Strabismus (crossed eyes) can be treated at each age. Especially in babies and young children therapy has to be initiated as soon as possible. Visual development happens mainly in the first year of life and matures until 8 years of life. Most of the affected children can be treated sufficiently by using glasses, after measuring their dioptries in cycloplegy. The remaining cases nead occlusion therapy, prism therapy and sometimes an eye muscle surgery.
This early treatment guarantees full visual acuity on both eyes, improves binocular vision and long lasting success.
Furthermore orthoptic specialists support the ophthalmologic team and offer possibilities beyond normal eye doctors practice.
Why do patients squint?
Each eye is moved by six eye muscles. This interaction can be disturbed by many factors like an imbalance in the eye muscle tonus. Thus if the brain cannot learn in the first 12 month of life to bring both pictures of the eyes together (fusion) or fusion is not possible because the visual axes cannot be moved parallel, the picture of one eye is suppressed (in children) or older patients experience double vision.
Eye muscle surgery
Eye muscle surgery can be done after children have accepted their glasses and amblyopia treatment with occlusion therapy has brought some improvement. (i.e. patching of one eye) .
How is an eye muscle surgery done and what can be reached with an eye muscle surgery?
By shortening, elongating and repositioning of the eye muscle tendons just right below the anterior conjunctiva a new balance in the eye muscle forces is established. The tendons can be reached by micro incision of the conjunctiva (minimal invasive eye muscle surgery). Thus the recovery period is very short and the patient can leave the hospital 3-4 hours after the operation. Usually an operation takes 20-45 minutes. I recommend an operation under general anesthesia, in adults the surgery can also be done under local anesthesia. Especially trained children anesthesists take care of our young patients.
ORTHOPTIC TREATMENT, VISUAL TRAINING
The orthoptic treatment and visual training includes a complete examination of about 60 minutes by an orthoptic specialist and an ophthalmologic examination.
Orthoptic examination and some parameters:
- visual acuity
- reading performance
- konvergence parameters
- fusion parameters
- motility of the eyes
- cooperation of both eyes, binocular vision parameters
- color vision
- refractive status (hyperopia, myopia, astigmatismus) through skiaskopy in medical cycloplegia
