A 27-year-old man presented with the complaint that his right eye turned in slightly and that it appeared lower. He said he had poor vision in his right eye for as long as he can remember. The strabismus got worse, he thought, after an auto accident three years ago. He is in good health otherwise. Examination revealed 20 prism diopters (PD) of right esotropia and 10 PD of right hypotropia. Vision was OD hand motions and OS 20/30. Refraction was OD 0.25 –1.50 x 10 and OS -1.25 -1.25 x 10. The anterior segment was normal; IOP was 14 mm Hg in each eye. Fundus examination was normal in the left eye and as shown in the pictures above in the right eye.
