Flat-mount preparation of the ILMs for AQP4 immunofluorescence. (a) Low-intensity AQP4-positive reactions are uniformly scattered and evenly distributed on the ILM of a patient of the control group (arrow). (b) No AQP4-positive reactions are detected on the ILM of a patient of the negative control group. (c) Compared with the control group, higher intensity AQP4-positive reactions are detected and more densely distributed in the no DME group (arrow); (d) In the DME group, AQP4-positive reactions are most abundant, irregularly gather and form clusters (arrow).
