Switching from a preserved to a preservative-free prostaglandin preparation in topical glaucoma medication.
2010
. Purpose: The purpose of this study was to investigate the tolerability and intraocular pressure (IOP) reducing effect of the first preservative-free prostaglandin tafluprost (Taflotan®) in patients exhibiting ocular surface side-effects during latanoprost (Xalatan®) treatment. Methods: A total of 158 patients were enrolled in this open-label multicentre study. Eligible patients had to have at least two ocular symptoms, or one sign and one symptom, during treatment with latanoprost. At baseline, the patients were directly switched from latanoprost to preservative-free tafluprost for 12 weeks. The patients were queried for ocular symptoms, and ocular signs were assessed by using tear brea…
European study of the efficacy of a cross-linked gel stent for the treatment of glaucoma
2020
indexation en cours.; PURPOSE: This study investigated the efficacy and safety of a cross-linked collagen stent (XEN 45) with or without cataract surgery in the treatment of glaucoma. SETTING: Real-life setting. DESIGN: Prospective, open-label, multicenter clinical trial. METHODS: Eligible patients with glaucoma inadequately controlled by treatment, or poor compliance or intolerance to topical therapy were included. Patients were divided into those with implant only (solo group; phakic and pseudophakic patients) and implant combined with cataract surgery (combo group). Differences in average intraocular pressure (IOP) and number of medications between baseline and study end (12 months), and…
Effect of bicycle ergometer test on intraocular pressure in elderly athletes and controls.
2009
To evaluate the effect of intensive physical exercise on intraocular pressure (IOP) in 66- to 85-year-old subjects IOP was measured before and after a maximal bicycle ergometer test. The non-glaucomatous subjects comprised 85 males and 36 female athletes and 16 male and 22 female controls of corresponding age drawn from a population register. IOP was measured using a non-contact tonometer. The results indicated a decrease (> or = 2 mmHg) in 34% of the subjects, no change in 57% and an increase in 9%. The decrease was more pronounced in subjects with higher pre-test values. In all four subjects with a pre-test value above 22 mmHg a reduction from 4 to 11 mmHg was observed. The change in IOP …
Randomized Trial of Brinzolamide/Brimonidine Versus Brinzolamide Plus Brimonidine for Open-Angle Glaucoma or Ocular Hypertension
2014
Introduction Fixed-combination intraocular pressure (IOP)—lowering medications simplify treatment regimens for patients requiring 2 ocular hypotensive agents to maintain sufficiently low IOP. The aim of this study was to evaluate the safety and efficacy of fixed-combination brinzolamide 1%/brimonidine 0.2% (BBFC) versus concomitant administration of brinzolamide 1% plus brimonidine 0.2% (BRINZ + BRIM) in patients with open-angle glaucoma or ocular hypertension. Methods This was a prospective, phase 3, multicenter, double-masked, 6-month trial. Patients who had insufficient IOP control with monotherapy or who were receiving 2 IOP-lowering medications were randomized 1:1 to receive twice-dail…
Posterior‐chamber phakic implantable collamer lenses with a central port: a review
2020
Abstract We aimed to summarize the outcomes reported following the implantation of the V4c implantable collamer lens with a central port (ICL, STAAR Surgical Inc) for myopia correction. A literature search in PubMed, Web of Science and Scopus was carried out to identify publications reporting clinical outcomes of patients who were implanted with the V4c ICL model and had a follow‐up period of at least 6 months. A total of 35 clinical studies published between 2012 and 2020 were included in the present review. A comprehensive analysis of the available data was performed, focusing on visual and refractive outcomes at different time‐points post‐surgery. In addition, adverse events and other pa…
Deep sclerectomy versus trabeculectomy with low-dosage mitomycin C: four-year follow-up
2006
<i>Aims:</i> To compare the long-term effects of low-dosage mitomycin C (MMC) in both deep sclerectomy (DSMMC) and trabeculectomy (TPMMC) on intraocular pressure (IOP). <i>Methods:</i> Analysis of extended follow-up of data from a prospective clinical trial. Forty patients were originally randomised to undergo either DSMMC (19 eyes) or TPMMC (21 eyes). Follow-up was performed at postoperative day 1, weeks 1, 2 and 3, as well as months 1, 3, 6, 9, 12, 18, 24, 36 and 48. Two- to three-week data were not included in the statistical analysis. Postoperative complications, number of antiglaucoma medications and IOP were recorded at each visit. Complete (no medications) and…
E-PTFE (Gore-Tex) implant with or without low-dosage mitomycin-C as an adjuvant in penetrating glaucoma surgery: 2 year randomized clinical trial.
2008
Purpose: To test the expanded polytetrafluoroethylene (ePTFE) as a new adjuvant in trabeculectomy. Methods: Consecutive glaucoma surgical inpatients were observed at the Department of Ophthalmology of Palermo University. Sixty patients (60 eyes) were randomly assigned to undergo trabeculectomy (T), trabeculectomy with mitomycin-C (TMMC), with ePTFE (TG) or with mitomycin-C and ePTFE (TGMMC). Postoperative visits were scheduled at 24 hr, 7 days, 1, 3, 6, 12, 18 and 24 months. Complete success and qualified success were assessed at two target intraocular pressure (IOP) levels – £21 and £17 mmHg – by Kaplan–Meier curves. Results: The postoperative IOP reduction was significant (P < 0.01) at th…
Biodegradable collagen matrix implant vs mitomycin-C as an adjuvant in trabeculectomy: a 24-month, randomized clinical trial
2011
AIM: To verify the safety and efficacy of Ologen (OLO) implant as adjuvant compared with low-dosage mitomycin-C (MMC) in trabeculectomy. METHODS: This was a prospective randomized clinical trial with a 24-month follow-up. Forty glaucoma patients (40 eyes) were assigned to trabeculectomy with MMC or OLO. Primary outcome includes target IOP at ≤21, ≤17, and ≤15 mm Hg; complete (target IOP without medications), and qualified success (target IOP regardless of medications). Secondary outcomes include bleb evaluation, according to Moorfields Bleb Grading System (MBGS); spectral domain optical coherence tomography (SD-OCT) examination; number of glaucoma medications; and frequency of postoperative…
Dietary polyunsaturated fatty acids reduce retinal stress induced by an elevation of intraocular pressure in rats.
2011
International audience; N-6 and n-3 polyunsaturated fatty acids (PUFAs) have been shown to prevent tissue release of inflammatory molecules. We have shown that a combination of n-6 and n-3 PUFAs is more efficient than single supplementations on the long-term consequences of intraocular pressure elevation. We hypothesized that such an association is also more effective during early retinal stress by modifying retinal proinflammatory prostaglandin and cytokine productions. Rats were supplemented for 3 months with n-6 PUFAs, n-3 PUFAs, or both n-6 and n-3 PUFAs. After 3 months, a surgical elevation of intraocular pressure was induced. Retinal morphometry and glial cell activation were evaluate…
Does general anesthesia have a clinical impact on intraocular pressure in children?
2016
Summary Background Reliable measurement of intraocular pressure (IOP) is crucial in pediatric patients with suspected glaucoma. General anesthesia (GA) is usually needed in infants to allow a thorough examination. However, anesthesia itself may influence IOP, depending on the type used and the depth of sedation. The purpose of this study was to evaluate the normal distribution of IOP during GA in healthy children and to analyze differences in IOP relative to the anesthetics used and the measurement time point. Methods Approval for this observational study was received from the local institutional review boards and written informed consent was obtained from the children's parents. A total of…
