Intracorneal ring segments may not halt progressive keratoconus in long term

WARSAW, Poland — Implantation of intracorneal ring segments in young keratoconus patients may not be able to stop the progressive nature of the disease, even though it may provided a significant short-term improvement in visual, refractive and topographic status, according to one surgeon.”Several studies have shown the efficacy of this procedure in improving [visual acuity] and flattening the central cornea. However, there is no scientific data to support that corneal ring segment implantation can halt the progressive nature of the disease,” Alfredo Vega-Estrada, MD, said at the winter meeting of (Read more...)

Agreement of Flicker Chronoscopy for Structural Glaucomatous Progression Detection and Factors Associated With Progression – Corrected Proof

Purpose: To evaluate agreement of flicker chronoscopy for structural glaucomatous progression detection and factors associated with progression.Design: Retrospective cohort study.Methods: Two glaucoma fellowship–trained ophthalmologists, masked to temporal sequence, independently graded serial flicker chronoscopy images from 1 eye of a cohort of glaucoma patients for features of structural progression. Agreement between graders was determined, as was accuracy for determining the temporal order of images. After adjudication, simple and multiple logistic models were constructed to determine baseline variables associated with increased odds of progression.Results: Fifty of 103 included eyes/patients (48.5%) had at least 1 sign of structural progression. Temporal sequence was incorrectly (Read more...)
