Case Report:
A case is presented of a 63-year-old man who suffered a unilateral isolated trochlear nerve palsy with vertical diplopia following an elective radial coronary angiography and percutaneous coronary intervention, which resolved spontaneously within 2 months.
Discussion:
Ophthalmoplegia following coronary percutaneous angioplasty is rare. Only internuclear ophthalmoplegia, III and VI cranial nerve palsy have been previously reported following percutaneous angioplasty. This is the first reported case of unilateral isolated trochlear nerve ophthalmoplegia following this procedure.
