New insights into autoantibody profiles from immune privileged sites in the eye: a glaucoma study.

2011

Glaucoma is a chronic neurodegenerative disease and one of the leading causes of blindness. Autoantibody based immune processes are assumed to be involved in its pathogenesis. However, it is still unclear to what extent autoantibody patterns found in the eye (aqueous humor) are congruent to systemic autoantibodies (blood). Consistency would underline the specificity of known serum antibody markers for glaucoma. In this study we used antigen microarrays to analyze autoantibody reactivities in sera and corresponding aqueous humor samples of primary open-angle glaucoma patients (N=37) and non-glaucomatous controls (N=31). Compared to control subjects several divergent immunoreactivities were i…

Does the renin-angiotensin system also regulate intra-ocular pressure?

2009

The renin-angiotensin-aldosterone system is known to play an essential role in controlling sodium balance and body fluid volumes, and thus blood pressure. In addition to the circulating system which regulates urgent cardiovascular responses, a tissue-localized renin-angiotensin system (RAS) regulates long-term changes in various organs. Many recognized RAS components have also been identified in the human eye. The highly vasoconstrictive angiotensin II (Ang II) is considered the key peptide in the circulatory RAS. However, the ultimate effect of RAS activation at tissue level is more complex, being based not only on the biological activity of Ang II but also on the activities of other produ…

Analysis of Autoantibodies Against Human Retinal Antigens in Sera of Patients with Glaucoma and Ocular Hypertension

2008

The aim of this study was to show that complex antibody patterns against retinal antigens in sera of patients with glaucoma, found in previous studies, are autoantibodies against human antigens.Sera of 179 patients were collected at the Department of Ophthalmology (University of Mainz, Germany): non-glaucomatous control patients (n=45), primary open-angle glaucoma (n=45), ocular hypertension (n=44), and normal tension glaucoma patients (n=45). The sera were tested against Western blots of human retinal antigens. IgG antibody patterns were analyzed by multivariate statistical techniques, and some significant antigens were identified by mass spectrometry.All subjects, even healthy ones, showe…

Meta-Analysis of Articles Evaluating Routine Intraocular Pressure Control in Monotherapy in the United States and Germany

2009

Pur P ose . To evaluate routine intraocular pressure (IOP) control in monotherapy patients in the United States and Germany. Methods . Meta-analysis of published articles. We included articles that were prospective studies of ocular hypotensive therapies that measured an unaltered (visit 1) IOP on monotherapy before enrolling into a clinical trial. results . This meta-analysis included 5 studies with 7913 patients, of whom 3245 were from the United States (n=1) and 4668 were from Germany (n=4). In the United States, 2939 patients (91%), and in Germany, 4059 patients (87%), had glaucoma (p<0.0001). Of these, all the US patients (100%) and 2694 (58%) of those from Germany were treated with mo…

Goldmann Applanation Tonometry Using Sterile Disposable Silicone Tonometer Shields

1996

Abstract Purpose: Placement of a sterile single-use cover over the tonometer tip may be a convenient and safe alternative method to repeated chemical disinfection. This study was undertaken to evaluate the accuracy and performance of Goldmann applanation tonometry using a sterile disposable silicone tonometer shield over the biprism tip. Methods: The same investigator measured intraocular pressure in 120 eyes with and without the shield. The eyes were tested randomly first with either the uncovered or the covered tonometer to control for the possible effects of repeated tonometry influencing measurement differences. Readings were recorded independently in a masked fashion. Results: The intr…

The effects of prostaglandin F2α in the human eye

1985

The ocular effects of 200 micrograms of topically applied prostaglandin F2 alpha were studied in 18 nonglaucomatous volunteers. A fall in intraocular pressure was seen in the prostaglandin-treated eyes when compared with the placebo-treated control eyes. The maximum intraocular pressure reduction was observed at the 7th h and hypotensive ocular effect persisted for 24 h. Prostaglandins did not produce any change in pupillary diameter or signs of intraocular inflammation visible by anterior segment biomicroscopy or iris fluorescein angiography. The drug caused side effects: conjunctival hyperemia was constant and many patients complained of ocular smarting and headache. It could be useful in…

Comparison of Dynamic Contour Tonometry and Goldmann Applanation Tonometry in Glaucoma Patients and Healthy Subjects

2006

To investigate the agreement in the measurement of intraocular pressure (IOP) obtained by dynamic contour tonometry PASCAL (DCT-PASCAL) and Goldmann applanation tonometry (GAT) in glaucoma eyes and healthy eyes with different central corneal thickness (CCT).Prospective cross-sectional study.In a randomized order, three consecutive IOP measurements were performed on 197 eyes of 107 subjects by one examiner using both DCT-PASCAL and GAT on all eyes. Furthermore, ultrasonic pachymetry was performed. The Spearman correlation coefficient (r) was determined to compare IOP readings between DCT-PASCAL and GAT. Regression-based Bland and Altman analysis was used to evaluate agreement between the ins…

Efficacy and safety of tafluprost 0.0015% and timolol maleate 0.5% fixed combination in patients with ocular hypertension or open-angle glaucoma.

2014

Lowering intraocular pressure (IOP) is at present the only therapeutic approach to the treatment of glaucoma proven to be successful. The choice of therapy must take into account efficacy, tolerability, safety, quality of life, adherence and cost. Monotherapy fails to achieve a satisfactory IOP reduction in 40 - 75% of glaucoma patients after2 years of therapy. So far, three prostaglandin/timolol maleate 0.5% fixed combinations (FCs) are available.This review provides a background on the tafluprost-timolol FC (TTFC, Santen Oy) and its individual compounds. It summarizes the data on efficacy and safety, including comparative data with prostaglandin/timolol FCs already available.Tafluprost is…
