Role of 24-Hour Intraocular Pressure Monitoring in Glaucoma Management. Journal of ophthalmology Glaucoma is the leading cause of irreversible blindness worldwide and the prevalence is on the rising trend. Intraocular pressure (IOP) reduction is the mainstay of treatment. The current practice of IOP monitoring is based on spot measurements during clinic visits during office hours. However, there are up to 50% of glaucoma patients who had normal initial IOP, while some treated patients continued to have progressive glaucomatous optic nerve damage even with a low IOP. Recent studies have shown that the IOP of glaucoma patients fluctuated during the day with different patterns, and some of them had peak IOP outside office hours. These findings provided us with new insights on the role of 24-hour IOP monitoring in managing normal tension glaucoma and patients with progressive deterioration despite apparently well-controlled IOP. Nevertheless, results to date are rather inconsistent, and there is no consensus yet. In this review, we briefly highlighted the current modalities of 24-hour IOP monitoring and summarized the characteristic 24-hour IOP pattern and the clinical relevance of IOP parameters in predicting glaucomatous progression in different glaucoma subtypes. We also discussed the therapeutic efficacy of current glaucoma treatment modalities with respect to the mentioned 24-hour IOP profiles, so as to strengthen the role of 24-hour IOP monitoring in identifying and stratifying the risks of progression in glaucoma patients, as well as optimizing treatments according to their IOP profiles. 10.1155/2019/3632197
Meta-analysis of 24-hour intraocular pressure studies evaluating the efficacy of glaucoma medicines. Stewart William C,Konstas Anastasios G P,Nelson Lindsay A,Kruft Bonnie Ophthalmology PURPOSE:To evaluate efficacy and safety data of currently available ocular hypotensive medicines derived from 24-hour studies, of similar design, in patients with primary open-angle glaucoma (POAG), exfoliative glaucoma, or ocular hypertension (OH). DESIGN:Meta-analysis of published articles evaluating patients with POAG, exfoliative glaucoma, or OH. METHODS:We included articles that were randomized, prospective, single- or double-masked, comparative studies of ocular hypotensive therapies over 24 hours. Each article selected contained an untreated baseline, >or=4-week treatment period, >/=20 patients per treatment arm, and >or=6 time points not spaced >5 hours apart and used Goldmann applanation or Tonopen tonometry (supine measurements) to measure intraocular pressure (IOP). MAIN OUTCOME MEASURE:Twenty-four-hour IOP efficacy. RESULTS:This analysis included 864 separate 24-hour treatment curves from 386 patients in 28 treatment arms from 11 studies. A statistical difference in the mean diurnal pressure decrease existed between monotherapy treatments for POAG/OH patients, with bimatoprost (29%) and travoprost (27%) showing the greatest 24-hour reduction (P = 0.026). Timolol 0.5% was less effective than latanoprost (24% vs. 19% reduction) but decreased the pressure at each night time point (P = 0.0003). Dorzolamide showed a 19% 24-hour pressure reduction and brimonidine 0.2% a 14% one. In exfoliative glaucoma patients, latanoprost and travoprost showed higher baseline and treatment pressures, although the pressure reductions (29% and 31%, respectively) were greater generally than observed with POAG/OH. An evening-dosed latanoprost/timolol fixed combination reduced the pressure 33%, and the dorzolamide/timolol fixed combination (DTFC), 26%. However, the power to detect a difference for this specific comparison was probably low, due to the limited number of patients (n = 20) in the DTFC group. A statistical difference between evening-dosed (24%) and morning-dosed (18%) latanoprost (P<0.0001) was noted, but not between evening (27%) and morning (26%) travoprost (P = 0.074). The mean reduction of night time points was statistically lower than day time points for latanoprost (P = 0.031), timolol (P = 0.032), and brimonidine (P = 0.050), but not for dorzolamide. Dorzolamide (P = 0.60), travoprost (P = 0.064), and bimatoprost (P = 0.057) did not demonstrate nighttime pressures lower than daytime ones. The mean reduction of night time points was statistically lower than that of day time points for latanoprost (P = 0.031), timolol (P = 0.032), and brimonidine (P = 0.050), but not for dorzolamide (P = 0.60), bimatoprost (P = 0.057), travoprost (P = 0.064). CONCLUSIONS:Similar relative efficacies generally exist in various classes of ocular hypotensive agents during night and day hours. 10.1016/j.ophtha.2007.10.004
24-h Efficacy of Glaucoma Treatment Options. Konstas Anastasios G P,Quaranta Luciano,Bozkurt Banu,Katsanos Andreas,Garcia-Feijoo Julian,Rossetti Luca,Shaarawy Tarek,Pfeiffer Norbert,Miglior Stefano Advances in therapy Current management of glaucoma entails the medical, laser, or surgical reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which is commensurate with either stability or delayed progression of visual loss. In the published literature, the hypothesis is often made that IOP control implies a single IOP measurement over time. Although the follow-up of glaucoma patients with single IOP measurements is quick and convenient, such measurements often do not adequately reflect the untreated IOP characteristics, or indeed the quality of treated IOP control during the 24-h cycle. Since glaucoma is a 24-h disease and the damaging effect of elevated IOP is continuous, it is logical that we should aim to understand the efficacy of all treatment options throughout the 24-h period. This article first reviews the concept and value of diurnal and 24-h IOP monitoring. It then critically evaluates selected available evidence on the 24-h efficacy of medical, laser and surgical therapy options. During the past decade several controlled trials have significantly enhanced our understanding on the 24-h efficacy of all glaucoma therapy options. Nevertheless, more long-term evidence is needed to better evaluate the 24-h efficacy of glaucoma therapy and the precise impact of IOP characteristics on glaucomatous progression and visual prognosis. 10.1007/s12325-016-0302-0
Twenty-four hour efficacy of glaucoma medications. Konstas Anastasios G P,Katsanos Andreas,Quaranta Luciano,Mikropoulos Dimitrios G,Tranos Paris G,Teus Miguel A Progress in brain research Current medical therapy of glaucoma aims to attain a meaningful and consistent reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which will commensurate with either stability, or delayed progression of visual loss. Glaucoma is a 24-h disease and the damaging effect of elevated IOP is continuous. Therefore, it is reasonable that we should endeavor to identify the true efficacy of currently available and future antiglaucoma medications throughout the 24-h period. This review chapter deals first with the concept and value of diurnal and 24-h pressure monitoring. It then evaluates existing evidence on the 24-h efficacy of medical therapy options. Unfortunately, significant gaps exist in our present understanding of the short-term and particularly the long-term 24-h efficacy of most antiglaucoma medications. More long-term controlled evidence is needed in the future to improve our understanding of the 24-h efficacy of current medical glaucoma therapy, the ideal 24-h target pressure and the precise impact of IOP characteristics upon the different stages of the various forms of glaucoma. 10.1016/bs.pbr.2015.06.010
