Abstract

44-year-old hypertensive male patient presented to us with complains of drooping of RE upper lid and deviation of RE without H/O trauma, on examination RE pupil sparing 3rd nerve palsy was noted along with contralateral abnormally dilated pupil. Anisocoria present (left pupil dia> right pupil dia). Direct and consensual light reflex and near reflex present in RE but absent in LE. EOM in LE is normal. To conclude this case, demonstrate that it is possible to damage the fibres destined for pupillomotor function without affecting the extraocular muscles and vice versa also possible as in pupil sparing 3rd nerve palsy.
