Background: To report the safety and efficacy of Ex-PRESS(TM) miniature glaucoma implant under a scleral flap in patients with previous ocular surgeries.
Design: Retrospective, non-comparative case series from a tertiary care hospital.
Participants: Patients with previous cataract or failed glaucoma surgeries who had undergone implantation of the Ex-PRESS(TM) miniature glaucoma implant (R-50 and T-50), under a scleral flap, with a minimum of 1-year postoperative follow up.
Objective: To determine which aspects of vision most influence the ability of patients with glaucoma to function.
Methods: A total of 192 patients with a full range of glaucomatous visual loss were selected from the Glaucoma Service of Wills Eye Institute. Patients were evaluated clinically with standard visual assessments: visual acuity, contrast sensitivity, visual field, stereopsis, the Disc Damage Likelihood Scale, and intraocular pressure.
Purpose: To determine the relationships among three methods of assessing visual loss caused by glaucoma: (1) standard clinical tests of vision, (2) self-reported quality of life, and (3) the ability to perform activities of daily living.
Methods: One hundred and ninety two glaucoma patients with a full range of glaucomatous visual loss were selected from the Glaucoma Service of Wills Eye Institute. Subjects were evaluated clinically by visual acuity, contrast sensitivity, visual field, stereopsis, the Disc Damage Likelihood Scale, and intraocular pressure.
Purpose: To validate a third-generation performance-based measure of visual function titled "Assessment of Disability Related to Vision" (ADREV) in a study population of patients with diabetic retinopathy.
Design: Prospective, cross-sectional study.
Methods: Patients with nonproliferative or proliferative diabetic retinopathy, free from ocular comorbidity, were recruited from a single institute and completed the ADREV, the 25-Item National Eye Institute Visual Functioning Questionnaire (VFQ-25), and a clinical ophthalmic examination.
Purpose: To describe study protocol and baseline characteristics of initial subjects.
Methods: Prospective study of 194 glaucoma patients. After informed consent, patients were evaluated using a third-generation, performance-based measure, Assessment of Disability Related to Vision (ADREV), nine tasks to simulate daily living activities; including: reading in reduced illumination, recognizing facial expression, detecting motion, recognizing street signs, locating objects, ambulating, placing pegs into different sized holes, telephoning, and matching socks.
