Spontaneous resolution of foveal detachment in traction maculopathy in high myopia unrelated to posterior vitreous detachment

BACKGROUND Foveal detachment associated with foveoschisis usually takes a progressive course, and is associated with a poor visual outcome. The purpose of this study was to report the spontaneous resolution of foveal detachment in patients with myopic traction maculopathy without posterior vitreous detachment. METHODS A retrospective study involving eight cases of high myopia with foveoschisis and foveal detachment in which the subfoveal fluid had spontaneously resolved. The clinical characteristics and optical coherence tomography (OCT) findings were described. RESULTS All cases involved predominant schisis in the outer retina, with six showing internal limiting membrane detachment. The average central foveal thickness was 445.1 μm, and the average foveal detachment height was 271.5 μm. None of the cases involved traction of the vitreomacular interface or posterior vitreous detachment (PVD), either before or after the resolution of foveal detachment. In seven cases, the mean best-corrected visual acuity improved after foveal reattachment. CONCLUSIONS Spontaneous reattachment not associated with PVD can occur in cases of high myopic traction maculopathy, especially in those without obvious vitreomacular traction.
