All infants with suspected congenital Zika syndrome have been found to have vision impairment, S. Grace Prakalapakorn, MD, PhD, assistant professor of ophthalmology and pediatrics at Duke University, said during the Zika Virus and Your Eyes webinar hosted by Prevent Blindness.

Deciding the refractive target and IOL for cataract surgery is a daunting task for both the surgeon and patient. The first two questions that must be answered are: Do you mind wearing glasses for intermediate and near tasks, and would the presence of halos and glare be acceptable in exchange for reducing your dependence on glasses?

The annual Women in Ophthalmology Summer Symposium will take place in San Diego from Aug. 10 to 13 with a restructured format, new content and more networking opportunities, meeting chair Lisa Nijm, MD, JD, told Healio.com/OSN.

Binocular games and movies that rebalance contrast are a promising option for treating amblyopia, according to research from Krista R. Kelly, PhD, and colleagues presented at the Association for Research in Vision and Ophthalmology.

Researchers found that a significant decline in reading efficiency was associated with reduced visual acuity.

What is the farthest a human can see? What is the best recorded visual acuity? How far is the horizon?

The eye is far more complex and variable than we previously thought. As with all biological systems, there are inconspicuous, obscure measurable differences that are not always evident. Many ophthalmologists and the public at large think of the eyeball as being shaped like a basketball with set, regular curved surfaces that should perfectly refract and conduct light rays. In astigmatism, the eye may be described as resembling an American football. Methods of measurement and evaluation have grown more sophisticated, revealing the eye’s nuances in structural variation and processing that make our visual world function in the face of such tremendous complexity.

Erica L. Dixon and Arthur G. Shapiro used a series of experiments to show how the 2015 dress phenomenon may be explained by variations in a simple spatial filter that extracts relevant information from the environment.

Multifocal IOLs have slightly less than 5% of the market in the U.S., which has been constant for the past 5 years. Yet, there are practices that implant in excess of 90% of their cataract surgery patients with multifocal IOLs. How is this disparity possible?
