Diurnal Variation of Intraocular Pressure in the Normal Eye

Relationship Between Diurnal Variations of Episcleral Venous Pressure and Intraocular Pressure

“…Our results show a consistent trend of higher IOP and EVP in the mornings, followed by a decline throughout the day in both groups. These findings are consistent with previous studies which have reported higher IOP in the morning and lower values in the later afternoon or evening, 43 – 52 and no difference in OPP during the diurnal period. 37 However, those studies did not measure EVP concurrently with IOP.…”

Intraocular pressure measurement in patients with previous LASIK surgery using pressure phosphene tonometer

“…In over 68% of cases, the difference will be less than 3.59 mmHg. In fact, the difference between the assessment of IOP between the preoperative and postoperative value lies within the diurnal variation range published previously 22–25 .…”

Effects of topical 2% dorzolamide hydrochloride alone and in combination with 0.5% timolol maleate on intraocular pressure in normal feline eyes

“…Diurnal fluctuation in intraocular pressure followed a distinct pattern, which was consistently observed in all 24 cats. This was not an unexpected finding, as variation in IOP throughout the day has been previously described in cats 27 and also exists in humans, 28 rabbits, 29 monkeys 30 and dogs 31 . In cats the lowest IOP has been reported in the morning, followed by a rise during the day and with the highest IOP occurring in the evening 27 .…”
