Figure 2. Clinical features of three individuals from two Chinese pedigrees with CFEOM. The second and third columns document the range of extraocular movement in each eye and the position of the eyes in primary position. Extraocular movement is rated on a scale of 0 to 4, with 0 indicating no movement in that direction and 4 indicating normal movement in that direction. The black dot indicates the position of the pupil within the orbit in primary gaze. SR=superior rectus; IR=inferior rectus; LR=lateral rectus; MR=medial rectus; SO=superior oblique; IO=inferior oblique. The presence of ptosis, aberrant eye movements, forced duction testing, and “chin-up” head position is also noted.
