Comparison of the Effect of Ranibizumab and Verteporfin for Polypoidal Choroidal Vasculopathy: 12-Month LAPTOP Study Results – Corrected Proof

Purpose: To compare the effect of photodynamic therapy (PDT) and intravitreal ranibizumab in patients with polypoidal choroidal vasculopathy (PCV).Design: Randomized clinical trial.Methods: setting: Multicenter. study population: Total of 93 patients with treatment-naïve PCV. intervention: Patients were randomized to 2 arms. Patients in the PDT arm underwent a single session of PDT with verteporfin, and patients in the ranibizumab arm received 3 monthly ranibizumab injections at baseline. Additional treatment was performed as needed in each arm. main outcome measures: Primary outcome measurement was the proportion of patients gaining or losing more than 0.2 logarithm of minimal angle of resolution (logMAR) units from (Read more...)

Age- and Hypertension-Dependent Changes in Retinal Vessel Diameter and Wall Thickness: An Optical Coherence Tomography Study – Corrected Proof

Purpose: To validate and evaluate the reliability of retinal vessel diameter measurements by optical coherence tomography (OCT). The effects of age and hypertension on vessel diameter were also examined.Design: Prospective, cross-sectional study.Methods: Two hundred thirty-eight eyes (238 subjects) with no ocular disease were included. Hypertension was present in 106 subjects and absent in 132 subjects. Spectralis HRA+OCT was used to scan a circular region around the optic disc. Outer and inner diameters of the 4 largest retinal arteries and veins were measured using OCT vascular wall reflections, and vessel wall thickness was calculated.Results: Intervisit, interexaminer, and interevaluator intraclass correlation coefficients (Read more...)
