(18) Scleral depression with binocular indirect ophthalmoscopy will be easier to learn if the examiner observes the patient's pupillary reflex through the ophthalmoscope without looking through the hand-held condensing lens.
(19) Binocular single vision was restored after buckle removal and strabismus surgery in three further patients (20%), one requiring a prism in addition.
(20) The reduction was much smaller in humans with impaired binocular vision, at least for the dominant eye.
