To report a new way of imaging macular hole surface using adaptive optics (AO).
Sixteen patients presenting a full-thickness macular hole (MH) were imaged before surgery using an adaptive optics retinal camera (RTX-1, Imagine Eyes, Orsay, France). Focus was set on the surface of the retina and centered on the MH. Reproducibility of AO measurements was assessed by 2 independents graders. A morphometric comparison of the MH using AO and SD-OCT (Spectralis, Heidelberg, Germany) was carried out. Finally, the relationship between the area, the horizontal (HD), and the vertical (VD) diameter of the MH and the postoperative visual acuity (VA) was studied.
AO provided highly reproducible measurements (r2=0.97, p< 0.0001 between the 2 readers). The agreement between AO and OCT measurements was also excellent (r2=0.97, p< 0.0001). It appeared that HD was the parameter most strongly correlated to VA (r2=0.47, p=0.01), followed by the surface area (r2=0.32, p=0.05), whereas the shape of the MH(evaluated by the ratio HD/VD) was poorly related to the visual outcome (r2=0.27, p>0.05). The presence and size of cysts observed on AO images corresponded to retinal cysts located in the inner plexiform and outer nuclear layers on cross-sectional OCT scans.
AO allows measurements of the MH surface with unmatched precision. Further studies on the clinical application of AO imaging of MH are warranted.
