(A–C) Transverse plastic sections of 4 dpf larvae heads from wild-type and pard3 morphants show variable degrees of cyclopia but normal lamination. (D–F) Higher magnification of the boxed areas in A–C revealed the photoreceptor outer segments in wild-type retinas (Panel D, arrows), which were missing in pard3 morphants. Morphants with fused eyes also exhibited patchy pigmentation in the RPE (Panel E, arrowheads). (G–H) Transmission electron microscopy of wild-type and pard3 morphant retinas showed truncation of photoreceptor outer segments. ONL, outer nuclear layer; OPL, outer plexiform layer; INL, inner nuclear layer; IPL, inner plexiform layer. Scale bar = 50 µm (A–C); 10 µm (D–F); 1 µm (G–H).
