The changes in the mean IOP of males was 15.8±2.5 mm of Hg and the mean IOP of females was 14.7±2.2 mm of Hg. The results of the current study were statistically significant p<0.01.Conclusions: By concluding the current study as well as in the previous published literature, the findings of the current study were statistically significant. IOP was positively correlated with BMI. However, the clinical significance cannot be confirmed by the minor deviation in the IOP as well as BMI of the participants.
