If the diplopia disappears on covering either eye the diplopia is binocular. If diplopia is persistent or worsens if one of the eyes is occluded then it’s uniocular diplopia of the other eye. Uniocular diplopia Any corneal surface problems like tear film abnormalities, uncorrected astigmatism, early stages of cataract, subluxated lens, or early macular issues can cause uniocular diplopia. A simple pinhole test can confirm the same. The management of this is to address the cause. Binocular diplopia Binocular diplopia is double vision typically arising as a result of strabismus or
