Current perspectives on the use of anti-VEGF drugs as adjuvant therapy in glaucoma
The approval of one of the first anti-vascular endothelial growth factor (VEGF) agents for the treatment of neovascular age-related macular degeneration one decade ago marked the beginning of a new era in the management of several sight-threatening retinal diseases. Since then, emerging evidence has demonstrated the utility of these therapies for the treatment of other ocular conditions characterized by elevated VEGF levels. In this article we review current perspectives on the use of anti-VEGF drugs as adjuvant therapy in the management of neovascular glaucoma (NVG). The use of anti-VEGFs for modifying wound healing in glaucoma filtration surgery (GFS) is also reviewed. Selected studies investigating the use of anti-VEGF agents or antimetabolites in GFS or the management of NVG have demonstrated that these agents can improve surgical outcomes. However, anti-VEGF agents have yet to demonstrate specific advantages over the more established agents commonly used today. Further studies are needed to evaluate the duration of action, dosing intervals, and toxicity profile of these treatments
A Comparison of Travoprost, Latanoprost, and the Fixed Combination of Dorzolamide and Timolol in Patients with Pseudoexfoliation Glaucoma
Effect of hospitalization on 24-h ambulatory blood pressure of hypertensive patients
The aim of this study is to assess the effect of hospital admission on 24-h ambulatory blood pressure (ABP) in hypertensive subjects. Treated or untreated hypertensive adults with open-angle glaucoma underwent inpatient and outpatient 24-h ABP monitoring in a random order 4 weeks apart. Awake ambulatory hours, awake in-bed hours and sleep hours were reported by participants. The nighttime-to-daytime ABP dip (%) and the sleeping-to-awake dip (ambulatory and in-bed) were determined using the two ABP recordings. A total of 40 subjects were analyzed (mean age 65.7±8.4 (s.d.) years, n=19 men). Daytime systolic BP (SBP) was lower in the hospital than in the outpatient setting (mean difference 4.3±10.4 mm Hg, P=0.01), as was the awake ambulatory SBP (mean difference 5.0±11.1 mm Hg, P=0.008). No differences were detected in 24 h, nighttime or sleeping SBP or in any of the respective diastolic outpatient vs. inpatient ABP measurements. The nighttime SBP dip (vs. daytime) was larger in the outpatient setting (8.9±7.5% and 5.2±4.7%, respectively; P=0.003). Sleeping SBP dip (vs. awake ambulatory and awake in-bed) was also larger in the outpatient setting (11.1±7.3 and 7.8±5.9%, respectively; P0.02) with no difference in diastolic ABP. These data suggest that inpatient 24-h ABP monitoring does not reflect the usual BP level during routine daily life, nor does it represent the usual diurnal pattern of an individual. Relying on the 24-h ABP monitoring performed in the hospital environment may lead to an underestimation of ABP and an overdiagnosis of non-dippers. Therefore, 24-h ABP monitoring for decision making regarding diagnosis and treatment of hypertension should be performed only in the routine daily conditions of each individual. © 2010 The Japanese Society of Hypertension All rights reserved
Untreated 24-h intraocular pressures measured with Goldmann applanation tonometry vs nighttime supine pressures with Perkins applanation tonometry.
AIMS:
To compare supine nighttime intraocular pressure measurements with Perkins applanation tonometry to 24-h sitting intraocular pressures with Goldmann applanation tonometry.
METHODS:
A prospective, untreated, uncontrolled, observational cohort of qualified consecutive ocular hypertensive or primary open-angle glaucoma patients. Patients underwent sitting intraocular pressure measurements over 24-h by Goldmann and patients had their supine nighttime intraocular pressure measurements by Perkins.
RESULTS:
In 100 completed patients, the mean intraocular pressure at 1000, 2200, 0200 and 0600 hours while sitting was 22.5+/-3.7 mm Hg, and in the supine position, 23.5+/-4.3 mm Hg (P<0.001). The mean sitting Goldmann intraocular pressures across the three daytime points was 23.3+/-3.4 mm Hg and across three nighttime points was 21.5+/-4.0 mm Hg (P<0.001). In contrast, the mean daytime sitting Goldmann intraocular pressure was not different than the mean nighttime supine intraocular pressure evaluated with Perkins (22.8+/-4.4 mm Hg, P=0.07). However, only 70% of patients were within 1.0 mm Hg of the highest daytime reading for all nighttime supine and sitting intraocular pressures.
CONCLUSION:
This study suggests that with Perkins applanation tonometry the untreated mean supine intraocular pressures are not higher at night than daytime sitting Goldmann applanation tonometry. However, the highest daytime sitting intraocular pressure measurement does not consistently predict the highest nighttime sitting or supine intraocular pressure value
