Prism use in adult diplopia
diplopia, skew deviation, fourth nerve palsy, thyroid eye disease, orbital blowout fracture
- Approximately 80% of all adult patients with diplopia are satisfied with prismatic correction.
- Patients with vertical diplopia, specifically skew deviation and fourth nerve palsy, have high satisfaction rates of 100% and 92%.
- Patients with thyroid eye disease and orbital blowout fractures associated with diplopia have low satisfaction rates of 55% and 8%, respectively.
- For horizontal deviations, patients with decompensated childhood strabismus with a combination of horizontal and vertical deviations and patients with convergence insufficiency have low satisfaction rates of 71% and 50%, respectively.
- Careful patient selection, managing expectations, and continued follow-up are critical for the successful use of prisms in treating adult diplopia.
