Cost-Effectiveness of Bevacizumab and Ranibizumab for Newly Diagnosed Neovascular Macular Degeneration – Corrected Proof
Purpose: We sought to determine the most cost-effective treatment for patients with newly diagnosed neovascular macular degeneration: monthly or as-needed bevacizumab injections, or monthly or as-needed ranibizumab injections.Design: Cost-effectiveness analysis.Participants: Hypothetical cohort of 80-year-old patients with newly diagnosed neovascular macular degeneration.Methods: Using a mathematical model with a 20-year time horizon, we compared the incremental cost-effectiveness of treating a hypothetical cohort of 80-year-old patients with newly diagnosed neovascular macular degeneration using monthly bevacizumab, as-needed bevacizumab, monthly ranibizumab, or as-needed ranibizumab. Data came from the Comparison of Age-related macular degeneration Treatment Trial (CATT), the Medicare Fee Schedule, and the medical literature.Main Outcome (Read more...)
Proton Therapy for Uveal Melanoma in 43 Juvenile Patients: Long-Term Results – Corrected Proof
Purpose: To examine the metastatic and survival rates, eye retention probability, and the visual outcomes of juvenile patients after proton beam radiotherapy (PBRT) for uveal melanoma (UM).Design: Retrospective case-factor matched control study.Participants and Controls: Forty-three patients younger than 21 years treated with PBRT for UM were compared with 129 matched adult control patients.Methods: Information on patient demographics and clinical characteristics were recorded before and after treatment from patients’ files. The control group was composed of adult patients (>21 years) matched for tumor size (largest tumor diameter, ±2 mm; height, ±2 mm) and anterior margin location (iris, ciliary body, pre-equatorial or (Read more...)
Assessment of Iris Surface Features and Their Relationship with Iris Thickness in Asian Eyes – Corrected Proof
Purpose: To assess iris surface features in Asian eyes and examine their associations with iris thickness measured by anterior segment optical coherence tomography (AS OCT).Design: Cross-sectional study.Participants: We recruited 250 subjects from the Singapore Malay Eye Study.Methods: We obtained standardized slit-lamp photographs and developed a grading system assessing iris crypts (by number and size), furrows (by number and circumferential extent), and color (higher grade denoting darker iris). Vertical and horizontal cross-sections of the anterior chamber were imaged using AS OCT. Intragrader and intergrader agreements in the grading of iris surface were assessed by weighted κ (κw) statistic. Associations of the (Read more...)
Intraocular Pressure in Eyes Receiving Monthly Ranibizumab in 2 Pivotal Age-Related Macular Degeneration Clinical Trials – Corrected Proof
Purpose: To characterize preinjection intraocular pressure (IOP) in eyes receiving monthly ranibizumab versus sham or verteporfin photodynamic therapy (PDT) for age-related macular degeneration (AMD).Design: Post hoc analysis of IOP data from 2 phase 3 clinical trials, the Minimally Classic/Occult Trial of the Anti-VEGF Antibody Ranibizumab in the Treatment of Neovascular AMD (MARINA) and the Anti-VEGF Antibody for the Treatment of Predominantly Classic Choroidal Neovascularization in AMD (ANCHOR) trial.Participants: All safety-evaluable patients who received 1 or more injections of sham or PDT or of ranibizumab and had 1 or more postbaseline IOP measurements recorded for the study eye.Methods: Preinjection IOP measurements (Read more...)
Genes in the High-Density Lipoprotein Metabolic Pathway in Age-Related Macular Degeneration and Polypoidal Choroidal Vasculopathy – Corrected Proof
Purpose: To investigate the associations of genetic variants in the high-density lipoprotein (HDL) metabolism pathway with neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV).Design: Cross-sectional, case-cont…
Diagnostic Performance of Optical Coherence Tomography Ganglion Cell–Inner Plexiform Layer Thickness Measurements in Early Glaucoma – Corrected Proof
Purpose: To evaluate the glaucoma diagnostic performance of ganglion cell inner–plexiform layer (GCIPL) parameters used individually and in combination with retinal nerve fiber layer (RNFL) or optic nerve head (ONH) parameters measured with Cirrus HD…
A Randomized, Controlled Trial of Corneal Collagen Cross-Linking in Progressive Keratoconus: Three-Year Results – Corrected Proof
Purpose: To report the refractive, topographic, and clinical outcomes 3 years after corneal collagen cross-linking (CXL) in eyes with progressive keratoconus.Design: Prospective, randomized controlled trial.Participants: One hundred eyes with progressive keratoconus were randomized into the CXL treatment or control groups.Methods: Cross-linking was performed by instilling riboflavin 0.1% solution containing 20% dextran for 15 minutes before and during the 30 minutes of ultraviolet A irradiation (3 mW/cm2). Follow-up examinations were arranged at 3, 6, 12, 24, and 36 months.Main Outcome Measures: The primary outcome measure was the maximum simulated keratometry value (Kmax). Other outcome measures were uncorrected visual acuity (UCVA; measured (Read more...)
