Purpose : Retinal complications are the most important cause of visual decline in high myopia. The most established classification system to diagnose these lesions is META-PM, but this was developed mainly on Asian eyes. Here, we evaluated the performance of the META-PM classification in European eyes, assessed the relation with visual acuity and investigated potential ethnical differences.

Methods : A total of 451 patients with high myopia (spherical equivalent (SphE) ≤-6 D) from the Dutch MYST study were extensively examined using visual function tests and multimodal imaging. With the META-PM grading system, we analysed the type, extent and location of retinal complications on funduscopic photographs. We computed a complication score based on staphyloma, various myopic macular changes, myopic peripapillary atrophy (MPA), and/or a peripapillary intrachorideal cavitation (score range 0-4). We calculated correlation coefficients between parameters and visual acuity (Pearson and Spearman’s correlation coefficient (rs), for normally distributed and skewed data, respectively), and applied unpaired t- tests to assess differences in visual acuity between complication locations.

Results : The mean age of the participants was 45.8 ± 13.0 years, the percentage men 36.4% and mean SphE was -10.36D ± 3.26. The most frequent lesion was MPA (62.0%) followed by staphyloma (21.4%). For comparison, the prevalence of MPA in Asians was reported to be 81.2% and of staphyloma was 23%. Foveal involvement of the staphyloma was present in 55.1% and was associated with decreased visual acuity (BCVA with vs. without foveal involvement 0.60±0.37 vs 0.85±0.28 (P=1,25E-06)). The occurrence of active CNV or Fuchs spot was rare (0.56% and 1.11% for CNV and Fuchs spot respectively).
A significant correlation was observed between complication score and mean SphE (rs= -0.428, P= 3,36E-21), mean axial length (rs= 0.567, P= 8,03E-39) and age (rs= 0.297, P= 1,76E-10). This was in line with a significant trend (P<0.001) of more complications with lower spherical equivalent, longer axial length and higher age reported in Asians

Conclusions : The META-PM grading system enabled reliable identification and quantification of retinal complications due to myopia in Europeans.The frequency of complications was in line with that of Asians, albeit a slightly lower prevalence of MPA. Awareness of the morbidity of high myopia should be present around the globe.
