The National Eye Institute Visual Function Question naire-25 , Impact of Vision Impairment and Treatment Satisfaction Survey-Intraocular Pressure had the highest number of positive ratings in the content validity assessment .
Conclusion This study provides a descriptive catalogue of vision-specific PRO instruments , to inform the choice of an appropriate measure of patient-reported outcomes in a glaucoma context
Purpose To identify  vision Patient-Reported Outcomes instruments relevant to glaucoma and assess their content validity .
The tube versus trabeculectomy study: design and baseline characteristics of study patients.
PURPOSE The Tube Versus Trabeculectomy ( TVT ) Study will compare the safety and efficacy of nonvalved tube shunt surgery to trabeculectomy with mitomycin C in patients with previous intraocular surgery . DESIGN Multicenter r and omized clinical trial . METHODS SETTING 17 Clinical Centers . STUDY POPULATION Patients 18 to 85 years of age who have undergone previous trabeculectomy , cataract extraction with intraocular lens implantation , or both and have inadequately controlled glaucoma with intraocular pressure ( IOP ) > or=18 mm Hg and < or=40 mm Hg on tolerated medical therapy . INTERVENTIONS Study patients were r and omized to undergo placement of a 350-mm(2 ) Baerveldt glaucoma implant or trabeculectomy with mitomycin C ( 0.4 mg/ml for 4 minutes ) . MAIN OUTCOME MEASURES IOP , complication rates , visual acuity , visual field , quality of life , reoperations for glaucoma , and need for supplemental medical therapy . RESULTS A total of 212 patients were enrolled between October 1999 and April 2004 . The age of the study population was 71.0 + /- 10.4 years ( mean + /- SD ) , and 53 % were women . The baseline  IOP  was 25.3 + /- 5.3 mm Hg ( mean + /- SD ) . There were no significant differences in the demographic and ocular characteristics between the 2 treatment groups . CONCLUSIONS Practice patterns vary in the surgical management of glaucoma , and there are differing opinions among glaucoma surgeons regarding the preferred surgical approach in patients who have undergone previous cataract extraction and /or failed filtering surgery . Forthcoming data from the TVT Study should provide valuable information comparing two surgical procedures commonly used in this patient population
