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?

Even though 90% of our toric IOL cases should be within 0.5 D of residual astigmatism, there will be cases in which the outcome is intolerable for the patient and something must be done. The following discussion explains the proper management.
