Abstract:
Thinning and atrophy of sclerotic tissues play an important role in the development of high myopia. High myopic eyes had the thickest sclera at the posterior pole and the thinnest sclera at the equator. Most clinical studies found that scleral thickness was negatively correlative with the axial length. Patients complicated with posterior staphyloma had even thinner sclera, and its height was negatively related with the scleral thickness. At present, the main measurement methods for scleral thickness of high myopic eyes include histological measurement, enhanced depth imaging optical coherence tomography (OCT), and swept-source OCT. Following the development of OCT technique, it gradually becomes feasible to carry out studies on sclera thickness in mildly and moderately myopic populations, which is helpful to illuminate the mechanism of action of sclera on the onset and progression of high myopia.
