Intraocular Pressure in Children Measured Under General Anesthesia

Development of the primate area of high acuity. 1. Use of finite element analysis models to identify mechanical variables affecting pit formation

“…There is evidence that IOP contributes to eye growth in humans and monkeys. IOP is considerably higher in anesthetized newborn humans, decreasing by 27% from birth (21.4 mm Hg) to year 9 (15.7 mm Hg), at which time it is still 30% greater than that of the anesthetized adult (12 mm Hg) (Kornblueth et al, 1964). A declining IOP with age was also observed in anesthetized Macaca mulatta where IOP declined from 21 mm Hg to 16 mm Hg from birth to 6 years (De Rousseau & Bito, 1981).…”

The Intraocular Pressure

“…De Rousseau and Bito (1981) have discussed the effects of age during the earliest stages of growth in human children; probably the most reliable study, using a single technique is that of Kornblueth et al (1964) who found the pressure to decrease gradually from 21Τ ±0-3 mmHg in 0-1 year-olds to 15*7 ±0-4 mmHg in 8-9 year-olds. The measurements were made under general anaesthesia and so should be compared with a value of 12 mmHg for adult man under these conditions (Kornblueth et ai, 1959).…”

Change in intraocular pressure during maturation in Labrador Retriever dogs

“…Previous reports indicated that IOP varies with age. Many studies in humans have demonstrated higher IOP in immature vs. mature individuals; however, some showed the opposite 6–11 . Previous work in the Samoyed dog, Rhesus monkey, and American alligator demonstrated higher IOP in younger individuals 12–14 .…”

[12][13][14] It has been theorized that relatively increased IOP in young animals may serve to drive growth of the globe.…”
