“…In our study, the mean pressure-lowering effect of bimatoprost (7.9 mmHg, 33.4%) and latanoprost (7.1 mmHg, 30.6%) are less than that reported in the study by Walters et al 21 Lack of variation has been shown in several studies to be important in helping to prevent long-term progressive VF loss with glaucoma. 1,2,22 We additionally evaluated the mean range of IOP as Konstas et al's 14 study. The untreated mean range of IOP is approximately 7 mmHg in previous reports.…”

“…In a retrospective chart review of 29 treated POAG and NTG patients, Hughes et al 39 found that although the mean office IOP determined in previous visits was similar to the mean 24-hour values, the peak IOP during 24-hour monitoring was almost 5 mm Hg higher than the peak office IOP. The mean circadian IOP variation amplitude was 9.4 mm Hg.…”

Abstract. This review analyzes the currently available literature on circadian rhythms of intraocular pressure (IOP), blood pressure, and calculated ocular perfusion pressure (OPP) in patients with openangle glaucoma. Although adequately powered, prospective trials are not available. The existing evidence suggests that high 24-hour IOP and OPP fluctuations can have detrimental effects in eyes with glaucoma. The currently emerging continuous IOP monitoring technologies may soon offer important contributions to the study of IOP rhythms. Once telemetric technologies become validated and widely available for clinical use, they may provide an important tool towards a better understanding of longand short-term IOP fluctuations during a patient's daily routine. Important issues that need to be investigated further include the identification of appropriate surrogate measures of IOP and OPP fluctuation for patients unable to undergo 24-hour measurements, the determination of formulae that best describe the relationship between systemic blood pressure and IOP with OPP, and the exact clinical relevance of IOP and OPP fluctuation in individual patients. Despite the unanswered questions, a significant body of literature suggests that OPP assessment may be clinically relevant in a significant number of glaucoma patients.

Physiological ConsiderationsThe principal physiological entities that affect intraocular pressure (IOP) and its characteristics are the aqueous humor (AH) dynamics in healthy and glaucomatous eyes.The production of AH involves two consecutive processes. First, a portion of the plasma that reaches the vascular plexus of the ciliary processes is filtered through the fenestrated capillaries into the interstitial space between the vessels and the ciliary epithelia. Next, a portion of the filtrate is actively secreted by the ciliary epithelial cells into the posterior chamber.In humans, these processes are affected by age, circadian rhythm, topical and systemic medications, and the presence of glaucoma. 63,64,70,109,121 The rate of AH formation decreases with age: by 15--35% between age 20 and 80 years. 15,30 The rate of AH production in humans is significantly lower at night, 99,119 attributed to decreased endogenous circulating catecholamine levels, which may partly explain the decreased nocturnal efficacy of topical 26

“…Studies in humans describe the use of serial measurements of intraocular pressure (IOP) during periods of 24hours for the management of patients with glaucoma (Hughes et al 2003, Barkana et al 2006, Bagga et al 2009). The preliminary results of the development of an IOPC protocol for serial use in dogs with elevated IOPs found that IOPCs might be useful for monitoring IOP in this species, but warned of the development of superficial corneal ulceration, which was theorized to pose a likely challenge (Viera da Silva and Sanchez 2010).…”

Summary:Objectives:To establish an intraocular pressure curve protocol that is safe for corneal health and determining if they detect harmful elevations of intraocular pressure outside normal clinic hours. To determine inter-user variability and if repeated measurements affect intraocular pressures.Methods: Dogs with glaucoma were included in the first part of the study in which intraocular pressures were measured using three protocols. Protocol 1 used applanation tonometry every two hours over 24h. Protocols 2 and 3 used applanation or rebound tonometry, respectively, and measured intraocular pressures every three hours over 30h. Sixty additional intraocular pressure curves from dogs with glaucoma and 20 from healthy dogs were then analysed for inter-user variability. Results:128 Intraocular pressure curves were determined in 30 dogs. Protocol 1 resulted in one ulcer in five pressure curve measurements, Protocol 2 in one ulcer in 62 pressure curves, and Protocol 3 in no ulcers in 61. Elevated intraocular pressures were detected on 61 occasions, of which 26 developed outside normal clinic hours. Sixty-one additional intraocular pressure curves revealed that repeated measurements had no effect on intraocular pressure. Assessors had a significant variability in righteye but not left-eye readings.Conclusions: Protocol 3, using rebound tonometry every three hours for 30hr is safe and identified elevated intraocular pressures outside normal clinic hours in 12/30 (40%) of patients that single intraocular pressure measurement during consultation hours would not have identified. Intraocular pressure curves may be recommended for clinical practice and glaucoma studies.
