Индекс растяжения глазного дна: основанный на центилях ретинальный показатель миопии

Fundus Stretch Index: A Centile-Based Retinal Measure of Myopia.

While increasing myopia is generally accompanied by retinal imaging changes suggestive of a progressively more stretched appearance (e.g., less tortuous and less densely branched vessels),¹, ², ³ some fundi appear far more or far less stretched than would be expected for their degree of myopia. Such discrepancies are partly attributable to the limitation of conventional measures of myopia, which focus on the axial dimension of the eye (visual axis), to describe what is fundamentally a three-dimensional process: ocular growth.⁴ Two eyes may have identical spherical equivalent refraction (SER) yet differ markedly in their posterior segment shape, giving rise to different off-axis retinal morphology.⁴
