Methods
This study consisted of 2 phases: first, a consensus meeting to develop a classification system for myopic maculopathy; and second, assessment of the inter- and intraobserver agreement in applying the classification system to 100 selected fundus photographs of eyes with pathologic myopia, defined as having signs of myopic maculopathy in eyes with a myopic refractive error of greater than −8.0 diopters. This research adhered to the tenets of the Declaration of Helsinki, and the classification of
Formulation of Proposed Classification for Myopic Maculopathy and Related Lesions
We first identified 3 papers proposing classification for myopic maculopathy in detail. The first paper was by Curtin and Karlin9 and proposed 5 fundus changes associated with increased axial length of the eye, namely, optic nerve crescent, chorioretinal atrophy, central pigment spot (Fuchs spot), lacquer cracks, and posterior staphyloma. This classification has a limitation in that it does not cover all the myopic maculopathy lesions (eg, CNV), nor does it provide detailed differentiation
Discussion
There has been no widely used universal classification system of myopic maculopathy that allowed a reliable comparison of the prevalence, incidence, and patterns of these lesions between studies. We propose a simplified, uniform classification system for use in future studies on myopic maculopathy. We incorporated the results of previously published studies and adopted the concepts and classifications of these studies in developing this new classification of myopic maculopathy. We have also
