Fig. 29. Graves disease. Marked lid retraction (A) is evident. Small solid arrow marks vessel loop that indicates intorsion when right eye adducts (C). Small open arrow marks vessel loop that indicates extorsion when right eye abducts (B). Note that abducting eye (B and C) depresses in lateral gaze (? tight inferior rectus). Attempted upward gaze (D) results in minimal convergence and increased lid retraction. Full downgaze (E) is achieved. A misdiagnosis of pinealoma had been made.
