“…11,12 IOP measurements with poor reported reliability or taken more than 2 minutes after induction of general anesthesia were excluded from analyses. The association of CCT with IOP and spherical equivalent refractive error was evaluated using linear regression models adjusting for age, racial/ethnic group, and gender.…”

“…In deed. whereas it is claimed in several animal and human studies that general anesthesia usually produces a lowering of the intraocular pressure [22][23][24], studies performed in chil dren have not confirmed this view, finding no intraocular pressure value changes under gen eral anesthesia [17,19,25,26]. The author has observed that the tonometer type has more influence than does the kind of anesthetic drug used, and, whether halothane has a tensional effect or not, it was more hypotensive.…”

Whereas the values of 120/70 mm Hg are universally recognized as being normal for the parameter of systemic blood pressure, the value for ‘normal intraocular pressure’ remains very vague. Indeed, values between 7 and 21 mm Hg are often considered normal. However, a careful review of the literature and original data reported here suggest that the intraocular pressure in normal subjects, although dynamic, is a more accurate parameter than is generally expected. The normal value during the day in healthy, young adults is about 12 ± 2 mm Hg, and it increases by 1mm Hg per decade after 40 years of age.

“…5 Halothane was reported to significantly lower IOP. 4 Controversy still exists as to the extent to which IOP is reduced after general anesthesia with gas anesthetics. ln a study comparing IOP measurements of infants under bath awake and sedated conditions, Quigley found that the IOP in the awake state was similar to that after ketamine sedation, whereas gas anesthetics similar to sevoflurane lowered IOP.…”
