To investigate the incidence and risk of myopic traction maculopathy including epiretinal membrane traction, foveoschisis, macular retinoschisis and posterior detachment without macular hole in highly myopia eyes.
We prospectively recruited patient with high myopia (spherical equivalence less than -6D or axil length longer than 26.5 mm) from our outpatient department. Subjective or objective refraction, complete ocular examination, fundus photography, A-scan ultrasound biometry, and optical coherence tomography (OCT) were performed to detect the incidence and features of myopic traction maculopathy.
There were 124 eyes of 69 patients included in this study. The degree of myopia ranged from -6 to -27 spherical equivalents (mean -11.45D). The mean axial length was 28.85 +/- 1.94 mm. Detection of myopic traction maculopathy was 8%(10/124). Foveoschisis and macular retinoschisis were the most frequent form of myopic traction maculopathy (70%). Factors of Age older than 50 years old, higher myopia diopter (>=-10D) and posterior staphyloma were significant associated with myopic traction maculopathy (P=0.025, 0.041 and <0.001, respectively)
Older age with the presence of posterior staphyloma in more highly myopic eyes might generate a form of traction maculopathy unique to myopia. Myopic traction maculopathy could be easily detected by OCT and results a separate cause of visual loss.
