Filter by:Xal-Ease is a novel Pfizer-Pharmacia device aimed to significantly facilitate the Xalatan/Xalacom instillation and to avoid loss of Xalatan/Xalacom eye drops due to incorrect instillation. Patients on Xalatan/Xalacom who have consumed more than one bottle per month within a year according to consumption data drawn from the Clalit Health Services database, will use the Xal-Ease device for a year. The device is expected to reduce consumption of bottles and result in saving money for both patients and medical care providers.
The investigators plan to evaluate the additive effect of intracameral and subconjunctival injections of bevacizumab in trabeculectomies with other antimetabolites.
Primary congenital glaucoma, which presents at birth or in infancy, if left untreated, may threaten vision. The incidence of congenital glaucoma varies among different geographic locations and ethnic groups. Three genetic loci for primary congenital glaucoma (GLC3A in 2p21, GLC3B in 1p36, GLC3C in 14q24.3) were identified. CYP1B1 (cytochrome P450 1B1 ) gene, in the GLC3A locus is the main known gene and different CYP1B1 mutations has been described. The genetic characteristics in south Korean patients with primary congenital glaucoma have not been reported yet and the genotype-phenotype correlations, the prognosis and the genetic counseling have not also been established. This study represents the first repot about the rate of CYP1B1 mutations, the genotype-phenotype correlations in south Korean patients with primary congenital glaucoma. Patients with primary congenital glaucoma and their family will be analyzed for CYP1B1 mutations by direct sequencing of polymerase chain reaction fragments. Primary congenital glaucoma will be diagnosed according to the clinical parameters by glaucoma specialists. Patients were classified to several groups according to the pattern of mutations. Clinical parameters and genotype correlation will be compared between groups
Glaucoma affects 66 million people worldwide and is the leading cause of irreversible blindness, and Primary angle-closure glaucoma (PACG) is a major form of glaucoma in Asia. Laser peripheral iridotomy (LPI) has been advocated as the first line treatment in all cases of PACG. In addition to relieving the relative pupil block element of the condition, it can open up the drainage angle, alleviating appositional and synechial angle-closure and in the long-term this may control intraocular pressure (IOP) and prevent progression of glaucomatous optic neuropathy. However recent data indicate that iridotomy is not successful in controlling IOP in the long term, and the majority of cases develop a clinically significant rise in IOP requiring medical therapy or surgery. Laser trabeculoplasty has been a recognized treatment option for Primary open angle glaucoma (POAG) since the 1980s. Recently a more selective and less destructive method of performing laser trabeculoplasty has evolved. Selective Laser Trabeculoplasty (SLT) specifically targets the pigmented trabecular meshwork cells without producing collateral damage and destruction to adjacent structures. Morphologic study performed on human autopsy eyes treated with SLT noted no structural or collateral thermal damage to the trabecular beams in the uveal and corneoscleral meshwork. As SLT specifically has its effect on the targeted pigmented trabecular meshwork it is unlikely to generate PAS. It may be a useful treatment option for PACG patients in whom the angle has widened following laser peripheral iridotomy. The proposed study is a randomized controlled trial to assess the effectiveness of SLT in reducing IOP in cases of PACG in which the angle has opened up following LPI, but IOP remains high(>21 mmHg). 100 subjects will be randomized to receive either SLT or medical treatment to achieve IOP control. They will be followed up for 6 months.
Omeprazole is a safe drug listed in OTC drug due to its safety. It acts by irreversible inhibition of K/H ATP ase pump and also Na/K ATP ase, Na/H ATP ase.Considering these actions the effect of omeprazole on decreasing intra ocular pressure is an issue of debate.In this Randomized Clinical Trial conducted in labafinejad hospital, patients with glaucoma who need to take omeprazole due to GI problem are evaluated in two groups including placebo and drug users. The effect will be finally assessed.
Glaucoma is the leading cause of irreversible blindness worldwide. With ageing of the population, glaucoma morbidity will rise, causing increased health care costs and economic burden for a condition in which visual loss, once established, cannot be reversed. In contrast to western countries, primary angle closure glaucoma (PACG) is a major form of glaucoma in Asia. In a recent population based survey in Singapore, the prevalence of glaucoma was 3.2% in the Chinese population over 40. Glaucoma was the leading cause of blindness, with PACG the most visually destructive form of the disease. Laser iridotomy is the current first line treatment for PACG. It acts by relieving pupil block, which in turn may reduce intraocular pressure (IOP) and prevent progression of glaucoma. However recent data indicate that iridotomy is not successful in controlling IOP in the long term, and the majority of cases develop a clinically significant rise in IOP requiring medical therapy or surgery. Argon laser peripheral iridoplasty (ALPI) offers a new therapeutic option for PACG. The procedure consists of placing contraction burns in the iris periphery which results in contraction of the iris stroma and opening of the angle. The proposed study is a 2-centre randomized controlled trial to determine whether ALPI is an effective and safe treatment in the management of PACG. 210 patients with PACG and high IOP (>21 mmHg) following laser iridotomy will be randomized to receive ALPI or medical treatment to achieve IOP control. Subjects will be followed up for 12 months and the outcome criteria will be the rate of medical treatment and surgery in each group, and the angle width and configuration. This will be the first RCT worldwide to address the role of ALPI in PACG. The study findings will have great relevance for the prevention of glaucoma blindness in the elderly.
The primary aim of the Erlangen´s Glaucoma Contrast Sensitivity-Study (EGCS-Study) is the evaluation of the diagnostic and prognostic validity of a diagnostic procedure, measuring contrast sensitivity. No therapeutic studies are performed.
This randomized, controlled trial (RCT) compares the efficacy and safety of Ahmed Glaucoma Valve (AGV) implantation alone, with 3 minutes MMC application or with a single layer coverage of amniotic membrane. Outcomes include intraocular eye pressure (IOP), postoperative glaucoma medication and complications. AGV implantation site will be superior or inferior based on indication and these groups will be randomized separately.
The aim of the study is to investigate pressure lowering effect of two surgical methods canaloplasty and trabeculectomy in patients with open angle glaucoma, in which under local pressure lowering therapy the progression of the disease could not be stopped, and thus a pressure lowering surgical intervention is necessary. The risks in the postoperative course in Canaloplasty in the literature as lower than for the trabeculectomy with mitomycin-C. Conversely, large glaucoma centers questioning the effectiveness of permanent pressure lowering of canaloplasty. Precisely this question is investigated in the study.
Measurement of RNFL thickness by OCT is at a cornerstone for the correct diagnosis and monitoring of progression of glaucomatous optic neuropathy. Spectral domain technology has enabled better reproducibility with better axial resolution in the measurement of RNFL thickness. A comparative study among Stratus, Cirrus and RT-View will enable clinicians to determine differences among various instruments.
