The Asia Primary Tube Versus Trab (TVT) Study (TVT)
研究概览
详细说明
The objective of the Asia Primary Tube versus Trab (TVT) study is to compare the efficacy and safety of placement of an Ahmed Glaucoma Implant (AGI) (New World Medical Inc., Rancho Cucamonga, CA, USA) against trabeculectomy with mitomycin C in patients with uncontrolled glaucoma, who may or may not have had previous clear corneal cataract surgery with intraocular lens implantation, over 5 years. Outcome discrimination between the two treatment groups will be made using following parameters:
- Intraocular pressure
- Need for supplemental medical therapy
- Incidence of short and long term surgical complications and need for re-operation.
- Visual function (Visual acuity and Visual field)
Hypothesis: Glaucoma drainage implants have better surgical outcomes in terms of IOP lowering efficacy compared to trabeculectomy with mitomycin-C over 5 years in Asian patients with medically uncontrolled glaucoma.
