Abstract
Myopia is a global public health problem leading to visual impairment and
blinding complications. Myopic foveoschisis (MF)/foveoretinal detachment (FRD)
might be responsible for progressive visual loss in eyes with macular traction
maculopathy (MTM). An assessment of the macular microcirculation might identify
defects that are potentially implicated in subsequent pathological changes. In the
present chapter, macular perfusion in normal eyes was compared with that in highly
myopic eyes with MF/FRD. Vessel density (VD) differed between the groups, and the
superficial area of the foveal avascular zone (FAZ) was significantly larger in the
control groups. Better final visual acuity results were significantly correlated with
fewer structural findings and greater VD (p < 0.05). The central subfoveal thickness
was significantly larger in the control groups and significantly smaller in the surgery
group. These findings suggested a higher incidence of macular perfusional VD
deficiencies and abnormalities in the FAZ area in the highly myopic eyes.
