You saw this 59-year-old woman in the clinic last week and just looking at her and hearing a brief history, you made a plan for workup. You found the following:
Vision with best correction: 20/200 in each eye
Axial length measured with the A-scan: OD 29 mm and OS 30 mm
Retinoscopy: OD -15.00 and OS -17.00
The MRI was done and you studied the images that you see here.
Just to confirm the approximate onset of the esodeviation you asked the patient to bring in old pictures and you see that her eyes were aligned in her twenties and the ET was apparent about 20 years later.
