Five-Year Cumulative Incidence and Progression of Myopic Maculopathy in a German Population

To investigate the 5-year cumulative incidence and progression of myopic maculopathy in the general population in Germany and to analyze potential risk factors.The Gutenberg Health Study (GHS) is a population-based cohort study including 15 010 participants aged 35 to 74 years at baseline.A total of 494 eyes of 323 participants (mean age, 50.2 ± 9.2 years; median, -7.25 diopters [D] myopic refractive error) without myopic maculopathy at baseline and 34 eyes of 27 subjects (mean age, 56.7 ± 9.1 years; median, -8.75 D myopic refractive error) with myopic maculopathy met the inclusion conditions, phakic eyes with spherical equivalent ≤-6 D (baseline), and had gradable fundus photographs at baseline and 5-year follow-up.Myopic maculopathy incidence and progression were assessed by grading of fundus photographs according to a recent international photographic classification system (META-PM). Multivariable logistic regression analysis was used to assess risk factors for progression of myopic maculopathy.Estimates for incidence and progression of myopic maculopathy.The 5-year cumulative incidence of myopic maculopathy was 0.3% (95% confidence interval [CI], 0.02-1.99; n = 1). Progression occurred in 17 of 34 eyes (50%) with prior myopic maculopathy over 5 years with 4 changes in category. The most common types of progression were enlargement of diffuse and patchy chorioretinal atrophy; a new pathology was present in 8 eyes. Higher intraocular pressure (IOP) (odds ratio [OR], 1.62; 95% CI, 1.51-1.59; P = 0.035) was associated with progression of myopic maculopathy. Female gender (OR, 5.54; 95% CI, 0.93-32.92; P = 0.060) and higher myopic refractive error (OR, 1.62 per diopter; 95% CI, 0.99-1.49; P = 0.063) showed a tendency toward progression.Incidence of myopic maculopathy is rare in highly myopic eyes in the general population aged 35 to 74 years in Germany. Progression of myopic maculopathy in the German population occurred in 50% of highly myopic eyes. We presented population-based 5-year follow-up data on incidence and progression of myopic maculopathy in Europe.
