The effect of hydrocortisone (HC) treatment [high HC dose at Hamburger and Hamilton (HH) 29 and HH 30] on conjunctival papillae number at HH 34. (A) A control no injection (CNI) embryo with a normal ring of papillae. (B) An HC‐injected embryo in which no conjunctival papillae developed. In this particular embryo, the eyelids are also severely reduced. Scale bars: 2 mm. (C,D) Percentages of eyes at HH 34 that have 0–4, 5–8, 9–12 or 13–16 papillae per eye in CNI (C) embryos or after high HC treatment at HH 29 and HH 30 (D).
