76 | EYEWORLD | SEPTEMBER 2019 G UCOMA Contact information Sheybani: sheybaniar@wustl.edu by Liz Hillman EyeWorld Senior Staff Writer Outcome of two second generation trabecular bypass implants combined with cataract surgery in cases of medically controlled glaucoma Sebastien Gagne, MD Dr. Sheybani said this study looked at the iStent inject (Glaukos) in medically controlled glauco- ma patients who were having cataract surgery. Dr. Sheybani said this is interesting because most data shows patients with pressures that are out of control at baseline followed by surgi- cal treatment. The study showed a mean 16.4 mm Hg preoperatively and 15.6 mm Hg postop day 1. While this IOP dip might be modest, Dr. T he Best of ASCRS 2019 is a general session at the ASCRS ASOA Annu- al Meeting where members of the EyeWorld Editorial Board select what they think were the best papers in different categories from the meeting. They chose from the papers that were awarded Best Paper of Session in each individ- ual paper session throughout the meeting and explain why they made their selections. Here we recap the selected papers in the Glaucoma category and why Arsham Sheyba- ni, MD, a member of the EyeWorld Glaucoma Editorial Board, thought they were noteworthy. "I wanted to look at how we split it up between some of these treatment paradigms, and I want to start with the least invasive then go most invasive in terms of these papers," Dr. Sheybani said, introducing his first topic. Intraocular pressure response to negative pressure applied to the anterior periocular microenvironment Russel Swan, MD, John Berdahl, MD, Ike Ahmed, MD, Richard Lindstrom, MD, Nathan Radcliffe, MD, Vance Thompson, MD, and Michael Greenwood, MD Dr. Sheybani described this paper as taking a "different approach to how we lower intraoc- ular pressure." The study looked at the effect of ocular goggles (Balance Goggles, Equinox) that lower intraocular pressure by decreasing the atmospheric pressure around the eye. Pressure was measured by use of a pneumotonometer within a minute of removing the goggles and via an excursion port where the pneumotonom- eter could be used to measure pressure while wearing the goggles. All 51 patients in the study showed pressure lowering through use of the goggles. "Here's a novel way to lower pressure that was very low on the invasiveness level," Dr. Sheybani said. "This was just an hour of treat- ment, but I think it is paradigm shifting."
