[Binocular vision after strabismus surgery in adulthood]
1I. ocní klinika LF MU, Brno.
Summary
This study found that strabismus surgery in adults achieved binocularity in only 14% of patients, despite 52% having satisfactory ocular alignment post-surgery. These results suggest limited success in restoring binocular vision after adult strabismus correction.
Area of Science:
- Ophthalmology
- Neuroscience
Context:
- Adults with long-standing concomitant strabismus often have impaired binocular vision.
- Surgical correction aims to improve ocular alignment and potentially restore binocularity.
Purpose:
- To evaluate the development of binocularity after strabismus surgery in adults.
- To compare postoperative binocularity rates with pre-operative assessments and ocular alignment.
Summary:
- 29 adults with long-standing concomitant strabismus were assessed for binocularity (using Bagolini lenses, troposcope, Worth's lights) pre- and post-surgery.
- Binocularity was absent pre-operatively. Post-surgery, 14% achieved binocularity, while 52% had satisfactory ocular alignment (deviation ≤10 prism diopters).
- The study observed lower rates of binocularity development compared to previous research.
Impact:
- Highlights the challenges in restoring binocular function in adults with strabismus.
- Suggests that achieving parallel ocular alignment does not guarantee the return of binocular vision.
- Informs surgical expectations and potential future research directions for strabismus treatment.
