{Reference Type}: Case Reports {Title}: Internuclear ophthalmoplegia following radial artery cardiac catheterization approach: An unusual presentation. {Author}: Daryabari SH;Mosavi SA;Sharoubandi SH;Zarei H; {Journal}: Saudi J Ophthalmol {Volume}: 38 {Issue}: 1 {Year}: 2024 Jan-Mar 暂无{DOI}: 10.4103/sjopt.sjopt_2_23 {Abstract}: Internuclear ophthalmoplegia (INO) may happen following percutaneous coronary intervention and angiography. However, no reports of INO during radial artery angioplasty were reported yet. We report a rare case in a 47-year-old man presenting with diplopia after radial artery angioplasty. Although the symptoms were resolved after 60 days, diagnosing this obstacle is necessary to reduce the patient and physician's anxiety.
