Summer 2017

Message from the Chair


August 2017

Dear Glaucoma Section Members,

We are getting ready for Academy 2017 Chicago and another week of great glaucoma lectures, research and events. I first would like to thank the Glaucoma Section Executive Board for their tireless efforts in creating interested and exciting lectures and events, some of which are in collaboration with the Fellows Doing Research (FDR) SIG and the Scientific Program. While each member is incredibly busy with their own practices and individual pursuits, it is their continued efforts that create our Section's stellar lineup of events at each Academy meeting.

This year I would like to highlight a new project, our exhibit hall booth. This will be a great place to see and learn more about the Glaucoma Section and will be open during all exhibit hall hours. Please stop by to introduce yourself, sign up for our google group or learn about getting involved in the Section.

See you in Chicago!

Glaucoma Section Happenings at Academy 2017 Chicago


Come visit the Glaucoma Section at the Exhibit Hall during Academy 2017 Chicago! We will be sponsoring 2 booths at the Exhibit Hall.

Bottoms Up IOP: a research collaboration between the Glaucoma section and Fellows Doing Research (FDR) Sig investigating the relationship between IOP and optic nerve head characteristics in response to inversion. Research subjects will have OCT images taken of the optic nerve, measuring blood pressure measurements and IOP readings while in a seated position. Then they will lay on an inversion bed at a 30-degree angle for 2 minutes, followed by repeat measurements of blood pressure and IOP. Please stop by during exhibit hall hours and participate in this fun and exciting research!

Glaucoma Section Informational Booth: Come learn about the benefits of being in the Glaucoma Section, sign-up to be part of our google group discussions, learn about becoming a Diplomate in the glaucoma section, hear about events planned for Academy 2017 Chicago and even give us suggestions. The booth will be available during Exhibit Hall hours.

We are looking for volunteers to help with both the research booth and the informational booth. If you have any interest in volunteering for the research booth, please email Dr. Lauren Ristin atlaurenristin@gmail.com. If you are interested in volunteering at the Information booth, please email Dr. Jennifer Brown atjenniferbrown0726@gmail.com

Glaucoma Section Symposium Academy 2017 Chicago


MIGS: Emerging Technologies in Glaucoma Surgery

Evolving technologies in the field of micro-invasive glaucoma surgery (MIGS) have set the stage for a shift in treatment approach for qualifying patients with open angle glaucoma. It offers a welcomed new option for patients intolerant to medical management who lack the severity that necessitates the high risks of traditional surgical procedures. Optometrists must be prepared to accurately identify and selectively refer those candidates who would benefit most from this new technology.

Literature Review


Ganglion cell-inner plexiform layer change detected by optical coherence tomography indicates progression in advanced glaucoma
Shin JW, Sung KR et al.
Ophthalmology 2017; 1-9

Review and Commentary By Andrew Sacco, OD, FAAO

This study was retrospective in nature with study participants from one clinic in Seoul, Korea between the years of 2009 and 2016. Detecting progression in glaucoma is one of the challenges we face with this disease. Serial testing of retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer (GCIPL) with OCT can be repeatable, sensitive, and show structural change in these tissues. Also, serial evaluation of RNFL thickness can be predictive of visual field progression.

However, progressive changes in the GCIPL in glaucoma have not been studied comprehensively. Thinning rates of the GCIPL and RNFL were compared in two groups of glaucoma patients- “progressors” and “nonprogressors.” Since many landmark glaucoma trials use VF as a primary outcome, progressors and nonprogressors were determined by VF testing using the Early Manifest Glaucoma Trial (EMGT) linear regression of VF index. 136 patients had macular cube scans utilizing the Guided Progression Analysis (GPA) tool of the Cirrus HD-OCT (Zeiss). Out of 196 eyes, 38.8% (76 eyes) showed progressive GCIPL thinning on GPA. GCIPL change detected by GPA showed sensitivity of 79% and specificity of 74% when used to predict VF change per the EMGT guidelines.

The rate of change of the GCIPL was significantly higher in the progressors than nonprogressors regardless of the severity of the glaucoma, and regardless of severity of the glaucoma, progressive thinning of the GCIPL had a higher probability of VF progression. Due to inter test variability and fluctuation in VF testing in those with advanced disease, VF testing has some limitations. Likewise, RNFL thinning as a determinant of progression is limited by the “floor effect,” in which further loss of tissue in advanced disease is difficult to detect. As the papillomacular bundle and GCIPL is relatively robust, it does not suffer from the floor effect as the RNFL does, is easily tested and is concentrated in the area frequently tested with 24-2 VF analysis, it may represent a better way to predict or monitor glaucoma progression. GCIPL testing is reproducible and doesn’t suffer from artifacts as glaucoma becomes more severe. One must account for age related physiologic loss of GCIPL as the Cirrus HD-OCT does not provide age adjusted results on GPA. Once adjusted for that, it may represent a new biomarker to predict glaucoma progression.
