Active clinical trials for "Glaucoma"

During the glaucomatous disease process, subpopulations of cells may be dead, damaged or healthy. Visual function changes could be observed due to a recovering of the suffering ganglion cells after the intraocular pressure reduction. This study aims at evaluating the correlation between intraocular pressure reduction and visual function changes in glaucoma patients after using antiglaucoma medications.

Trabeculectomy with mitomycin C remains the standard surgery for glaucoma. This surgery involves creating a door in the eye wall in order to improve fluid outflow and decrease intraocular pressure. However, success rates range from 70% to 90% depending on the criteria used and tend to decrease with time. The failure of the surgery is associated with inflammation, new blood vessel formation and scarring which can cause closure of the door. Molecules which inhibit new blood vessel formation such as inhibitors of vascular endothelial growth factor have been used successfully to decrease scarring in animal eyes where little doors were created and significantly improve survival. Furthermore, they have shown promise when used during trabeculectomy. Ranibizumab, a vascular endothelial growth factor, has also been used safely in intraocular surgery to treat other diseases which involve new blood vessel formation such as macular degeneration and diabetes. The investigators hypothesize that ranibizumab may decrease the failure rate of trabeculectomy with mitomycin C by decreasing scarring. The aim of the study is to evaluate the difference in failure rates and bleb morphology at one year post-operatively in eyes having undergone sub-conjunctival injections of ranibizumab in addition to primary trabeculectomy with mitomycin C compared to eyes having undergone trabeculectomy with mitomycin C alone.

To determine the stability of diurnal intraocular pressure in eyes with glaucoma treated with Cosopt

In this randomized clinical trial we compare trabeculectomy with mitomycin-C (T+MMC) and Ahmed glaucoma implant (AGI) in treatment of aphakic glaucoma in children under 16 years of age.Complete and qualified success were defined as 5≤IOP≤21mmHg without and with medication respectively and we came to this point that; T+MMC and AGI are comparable in terms of success rate and complications in pediatric aphakic glaucoma.

To demonstrate the statistical non inferiority of the combination of latanoprost and timolol given in the evening time once a day vs the combination of dorzamalide and timolol twice a day based on intraocular pressure measurements at 8 AM, 12 noon & 4 PM during a 12 week treatment.

Eligible Glaucoma patients will undergo pre-surgery examination including: medicines list, blood tests and ECG. On surgery day: intraocular pressure (IOP) will be measured. Then a sub-conjunctival injection of Mitomycin C will be administered . The Minimally Invasive Micro Sclerostomy (MIMS) procedure is designed to create a drainage channel at the sclera-corneal junction by penetrating through the wall [scleral tissue] . MIMS procedure may be combined with cataract surgery. Patients will be followed up to 52 weeks post operation.

This study will examine the visual outcomes of subjects undergoing cataract surgery and minimally invasive glaucoma surgery with the implantation of a trifocal intraocular lens.

Purpose: To investigate intravitreal aflibercept (IVA) injection as an adjunctive treatment to trabeculectomy with mitomycin C (TMC) and panretinal photocoagulation (PRP) for neovascular glaucoma (NVG). Setting: Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand Study design: Prospective interventional case series Methods: PRP and IVA (2 mg/0.05 ml) injection were given, and TMC was performed within 2 weeks after IVA. Additional PRP, laser suture lysis, subconjunctival 5-fluorouracil injection, and bleb needling were performed after TMC if indicated. Best-collected visual acuity (BCVA), intraocular pressure (IOP), surgical complications, and number of anti-glaucoma medications were collected.

There is growing awareness that environmental factors, behaviors and diet are intimately related to patient health and may play a role in the pathogenesis and progression of glaucoma. Evidence from recent years has shown that some behaviors and environmental factors can affect the intraocular pressure, the primary risk factor for glaucoma. This study aims to investigate whether simple and common lifestyle inteventions such as sleeping with a head elevation, a high fiber diet, moderate aerobic exercise and moderation in caffeine intake could affect intraocular pressure and other outcomes.

TJO-002 or Acitve Control was administered on primary open-angle glaucoma or ocular hypertension patients for 12 weeks. This clinical trial study has hypothesize TJO-002 administration groups are not inferior to Active control administration groups.
