Fourier-domain optical coherence tomography and time-domain OCT have both showed that the retinal nerve fiber layer is significantly thinner in glaucomatous eyes.

An anti-platelet-derived growth factor aptamer is safe and well-tolerated when used in combination with anti-vascular endothelial growth factor therapy in patients with neovascular age-related macular degeneration.

Choroidal thinning is not a feature of glaucoma nor does choroidal thickness correlate with retinal nerve fiber layer thickness, according to new study findings.

Eyes categorized as having keratoconus based on corneal topography and subsequently determined to be non-keratoconic by epithelial thickness profile criteria demonstrate good refractive stability after LASIK during up to 2 years of follow-up.

A user-friendly diagnostic ultrasound device offers a range of features that makes it a valuable instrument for anterior and posterior ophthalmic imaging both for clinical use and for teaching applications.

Studies conducted with waveform data obtained using a non-contact applanation tonometer show that this information pertaining to corneal biomechanical properties may have value in helping to identify early-stage compromised corneas.

"For sight: the future of eye and vision research" is the theme of the 2010 meeting of the Association for Research in Vision in Ophthalmology.

An intracorneal inlay for the treatment of presbyopia uses the pinhole effect to increase depth of focus by selecting for the central light ray and minimizing refraction.

Preliminary results from a phase 1 safety and tolerability study show no dose-limiting toxicity so far in patients treated with intravitreal injections of volociximab in combination with anti-VEGF therapy for neovascular age-related macular degeneration.

University of Iowa's Department of Ophthalmology and Visual Sciences has long developed a reputation for educating its residents in a nurturing and supportive environment.

Optic atrophy is itself not a diagnosis, but a stepping stone for further work-up.

Results of the 2009 International Society of Refractive Surgery survey examining refractive surgery practice patterns in the United States show total surgical volume decreased while surgeons are continuing to embrace new techniques and technologies that can afford safer, more predictable outcomes.

Senior ophthalmologists with years of surgical experience have performed thousands of cataract surgeries and often know what they want from an ophthalmic viscosurgical device.

An excimer laser offers a number of features that collectively contribute to outstanding outcomes when using this platform to perform LASIK for a range of refractive errors.

Given the choice, who wouldn't rather wear premium frames?

Results from 3 years of follow-up in the phase II clinical trial investigating an angle-supported phakic IOL for the treatment of moderate to high myopia indicate this anterior chamber implant provides excellent visual acuity and is associated with accurate predictability of refraction and promising safety.

The safety and efficacy of cataract removal using torsional ultrasound with a proprietary handpiece and phacoemulsification system have been raised to a higher level by a recent software upgrade, according to one expert.
