Analysis of retinal nerve fiber layer thickness maps created with optical coherence tomography enabled the detection of topographic changes associated with glaucoma progression, a study found.

Optic nerve head characteristics are significantly different between patients with non-glaucomatous keratoconus and healthy control subjects, but retinal nerve fiber layer thickness measurements are more comparable, according to a study.

Carmen A. Puliafito, MD, MBA, OSN Retina/Vitreous Section Editor and dean of the Keck School of Medicine of USC, received the 2012 António Champalimaud Vision Award for the invention and development of optical coherence tomography.

IOL power calculations based on Fourier-domain optical coherence tomography measurements proved highly predictable in eyes with previous myopic laser vision correction, a study found.

Clinicians should factor higher-order aberrations and posterior corneal curvature into IOL power calculations, a lecturer said.

MILAN, Italy — The Hoya iTrace Surgical Workstation is capable of processing and providing a variety of information to cataract and refractive surgeons, helping their clinical decision-making process.

Nodular scleritis presents with acute nodular elevation of the sclera with inflammation. We used high-speed anterior segment optical coherence tomography of 1310 nm wavelength for evaluation of the scleral disease.

Optical coherence tomography has moved from being a tool primarily utilized by the retina subspecialist to one increasingly present in the comprehensive ophthalmologist’s office.

KIAWAH ISLAND, S.C. — Ophthalmology residents at the Storm Eye Institute at the Medical University of South Carolina have developed an adapter that can allow an iPhone to work as an improvised slit lamp, which has been used to help residents deliver slit lamp-quality images instantaneously at little expense, according to a speaker here.

In the two decades since its invention, optical coherence tomography has enabled increasingly rapid and detailed visualization of many eye structures, especially the posterior segment. OCT is particularly effective in identifying retinal morphology that explains disease pathogenesis and heralds disease progression. In addition, it works well for following the anatomic changes that can occur with treatment of macular disease states.
