7 Clinical Trials for Various Conditions
This 52 week study will assess the use of intravitreal aflibercept injections in patients with neovascular glaucoma (NVG) compared to standard of care panretinal photocoagulation. The investigators hypothesize that the neovascularization of the iris and angle present in neovascular glaucoma will resolve more quickly in eye treated with intravitreal aflibercept injection alone and result in increased comfort and preservation of visual field as compared to current standard of care utilizing pan-retinal photocoagulation. The advantages to intravitreal aflibercept injection use could include resolution of NVI/NVA (neovascularization of the iris/neovascularization of the angle) leading to quicker pain relief and quicker lowering of IOP (intraocular pressure).
This study will determine the effectiveness of Mitomycin-C use in the glaucoma surgery Ahmed valve implantation. Approximately 100 patients will be enrolled, with half receiving the Mitomycin-C treatment and the other half receiving placebo treatment.
Clinical Retina research studies often collect aqueous samples in hopes of estimating levels of drug or cytokines in the vitreous. Little is known about how well vitreous and aqueous correlate. This study will collect vitreous and aqueous samples at the same time to evaluate and compare drug and cytokine levels. The overall objective of this study is to evaluate the molecular concentration of growth factors, cytokines and chemokines in human aqueous humor and vitreous samples collected from individuals undergoing pars plana vitrectomy for tractional retinal detachment secondary to proliferative diabetic retinopathy, exudative or tractional retinal detachment secondary to macular degeneration, macular hole or neovascular glaucoma.
The investigators hypothesize that KeraSys is a safe as Tutoplast to cover the tube of the Molteno 3 glaucoma drainage device during surgery
The purpose of this study is to evaluate and compare the clinical outcomes after implantation of the porous plate (polyethylene) (Model M4) Ahmed Glaucoma Valve with the silicone plate Ahmed Glaucoma Valve (Model FP7) in participants with refractory glaucoma.
The investigators hypothesize that intracameral Triesence during glaucoma surgery will provide lower intraocular pressure through better control of ocular inflammation, thus leading to a more successful filtering procedure.
The purpose of the study is to investigate the safety and tolerability of the anti-VEGF (vascular endothelial cell growth factor) treatment, ranibizumab, in combination with proton beam irradiation for the treatment of choroidal melanoma by determining the incidence and severity of ocular adverse events. Systemic adverse events will also be evaluated. A secondary objective is to assess the efficacy of ranibizumab in reducing ocular complications that can occur after irradiation.
