Is it Myopia or Glaucoma? Clinical Tools to Identify the Disease
Final Report Abstract
This project demonstrated that the anatomy of glaucoma eyes with axial myopia differed significantly from glaucoma eyes without axial myopia. Compared to glaucoma eyes without high myopia, axial highly myopic eyes: had a smaller BMO ovality index (were more oval) - had larger BMO tilt angle - had no differences in BMO rotation angle - had no differences in global peripapillary RNFL and BMO-MRW thickness, except for the temporal and superonasal sector, respectively - had a lower peripapillary and macular vessel density - had thinner peripapillary and macular choroidal thickness - had similar global and sectoral GCIPL and GCC thickness values - had a higher rate of BMO segmentation inaccuracy rates. Furthermore, automatic OCT scan based BMO ovality index and rotation angle measurements can not be compared to optic disc photograph clinical disk margin based measurements of those parameters. This project contributed important data to objectively characterize morphological characteristics of glaucomatous optic discs with and without axial myopia. The results are useful to evaluate parameters that might be useful to diagnose and monitor glaucoma in myopic eyes. Because ganglion cell-related macular thickness measurements were strongly associated with VFMD but did not vary with axial length, GCIPL and GCC showed promise for detecting glaucoma in myopic eyes. Furthermore, our results suggest that peripapillary RNFL and BMO-MRW glaucoma measurements in highly myopic eyes should be interpreted with caution, as the pattern varies with axial length and OCT scans need to be evaluated for BMO segmentation inaccuracies. Inaccurate BMO segmentation impacts BMO-MRW measurements, but also the peripapillary RNFL measurements based on OCT radial scans and may lead to false positive glaucoma diagnosis in highly myopic eyes. Future work including healthy high myopic eyes is underway and promises identification of the most appropriate diagnostic tools to differentiate between myopic eyes with and without glaucoma.
