Active clinical trials for "Exfoliation Syndrome"

The study is an observational analysis of patients' medical data recorded in a large-scale register, both retrospective (for patients operated and data recorded before 2018) and prospective (for data collected after 2018) in nature.Patients' medical data contained in the register will be analysed to determine the efficacy of the treatments they received during their follow-up at the investigation centre.

The study aims to compare the endothelial cell count in patients with pseudoexfoliation syndrome to the the endothelial cell count in normal patients above the age of 50.

The purpose is to determine if an intracameral solution of 0.2% tropicamide and 2% phenylephrine can dilate the pupil for cataract surgery as well as pre-operative topical 1% tropicamide and 5% phenylephrine. We will be looking at two separate groups of patients, those with and those without pseudoexfoliation syndrome. We will be looking at how each method affects the size of the pupil at the beginning and at the end of cataract surgery. In addittion, we will look at what effect the two different methods have on blood pressure and heart rate in the pre-operative, peri-operative and post-operative periods.

The investigators hypothesize that KeraSys is a safe as Tutoplast to cover the tube of the Molteno 3 glaucoma drainage device during surgery

Modern phacoemulsification techniques have made cataract surgery safe and efficient over the past several decades. Although the phacoemulsification procedure has improved greatly, cataract surgery still involves trauma. One of the surgical traumas during cataract surgery is the direct trauma of the anterior uvea, resulting in a later chronic immune reaction of the uvea to the implanted intraocular lens (IOL). 1 The breakdown of the blood-aqueous barrier (a measure of the uveal reaction) clinically presents as flare in the anterior chamber. 2 Petternel et al. 3 explained that the protein content of the aqueous humor may mainly arise from the iris root and iris vessels in the anterior chamber. The peak of this flare and cell intensity in the anterior chamber was shown to be reached during the first two days after cataract surgery 4 and flare levels were back to the preoperative values about one year after cataract surgery. 5, 6 Influencing factors are surgical technique 7, perioperative treatment 8, IOL biomaterial and design 9 and host reaction to the IOL. In this study the otherwise same IOL concerning material and design, but one with a new surface modification will be compared to assess the influence on aqueous flare and cell intensity in the anterior chamber. The Polylens (Polytech, Rossdorf, Germany) is a hydrophobic acrylic single-piece open-loop IOL and is available with the standard surface and a novel modified surface. To assess the efficacy of the newly modified surface of the Polylens IOL compared to the same IOL without a modified surface concerning flare and cell intensity in the anterior chamber as well as cellular components on the IOL surface and lens epithelial out-growth from the rhexis after cataract surgery in eyes of patients with diabetes mellitus and pseudoexfoliation syndrome, which typically have a higher incidence of post-operative intra-ocular inflammation.

OBJECTIVE To evaluate the efficacy of bromfenac ophthalmic solution 0.09% for reducing postoperative inflammation in eyes with pseudoexfoliation syndrome (PEX) undergoing cataract surgery and receiving standard postoperative eye drops (dexamethasone 0.1% plus tobramycin 0.3% ophthalmic solution). DESIGN Two arms, parallel group, randomized, single center, prospective, phase IV clinical trial. PARTICIPANTS Sixty-two subjects with PEX and cataract will be sequentially assigned, according to a computer-generated randomization list (1:1), to bromfenac (n = 31) or not (n = 31). INTERVENTION Cataract surgery by means of phacoemulsification and implantation of posterior-chamber intraocular lens will be performed by two experienced ophthalmic surgeons. Standard Arm: only a standard antibiotic and steroid ophthalmic suspension will be given starting the day after the surgery for two weeks, dosed QID for the first week and BID for the second week (dexamethasone 0.1% and tobramycin 0.3% eye drops association). Experimental Arm: eyes will receive bromfenac BID for two weeks starting the day after surgery. Standard post-operative topical antibiotic and steroid will be also given concurrently, dosed QID for the first week and BID for the second week (dexamethasone 0.1% and tobramycin 0.3% eye drops association). Measurements will be carried out at baseline and after one day, 3 days, 1 week and 4 weeks from cataract extraction.

To assess the safety and efficacy of a cohort of patients switched to the dorzolamide/timolol maleate fixed combination because they are insufficiently controlled on latanoprost monotherapy.

This study aims to evaluate the effect of a single session of micropulse laser trabeculoplasty (MLT) on cornea in eyes with primary open glaucoma (POAG) and pseudoexfoliation glaucoma (PEXG).

Glaucoma is the world's the second leading cause of irreversible blindness. The World Health Organization (WHO) estimated the incidence of blindness due to glaucoma to be 4.4 million people worldwide in 2002. Intraocular pressure (IOP) is the sole proven modifiable risk factor for the development and progression of glaucomatous optic neuropathy. Medical therapy is aimed at lowering IOP in order to prevent or slow progression. Exfoliation syndrome (XFS) is the most common identifiable cause of open-angle glaucoma, affecting an estimated 60 to 70 million people worldwide. Approximately two-thirds of patients have disease in only one eye on clinical examination; however, XFS is detectable in the other eye with conjunctival biopsy. XFS is also a systemic disease, with effects on the cardiovascular and cerebrovascular systems. Patients with XFS are twice as likely to convert from ocular hypertension to glaucoma. Glaucoma in XFS is more severe than primary open angle glaucoma. There is greater diurnal IOP fluctuation, greater visual field loss and optic nerve head damage at the time of diagnosis, poorer response to medications, more rapid visual field progression and more frequent need for surgery. Because you meet eligibility criteria for our study, we ask for your consent to participate in the study described below. In brief, you will be taking an investigational drug (AR-12286, rho-kinase Inhibitor) at either 0.5% or 0.7% once a day for 6 months. This drug is currently being tested in patients with primary open-angle glaucoma, but not yet in glaucoma in exfoliation syndrome. Because of the mechanism of glaucoma in XFS and the mechanism of action of rho-kinase inhibitors, there is reason to think it would be more effective in eyes with XFS and glaucoma than in primary open-angle glaucoma (ordinary glaucoma). There will be a baseline and study day 1 visit, week 1 visit, month 1 and 3 visit, week 13 visit, month 6 visit and a week 25 visit; for a total of 7 office visits.

The type of anti-inflammatory medication used post selective laser trabeculoplasty (SLT) may have an impact on the intra-ocular pressure (IOP) lowering effect of SLT. This study will evaluate the IOP lowering effect of SLT following the topical administration of one of the following: prednisolone 1%, ketorolac 0.5% or artificial tears.
