[OCT Article] Comprehensive OU Report for Glaucoma Management Enhances Readability and Patient Education

Written by Nate Lighthizer, OD, FAAO | Oct. 30, 2023

As someone who has been in the industry for many years and is responsible for educating the next generation of optometrists, I know how time-consuming glaucoma management has always been for providers. We must assess and clearly explain challenging findings and diagnoses to patients, the success of which is vital for quality patient care.

In the case below, a 62-year-old male presented with advanced/severe POAG (based on visual field criteria). The OCT shows severe retinal nerve fiber layer (RNFL) and ganglion cell damage OD. The radial peripapillary capillary (RPC) is also thin.

These issues may be a combination of glaucoma and an old ischemic optic neuropathy, especially considering the overall thinning of the RNFL, and the mild pallor of the neuroretinal rim that was also noted in the right eye. This report highlights a few things:

  • Measurements like these help to stage the severity of structural defects at a glance, allowing providers to review inter- and intra-eye symmetry and spend less time reviewing multiple reports to make an informed assessment while spending more time with patients.
  • The outer columns for each eye show the deviation map with Pixel x Pixel analysis where the thickness has between a 5% yellow and 1% red chance of being normal. The thickness map shows the loss of the superior and inferior bundle. The RNFL numbers from the 100μ wide ring at 3.45 show
    corresponding loss, a larger C/D ratio and significant vessel density loss in both the superior and inferior hemispheres.
  • The center column gives a tabular format of the results and provides detailed inter- and intra-eye comparison values for the parameters.

This comprehensive report not only lays out complex data for the physician in a readable manner but also enables me to show my patient his left eye and say, “This is fairly normal and what it should look like, and here is the damage we are seeing in your right eye.” These capabilities are fundamentally impactful to patients understanding their diagnosis and may increase their compliance with treatment and follow up recommendations.
